Hopefully this helps some folks when building their big turbo 1.8Ts.
Much appreciated!! I love what u guys do! It's impressive!!
Thank you it does...
Keep up the good work 👏 🙌 👍 👌 💪 😉
The generation three TSI engine
Besides building the bottom end of the engine
What are you going to add on the top end of the engine and what’s the turbo setup
Is it going be something useable for daily driving
Picking out my project TT right now. Sold my C8 and amg gt and am ready to go have a blast with this. Was thinking 400 crank would probably be a great spot for the Mk1 on the streets. This was definitely very helpful. Appreciate ya!
What's the next biggest turbo you recommend after K04-001? I want to spool quick, but be out of the dangers with the hefty spike I get. I'm full bolt on with APR K04 software, and actually love the performance of this setup, but I am used to this power level and want a bit more. Butt Dyno says maybe between 265-275, but I'd like to see closer to 350 awhp
I have a GT3071R on my 20th, and to me it’s a pretty much perfect turbo set up for a 1.8T. Spools up quick, and has a fair amount of potential for good useable power. Here in the mountains, 350 WHP in a MK4 is a barrel of fun.
Glad to hear and agree with you. Everyone wants these Dyno monsters but rather have something that is fun to drive and scares me a little. 350-400 whp on a mkiv is plenty of fun. I wish i could find a GT3071R as they are hard to find now at least in good shape.
Whats a good replacement for the eliminator? You know.. since theres no way to get em.
Do you have a stock block? I'm at a crossroads on whether I should get rods being I wanted a hybrid k04 turbo at 300 hp. And according to the guy in the video he said that these turbos ruin the rods. Should I get rods or a different turbo?
@@jamilahmed979 honestly, both. For piece of mind. Mine has upgraded rods and pistons, and maybe it didn’t really need it but it’s also nice to not have to worry about it.
@@115Jester I have no clue. Mine is a T3 flange.
Awesome video!! Very excited for the upcoming turbo video.
Going to watch all your 1.8t stuff to learn as much as i can befor i start my build
Thanks for sharing your knowledge with us all the time. You guys are real buds to us all.
Great video. It’s like I just heard all of this just recently. 😂 can’t wait for the next one. You guys are awesome. 🎉
Thanks for giving me more motivation to finish my 16vt, was looking at this to get insight for a buddies 1.8t but now with his swap done and ready to go...the coupes up for this spring lol
perfect video guys tell us about the turbos that are often used in these engines we will wait for the next video great work keep it up :)
Im going stage 2 on my mk4 golf on Friday, had it 18years! love your videos!
Looking forward for the "turbo setups" video! Keep the content coming! Especially 1.8t content!
Needed this so bad. Please keep up the 1.8t sauce ❤️🔥
Great information about 1.8t upgrades! I also have a Fluidampr at 9:20. That was a great mod for my 1.8t! The Gen3 stuff you showed also looked nice. Thanks
Just would be nice if they didn't have so much plastic garbage on the oe setup
great video, boys! Keep up educating the masses.
Looking forward to the turbo setups video!
I love 1.8t's. Super stout platform. A great evolution from the bullet proof ABA's.
I had a customer at the shop I worked at with a built 1.8 in an AWD B5 A4. Bilstein suspension. That was was docile on the street but a rocket on the track.
I have a Stg 3 B5 S4, but have been trying to find a B5a4 for a fun daily.
This video was so informative and spoke of what you should strive for realistically. Will follow.
I appreciate the straightforward information. Your videos are great.
Appreciate the comments, thanks.
🔥Dang, that was one hella intro! 🔥
need to see that gen 3 build. thinking of getting 8V A3. got rid of the mk4 gti just finished b7 2.0t fsi. looking for next project. Love the content as always. You have to do a live feed for the drag car dyno.
Need to hear more about the gen 3 stuff!
Another good one, Thanks guys
Thanks for a very informative video. Im running an AUM 1.8T @ 294bhp on stock engine with K03s hybrid turbo and its been the most reliable car I own.
Logical and thoughtful advice. Thanks!
