I had a 97 MK3 GTI VR6 twin turbo. That was the funnest/ most reliable non turbo to turbo build I ever driven that car was neck to neck in reliability with my wife’s 07 Honda Accord 2.4l in stock form. We both drove our cars for 5 years, and both only had to do regular oil changes, tuneup, and tire changes. And mind you that was my first car I actually set out to build. it cost me my high school savings working at ihop. Ended up with like 5k into the turbo build. And another 2k in suspension. And what made it all super nice was the tune. The tune and who you pick to tune your car will always be the factor that determines if your car will be reliable and fun. Or a money pit then a blown engine… DO iT Right. Nd always use oem Bosch parts where you can. NGK plugs, amsoil oil, and Mann or wix filters..
I'll be sure to let you know if it blows up. Because as of right now it's running beautifully and putting the hurt on most the turbo 4's around. Cheers
Ran an eBay 60mm on a stage 2 tune on my gti when I went to get it retuned only thing they had to was adjust for was me putting in larger injectors but even on the stage 2 the car learned when it needed to add and take away fuel. The computers in the mk4 platform are very good at learning and adjusting
Hahhaha. Dude. 24psi 20 hold is going to be the same no matter what. That's where the wastegate is set to open. It does spool a tad later and high end feels better and doesn't fall off as much as k03. I can see what you mean if it was on the factory tune. Anyway. Over 3k mileage on this turbo and still going strong. Taking Subaru's to gapplebees on the weekly. Cheers
@Kuma Ma-kun its simple and direct. Just undo the old stuff and swap in the new stuff and make sure that you use new crush washers on the coolant and oil feed lines on the turbo.
Different waste gate provides more resistance before opening which allows higher boost levels even on stock tune. N75 valve upgrade would come in handy
So is literally every car since OBD2 became common use. And it's known in the audi community that a K04 on stock ecu is a noticeable upgrade. Tuning and slightly less tiny injectors will obviously yield more power but only because of factory boost pressure being a measly 12psi
Thanks so much for this review, I've been looking at this turbo for months and have been skeptical bcuz of the price... Might have to slap one on the ol Jetta!
i bought one from max speeding rod and guess what they threaded the nut on the turbo with right handed threads sooooo when i run it for about a week it un screwed and tore sht up replaced it and i didnt even put it on because the nut was already loose.... beware of that problem if it was left handed thred no problems....
It must be a k04-01 which is a k03 + a little bit more torque. That's why it works fine with current ecu map. If it was a k04-023 or k04-064 it would be a different story.
I’m thinking of doing the same. Have you done it yet? I bought a “stock” b5.One of the previous owners put a 2.3 inch catless turbo back from SS auto chrome on there with the stock tune so it runs kinda rough. It also has an upgraded forge DV. My front mount will be here tomorrow so I might as well do a k04 since I wanna replace the turbo anyway and get the stage 2 plus.
Brayden Nutter you don’t need to. If you push more than 350hp it’s recommended to upgrade rods/ pistons for sure. Better to have a good stage 2 clutch and o2m trans
That play is pretty normal for those turbos, if anything that’s better than normal, as long as the fins aren’t hitting the housing it’s fine, and no it didn’t eat that much oil...
And i spent 175 on my KO4 turbo on eBay...i forgot the sellers name but my high boost was 25psi low was 18psi...it was ok for the money...had it for about 2 years.
What diverter valve or intake do you have because I have a 1.8t ko4 stage 3 catless downpipe and ecs tuning intake with a diverter valve and it doesn’t give the spooly noises like that
Is this just a direct replacement turbo?? I thought I would need to change the downpipe? I’m planning on changing from a ko3s to a Ko4 which is running 230hp at the moment, hoping the ko4 would get 300hp great turbo for the money
1.8t.... #neverlose for anyone who watches donut media or up to speed... both good UA-cam channels. Loved my 1.8t but I think I love my 2.8l VR6 more... just love that sound.
