Great video man. Can you do one on the 6.2 hellcat motor explaining the differences to other v8s along with the materials and specs the parts are and strength it can hold for power after modification. Weak points and fixes. After market availability.
For every member here, also for a brand, we learned a lot from D4A's videos. Every video of D4A is always interesting and inspiring. Thanks D4A for making such great content. We feel honored to incorporate MaXpeedingRods products into your projects.🔥🔥
This is one of the best channel out there for petrolheads. I learned a lot by watching D4A videos. In fact it's one the most educative and fun to watch.
I’m running your coilovers on my 96 corolla 4AFE and I love them, my next goal is Supercharging with a SC12 out of a 4azge and D4A will help me understand how to prep and build safely
This is also what I was thinking, start cheap and create a setup to start with and go up from there. I bought the t3/t4 universal turbo from maxpeedingrods, not going to run that much boost on it and it doesnt really matter if it survives or not, because if it fails it is easy to replace with something better.
Driving 4 answers is far and away my favorite UA-cam channel now. I have been a big fan of Engineering Explained and I still love it, but I’ve learned more from D4A than I have from any other channel. Awesome, awesome stuff. Keep up the excellent work!!
I just want to thank you for making these video’s. They are in depth AND easy to follow. Your dry humor make them both informational and enjoyable to watch. 🙏
Massive congratulations again on 100K subs man! Seems like just a few months ago I remember you passing 10K. So far, my experience with budget turbos has been quite good! Really awesome you're working with multiple companies on this upcoming build. :)
I swear I've just begun the same project. Just sourced an FE intake to mount onto my 4AF head... And my cousin is hooking me up with a turbo off of his mk3 Supra. Budget builds hey. Literally just started the build and now I see this video 😁
My brother purchased an MR2 stock when it came out in the mid 1980s. As you know, it was a non turbo. But, you could hardly tell because it ran like a rocket. It was really fun to drive. Nice car mate!
I love your videos man , there so informative and full of knowledge you cover every inch it seems like and at such a down to earth level. I been watching your videos for a couple months now and I just wish I discovered you much earlier. Thank you so much and please don’t stop as I and so many definitely want to keep seeing! D4Answers all Day 🤪😛😁 👏
Great work on your channel and all of your videos. I am all for budget builds vs exotic and unreachable. I am using a ct12b turbo on a 2E-telu starlet ep71 and its sized perfect without creating restriction!
Recently got a newer car and I have the same engine in my corolla. I was planning to mess around with it until it blew up, but idk, might rebuild it and make it my weekend warrior. Deeefinitely gonna keep up with your awesome videos man
I paid $325 for my turbo almost 4 years ago. It is even faster now then when I first started setting it up to make power. And turbo is still in good shape. No play or leaks. We live in an amazing day and age.
Another note. When I got this turbo I got it simply for mock-up for the rest of the systems. But if it ain’t broke, don’t fix it. I thought the same thing as you when I first got it. But it’s good But if it ever blows, a bigger turbo could nearly double my power.
This will certainly be a large turbo for a 1.6L I am looking at getting this size to upgrade my 4th gen 3sgte in order to hit 400hp+ The 4AF will be an interesting turbo motor though with that narrow valve angle it should take forced induction like a champ. Will be a neat build. =D
Thank you for another brilliant, informative and enjoyable video. It's always a pleasure to watch your productions! For the price, this product looks impressive and is very tempting. A used turbo with unknown history could easily be the same price. The comments about manufacturing quality and potential for failure do have merit - but a turbo from any manufacturer could suffer failure because of a manufacturing defect, oil starvation, overheating, or debris entering the system. The warranty would be a crucial thing to consider - because I imagine most aftermarket engine components will only be covered if it can be proven that failure was caused by a manufacturing defect and not by poor setup/maintenance. This product has me a bit baffled though. You're right - they have to save money somewhere, but after going to those efforts on the turbo itself, giving you incorrect bolts and poor gaskets would set you up for a failure and spoils your experience of the product. Could it be that the turbo is manufactured and checked in one place, then packaged with those bolts and gaskets from elsewhere? It's kind of concerning because, 'as received' the product cannot be used; and does the warranty cover the use of other bolts/gaskets that are necessary? I wonder if maXpeedingrods would offer you the correct bolts/better gaskets? You have given me a new option to consider though. I'd like to make a turbo build one day and something like this is now a strong consideration over having a used turbo rebuilt. The video from JK Fab is a good addition too, and as you say, beneficial for you to see the balance and quality before you bought it yourself. Thank you once again for a great video, and for putting up a makeshift video in your road-side garage which may not be that comfortable to do videos in.
Looking forward to the "selecting a turbo" video. Have a 1.6 as well but it has a super long stroke with barely any bore so it doesn't rev high but makes as much torque as a 1.6 can down really low. Was thinking a gt25 or maybe even smaller. The goal is boost around 2-2.5k for daily driving. Don't care about top end. Keep up the great work, love your videos man!