Dude. Great advice. I think a lot of people wear dyno numbers like a badge of honor. Oh you make 500, well I'll go 600! Most people are more than happy with 350-400WHP. A lot of times even that becomes too much and just turns into a burnout machine.
you guys should do a best exhaust setup video! keep up the great content!
Hey guys! Been watching more & more of your videos lately.. I just picked up a 99 1.8t AEB Passat B5.5 with the O1E 6-Speed last fall @140k miles. $1200! Beautiful car - stored in a garage through our rust belt winters by PO. It's great to have some recently filmed videos showing badass builds on these cars. I won't be getting into fun power adders anytime soon, I've got a bunch of small stuff to conquer first. I've got a full URO parts suspension kit to finish installing. As well as Gates timing belt, new WP, etc to be installed as soon as the weather warms a bit. After that it's straight to K04 & some fun exhaust building.. you guys and some others are BIG motivation for me right now. I appreciate your in-depth explanations that could include newbs like myself to this side of the automotive industry. I currently work in parts at a VW dealership (access to lifts once a week after hours through work), & I have a little less than a decade of experience doing so for other manufacturers.. but all the information you guys share give me a WAY better idea of where/how I want to make my first changes to this car. Thank you!
Your going to get bored of the k04 turbo really quickly. I wish I never would’ve spent all that money and time on everything for that type of set up. It just gets old really quickly and you’re gonna want more power. There’s nothing quite like boosting 30+ psi with these motors! But best of luck with your aeb 1.8t! (Which is what I also have)
You guys make me want to go back to my 4-cylinder roots and build a 1.8t!!!
Really great video.
We need a video like this for VR's
Coming soon!
Love what you guys do and enjoy learning more about the 1.8T's. I may have missed out on a previous video that explains this, but was wondering (for a fwd MK4 platform) what would be the most reliable and capable engine code? I have a spare high mileage AUM engine... Not looking for more than 350bhp and I want it to be useable... Is the AUM engine a good base? Any recommendations for a turbo to pair with it that will spool quickly and still perform throughout the rev range? Any feedback would be awesome. And any recommendations on budget friendly parts would also be appreciated. 🤘🏻
those cartoon bug eyes are so dope bro
You guys do great work! I love my ‘98 B5 A4 Sport - K04 Turbo - Forge DV and silicone air induction tube - high flow cat - custom exhaust - tuned ECU - custom air intake, etc. and it puts down 240 WHP and stills gets 28 Highway MPG, only gets about 16 MPG City, if I keep my foot out of it… which I don’t….
Who tuned it? I have a ‘99 b5 a4 AEB with similar mods. Ko4, high flow 3” cat, 3” exhaust, silicone boost pipes and a stock air box.I want to get mine tuned and was curious how you did it. To my knowledge the ecus are kinda hard to tune on the pre facelift models like ours
@@jaxon.frandruphave ecaconcepts tune your car
Here it is a new whitening light in the dark COMotorsport video.. many thanks to Dave & Clay.
Would love a video like this about the 15 plus 1.8 and what the differences are besides turbo and stroke on the gti and R ECT over the ae888 1.8
Love my EFR6758. Pulls smooth and hard.
On point about (build it for what your gonna use it for)😊😊😊
Totally agree. But I would add the crank and cam bolts and vct delete for over 300hp. I've had those take out quite a few 1.8t's even using new OEM parts
crank and cam bolt aren't required for those power levels, they will take you a lot further.
Piecing together a gt3071 kit for my awm b5. Good to know about the exhaust valves 👍
great vid !!!!
I have a mild build big turbo wagon. It's fun for what it is. I will have to get a couple more things for the motor. I drive it almost everyday.
Thanks!
As always it's greatly appreciated.
Great video great advice I'm running 450 crank 420 torque on fast road 1.8t it's more than enough I spent out on the rest ie gear box clutch 4 wheel drive controller suspension loads of guys chasing the sun but if u can't put it down it's a waste.
😉
S3 8L stroker street car with around 580whp give or take on a G30-770 currently and will be changing to G35-1050 in the new year, hoping for around 650whp. Drives beautifully with a DQ500 fitted instead of manual 02M.