I have the same turbo but can’t get the oil return line banjo bolt on. The one on the top of the turbo it doesn’t want to line up any advice also still have my exhaust manifold on
Most Volkswagen guys will know that a K04 is not just a direct bolt on. Especially if your car was a 150bhp model, in which case the standard form is a K03 setup. For a K04 Upgrade, you need a K04 manifold, you'll need K04 oil lines and a suitable K04 downpipe because of the exhaust housing being in a different place. Then in order to make the power you'll either need a 225 fuel rail with TT or S3 injectors, and a BAM inlet manifold, or just buy bigger aftermarket injectors. You'll also need a lot of little awkward bits. It's not just a straight swap, unfortunately.
@@rabbitgti652 Yes, that's what I'm thinking of because that's generally what a real K04 is. A K04-001 is essentially a K03s. An actual K04 (such as the one from a TT, S3 or LCR) will see a big power increase due to the fact that it's an improved design with different components, rather than being what is basically a factory K03 hybrid turbo
Stylo I agree I have one on my 02 gti and enjoy it. I will be going big turbo at some point I just haven’t got around to doing a big project on that car yet.
Yes yes. There are many different k04 turbos as well. Like all of the mazdaspeed cars use a altered version of the k04 as well as the mk5 and mk6 GTI's. But this was simply supposed to show that you can swap over to this if you have a blown turbo and the boost characteristics did change quite a but. The k03 didn't so very well on the top end power. But this k04-001 is way more happy all of the way up to redline. Thanks for the great input you guys!
@@stevecvntniko8271 if you looking for an extra little bit of power then yes. If your looking for MORE then no. Ko4-23 is another manifold/downpipe/injectors/fmic setup and intake...cost a bit so people slap of a ko4-001 and call it a day. Ko4-23 is 270/75 max so 250whp ISH. If you going to go ko4-23 then look at a cheap gt25/28 setup second hand. That's where the real kick of power is and not with ko3 or ko4....will be more on/off boost with a Garrett but imo VW made a mistake...1.9tdi got the Garrett gt1749 and the 1.8t should have got the gt2561.
@@andrewwright. that's why I chose this turbo. Direct fit but a better boost profile. The k03 peaked faster but fell off at the higher rpm.

Hi, i only watched the video quick because im in work .. i have a mk4 gti , AGU (1999) . I rebuilt my engine and stage 3 remap with the ko4 turbo from the lcr , pushing around 350bhp . What mods did your friend do? Also im not sure about the ko4 there? Was that a sidemount or straight down likw the ko3? Im pretty sure a genuine ko4 has a side mount (exhaust ) so you need to get the custom made down pipe. I run a single decat 3" on mine , Ill try watch the video properly later
Ok so i watched it full. Im not a pro but i dont think thats a genuine ko4 looks like the chinese copy ? Ill upload a video of mine onday if you ever see this comment and see the difference
D4MO tv it’s a k04-001. There are many k frame turbo models. This was the same as a k03s in aspects of simply bolting on. Other k04 you will need a lot of extra work to make fit. Imo not worth it. May as well go big turbo.
Need to do a vac delete on that, it’s not needed and you’ll have less lag. Get it mapped properly too... you won’t be running anymore power but just bolting it on
So is this turbos me exact size as a k03s or bigger..in the beginning if the video he says "sitting in the box is a k04 turbo" bit a k04 turbo has a different design and won't just bolt up to a stock k03s setup I thought??
Did you need to change the injectors for this to work or would it be okay on a stage1 revvo mapp with fmic 3 inch dwnpipe to miltek box 80 mm maff ramair induction would it be okay to take it too stage 2 with out upgrade on the injectors
Hey its been some time now and was curious if the turbo is still holding up. I'm looking to go this route ko4-001 from maxpeedingrods if you could let me know any info I'd appreciate it
A brand new Borgwarner turbo will have some play, not to that degree by any means. But it's still far from "toasted", it's just a different design/style of turbo bearing.
