Which 1.8T Should You Build?

When building a big turbo 1.8t from a VW/Audi there are lots of different variations, but does it really matter? So which 1.8t is the right one to build?

The AEB has a cast crank, Agu, bam, apy, aum, amk, bjx, Bex all are forged cranks but there are mush more forged. Aeb and Agu are big port. But on my bam small port head I could easily make 500hp. I also went to stainless steel exzhost valves. Stock pistons are very strong.

[@longgoneg60]

I swapped an AEB in my corrado and although I love it, if I could do it over Id go with an 06A block vs 058. At the time I had all new G60 parts so I made it all work on a crappy worn out AEB. Anywho, great video, appreciate the info. Btw aeb came out in 97, earliest I know of. My block is stamped 97 production date.

[@Dap-Racing]

Awesome video guys! One note for anyone that is curious. with an aeb block if you go with forged rods you need to grind down a small portion of the inside of the block(intake side) to clear the cylinder 2 rod. If you go with a aba crank in an aeb block you need to remove about 60% of the intermediate shaft gear in order to clear cylinder 4 rod. I have pictures and measurements if anyone needs them.

What exhaust valves are better than stock and not $1000 for a set? Currently building a 1.8T with a goal of 350-400whp but more is definitely welcome. Capable of 8000rpm "safely" so springs are a must but I really want this to be a cheap dirty rebuild. Don't judge me! Nothing is going to a machine shop, it's getting a ball hone and new bearings, rods, springs and apparently exhaust valve. Again don't judge me, I have kids and I'm broke!

[@daleevans9029]

Supertech do amazing valves for the 1.8t. Inlet valves are never a problem. Must do exhaust valves as valves fail and the head falls off the stem.

[@GreatLakesLogger]

I have a stroker 1.8t (2008cc). I wanted to drive it and didn't have the time or money at the time to build out the head. It has a EFR 6258 turbo. Is it worth me poking around and finding an aeb head if I'm gonna build one? I'm thinking about buying another head and having it built and ready so I can hopefully swap everything relatively quickly. Do you guys have certain brands you feel make pretty good valvetrain products, or are most of the common brands pretty decent

Not a 1.8t question but about fsi 2.0t, what are the power limits of the stock internals and would i need a hybrid turbo to get to that limit or would a normal k04 be able to get to a safe power level for the stock internals.

I was wondering what your thoughts are on running the vvt tensioner in the head as opposed to non vvt tensioners. Is the extra potential power worth the added complication? lastly, I have a Link standalone ecu, so is tuning vvt on 1.8ts as simple as setting on and off based on rpm or is it variable in any way on these engines?

It's on and off, you can use it to help boost onset. Very easy to install also.

AEB, ADR heads has biger port intake and also have biger camshafts all 225hp engines and 20 pin pistons has forged internals so the 19 pin piston isnt forged and handle less boost

[@MischaGielen]

Awesome video !! What would be the 1.8T engine to go if, like in my case, you want to upgrade from a 1.4TSI (CAXA) exchange-wise? Are there parts I can use from my CAXA to build on the 1.8T? Is there a better fit for a 20V compared to a 16V? I know the airco compressor can be re-used. The power I have in mind is just what's achievable with a good reflash of the chip, as it's a road car and I want reliability.

[@euroberto85]

On the subject of pistons. I'm assuming new OEM pistons with aftermarket rods would be more advisable than using the old pistons out of my 205k mile engine. And on that same note, would you advise just trying to find the 20mm wrist pin pistons since the aftermarket rods are easier to find in that size? My old MK4 is tired and i want to show it some love after 6 and a half years of service.

[@xo7966]

You can reuse the pistons out of your motor as long as they are not damaged. (I.e. valves never made contact). If you have the smaller wrist pins and want upgrade to 20mil wrist pins, then yes, get new pistons

[@matk22]

Aeb or agu pistons. Check piston to wall clearance if your worried

I bought a TT 225 (APX) as a project car, aiming to push it as far as possible while keep it in realiable for its purpuse. Would like to see +750hp crank. VVT or No VVT Valve guide angles? Which? Oversized valves? Which ones? Exhaust? Intake? Both? How big do I need to go on the turbo for the 750hp? G30-900? How much of a difference does going 2L makes, other than spooling? TDI or TFSI crank?

[@sursomsatan1225]

Get on a forum my man, you'll get a lot more conversation out of the people who are there. KZbin really isn't good for that sadly. Unless you live in a very remote area you'll be able to go to car meets and stuff with the people you talk to, added bonus

the limit is 300ft/lb of torque on pump gas "99" on any 1.8t from Volkswagen/Audi/Skoda/seat.