I can confirm it, with a big turbo you loose so much fun and happynes while driving it daylie in the streets traffic.
With the 6speed manual gearbox it was a nightmare to spool up the 6266gen2, now with dsg it feels much quicker ( and actually it is ) and feels like a different car.
I have had B5s for well over a decade, have had many of them, done MANY builds for myself and others (professionally and in my own gig) currently own 5 audis in my driveway rn, 2 1.8ts rn, stage 3 S4, 4.2 S4. Even with a super clean S4 i swear i have as much if not more fun in my B5 A4s😂 ive been building my B5 for all 10 years. Car got totalled and i literally moved the engine and everything over to a new one😂 it depends on what ypu are looking for. Ive had tons of fun fabbing up everything from large small frame turbos (non bolt in k04s) at the ragged edge of compressor efficiency, to custom BATs. Imho right in the middle is best. Gt2071r is always a goody, reasonably low lag and decent enough pep. T3t4s have a pretty large span of sizes that work well, even for some big power, Had a custom hybrid holset Hx35 Hx 40 professional wheel with a smaller exhaust housing that was tons of fun. More lag but better than most large frame turbos and still had a usable power band. IE rods, buy once and never worry again about anything you do. Ecs RA4 smfw and a B7 RS4 clutch and p.p for a good cheap clutch thatncan handle good power and drives phenominal. Valvetrain if youre pushing above 8250 rpm because you will 100% get valve float like clockwork at 8250. Midsize medium frame turbos are as about as big as youd want to go for decent driveability. Honestly the 5 speed gear ratio from the 2.8 v6 B5 is my favorite for 1.8ts. Little longer gear little more time in tge powerband without constantly having to drop out of it like the 01E does
You made my day, I wanted the 500hp 1.8T but inmy country everything cost at least 70% more that in US. After watching this video I think I just need maximum 400hp because it is for a street car, daily. What do you sugest about turbos? I am looking at Garret GTX2867R GEN II. I am going to get some forged rod and pistons , and now I will need to change valves as you mentioned and spring. Thank you so much!
Nice video, I'm on a build myself,

The car is going to be 300hp daily driver. But I want to have the choice to swap map to 500.
great video ❤ id love to know more about how the 2.0 set up performed, i got a deal on new crank for a 2.0 build but your vr6 video is making want to sell it all and go to the darkside 😅😅
I have a 2l and a vr6 4 motion at 260hp, I enjoy driving it more than the 2l and the sound .....
honestly I think my current setup is the sweetspot for a street build, 81.5, 9.5:1 CP pistons, ibeam IE rods, ferrea valves, springs, stage 2 cams, ie intake, precision 5858 turbo... and a permanent awd setup, all the good stuff for 500-600 hp range, haven't dynoed yet
IE rods and a hybrid K04 is just good times lol. Rods are a must tho
my b5s4 burnt down so i bought a s line b5a4 i plan on building👍
When I've finished restoring my Audi TT's suspension and getting it as tidy as possible I'll be looking to make around 350-400whp. I know what ths kind of power level is like as I've had a few cars this powerful and thats perfectly adequate for street driving and then some. 😊
I just got done building a 1.8T. All I did was BC valves, Supertech springs and retainers with IE rods. Everything else is stock or a simple replacement, like rings and bearings. It's not in the car yet but with a gt28 (it's a daily) I'm hoping to get 400ish to the wheels and 8000+rpm. Fuel will be E85 and methanol injection.
Great set up!
Have the same with my A4 (B6), it’s nice to comfortably rev out to 8K and have margin.
It’s so fun, I do wish I went with full frame GT28 though. I have the GT2860 eliminator so it fits K03/04 manifold.
@@yankumarrah mine isn't in anything yet. I have a FWD B5 a4 and that was the plan but I recently got the chance to get an awd B5 a4 with no engine and unknown condition really. So idk what to do. But it's been a pain, if I would have went your route I wouldn't have a K04 on my car now. Currently makes about 300whp on E85 and methanol injection so it's fun but a week ago the clutch stopped working. The pedal feels normal but doesn't disengage the clutch. All the gears work if you float them, so just don't stop right. Lol...
