Curious can you build an AWM motor properly?

[a4_1.8t_01]

Is this smart to build it for high hp or do most people get a different engine like AEB? What are the differences? Would I be able to put forged internals and run 350whp safely? Thanks.

yes its very possible. integrated engineering makes drop in rods for 19mm wristpins if you want to use the stock pistons. That should easily hold 350whp.

of course... you need to read the FAQs....

I was reading about changing out the rods. If you are going to go that route... why not spend a little more and get pistons and rods with 20 mm wristpins like what are installed with the AEB engines and keep the same bore.

I would think this would not add much to the price tag but allow a safer build. The stock pistons have umpteen thousand miles on them and having new forged internals is never a bad thing. Overkill? Any thoughts?

Yes you can I just did. Only problem was finding the correct main bearings. Awm- with scat rods, wiseco pistons, 034 coated bearings, raceware main studs. Had to send the crank out to be ground down, because of the bearings were to tight. But it all wokred out. I have 90 miles on it with a 3071r as of today.

[a4_1.8t_01]

Ok so you have to get bearings for the rods? They dont come with the rods? I thought those have to be matched. Or can you use oem? So your still in the brake in period? Ok so the bottom end is good for 350hp? Thanks for the input. I want to do this but I need money and time. How much did your setup run you about? quattro 16?

AudiA4_20T (Clint) just built his which would be just like the AWM, might even be AWM, and he documented everything

not trying to hijack, but how hard is it to swap an AEB from a 99 into an AWM car from 2001?

[a4_1.8t_01]

Ecu, Harness. Probably not hard just time consuming.

would the gauge clusters being different matter?

its tempting because i have an AEB that has an MTM ecu sitting in my driveway... I suppose i would need the pedal assembly too... unless i could change TB and run the AWM ecu.... hmmm... the more i think about it the more i don't like it... lotsa little things in there needed to be changed

Not worth it.

a lot of you are speaking out of inexperience. the aeb will go into a dbw car relatively easily. Some fittings and vac lines will be different as well as some emissions stuff like the pvc system. But it is pretty straight forward bolt in affair. no need for a new ecu, cluster, ect.

that would definately drive up costs. in simply IE drop in rods, you do that, just drop them in. gap some new rings, new bearings, or reuse your old ones depending on wear. and all of this is while the engine is in the car..

but with new pistons(which will be in the $600+ range), you'll have to pull the motor and have the cyllinders bored out to match them. which will be another $~500 or so for labor and machine work. then adding the time/cost of pulling the motor. you might as well go 2.0L at that point and get an AEG crank. or keep stock crank and at least go 1.9L..

but the 19mm wrist pins are hardly weak. IE made over 400whp on their 1.8t motor with stock 19mm pistons and drop in rods. no need for an AEB at all. unless you like the head of coarse

[Poopie]

engine builds are tough. you have to pick a budget and stick with it. Its so easy to say "well if i'm spending this i might as well spend some extra and get this...."

before you know it you are way out of budget.

[sean1.8t]

i wouldn't necissarily call that a bad thing.. hehe

[a4_1.8t_01]

Ok so I can go with drop in rods correct? Then keep the stock pistons but maybe put new rings while im there? Thanks.

[JumboBlack1.8]

Any writeups for the "drop in rods" method?

I DID ALL THE LABOR EXCEPT BLUE PRINT AND ASSEMBLE THE BLOCK. IM
15K+ IN THIS CAR.

[a4_1.8t_01]

Damn thats crazy. I will have to wait a few years lol. If you were on a budget though maybe 5k? I would do everything my self.

Yeah, but it's just as easy for him to get an AWM. I'm not saying it isn't doable, but it may not necessarily be financially sound, unless he already has an AEB with $5k+ of effort put into it.