1.8T question: How do you do 1.8t breathers on higher hp cars? Is it normal to have more oil coming up from the head compared with the block breather? Also, could a very restrictive (valved muffler, when closed) to cause a bit more breather blow by? Keep up the good work!

[@matk22]

Change the elbow on the block to a metal one. Then use 19mm oil/fuel grade rubber hose link the crank and cam breathers and either run to atmosphere or to a high flow lol can. And the atmosphere back to the inlet. Personally I run mine to atmosphere to avoid any oil blow by or condensation going back through the system.

@@HidRomail you could run seperate hoses and check. If it's from the head might just be poor oil or old oil If it's from the crank then it'll be due blow by and that's down to work rings. Can do a compression test to see what the engines doing

[@aleksandaraleksandrov8213]

This is very difficult topic, essentially all 20vt are the same but very different when you start comparing engine codes. You should consider engine code when you are going to run stock ECU because thats were the biggest difference is. Some come with narrowband, some with wideband, cable throttle, drive by wire etc etc. Proven combination for low budget sub 500hp is 225hp(if you have later model 150 or 180 with me7.5 just buy a second hand 20mm wristpins pistons) to start with because it has the 20mm wristpin, me7.5 ECU. Buy a set of rods and exhaust valves and thats about it. Turbo choises are endless, very good solution for turbo is a k04-064 from next gen S3 with adapter plate that will give you about 400hp with spool from 2500rpm.

[@COMotorsports]

The engine doesn't care what ECUs controlling it.

[@aleksandaraleksandrov8213]

​@@COMotorsports correct but if you are to start with a car with narrowband ecu, cable throttle body it is a pain converting to later model me7.5 wideband ECU and drive by wire. Again thats if you are planning on using stock ECU and not standalone, if you are going straight for standalone ecu doesn't really matter whichever engine you pick.

[@aleksandaraleksandrov8213]

@MrOki419 Hi, depending on what you would like to do with the car. If you want nice easy to drive quick street car, definitely the k04-064 is the way to go. Rods are a must as well as exhaust valves. Also, you will need a minimum of 630cc injectors, bosch 044, or equivalent fuel pump and decent size bar and plate intercooler with at least 2.5" pipework to go with it, 3" downpipe with ideally 3" catback system and a very good tuner who could make work of the hardware on the stock me7.5 ecu.

To many variables. Small port is good up to 450bhp but even then people have used a small port over 600bhp The real difference will be small port flows better down low in the revs due to port velocity The large port flows better up high revs due to port size and volume over the small port

I want to see you build a AWD. Considering that’s what I have and i want to learn how to pull a rabbit out of a hat so to speak…I love your guy’s channel

[@COMotorsports]

There's a couple on the channel already.

[@joshuapellegrino7915]

Not all wheel drive lol I seen those and makes me want to swap it but I was talking about the AWD head on 06a block has forged crank but none VVT the year before the AWP came out. I love y’all’s all wheel drive content you guys make it seem so simple but it’s very expensive to do! I can’t wait to learn about all the 1.8t no matter what you guys build!

[@COMotorsports]

@@joshuapellegrino7915 Ahh.. but if you watch this video... you will see it really doesn't matter. The different codes are irrelevant. It's basically big port or small port, that's it. So building an AWD head, or AWP or any of the others it makes no difference it's all the same.

[@mattrico1633]

Hey Dave and Clayton I have put in a k04 from apr to my 1.8 mk4 jetta. I want to make more power out of it (around 325-350hp). Will that turbo hold or am I going to need to look into something different?

[@matk22]

A stock k04 even on an engine with the best intake and exhaust won't make more than 300. Mine has a 2.5" intercooler pipe work. Huge fmic them porter exhaust and 3 inch turbo back. And makes 284bhp Your turbo limited at that power. The turbo just runs outta puff

[@COMotorsports]

Buy a different turbo

[@CliffB5A4]

Try a GT2871r, it will do that easy.

My 1.8t question, and you guys could turn this into a video: What is needed for a 1.8t stroker kit to 2008cc! I believe its just a TFSI ea113 crank but I'm eager to know more about it

[@rcm57238]

ea113 crank (92.4 mm stroke), adequate pistons (with smaller compression height and 20 mm wrist pins while you're at it) and 82.5 bore oversize will get you to 2.0 rods are all 144 mm long btw i think u can up the capacity to about 2.1 if you use the tdi crank (95.5 mm stroke)

I have a 2001 VW Passat made in March. It was made in Germany, which is pretty cool. The engine has the AWM code, which is only for 2001. What engine is interchangeable? From the list of engine codes, the only other ones listed for Passat with 170 HP are AWT and AWM. ATW is listed for Passat, but it is only 150 HP. Will the Audi engine with 170 HP work (AMB)? Thanks.

