Motor build

[BaconBait]

Doing a long term (probably a year or so) 2.0L build and wanted to know what everyone thinks of the plan so far. I'm hoping for 400+ whp on a 2000 A4 quattro. I'm also swapping the ATW for an AEB. I'd like to keep it somewhat daily driveable, which is why I didn't go for a GT35.

Wiseco 83mm 8.5:1 pistons
Scat Rods 144mm
Forged ABA crank
QED Stage 2 Cylinder Head Upgrade
034 EFI Stage 1c
Innovate XD-16 wideband
GT3076R .82 A/R
Boost Factory custom manifold

I have no clue about cams and would like someone's input. Thanks.

Rough wag on the compressor map.

What management will you be running?

just a question......how much is it to port it out to a 2.0? and how much more will it add?

034 EFI Stage 1c

3652 or 3653...probably the 3653

Do you mean bore and stroke it to 2.0 liters of displacement?

IMO the 8.5:1 compression is a bit low. I would go 9:1 if you mostly want to run pump gas, 9.5:1 for a bit of both, and ~10:1 if you plan on mostly running race fuel.

The one good thing is the 8.5:1 will be a lot more forgiving to tuning mistakes then say a 10:1 setup.

Thanks for the input. I was thinking about going to a 9.0:1.