@@yankumarrahSounds similar to mine. I just installed a fully built and ported AEB head on my stock AMB block. Using a billet 28rs on Apr manifold. Happy with the setup. I have a 2867 turbo I may throw on it soon since bigger turbos seems to work well on these w/ stock rods as Dave mentioned.
No they don’t! You will throw a rod out the side of your block! I did with a hybrid ko4 with about 330 hp
ESE MOTOR ES HERMOSO A SIMPLE VISTA!!!!!!
good discussion and love the 1.8T talk. Bigger question is what do you guys sell or have access to for the 1.8t to make this 300-350WHP range. The Garrett GT's that used to be ATP turbo are long gone so other the T3 or T4 I dont see much options. I could be wrong though.
Thanks again for all the knowledge transfer
Short answer, everything.
Great video guys learing everyday from your videos , I have a audi s3 8l awd 18t std bore, 20v. Ss exzhost valves. HBeam rods IE rifel drilled, G25-660 emu black. 1000cc injectors and high flow fuel pump with watermeth injection . Never tuned her on a dyno, only some road tuning. Boosting 1.8bar with a egn timming of 11degress. Afr under boost 11.2. But the car feels a bit slow for that boost level. Our fuel rating in SA 95 octain.
Timing to low, give it way more over 4000
Hand it over to an experienced tuner with a proper dyno to get the right timing out of it
I will do thanks for the support guys
I had a b5a4 with drop in ie rods , comp 5152 turbo stock head intake, that made 377 awhp on 93 pump w/m injection
Love your content! I just bought a 2002 Beetle Turbo S. It's my 6th VW. Daily driver. What is a good setup for around 400hp? Eventually I'd like to make it awd as well. Thanks
Hi,
the turbo video would be awesome if it listed the other neccessary parts too. Like do you need injectors? Fuel pump? A new clutch etc.
Thanks for your content!
We have a video of how much the hooptie cost, it goes threw most everything.
Funny kus thats all i did to mine. IE Rods, Supertech Exhaust Valves, Supertech Valve Springs, ARP Headstuds and a ebay 3071R , made 403 been like that 2years now. If i had to do it again, ill do the same thing. Its a daily.
Videos id like to see.
Transverse to longitudinal swap, like AMU into an AEB A4.
A strictly street build video 250-350hp-ish and how to get that power out of AWD, FWD, and RWD
Available tune options to achieve desired results.
Must have tools, tips, and tricks on Audi VW engines
Traverse to longitudinal... If it's just a 18t just swap so the longitudinal stuff in the transfers engine. The engine itself is the same.
Tons of 300-350whp builds on our channel already with different tuning.
Can you do a video on your ideal 2.0t build I know the 1.8 an 2.0 are the same just bigger bore but I feel like there a higher ceiling for the 1.8 an the 2.0 kinda only has a few routes. I’m curious about a stocker set up forsure just don’t know where to start
I'd like to see a similar video with the EA888 since they are creeping on 10 years old.
This makes me feel better about my decisions, my goal is 350+ whp just a street car with my 1.8t. Im about to order some IE rods. Should I get rifle drilling?
More videos on the gen 3 please!!!! Thank you for the content.
Facts
It will be similar to the 2.0l gen 3 as it's basically the same engine
I have a 2004 Jetta 1.8t original motor/turbo ko3s, apr tuned stage 1+, and 250k miles and it runs so perfectly, I will be buried in it. I did replace a lot of parts I didn't like, mainly for performance purposes. Paid 2k$ for the car, parts/labor for the extra were 4k$, 6 years ago.
Ima go catless downpipe and CAI with a tune, is there a noticeable difference in performance?
Did you make a video how to build a reliable 1.8T for daily street use? I'd like to upgrade my 1.4T (122hp) to a 1.8T. If possible something without direct injection to prevent carbon buildup on the valve stems and in the inlet.