The Garret could easily be 10 times better if the budget turbo only lasts 5,000 miles. Would be interesting to know if anyone has put many hard miles on the budget turbo successfully.
you don't take into consideration their performance. If both the garret and the cheap one can perform very similarly, the garrent won't be 10 times better.
So far 3k miles on mine. Run about 23psi. No issues to speak of yet. They are fed by -4 an and drain is -10 with one 45° bend. I had to port out the internal gate opening. Every time I get in the car I get on it a few times at least. I do use 5w40 Rotella t6 oil, have the water lines hooked up as well.
awsome, somehow you always do what i want to do, I really hope you hook the turbo up with the existing carburetors, at least just to try it out. your videos are great, i always look foward to seeing your videos
Unfortunately won't be hooking it up to the carbs, as getting CV carbs to run with a turbo is next to impossible and the results would be very disappointing even if it did run.
@Eddie Hitler i can second that CV's self adjust to the air flow. I find getting really close by just hooking up a piot tube and down one size on the na main jet with a good regulator.
One thing many people don't consider when looking at a chinabay knock off turbo is sure you could replace it multiple times for the cost of a name brand unit if it dies. But a compressor wheel shattering at 100k rpms can easily cause metal scraps to make their way into the motor and destroy that along with itself. Now the money you thought you saved is gonna cost more than the big name, warrantied turbo was replacing the motor. I'm not saying you can't find a good deal on eBay or elsewhere. Brands like kinugawa and tomioka seem to be well built and properly balanced units for half the cost of a Garret or Borg Warner. Research is key to getting a good deal on a quality product.
This turbo you have you can run for 2 minutes per half hour. But with the Garrett you can run for 15 to 18 minutes per half hour. That is you can run Rally or drag racing, but you could be drift racing with the Garrett. And of course by running the turbo I mean doubling your atmosphere inside the combustion chamber during intake. Allowing you to run on an air flow sensor instead of an air pressure sensor although I still suggest both.
One thing to remind certain car owners. Just because the turbo was cheaper, does not mean the labor to install it will be cheaper. As he noted, it had improper gaskets and fittings. No shop with any sort of a decent reputation is going to install those shit gaskets and some won't have spare banjo bolts just "laying around". I very much agree with everything stated by D4A, but, like him, I can do the majority of my fab/install work. If you can't, don't be mad at the shop you take it to when they rip this thing as a crap kit.
@@ThefeeXP I remember this very well (Project: Yaris Hilton). What I am referring to is that I actually work for a performance shop and we cringe when a customer asks us to install their cheap turbos. Now, most of the time, they are not approaching it from the aspect that D4A is, and they seem to think they found a "cheat code" to get a race-grade turbo for eBay price. The other problem is that we would need a "fuck-ton" (that's a real measurement, I assure you... lol) more overhead to cover all of the missing gaskets, missing hardware, crap gaskets/hardware, all of the time required to get quality fittings and such, and all of the time to fabricate all of the things missing/not quite right about these lesser grade turbos/kits. (A good example of this is Donut media's "Hi/Low" series.) I can have a quality kit (turbo or otherwise) installed in (typically) 75% of the time it takes the cheaper kits because it is all there, and it all fits. As I said in my original comment, that's not a problem for me personally, I would love to start with a $100-150 "disco potato" and figure it out on my own as I am not paying for labor. But, if you (for whatever your reasons may be, need/want to pay for labor this can be a concern if, like D4A, you're not certain this will be your final turbo and, unlike D4A, you'll have to pay for the labor 2+ times to install your turbo(s). Does that make it more clear?
@@deciplesteve I don't know it either. It made sense when I wrote it, but that was after some beers! I guess what I wanted to say is that those turbos are known to blow the compressor blades, sending debris in the engine. Could end up costing more than a brand name turbo. However, for small projects, that require less than 10PSI boost (allowing you to run on 87/89 oct fuel instead of relying on hi-octane) on most cars, these turbos are more than sufficient for the job. Personally, I would go with the smaller units, run on 7-10PSI boost, and bore out the waste gate, so one can enjoy low turbo lag, and an increase in torque; and drive economical fuel, and still stay within the specs of an engine. These turbos shouldn't be bought with the purpose of high boost applications.
@@writenamehere0000 Idk but hey, I inspected mine all the bolts were the same and measured all the sizes for the rods. All is well for me. I work on aircraft engines and sometimes even the big boy brands fuck up too.
My son had one of these budget turbos fitted to his Audi TT, it lasted 3minutes! On inspection it appeared the bearings had failed and the engine ingested metal debris causing major damage. Now he may have been unlucky but I'm a great believer in "you get what you pay for". He payed with paypal who refused a claim on the grounds the item was modified? So caveat emptor folks!