@@r1l3y91ef well then the seals are definetly gone. I've had a brand new k03-005 on my B5 and it had a fair bit of play, I've also had a used 8,000km k03-029 and it was the same, only a little less then your current one haha. Sweet car btw.
hey guys great job! Nice shoots! Question, do you remap your software by you own? i have a TTMK1 APP engine and i would like to upgrate him by my own. Do you have a tip how to modificy my ECU? Thanks guys.
@@TreatsOnTheStreets ok, i understand :D please tell me what about the Turbocharger. is it a simple K04 upgrade? And as i have seen you have a 3inch downpipe right :p
Damn thought the Hulk was in your vid looks like Mark Ruffalo a bit thanks for the info gonna throw one on my 1.8t Jetta cause I can't afford vw replacement cost
With that set up and a proper map can see gains of up to 280 Bhp comfortably at 260bhp you can hear your not even using what that turbo can do, its mapped for a smaller turbo with a earlier prolonged boost now you have a mo4 which usually give you more boost at higher rpm you need to map it it's not getting the air flow
JohnWick KOBK it’s literally almost identical to a k03s which the car was already tuned for. This turbo did help the boost not fall off as much. With the k03 it felt like it fell on its face past 6k rpm. Now it pulls to 7k happily.
lol that old turbo isn't really that bad. also it isn't "leaking out the seals" because there are no seals. The oil is held in with air pressure. Oil coming out is normal.
so have a golf that my dad picked up for $1500 and it pulls WAY harder than this golf and so I’m wondering, wtf did they do to it? It’s a 1.8T like this. It was $1500 because the whole front end needed to be rebuilt. Mine isn’t a GTI either, it’s been rebadged with the GTI and rabbit logo the the 20th anniversary (but mines an 01 so it can’t be the 20th). Very confused, but very fun to drive.
Lol. I fabbed up a k04-022 (from the S3/TT225) to my A4 1.8t and ran it at 29psi. Spike 35😂 that was STUPID fun. Was quick as shit too. I ATE up CHRAs every couple months because i was pushing past the ragged edge of compressor efficiency but it was seriously fun, and i run BATs or large medium frames on all my Audis currently😂. I still loved that k04-022 build😂 i basically downscaled thw fueling on a spicy gt2871r tune i wrote and smoothed everything else out. It was a blast. NOT bolt in. Had to plasma cut a flange and weld it to a tubular header. Highly recommend. I could swap a CHRA in 40minutes or completely rebuild and swap the turbo in at the end of that build cycle😂 moved on because i started SHEARING the turbine shafts😂 happened 2x.
Not to mention I health checked mine, it's the same one as in the video after 2 years. And the turbine shafts and everything had 0 play. I was stunned!
I can't speak for the stock downpipe. I've had a 3inch catless since I was on the k03. But yes, everything went in just as if it were a stock turbo. I'd highly recommend a silicone turbo inlet though. Getting a stock one to fit the slightly larger k04 inlet would be tough.
Guys, bought it twice, max pressure for reliability its 1.1/1.4 Bar, sorry im spanish xd. Mine spiked to barely 2bar and still running, so worth for 124 maxpeeding rods k04 for k03
**How long did it take your buddy to install the new turbo!?!? Its almost dumb to NOT buy this turbo, for the price of a tuneup yer getting an upgraded turbo that has GOT TO last for quite a while i would think!! I wonder if there's another turbo that is basically "bolt in", even if ya gotta switch a couple inlet and outlet hoses, etc, but one that can make a bit more boost and then HP!?!?
There are hybrid K03 turbos that can make up to 300bhp and 320ftlb. They are a direct bolt up, same as any normal k03. The turbo internals get completely upgraded with k04 parts and I believe the housing itself is bored out a bit. So 300hp is the limit without going proper k04-2** or big turbo swap which both required alot more than a direct turbo swap. if you want more info on hybrid turbos theres a great article you can find if you search: 18t tuning uk hybrid turbo advice
@@snoopysnoops7952 I’d say send it. I have another friend who has a mk4 golf with similar miles and he’s done almost the exact same things I did to this car. Even has the maxpeedingrods k04-001. He’s had great success with his too.