[@COMotorsports]

If it's an external water pump engine then any external water pump 1.8t will bolt right up. If it's an internal water pump engine then any internal water pump 1.8t will bolt right in.

I know you guys said don’t stress between the AEB or AWP heads. How does the VVT factor into power ? Does it restrict what you can do?

No, when you're shooting for big power it's deleted anyways.

Hello COMotorsports, iam planning to buy audi TT 1.8T 132kw quattro manual. What upgrades i will need to reach 400-500 HP?

[@Mk1tt225]

Is the BEA engine any good ? I have it in a mk1 TT with the 6spd and it needs a little work but timings all been redone just wondering what to look for and what to build for making more power

[@COMotorsports]

All the 1.8ts are basically the same, which I think we covered in the video. Only major difference was between internal and external blocks. Yes there are subtle differences, but nothing that makes one much better than another.

[@pilot554]

Excited for Hoopte teardown, maybe it really had rods in it? can never tell with these used cars.

For the Mk7 1.8t what would I need to future proof my engine for more power? Specifically around 600 crank horsepower.

[@COMotorsports]

The gen3 1.8t is a different animal, you're biggest issue will be tuning at that level. You'll want to figure that out first.

[@RickyRussell-uz7jr]

Is the 1.8t 16v worth building upon?

[@electricitize3332]

Bought a 1.8t Jetta….Went completely oem my motor has been totally resurrected/resurfaced. Everything has been gone through besides fuel pump. Got some gauges. My air/fuel ratio is 22.1. Should be around 14.1. Also I was told I need a tune…. New to the vw scene. Starting from scratch with all stock internals. It has a front mount intercooler and full exhaust. Not trying to make a ton of power I just want it to be healthy. 2004 1.8t awp manual 5-Speed. I need tips ab a tune and my afr

[@Austin-bc1yh]

So the "tune" aka ecu flash should help solve your afr ratio unless theres a nasty sensor feeding it the wrong air or fuel intake data

Is all this 1.8T discussion about what in Australia is generally referred to as the 20V? How much if any does it apply to the latest 1.8T 16V? Also in Australia and I could be wrong here the generally desired 1.8T 20V is the BAM.

[@COMotorsports]

The newer 16v 1.8t is completely different than the older 20v. No real similarities.

[@BalticMotorSport]

Also 058 - AEB, AJL has M11 head bolts. 06A - AWP, AWM etc has M10.

Yes correct. The video is way longer than we expected. Point mainly...is if you're building it...it doesn't matter.

Oil sludge is a super big problem with 1.8t VWs. What can you do to help with that? Mines a AWP from a 2003 20th anniversary

[@COMotorsports]

Proper oil changes.

[@dantesinfernopurgatory7826]

Also, majority of the sludge issues are on the longitudinally-mounted engines due to a smaller oil capacity (3.9 qts. vs. 4.5 for the transverse mounted engines). That's why VAG issued a larger oil filter as a fix for the longitudinally-mounted enginesto bring the capacity to 4.5 qts.

Is a 2.0 stroker worth it? Or using an early or later 2.0 block with 1.8t heads? Thanks.

yes. extra displacement is always a bonus. and most people will give away their 2.0 stuff once they 1.8t swap their cars.

Hey, i an new to your channel. I love the content i got a vw mk4 jetta with a AWD 1.8t engine i want to mod it in the future to puch close to 350 to 400 wheel hp what upgrades do you recommend no matter the price to make the car hit that power and still be a reliable car. At the moment is fully oem nothing was ever swaped out buly the privious owner other than all the maintenance. The car also has 128k miles but iwas well taken car of all it life form what i know fron tge perso i got it for i even got the maintenance history that says that all oil changes were done every so 5000 miles. What do you guys think i should do.

[@CliffB5A4]

Just look up tunes for that power value and see what requirements are needed on hardware to support the software. Easiest way really. Main things are upgraded rods turbo injectors fuel pressure regulator intercooler intake and exhaust.

i’m new to the euro scene and the volkswagen/audi stuff. But I just got a 2002 Audi A4 Avant with 1.8T is this a good 1.8T to build up? need advice

They're all basically the same. Slight differences but if you're building one all mods apply across the board.

[@aronbennett4760]

I know that the 2.0T crank can be used to bump displacement up. Can an OBDI 2.0L 8v ABA crank also be used the same way?