I have this exact maxpeeding rods gt2871r on my 2007 fiesta 2.0 duratec (st150) I did away with the internal wastegate as the actuator wouldn't fit against the bulkhead, so I went 38mm external wastegate. it was only a budget build costing me around £2k including mapping and made 285bhp at the flywheel, it is a little laggy but that's good as the engine internals are stock and to much low down torque is what destroys the stock rods, all in all im very happy with this turbo for the price
I would love to see videos on learn to tune cars, starting from a safe point and doing small increments to improve power until how to determine the limit and stay in a safe reliable set up
I have a 1.8 turbo Audi. I replaced the factory K03 turbo with a $100 Ebay K03 and currently have about 4000 miles on it and only 1 issue. The old turbo pushed 21psi, the Ebay turbo at WOT hits 25+psi then I hit a over boost limiter of sorts and it drops to 15psi and holds. I can hear the blow off when it happens. Needless to say I don't go wide open much. Planning to rebuild the factory turbo and put it back on...
iv fitted one of these gt 28 on my bmw k100 bike with good results so far not a bad turbo im on a budget and cant afford 1500 dollars to throw at a brand name turbo i thought this turbo wasnt bad for what it cost me
Percentage of worsness= difference in rpm it can sustain, turbo efficiency chart, pumping losses/drag....I think there are LOTS of ways to measure the difference between a knock off and the real deal. But I agree, tje cheap one is better bang for buck!
Boznie; congrats! Your just like me. Two seat, mid-engine, coupe. Forced induction is much better than your bike carbs! I have a TPC racing 2nd stage turbo 2.7 Cayman, 5 spd., 380 hp., with Fab Speed high flow cats. You asked for engine topic suggestions and I think the M97, could be a real nich for you. Lots of Porsche guys have very little available information. 🤔😏😄👍👍🏁
That was a fun video, actually LOL time. When I saw MaxSpeedingRods ad a few months ago I thought it must be a misprint. Even though I too would choose turbo over night out, my wife would probably kill me if I bought a turbo instead of taking her out to eat
You need to port out the wastegate passage hole with a carbide burr and a die grinder, (I recommend using an electric grinder as they have way more torque than an air die grinder) they are very small in these turbo's, plus replace the watergate actuator as they have very strong internal springs which will not work well with sensible boost levels, 10 to 15psi. These actuators need more like 30psi to fully open the wastegate! Boost creep at high rpm is very common because of this. After that the 360* bearing is a good idea if you can find it very cheaply, however it probably makes more sense just to modify the wastegate passageway and fit a better actuator and leave internals as they are since its a cheap turbo and if you need to replace it later down the road just buy another and swap over your modified exhaust housing and actuator for a small price. Liking your videos, would like to see you make a video on the BDA/BDG engine, if not also the 2.5 Millington found in mk2 escort rallycars that have become legendary in the tarmac rally 2wd world esp in Ireland. Ken Block has one in his escort. Kind regards Jason
Great informative video, as always. I still await the update on your current experiment with your 4A regarding solid crank pulleys vs dampening crank pulleys.
my friend please port the wastegate hole, I'm having issues with boost creep, the turbo works great but I don't have control on the boost pressure, I have to disamble all again and port thata hole, and thanks for your videos!!!! I have the same turbo on my car
I would choose any equivalent cheap Chinese parts over Bosch made in Germany. The life span of Bosch made in Germany totally changed my mind about German quality. And I would just pick NGK parts for ignition system over any brands. So, I think it is true that customer are more in favour of big brands because they are willing to pay more or a lot more for quality, not just because the brand logo is beautiful. Once the quality assurance is gone, the big brand is worse than the worst.
Hey man, I have one of these on my Miata for about a year now. You should make a video on how to upgrade to a 360° thrust bearing, so I can go over 1 bar lol
Did you ever push it beyond 1 bar? See, that's not a bad idea at all actually. Upgrading this thing might be pretty effective, as the housings and many parts are pretty good. I'll look into it for sure. But I think most turbo rebuilders should be able to do it for you?
driving 4 answers am I right in believing this is a Chinese made turbo? I looked on the link and some of the text looks like Chinese but I could be wrong, I’m very curious because I won’t buy Chinese made things, just don’t want to support the terrible things they are doing.
@@d4a No I run out of fuel past like 12psi at the moment, so i couldn't go over 1 bar if I wanted to haha. I would rather just rebuild it myself with the upgraded bearing, seeing as it's so cheap. The video you showed clips from I also watched, and I was wondering which 360 bearing he had so I could get one myself without it being the wrong size.
@@mj6463 there's terrible things all over the world, from coffee to textiles, to car parts lol. Country doesn't matter when they're all willing to save a dime
I have their gt3582r .82ar and have run it up to 18psi and spiked at 20psi with zero signs of burning oil. And on a stock manifold vg33e-t with a turbo cam regrind it makes full boost at 4K rpm with a .63ar it would be a good street setup but I run at the drag strip.