@@snoopysnoops7952 totally worth modding. Just make sure to get current with the regular maintenance and make sure the engine is in good health. Then send it on the power mods😎
@@r1l3y91ef awesome. I just installed my k04 and FMIC so I wanted a rough idea after tune. 220whp is decent. In Australia we have the AGU... not as fun as yours 😉🤣
@@r1l3y91ef its bad either way. The exhaust turbine wants to spin one way while the extra pressure has nowhere to go in the charge pipe so it goes back out the inlet of the turbo, (the flutter sounds) thus slowing down the compressor turbine, add in the momentum of the exhaust side and it puts stress on the shaft of the turbo. Enough stress can snap it in half

You can run the k04 on a ko3 tune
You can use a ko4 on a ko3 tune its just way more efficient than a ko4. Obviously it would be more effective with the a ko4 tune but it’s still fine

How long do these run for?
hello, how's the turbo holding? how's the customer support?
Turbo is still alive and well. Can’t tell you about the customer support.
Exhaust setup? Sounds great
It's a cheap Amazon 3inch turbo back with a pypes m80 resonator at the end!

Greetings from Germay. But that "Gunshots" are not loud, compaired to my Golf. But have Fun. I have just mounted the Maxspeedingrods Gt28...
@Chase Robbins maybe a little bit of pops. If you want more, you have to do your ECU. its a little bit difficult to explain that in englisch. sry
Chase Robbins yes, can confirm. I’ve got a straight pipe, K04, tune, it pops massive flames with loud asf bangs
what turbo hose you used that goes from turbo to the air filter
holy compressor surge !!!!!!!! it sounds badass but its nog good!
Watch the coilover video. I explain how I fixed it.
Hi, i only watched the video quick because im in work .. i have a mk4 gti , AGU (1999) . I rebuilt my engine and stage 3 remap with the ko4 turbo from the lcr , pushing around 350bhp . What mods did your friend do? Also im not sure about the ko4 there? Was that a sidemount or straight down likw the ko3? Im pretty sure a genuine ko4 has a side mount (exhaust ) so you need to get the custom made down pipe. I run a single decat 3" on mine , Ill try watch the video properly later
Ok so i watched it full. Im not a pro but i dont think thats a genuine ko4 looks like the chinese copy ? Ill upload a video of mine onday if you ever see this comment and see the difference
D4MO tv it’s a k04-001. There are many k frame turbo models. This was the same as a k03s in aspects of simply bolting on. Other k04 you will need a lot of extra work to make fit. Imo not worth it. May as well go big turbo.
These cars are tough. I have a frankenturbo f21 kit with every supporting mod and unitronic 2+ tune. Cars sitting around 205k and still strong!
I picked up a yellow 20th anniversary a few months ago!!!
Need to do a vac delete on that, it’s not needed and you’ll have less lag. Get it mapped properly too... you won’t be running anymore power but just bolting it on
essex1416 it’s already on a stage 2 06atechnik tune for k03s Literally not very much difference than this k04-001
0:46 Should I remove the black plastic engine cover from my 1.8t? Does that creates less heat?
Yeah get it off dont throw it away though. Clean gunk off of engine bay too
Really enjoyed this content .!! Please keep blessing him with more a4 gti product lol 😂
Did the flautering sounds ever get fixed yet.
Had the same thing and friend ran line to intake manifold and holds boost better.
Yeah just used a diff diverter valve and routed vacuum to brake booster.
I had to get a better diverter valve. I got the adjustable spring rkx valve. My vacuum line was fine.
I did one of those ebay K04's. Worked fine, but does nothing without a tune.
Get a tune! 06atechnik.com has amazing deals and they're great people!
