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?

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!

@aleksandaraleksandrov8213 Год назад

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.

The engine doesn't care what ECUs controlling it.

@aleksandaraleksandrov8213 Год назад

@@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 10 месяцев назад

@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

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.

It's a non topic really. Vvt is used to add cold start up but people have used it for tuning as it gives 22 degree cam movement and 22 degree intake cam phase position is good for improving volumetric efficiency down low: even with the intake valve opening "overlapped" into the exhaust cycle, the earlier closure nets improvement in airflow. But only to a point. Past approx. 4800rpm the zero position is more effective.

Great video, you bastards have me looking for 1.8Ts to play around with!!! Lol Thinking of adapting one to the th400 in my E36 for drifting and other shenanigans, or maybe the 996..... Hmmm.

@tptrsn Год назад

Seems like there are lots of AEBs in junk yards around me, and if a set of rods, exhaust valves, and valve springs are all I need to do a lot of dumb things, that sounds pretty cool.

I just picked up a 2002 Audi A4 Quattro 1.8t and I don’t know what is a good upgraded fuel pump on a budget. So far I have Front mount intercooler , ko4 turbo , has a eBay diverter valve, and stainless 3 inch down pipe with 3 inch straight pipe exhaust all the way back. Also what would be good for my next mods

@rkstuntz5278 Год назад

you have external waterpump 058 type block in a mk4 golf in canada (the 2.0l 8v where you talk about)? in europe its also a 06a engine with internal water pump. in europe the 1.8t 06a have also a forged crank, alot of 1.8t's are a AUQ code, 180hp, 19mm pin, forged crank, smallport head, 06a block

@COMotorsports Год назад

No internal waterpump 06a in mk4 2.0l and 1.8t.

@derrickmd18 Год назад

what did you do to the 1.8t block to fit the 16v head?

@COMotorsports Год назад

There's a few things in regards to timing set-up. Nothing physical when it comes to the actual block or cylinder head.

@danieloshaughnessy8476 Год назад

Hey guys, glad to have found your channel. I am pulling my hair out with my cam chain roller count. Everyone says 16 but then it really counts 15. I have tried 16 inbetween notches and it ran terribly, I have 15 in between notches and it runs great. Even my Chiltons book has a poor diagram, that doesnt show truly the correct amount, as we all know the timing marks dont truly line up with a roller or a sproket tooth. Can you or do you have a video that clearly shows this step? Yes there are others out there but they "all" really have a bad video angle, or they just seem to count incorrectly. (I have an 04 Passat auto, with the AWM engine.) Thanks!

@COMotorsports Год назад

Sorry we don't do DIY's, we've discovered over the years that people interpret things as they want and we don't want to be responsible for people trashing their engine because of it. Those folks will likely do that anyways, but we'd rather not contribute to that. There is lots of great info on that engine out there, follow the book and it will run correctly, if it's not then you likely have something wrong elsewhere or your interpreting something wrong.

@danieloshaughnessy8476 Год назад

@@COMotorsports Thanks for the awesome reply, I completely understand where you are coming from. I guess the old addage, is if it aint broke dont fix it. Which to that I would add "but you can still make it better." Thanks again! Shameless plug if you do need a diy on the 09a vavle body for the 1.8T autos, i have a playlist i created to help others not go through the frustration i went through to learn the install!

@danieloshaughnessy8476 Год назад

I was able to swap it out no problem, after closer inspection it was more clear(ish) which roller lined up with the timing mark more than the other, so I went with my gut and all is well. Thanks again guys. PS Ive often thought about taking the longitudinal 1.8T with the front wheel drive and moving it to the back to make a mid engine rear wheel drive car. That would be a build I would love to do, but also love to watch someone else do.

@GreatLakesLogger Год назад

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

@CatsBanana-1983 Год назад

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 Год назад

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.

We made 600whp on a completely stock 1.8t long block. All depends on the setup, turbo size and how reliable you want it to be. Lots of info out there.

Would an AWP crankshaft be the same in a manual and automatic transmission? I need a crankshaft/bottom end, but im not sure if an automatic awp block & crank would work with my manual transmission.

Should be the same block/crank. Although it will likely have a pilot bearing in the crank that you will need to remove.