If you do a "how to pick a turbo kit" video, can you please maybe incorporate tge toyota 2ZZ-GE? I want to turbo it, and i know it doesnt like lots of boost. I think the 2zz would be great to make a turbo video for as it has limitations that people need to look out for.
slept in too much this morning, and cant sleep, thought to myself, I'll jump out of bed and watcha couple videos, lo and behold, D4a has put up a new video 30 odd minutes ago! woo!
Also as someone who is stripping down turbos for ceramic coating from honeywell, garret, holset, volvo and the rest, on the daily, I can say with confidence that they're all pretty much packaged the same as that haha, yours at least got some packing peanuts by the looks of it! hahaha. We get 60kg holset turbos with a bit of expanding foam in the box and theyre fine :D
gotta say too, this thing looks better put together than the $16k holsets we do where one will have nicely machined sealing faces and the next one wont have the faces machined at all hahaha
I'm waiting with excitement for your build, and I trust in your knowledge and drive. That being said, 300HP on the wheels is gonna be near impossible on a 4A-FE, unless you end up changing most of the internals and engine accessories. If it can, I wouldn't imagine it lasting long. I say this cause I think you won't risk the engine, for just a couple of good Dyno runs. I hope you can do it. I also hope you move to the 3S-GTE instead
When it comes to the internals, only the block is staying. I'm really not interested in doing everything twice :) The 3SGTE is an amazing powerplant, but it has been done to death on an AW11, and making swaps road legal in Europe is next to impossible. Well, the 4AFE is technically a swap too, but different regulations apply if you keep the same displacement.
It would be awesome if you do the same but for super chargers later on, everyone talk about turbo but on circuits with lots of curves a supercharger is far superior in terms of stability. Its quite interesting its oil and water cooled, btw if i recall correctly you have to make the valve hole bigger on that turbo or it will overboost, nvm lol.
That seems pretty big for the MR2. Might make your peak numbers, but will likely be mostly lag, followed by too much boost? That said, cheapie turbos are generally a good value. I ran the Garrett GT28xRS on my 1.8T Audi at 25PSI but on a 1.6 not built for a turbo? I used one of the cheapie ebay turbos as a replacement on my wifes Audi and it worked just fine (K04). There's a website of a guy in NZ or Australia (don't have link handy) that has lots of good details on how to make power with the 4age
Cheap parts are great for learning, I will shortly be on my 3rd and hopefully final set of maXpeedingrods coilovers. It would be awesome if they would make a ball bearing turbo. I'm sure it would still be far cheaper than the big brands. Even if it's $350 instead of $150 that's still way better than $1,000+
i didnt watch the full vid. but the main issue is the small wastegateport. you going to have problems with boostcreep. i mountet it on my golf 4 1.8t so i dont know how good its compairable. i buyed a new turbo from aliexpress. an Volvo k16 twinscroll. this budget turbo looks almost 1:1 like the original and ist makes on the 1.8T 400Hp with incredible good response. maybe you try this charger too. but it makes boost so early, its very hard on the internials. sry for my bad english. greetings from germany.
I like this and I see your point but I feel it's important to play devil's advocate a real disco potatoe should spool alot faster than that like 5-600rpm sooner.. and that smaller inducer on both the turbine and more so the compressor. It's gonna make less power specifically up top in the rpms... By my math this thing should be okay flowing 300ish hp but a real Garrett will do 420ish hp and spool faster. Now this cheapo should be more efficient at higher boost than a real disco potatoe so you might make more on your 1.6 since you probably wouldn't get to close to the limits of the Garrett.
I've ran a msr t2871 on the SR20 in my r33skyline drift car. I daily drove it for 2 years and have given it death for another year since. Sure its laggy compared to a bb turbo. But for the cash I'd have one of these every day. Shame their coilovers have issues. Pulls the brand down.
Id still go with somethin with a ball bearing som mayby 400-500 bucks range is probably the best. In sweden we have a great saying about that lagom is always the best
yes the garret is 10 times better , it spools faster (ball bearing) you set it and forget it and will most likely last 10 times more than that turbo . the thing is you probably are never gonna keep a car longer than 2 years with a turbo like this . i wish they made Vband turbos tho , these ebay turbos are great mockup tools for building pipework
Thanks for the info, great video. Do you maybe have any experience with replacing OEM turbos with different variations; new OEM, renewed OEM from shop, renewed original turbo from your car or new turbo from other manufacturers like Nissens, Lucas, Mahle, Magneti Marelli, ... what are good options and why?
I am interested in adding a turbo to a 4.0L Jeep Grand Cherokee. Can you give a rundown of the DIY list of steps to address and comment whether this turbo would be a good fit?
Are you thinking about putting a separate electric oil and water pump for this turbo I am working on it actually on a d5 volvo If you want more of info you can mp me if you want. Thanks for your work I think you will not need the suspension from maxspeed...... I already try it and...!? For 100% use on a drift circuit it will be fine, but for sport road use it not pleased me.