You guys should do the same video but with the 2.0t version!!! FSI and TSI. Any chance of that happening?
can you talk about what is the perfect transmission set up now.
Any chance of going some videos on the ea113 2.0 tfsi motors?
Just a idea, but could you make a video about the sai delete and the n112,n249 ,vacuum,pcv all the hundreds of hoses delete? Basically shaving the engine bay. Of course some we need it so you could explain what they do and why we need them or not.
That information is readily available in depth on the internet already.
can please do this for the ea113 please 🙏🏼
I used to have a 1.8t 2001 GLI back in the day I’m on my 2024 GLI now and thinking I’m probably going either IS38 on a low torque file or FBO Stage 2 E85 if Unitronic ever comes out with a E85 file for Gen 3 2.0T. I agree that people get caught up in the numbers instead of having usable power or just don’t even think about their application
Perfect explanation.
I have a 20th GTI with a fully built motor, built transmission and aftermarket clutch. The goal was to go bug turbo. This year I bought my 7.5 golf R and the stock 300hp has been a blast! I haven’t even put more time into the GTI and going big turbo like I originally wanted, my GTI stayed at a stage 2 210hp and my stock 2018 golf R is my favorite car still. My mk4 GTI always gives me little problems and I got tired of it, with over 15k in parts and it just sits. I got greedy when I was younger and now it sits. 300hp should’ve been good but I bought into the hype and now my stick golf R gets all my attention
no gli was made in 2001 with a 1.8t
I was hoping you would talk about clutch requirements!
You'll need an upgraded clutch. lol
can you make this same style video for mk5 and mk6 2.0t 07k 2.5t and vr6t 12v and 24v
I’m running stock internals, techtonics 2.5 downpipe, 2.5 techtonics magno flow exhaust , stage 1 united motorsports tune, and a cold air intake
What else would you recommend? It’s my daily. I’d say it’s possibly some where in the 235-245 hp arena but not positive. United motor sports only posted their boost but not so much the actual gains in power. It’s been running great, I love my 2003 1.8t. I can’t think of anything else to get more power without having to start spending a lot more money ( cough; bigger turbo)
Thoughts?
Great video, which exhaust valves did you use?
I believe this is super tech
What about awd vs fwd? and how those transmissions handle the power
Hi from malta leon cupra r 225 my setup is forgd rods all the supporting for hybrid k04 pushing 30psi 340bhp is a rocket
Great video have you thought about doing a tfsi 2.0 bottom end with the 1.8t 20v head ?
It's all the same stuff. The better option IMO would be 1.8t bottom with 2L FSI head. Thats what I was originally going to do with my drag car but cam and lifters were not as ideal so I stick with the older 2L 16v head instead.
@@COMotorsportsyeah i wanted to ask, why a 16v head?
Hi iv GT a 2003 auq 1.8 20v turbo and when I start first thing on morning it struggles to start 2 times then goes ok wud it be a coil pack out ? Or any ideas please thanks
Ok I have a gen 3 Audi a3 1.8tfsi
It is a daily - I just want it to sound good and have some fun in it - I’ve got a few bits and bobs on it like I commented on a pervious video I got it mapped and it’s not running to go so I took it if the road I may have a crack in thermostat housing but my question is I’m looking for around 350/400bhp to the wheels and around the same in torque what would I need for this as it’s still stock internals and stock clutch set up and stock turbo although I dose have stage 2 map and gear box map done with the stage 2 supporting mods such as 3 inch decat 3 inch non res to dual pipe at back big charge pipes big intacooler big turbo elbow and air intake better spark plugs and coil packs and a better diverter valve I’m actually thinking putting a resonator back in it haha just want it around that 350/400wbh mark will I need fuel pump or turbo upgrades or clutch upgrades ?
Hi, my setup: k04.023 turbo, 4 bar fuel pomp, 630 Bosch injectors, 3 inches sensor, big intercooler, steel tip, 3 inches downpipe, 2.5 exchaust. Can I get 320-350 hp??
I’m actually refreshing head. Should I change exhoust valves?