Hows the ebay ko4 holding up??
I love the MK4!
Thank you!
So is this turbos me exact size as a k03s or bigger..in the beginning if the video he says "sitting in the box is a k04 turbo" bit a k04 turbo has a different design and won't just bolt up to a stock k03s setup I thought??
john m k04-001 will bolt up the same as a k03s it’s necessary to have a silicone turbo inlet though.
That car is fresh as fuck for the mileage!
🙏
What turbo inlet pipe did you use ?
I used the eurojet turbo inlet. I think they’re discontinued
whats the exhaust setup on that? sounds really good!
Did you need to change the injectors for this to work or would it be okay on a stage1 revvo mapp with fmic 3 inch dwnpipe to miltek box 80 mm maff ramair induction would it be okay to take it too stage 2 with out upgrade on the injectors
Hey its been some time now and was curious if the turbo is still holding up. I'm looking to go this route ko4-001 from maxpeedingrods if you could let me know any info I'd appreciate it
Hey! Have you bought that maxspeedingrods turbo? I'm interested in seeing if it lasts at least for some time hahaha
@@aerialasturias9785 I have one on my Audi A4 1.8t it’s help up so far reviews are mixed I’m stage too and push 18-19psi but it’ll jump to 20-23

The Worlds largest turbo in the old Volkswagen Golf GTI bro!
A brand new Borgwarner turbo will have some play, not to that degree by any means. But it's still far from "toasted", it's just a different design/style of turbo bearing.
It was passing oil into my intercooler. Haha. It's the most play I've felt on a turbo to this day.
@@r1l3y91ef well then the seals are definetly gone.
I've had a brand new k03-005 on my B5 and it had a fair bit of play, I've also had a used 8,000km k03-029 and it was the same, only a little less then your current one haha.
Sweet car btw.
@@MatWilson2612 thank you! The m3 vs budget golf video should be coming soon!
I have a maxpeeding rods turbo and it rips low key pretty good for the price
How many miles you got on it?
whistlingturbskis Mine has 279k km
Is this a real upgrade? It must be shit cus its sooo cheap
hey guys great job! Nice shoots! Question, do you remap your software by you own? i have a TTMK1 APP engine and i would like to upgrate him by my own. Do you have a tip how to modificy my ECU? Thanks guys.
Nope. We both pay reputable tuners to do it for us. Thanks for watching!
@@TreatsOnTheStreets ok, i understand :D please tell me what about the Turbocharger. is it a simple K04 upgrade? And as i have seen you have a 3inch downpipe right :p
@@Schrauba it’s a straight bolt on turbo from k03
Where did you get the ko4 kit I need one both my best friends have v8s and I’m running ko3 with 5 psi 😢
Damn thought the Hulk was in your vid looks like Mark Ruffalo a bit thanks for the info gonna throw one on my 1.8t Jetta cause I can't afford vw replacement cost
With that set up and a proper map can see gains of up to 280 Bhp comfortably at 260bhp you can hear your not even using what that turbo can do, its mapped for a smaller turbo with a earlier prolonged boost now you have a mo4 which usually give you more boost at higher rpm you need to map it it's not getting the air flow
JohnWick KOBK it’s literally almost identical to a k03s which the car was already tuned for. This turbo did help the boost not fall off as much. With the k03 it felt like it fell on its face past 6k rpm. Now it pulls to 7k happily.
Your golf had ko3 or KO3s? I have a 2004 Mk4 gti 1.8t with KO3s stock, is it worth to upgrade with a KO4?
It was a gls. So it just had a k03.
I just ordered that turbo what turbo inlet pipe did you end up using ?
I had a eurojet turbo inlet pipe.
Can I run this turbo on my Audi 1.8t Quattro
I don’t think so. Your engine faces 90• different
lol that old turbo isn't really that bad. also it isn't "leaking out the seals" because there are no seals. The oil is held in with air pressure. Oil coming out is normal.