I’m glad my video helped you out in terms of info on these turbos. Appreciate the shout-out!
Watched you're video a while back, was wondering if you plan on doing one about upgrading the thrust bearing ?
maddida Nope. It’s too simple to bother
Great idea to do a real world test with a budget turbo before settling on a bigger brand turbo, very smart and financially savvy.

@Bradius Maximus Not necessarily. You might end up liking the cheap one just fine.
@Bradius Maximus You might end up buying a second turbo anyway if your expensive one fail due to a bad setup
It's all good until the cheap turbo disintegrates and goes through your engine

Looking forward to the "selecting a turbo" video. Have a 1.6 as well but it has a super long stroke with barely any bore so it doesn't rev high but makes as much torque as a 1.6 can down really low. Was thinking a gt25 or maybe even smaller. The goal is boost around 2-2.5k for daily driving. Don't care about top end.
Keep up the great work, love your videos man!
Turbos love big stroke, there's potential there. I'll be explaining soon.
Can you get a ported 5afe head for me contact me @ tallyharry@gmail.com fb facebook.com/TallyHarry1
The Garret could easily be 10 times better if the budget turbo only lasts 5,000 miles. Would be interesting to know if anyone has put many hard miles on the budget turbo successfully.
you don't take into consideration their performance. If both the garret and the cheap one can perform very similarly, the garrent won't be 10 times better.
Too right. It's very feasible that a genuine Garrett could last 10 times longer. It might not but it's plausible
I’ve seen quite a few people now use the maxpeedingrods turbos and they seem pretty reliable and definitely worth the price
Yeah very true, and ball bearing vs journals is a huge difference in powerband too
So far 3k miles on mine. Run about 23psi. No issues to speak of yet. They are fed by -4 an and drain is -10 with one 45° bend.
I had to port out the internal gate opening. Every time I get in the car I get on it a few times at least. I do use 5w40 Rotella t6 oil, have the water lines hooked up as well.
I feel like I got into the mr2 hobby at the right time because he makes all these videos right when I need it.
A 2860 turbo will be a much better choice, unless you are just drag racing.
Look forward to following this build.
awsome, somehow you always do what i want to do, I really hope you hook the turbo up with the existing carburetors, at least just to try it out. your videos are great, i always look foward to seeing your videos
Unfortunately won't be hooking it up to the carbs, as getting CV carbs to run with a turbo is next to impossible and the results would be very disappointing even if it did run.
@Eddie Hitler i can second that CV's self adjust to the air flow. I find getting really close by just hooking up a piot tube and down one size on the na main jet with a good regulator.
One thing many people don't consider when looking at a chinabay knock off turbo is sure you could replace it multiple times for the cost of a name brand unit if it dies. But a compressor wheel shattering at 100k rpms can easily cause metal scraps to make their way into the motor and destroy that along with itself. Now the money you thought you saved is gonna cost more than the big name, warrantied turbo was replacing the motor. I'm not saying you can't find a good deal on eBay or elsewhere. Brands like kinugawa and tomioka seem to be well built and properly balanced units for half the cost of a Garret or Borg Warner. Research is key to getting a good deal on a quality product.
This turbo you have you can run for 2 minutes per half hour. But with the Garrett you can run for 15 to 18 minutes per half hour. That is you can run Rally or drag racing, but you could be drift racing with the Garrett. And of course by running the turbo I mean doubling your atmosphere inside the combustion chamber during intake. Allowing you to run on an air flow sensor instead of an air pressure sensor although I still suggest both.
I am learning a lot from your videos. Thanks man, keep going
One thing to remind certain car owners. Just because the turbo was cheaper, does not mean the labor to install it will be cheaper. As he noted, it had improper gaskets and fittings. No shop with any sort of a decent reputation is going to install those shit gaskets and some won't have spare banjo bolts just "laying around".
I very much agree with everything stated by D4A, but, like him, I can do the majority of my fab/install work. If you can't, don't be mad at the shop you take it to when they rip this thing as a crap kit.
It's a lot cheaper than blowing some pistons, or another turbo. Especially if you install it yourself.
Mightycarmods did an episode about this. They modded a car with a cheap turbo. And made the bill public afterwards.
@@ProDigit80 I have no idea what you're getting at, your response makes no sense.
