I am sure this is a beat up topic and has been discussed many a time before, but nevertheless I'd like to ask public's opinion wich 1.8t engines are the most preffered in terms of tuneability and reliability after having been tuned.

I am looking to buy a 1.8t avant, and eventually tune it to 250-300hp. Thanks.[wrench]

AEB is the way to go. But if you are looking for a MAFless tune, AWM is the way to go. The 99.5 is considered the most liked of the B5 A4 for having an AEB with a facelift chasis.

There are soo many opinions on this one.

Tune-ability, go 2001-2001.5.
Best power on completely stock engine with upgraded turbo, Go 98.5-99.5(AEB)

The problem lies in the future mods. When I bought my 1.8T I thought I would never want more than 300whp (rods, turbo, tune, done). Then I learned. If I would have known up front what I wanted long term, I would have bought a 2001.

You can make >400hp on the newer ones just as easy as you can with older ones. You just don't have the AEB head to help you out, but that's only an install away.

I agree but if you are looking for 250-300 I would get an AEB. Then again if you are like me and want more tunability go with a newer model

AEB - easier to work on, external waterpump, etc...

big ass balance shaft, no MAP/boost sensor, dumb rear main seal/bracket design, ... BUT you get a better head/intake.

Newer cars have ME7, very nice for tuning, logging and higher power potential (safely)

my vote is for the AWM. later on you could always go for the AEB head/intake manifold. with the 06A block, stoking it out becomes a bit easier, further extending the potential.

First off the balance shaft has never seemed to be a problem with the 058. Funny thing is that all the A4's making all the big power happen to be 058 blocks.

06A = Sludge monster. lol

I say just buy my 06A block off of me and build it.

AWM.

AWM 2001/ 2001.5 can be a pain in the ass with boost leaks as the EVAP / PCV system is far more complicated (but can be eliminated), but if you plan on staying with the stock turbo then it is your best route, as you can make in excess of 200whp on this particular engine. Very easy to tune, all it takes is a 5 minute flash.

While AEB 96-99.5 (99.5 being a first year of the facelift) is fun, its a little bit easier to wrench on, but it also has it fair share of problems involving costlier components (coil packs are more expensive, ICM failure, ECU thats prone to failure and etc.. )

Ive owned both, current being a 2001.0, and I can honestly say that for the charm I liked the AEB more, but for my current setup and ease of interchangeability with S4 parts (chassis) and the ease of tuning my car, I like the AWM a lot more.

When changing ATW or AWM heads to AEB does intake manifold need to be replaced with AEB intake as well ? What about camshafts, (unless replacing them with aftermarkets) valve cover, etc?

After spending quite a bit reading about advantages and disadvantages of all three set ups I still havent made up my mind. Going with AEB, there is lower initial HP output, but this can be easly remedied, and there is greater potential. While choosing ATW or AWM there is higher initial HP output but . . . Oh well, I think I will have to keep looking for the right car to come up for sale somewhere not too far from me. Price is also another factor but AEB is most appealing to me so far.

Thanks for your input folks.

If you want to use an AEB head then you need an AEB intake since they are port matched to each other. The only way to get around that that I know of is 034 small to large port intake spacer.