The brass bushings sure are seals hahaha. That turbo had way more play than most of the turbos I’ve ever had haha.
I like the exhaust sound!
so have a golf that my dad picked up for $1500 and it pulls WAY harder than this golf and so I’m wondering, wtf did they do to it? It’s a 1.8T like this. It was $1500 because the whole front end needed to be rebuilt. Mine isn’t a GTI either, it’s been rebadged with the GTI and rabbit logo the the 20th anniversary (but mines an 01 so it can’t be the 20th). Very confused, but very fun to drive.
You also can’t assume that the way a video looks correlates to actual feeling.
Was it straight pipe all the way back to the pypes res?
Man I have a 1.8t Audi and it doesn’t pop like that, what tune is he running?
06atechnik.com 1.8t stage 2
What year?
Do you have any over boost problems? running on stock N75? did U log anything with vag-com, any numbers?
No overboost problems. I've been on 06atechnik.com stage 2 1.8t tune for well over a year now. No problems at all.
Still on stock n75
Nice mk4 man! awesome video!!!
How is the turbo now? Still running fine? No leaks or whatever?
Still good. I sold the car about 8 months ago. But I stay in contact with the current owner. He says she’s still going strong.
Lol. I fabbed up a k04-022 (from the S3/TT225) to my A4 1.8t and ran it at 29psi. Spike 35😂 that was STUPID fun. Was quick as shit too. I ATE up CHRAs every couple months because i was pushing past the ragged edge of compressor efficiency but it was seriously fun, and i run BATs or large medium frames on all my Audis currently😂. I still loved that k04-022 build😂 i basically downscaled thw fueling on a spicy gt2871r tune i wrote and smoothed everything else out. It was a blast. NOT bolt in. Had to plasma cut a flange and weld it to a tubular header. Highly recommend. I could swap a CHRA in 40minutes or completely rebuild and swap the turbo in at the end of that build cycle😂 moved on because i started SHEARING the turbine shafts😂 happened 2x.
Make an update bout the turbo
I sold the car. But I’m in touch with the current owner. He’s had no issues with the tune or the turbo.
What’s the set-up on that golf 1.8t to make it turbo
Flutter like that!
no diverter valve, but isn't good for your turbo :/
Im curious how this is holding up still.
still holding strong!!!
Not to mention I health checked mine, it's the same one as in the video after 2 years. And the turbine shafts and everything had 0 play. I was stunned!
@Quévin Santos about 200whp and 230tq. But we will never know actual numbers because I never put it on the dyno. The tune was capable of 250hp 270tq
So is this a direct bolt on from a K03/K03S set up? No need for a different downpipe or manifold?
I can't speak for the stock downpipe. I've had a 3inch catless since I was on the k03. But yes, everything went in just as if it were a stock turbo. I'd highly recommend a silicone turbo inlet though. Getting a stock one to fit the slightly larger k04 inlet would be tough.
@@r1l3y91ef how has it held up so far since the install?
@@Jesse-hr2ef around 7k miles seeing 24 spike 20 hold every day hahaha
So did u just bolt it on, cuz u said it had a little bit bigger exhaust, so can I just swap out the ko3 for the ko4? Thanks
The only thing that wasn’t directly bolt on was it needed a silicone turbo inlet
Did that turbo ever die? 😅
Lasted 2.5 years of 20+ psi
Is the turbo still holding up?
Guys, bought it twice, max pressure for reliability its 1.1/1.4 Bar, sorry im spanish xd. Mine spiked to barely 2bar and still running, so worth for 124 maxpeeding rods k04 for k03
Did you need a new TIP or anything else? Or were they all the same size as the K03?
Yes. You’ll need a turbo inlet. The k04 is larger then a the k03
**How long did it take your buddy to install the new turbo!?!?
Its almost dumb to NOT buy this turbo, for the price of a tuneup yer getting an upgraded turbo that has GOT TO last for quite a while i would think!!