@@ThefeeXP I remember this very well (Project: Yaris Hilton). What I am referring to is that I actually work for a performance shop and we cringe when a customer asks us to install their cheap turbos. Now, most of the time, they are not approaching it from the aspect that D4A is, and they seem to think they found a "cheat code" to get a race-grade turbo for eBay price. The other problem is that we would need a "fuck-ton" (that's a real measurement, I assure you... lol) more overhead to cover all of the missing gaskets, missing hardware, crap gaskets/hardware, all of the time required to get quality fittings and such, and all of the time to fabricate all of the things missing/not quite right about these lesser grade turbos/kits. (A good example of this is Donut media's "Hi/Low" series.) I can have a quality kit (turbo or otherwise) installed in (typically) 75% of the time it takes the cheaper kits because it is all there, and it all fits. As I said in my original comment, that's not a problem for me personally, I would love to start with a $100-150 "disco potato" and figure it out on my own as I am not paying for labor. But, if you (for whatever your reasons may be, need/want to pay for labor this can be a concern if, like D4A, you're not certain this will be your final turbo and, unlike D4A, you'll have to pay for the labor 2+ times to install your turbo(s).
Does that make it more clear?
@@deciplesteve I don't know it either.
It made sense when I wrote it, but that was after some beers!
I guess what I wanted to say is that those turbos are known to blow the compressor blades, sending debris in the engine.
Could end up costing more than a brand name turbo.
However, for small projects, that require less than 10PSI boost (allowing you to run on 87/89 oct fuel instead of relying on hi-octane) on most cars, these turbos are more than sufficient for the job.
Personally, I would go with the smaller units, run on 7-10PSI boost, and bore out the waste gate, so one can enjoy low turbo lag, and an increase in torque; and drive economical fuel, and still stay within the specs of an engine.
These turbos shouldn't be bought with the purpose of high boost applications.
MaXpeedingRods suprized me with the quality of their rods for my ej25.
I am leaning to buy their turbo too
But how on earth they supply the turbo with wrong bolts and gaskets imprecise? That is a sign of poor quality overall
@@writenamehere0000 Idk but hey, I inspected mine all the bolts were the same and measured all the sizes for the rods. All is well for me.
I work on aircraft engines and sometimes even the big boy brands fuck up too.
My son had one of these budget turbos fitted to his Audi TT, it lasted 3minutes! On inspection it appeared the bearings had failed and the engine ingested metal debris causing major damage. Now he may have been unlucky but I'm a great believer in "you get what you pay for". He payed with paypal who refused a claim on the grounds the item was modified? So caveat emptor folks!
PayPal are the worst kind of human scum.
I love a well dimpled crank.
I have this exact maxpeeding rods gt2871r on my 2007 fiesta 2.0 duratec (st150) I did away with the internal wastegate as the actuator wouldn't fit against the bulkhead, so I went 38mm external wastegate. it was only a budget build costing me around £2k including mapping and made 285bhp at the flywheel, it is a little laggy but that's good as the engine internals are stock and to much low down torque is what destroys the stock rods, all in all im very happy with this turbo for the price
Did you weld the wastegate flap? I’m going the same route on the same turbo
Cool video & idea! Can't wait to hear how it goes. Subbed
Supercharger history!!!
I am really looking forward to seeing how your setup performs and I hope you're happy with your build.
One guy is using a budget turbo on his 1.8L Cruze. So far so good. Just cost a ridiculous amount for him to have a exhaust header fabricated.
Great video's! not very many people have such great info with a not very sober envirement
I would love to see videos on learn to tune cars, starting from a safe point and doing small increments to improve power until how to determine the limit and stay in a safe reliable set up
That's exactly why I started my boost school series :)
Looks awesome dude
Great videos and content. Keep it up mate!!
I have a 1.8 turbo Audi. I replaced the factory K03 turbo with a $100 Ebay K03 and currently have about 4000 miles on it and only 1 issue. The old turbo pushed 21psi, the Ebay turbo at WOT hits 25+psi then I hit a over boost limiter of sorts and it drops to 15psi and holds. I can hear the blow off when it happens. Needless to say I don't go wide open much. Planning to rebuild the factory turbo and put it back on...
Looking forward to this series!
4A-FE: Stop talking shit about me, just wait till I glow up!!
This guy: "We're going to watch your career with great interest"
Funny that your video is talking about the exact same brand as my coil over suspension.
iv fitted one of these gt 28 on my bmw k100 bike with good results so far not a bad turbo im on a budget and cant afford 1500 dollars to throw at a brand name turbo i thought this turbo wasnt bad for what it cost me
Percentage of worsness= difference in rpm it can sustain, turbo efficiency chart, pumping losses/drag....I think there are LOTS of ways to measure the difference between a knock off and the real deal. But I agree, tje cheap one is better bang for buck!
Definitively bang for bucks there! Damn a much easier 2T cylinder and piston costs 2/3 times as much...
