What is the best 1.8T Engine Setup?

What is the best engine setup for your big turbo 1.8T 20v. Do you need upgraded rods or pistons? Or maybe valvetrain or a 2L stroker kit. Maybe you don't need any of it. In this video we set some guidelines based on horsepower goals for what's required for the average 1.8T Big Turbo Engine build.

[@Paff805]

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!

[@Mrnikkisicks]

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

[@20thGTI]

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.

[@TheRebuilt1]

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.

[@115Jester]

Whats a good replacement for the eliminator? You know.. since theres no way to get em.

[@jamilahmed979]

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?

[@20thGTI]

@@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.

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!

[@robbourns2831]

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)

[@patrikpecala7382]

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….

[@jaxon.frandrup]

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

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.

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. 🤘🏻

[@MeltingRubberZ28]

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.

[@paulknight7535]

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. 😉

[@asg936]

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.

[@johan5818]

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.

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

[@COMotorsports]

Short answer, everything.

[@Arturo_S3]

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

[@4BillC]

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.

[@brianlucas93]

Great set up!

[@yankumarrah]

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.

[@4BillC]

@@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.

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

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 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?

[@emeraldcoastreefer4674]

What is a good rwd trans for the 1.8 would be good for a 4-500 hp drift car??

[@MrAngellajara]

Great video, which exhaust valves did you use?

[@COMotorsports]

I believe this is super tech

[@Chrissssooooo]

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?

[@jacklarish4032]

Where’d you guys get that top mount manifold

[@laszloszell8753]

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.

[@COMotorsports]

That information is readily available in depth on the internet already.

[@user-is2hl9uo8s]

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

[@COMotorsports]

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.

[@Fabio_E30]

do You recommend Cast Iron exhaust manifold in 1.8T for bigger turbos like G25-660 ? If Yes can i have brands ? :)

[@johankielblock2601]

Cool video. When you say do exhaust valves, any specific kind or replace with new OEM?

[@COMotorsports]

Upgraded not stock.

[@jims.3987]

@@COMotorsports This is like the third person you didn't tell what kind of exhaust valves. lol

[@collinhuman1847]

Supertech valves!!!!!

[@juansebastiansierracuellar9598]

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?

[@andyrichwoolley5202]

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

[@roybamford8698]

Great video have you thought about doing a tfsi 2.0 bottom end with the 1.8t 20v head ?

[@COMotorsports]

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.

[@115Jester]

⁠@@COMotorsportsyeah i wanted to ask, why a 16v head?

[@whatnext584]

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 !!!!

[@Audische]

Guys thanks for all the info, one question rifle drilled or not ?

[@COMotorsports]

If the option is there and it's a street car yes I'd say rifle.

[@collinhuman1847]

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...

[@collinhuman1847]

Oh yes, it's a 2010 A3

[@monoton9597]

Im curious the horsepower limit of awd O2M transmission

[@antoinemiller1435]

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.

[@COMotorsports]

Appreciate the comments, this video should cover that question, in regards to turbo size we have another video coming.

[@miguelangel9708]

Where do I start, if I want to go from a vr6 to a 1.8

[@DeadlySinYT]

You guys are completly right. I am that guy who put a lot of stuff in the engine and now I get just 320hp and 360N.m. The car is so old (audi A3 1.8T - AGU) from 1997, that now is allways something broke, and with two kids and without extra time, I am trying selling the car. The engine have got rods, pistons, ARP bolts, exhaust valves, valve springs, etc, etc... It was a waste of money, for sure...

[@COMotorsports]

Sounds like someone's going to get a good car to build off of.

[@OPFOR109]

I want to do a MK1 TT so bad. I keep seeing cheap ones on marketplace.

[@dialgia111]

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?

[@COMotorsports]

intake valves don't see the heat and are not as susceptible to failure compared to the OE exhaust valves.

[@SAYMYNAMESOLDIER]

Im planning on building my 1.8 Quattro into a 2.0 stroker. Wanting 450-550hp max. Is a GT28 or GT30 Garrett turbo the better option? I know the lag with the GT30 is significant but is it mitigated enough with the stroker kit? Will not be racing or tracking the car, just want a build that is fun and pulls on average street car builds. Great video BTW!

[@Saltyoldguy-]

Depending on the 28 it won't be enough to make 550whp.smaller 30 frame is probably the better choice

[@jims.3987]

You didn't watch the video at all did you? LOL

[@brianlucas93]

I think the best option in that case is the 3071

[@hansbrekke4784]

What exhaust valves are a good go for the 350hp setup? Seen stock ones die, not fun. Guess its from old age as much as power?

[@COMotorsports]

They're just not up to the heat.