Love your videos . I am from South Africa busy building a 1.8t 300hp not more than that what do you think of cold air intake does it matter thankyou
It's unlikely you're keeping stock intake on any 300whp capable turbo so not really much to discuss, it will need to be replaced.
Cool video.
When you say do exhaust valves, any specific kind or replace with new OEM?
Upgraded not stock.
@@COMotorsports This is like the third person you didn't tell what kind of exhaust valves. lol
Supertech valves!!!!!
What is a good rwd trans for the 1.8 would be good for a 4-500 hp drift car??
Here in Latam we had Jetta A4 until 2014 (Jetta mk4.5 - or Jetta Clasico GLI search for it, it is just a facelip), I own one of these, with only 60k miles, but it is automatic, can the Tiptronic transmission handle up to 300hp?
do You recommend Cast Iron exhaust manifold in 1.8T for bigger turbos like G25-660 ? If Yes can i have brands ? :)
Dude I got smoked on a 2005 avant 1.8t head had a crack bought a new head turns out it’s from China now dude won’t do a return I would take stock power lol instead of a good winter driver I have a winter project that’ll need up going to junk yard it’s a shame to say I wick I had money and know how like you bro keep it going !!!!
Where’d you guys get that top mount manifold
Guys thanks for all the info, one question rifle drilled or not ?
If the option is there and it's a street car yes I'd say rifle.
l have 1.8T AWT its all wheel drive and 5 speed manual, currently stage 1 with remap and air filter, it is with a K03 turbo and its around 190-200hp, l wanna go stage 2 and achieve around 280-300hp. l use the car as a daily/street car. What should l upgrade, what would you suggest to achieve that?
Do you just reuse old intake valves? Have seen quite a few failures due to old intake valves. Could it maybe be related to worn guides which makes them hit crooked on the seats?
intake valves don't see the heat and are not as susceptible to failure compared to the OE exhaust valves.
Would love to see an equivalent for a turbo Mk4 24v.
We're going to do a similar VR video which is going to cover most of them.
I want to do a MK1 TT so bad. I keep seeing cheap ones on marketplace.
You guys should do this video for 16v/aba ok maybe I’m pushing it with asking you guys to include aba block, but for real do the same video for 16v.
Very small market on that one. Obviously I run a 16v head on my drag car but they are far and few between now a days. It really all comes down to power goals, I've gone through them all in my 16v's over the years.
So I guess I over built my 1.8t lol Can’t wait to drive my drag car with my setup hopefully she does great.
Best of luck.
It seems like you were mostly talking about parts to keep the engine more reliable. I know you said that you are planning on a turbo video. I would like to hear your thoughts on other power adders (camshaft; intake manifolds; larger valves; big valve head etc...). Thanks guys!
We may do a video like that, we'll keep it in mind. Thanks.
@@COMotorsportsplz do a video like that!!!
I have a question, I wanna build a 1.8T but supercharger, make something different, to make around 300WHP and extremely reliable, do you guys accept If in the future I contact you guys and you give me a price, and I can send the engine for you guys to build it for me and then ship it back ready to mount? Do you do that kind of job? Can you accept a supercharger build or just turbo or non of that?
Great job as usual, we about to strip my son's oil guzzling Audi A3 Tfsi 1.8t, it has 82.5 mm pistons, not sure if thats correct, can we use the 2litre 82.5 mm piston, there isnt alot of info around, or nothing I've found.... i hope you can help...
Oh yes, it's a 2010 A3
What dose it take to make a reliable 350-400 whp daily audi a4 Quattro,almost done wit suspension and drivetrain upgrades. You guys always have great contact always enjoy watching your videos.
Appreciate the comments, this video should cover that question, in regards to turbo size we have another video coming.
Please do a VR6 vid like this. I have already started on mine, but I would love to see the vid. I have a RUFF supercharger setup, but I cannot afford the tune yet. I was quoted like 3K for the motor tune and another 2k for the trans. I would LOVE to have you guys tune it, and I would make the drive from Kansas, as long as I could beat that price. It would make for a great video! I know how much you love superchargers LOL