Boznie; congrats! Your just like me. Two seat, mid-engine, coupe. Forced induction is much better than your bike carbs! I have a TPC racing 2nd stage turbo 2.7 Cayman, 5 spd., 380 hp., with Fab Speed high flow cats. You asked for engine topic suggestions and I think the M97, could be a real nich for you. Lots of Porsche guys have very little available information. 🤔😏😄👍👍🏁
Amazing video. Thank you brother
That was a fun video, actually LOL time. When I saw MaxSpeedingRods ad a few months ago I thought it must be a misprint. Even though I too would choose turbo over night out, my wife would probably kill me if I bought a turbo instead of taking her out to eat
You need to port out the wastegate passage hole with a carbide burr and a die grinder, (I recommend using an electric grinder as they have way more torque than an air die grinder) they are very small in these turbo's, plus replace the watergate actuator as they have very strong internal springs which will not work well with sensible boost levels, 10 to 15psi. These actuators need more like 30psi to fully open the wastegate! Boost creep at high rpm is very common because of this.
After that the 360* bearing is a good idea if you can find it very cheaply, however it probably makes more sense just to modify the wastegate passageway and fit a better actuator and leave internals as they are since its a cheap turbo and if you need to replace it later down the road just buy another and swap over your modified exhaust housing and actuator for a small price.
Liking your videos, would like to see you make a video on the BDA/BDG engine, if not also the 2.5 Millington found in mk2 escort rallycars that have become legendary in the tarmac rally 2wd world esp in Ireland. Ken Block has one in his escort.
Kind regards
Jason
Agree you have a Good Review
cheap ebay turbos work great, had one now for 20,000miles still working great... IMine is the same as shown here!!!
Great informative video, as always.
I still await the update on your current experiment with your 4A regarding solid crank pulleys vs dampening crank pulleys.
I've been thinking about grabbing one of these for my KA-T build 🤙
Think about grabbing some rods and pistons while your at it
@@griplimit definitely man, still not sure what size to run with yet
my friend please port the wastegate hole, I'm having issues with boost creep, the turbo works great but I don't have control on the boost pressure, I have to disamble all again and port thata hole, and thanks for your videos!!!! I have the same turbo on my car
Nice! A discount disco potato. I remember alot for one during my sr20 days
only thing i can say is instead of the 4afe you should do the "stroker" 7afe, they pair well with a turbo.
Thank you keep up the good work
I would choose any equivalent cheap Chinese parts over Bosch made in Germany. The life span of Bosch made in Germany totally changed my mind about German quality. And I would just pick NGK parts for ignition system over any brands. So, I think it is true that customer are more in favour of big brands because they are willing to pay more or a lot more for quality, not just because the brand logo is beautiful. Once the quality assurance is gone, the big brand is worse than the worst.
Hey man, I have one of these on my Miata for about a year now. You should make a video on how to upgrade to a 360° thrust bearing, so I can go over 1 bar lol
Did you ever push it beyond 1 bar? See, that's not a bad idea at all actually. Upgrading this thing might be pretty effective, as the housings and many parts are pretty good. I'll look into it for sure. But I think most turbo rebuilders should be able to do it for you?
driving 4 answers am I right in believing this is a Chinese made turbo? I looked on the link and some of the text looks like Chinese but I could be wrong, I’m very curious because I won’t buy Chinese made things, just don’t want to support the terrible things they are doing.
M J I’m more for than 100% sure it’s made in China don’t need to look at anything but the price to know
@@d4a No I run out of fuel past like 12psi at the moment, so i couldn't go over 1 bar if I wanted to haha. I would rather just rebuild it myself with the upgraded bearing, seeing as it's so cheap. The video you showed clips from I also watched, and I was wondering which 360 bearing he had so I could get one myself without it being the wrong size.
@@mj6463 there's terrible things all over the world, from coffee to textiles, to car parts lol. Country doesn't matter when they're all willing to save a dime
I have a Maxpeedingrods turbo on my Saab pushing 300hp, its not bad for the money.
I have their gt3582r .82ar and have run it up to 18psi and spiked at 20psi with zero signs of burning oil. And on a stock manifold vg33e-t with a turbo cam regrind it makes full boost at 4K rpm with a .63ar it would be a good street setup but I run at the drag strip.
Love the videos
Thanks for the info!
If you do a "how to pick a turbo kit" video, can you please maybe incorporate tge toyota 2ZZ-GE? I want to turbo it, and i know it doesnt like lots of boost. I think the 2zz would be great to make a turbo video for as it has limitations that people need to look out for.
How am I JUST NOW coming across this channel
I run a t3/t04e turbo on a 1.6l d16y8 honda motor and see full boost by 3500rpm. That gt28 shouldn't be too bad in the lag department
Dude i looove your Videos! Looking forward for more...
slept in too much this morning, and cant sleep, thought to myself, I'll jump out of bed and watcha couple videos, lo and behold, D4a has put up a new video 30 odd minutes ago! woo!