I wonder if there's another turbo that is basically "bolt in", even if ya gotta switch a couple inlet and outlet hoses, etc, but one that can make a bit more boost and then HP!?!?
There are hybrid K03 turbos that can make up to 300bhp and 320ftlb. They are a direct bolt up, same as any normal k03. The turbo internals get completely upgraded with k04 parts and I believe the housing itself is bored out a bit. So 300hp is the limit without going proper k04-2** or big turbo swap which both required alot more than a direct turbo swap.
if you want more info on hybrid turbos theres a great article you can find if you search: 18t tuning uk hybrid turbo advice
Did you change the MAP sensor? You'll get more boost using a 4 bar.
where y’all at in utah?? i’m in layton where did he get the tune? i have a 1.8 audi tt
Hey man! Hit up @therealtooslow on insta. He's the dude with the vw
Treats On The Streets thanks!
@@kilstromkhrono8949 06atechnik did the tune 👍
How was the longevity? Still putting around with that turbo?
It lasted 2.5 years at 20+ psi
@@r1l3y91efhow many miles? I just bought a 240k mile GTI for cheap wondering if I should even bother nodding it with so many miles.
@@snoopysnoops7952 I’d say send it. I have another friend who has a mk4 golf with similar miles and he’s done almost the exact same things I did to this car. Even has the maxpeedingrods k04-001. He’s had great success with his too.
@@snoopysnoops7952 totally worth modding. Just make sure to get current with the regular maintenance and make sure the engine is in good health. Then send it on the power mods😎
@@r1l3y91ef yeah that’s what I’m doing right now all the maintenance, compression was good. Thanks bro 👍
a k04 itself w built internals and bored out w a eurodyne tune
Bigger rods and injectors,
Catless 3” DP
that E36 would not stand a chance
I love eurodyne tunes. 500 bucks gets you stock, stage 1, stage 2 and K04
Where are these turbo's made?
China
Just ordered mine were you able to still utilize the oem turbo inlet pipe?
xX_VEN1X_Xx you’ll need a silicone turbo inlet pipe.
How much HP does the mk4 GTI have with the k04 now?
Probably 220whp
@@r1l3y91ef awesome. I just installed my k04 and FMIC so I wanted a rough idea after tune. 220whp is decent. In Australia we have the AGU... not as fun as yours 😉🤣
What do I need to swap this turbo In I have a 03 gti hatch 1.8t stock turbo
This turbo fits the exact same as the k03. The only part that sucks is that the turbo inlet is a pain to get onto the new turbo.
How many HPsis is the grass in the oil feed worth?
its funny bc that old ko3 turbo looks completely fine...
Except the huge amount of oil it was leaking into the charge pipes.
That turbos gonna blow without the dv hooked up
Hahahahahhaha. Closed throttle compressor surge is literally harmless. Open throttle compressor surge is terrible.
@@r1l3y91ef its bad either way. The exhaust turbine wants to spin one way while the extra pressure has nowhere to go in the charge pipe so it goes back out the inlet of the turbo, (the flutter sounds) thus slowing down the compressor turbine, add in the momentum of the exhaust side and it puts stress on the shaft of the turbo. Enough stress can snap it in half
gfb.com.au/tech/tech-articles/11-the-truth-about-compressor-surge/
You should educate yourself. Closed throttle compressor surge is virtually harmless. Open throttle compressor surge is very bad on the other hand.
@@eddieace345 shot his mouth off with bs he heard from some other idiot and got a little slap on the hand. But thanks for keeping the internet safe jackass
how much HP? I have k03s turbo stock in mi engine and top it's around 280 hp..
220whp is my guess. Never put it on the dyno.
What exhaust does it have I’m looking get an new one for my 1.8t Jetta
It was a custom setup that I made.
Yo I had to stop the video to say this. Guy is rolling his turbo in the grass 😂😂😂😂😂
how long did it last?
It’s still alive and well 😂😂