Also as someone who is stripping down turbos for ceramic coating from honeywell, garret, holset, volvo and the rest, on the daily, I can say with confidence that they're all pretty much packaged the same as that haha, yours at least got some packing peanuts by the looks of it! hahaha. We get 60kg holset turbos with a bit of expanding foam in the box and theyre fine :D
gotta say too, this thing looks better put together than the $16k holsets we do where one will have nicely machined sealing faces and the next one wont have the faces machined at all hahaha
I don't know why but I find it amusing that you called it "nylon" instead of "plastic bag." 😝
I'm waiting with excitement for your build, and I trust in your knowledge and drive. That being said, 300HP on the wheels is gonna be near impossible on a 4A-FE, unless you end up changing most of the internals and engine accessories. If it can, I wouldn't imagine it lasting long.
I say this cause I think you won't risk the engine, for just a couple of good Dyno runs.
I hope you can do it. I also hope you move to the 3S-GTE instead
When it comes to the internals, only the block is staying. I'm really not interested in doing everything twice :) The 3SGTE is an amazing powerplant, but it has been done to death on an AW11, and making swaps road legal in Europe is next to impossible. Well, the 4AFE is technically a swap too, but different regulations apply if you keep the same displacement.
Street racers don't need girlfriends.
Only turbos
i have a subaru with a garrett gt28/60 r dual ball bearing = easy getting 330 hp !
That turbo certainly looks like it can support 300hp on a petrol, easy.
It would be awesome if you do the same but for super chargers later on, everyone talk about turbo but on circuits with lots of curves a supercharger is far superior in terms of stability.
Its quite interesting its oil and water cooled, btw if i recall correctly you have to make the valve hole bigger on that turbo or it will overboost, nvm lol.
THANKYOUUUUUUU
That seems pretty big for the MR2. Might make your peak numbers, but will likely be mostly lag, followed by too much boost? That said, cheapie turbos are generally a good value. I ran the Garrett GT28xRS on my 1.8T Audi at 25PSI but on a 1.6 not built for a turbo? I used one of the cheapie ebay turbos as a replacement on my wifes Audi and it worked just fine (K04). There's a website of a guy in NZ or Australia (don't have link handy) that has lots of good details on how to make power with the 4age
Great project, hoping more videos about, good one
Those gaskets look fine installed a gtx 2867r gen two two weeks ago gaskets looked the exact same
Cheap parts are great for learning, I will shortly be on my 3rd and hopefully final set of maXpeedingrods coilovers. It would be awesome if they would make a ball bearing turbo. I'm sure it would still be far cheaper than the big brands. Even if it's $350 instead of $150 that's still way better than $1,000+
But how on earth they supply the turbo with wrong bolts and gaskets imprecise? That is a sign of poor quality overall
i didnt watch the full vid. but the main issue is the small wastegateport. you going to have problems with boostcreep. i mountet it on my golf 4 1.8t so i dont know how good its compairable. i buyed a new turbo from aliexpress. an Volvo k16 twinscroll. this budget turbo looks almost 1:1 like the original and ist makes on the 1.8T 400Hp with incredible good response. maybe you try this charger too. but it makes boost so early, its very hard on the internials. sry for my bad english. greetings from germany.
I like this and I see your point but I feel it's important to play devil's advocate a real disco potatoe should spool alot faster than that like 5-600rpm sooner.. and that smaller inducer on both the turbine and more so the compressor. It's gonna make less power specifically up top in the rpms... By my math this thing should be okay flowing 300ish hp but a real Garrett will do 420ish hp and spool faster. Now this cheapo should be more efficient at higher boost than a real disco potatoe so you might make more on your 1.6 since you probably wouldn't get to close to the limits of the Garrett.
I've ran a msr t2871 on the SR20 in my r33skyline drift car. I daily drove it for 2 years and have given it death for another year since. Sure its laggy compared to a bb turbo. But for the cash I'd have one of these every day. Shame their coilovers have issues. Pulls the brand down.
Id still go with somethin with a ball bearing som mayby 400-500 bucks range is probably the best. In sweden we have a great saying about that lagom is always the best
yes the garret is 10 times better , it spools faster (ball bearing) you set it and forget it and will most likely last 10 times more than that turbo . the thing is you probably are never gonna keep a car longer than 2 years with a turbo like this . i wish they made Vband turbos tho , these ebay turbos are great mockup tools for building pipework
Thanks for the info, great video. Do you maybe have any experience with replacing OEM turbos with different variations; new OEM, renewed OEM from shop, renewed original turbo from your car or new turbo from other manufacturers like Nissens, Lucas, Mahle, Magneti Marelli, ... what are good options and why?
I am interested in adding a turbo to a 4.0L Jeep Grand Cherokee. Can you give a rundown of the DIY list of steps to address and comment whether this turbo would be a good fit?
Are you thinking about putting a separate electric oil and water pump for this turbo
I am working on it actually on a d5 volvo
If you want more of info you can mp me if you want.
Thanks for your work
I think you will not need the suspension from maxspeed...... I already try it and...!? For 100% use on a drift circuit it will be fine, but for sport road use it not pleased me.
This is quite usefull because I'm looking for a turbo for my 1.6L K4M Clio 2 engine.
