The question is that the new 265hp Audi S3 has a very similar turbo and develops about 310-320hp only with ecu tune, arriving even at 340 with mods. I think the stock audi cams and better intercooler flow and head is the answer. Stock ecotec cams are very bad flowing.

GT30 + cams and the Gxp/Redline will be really sports cars, that's I'm going to do.

Thanks!

Indeed, Im with you on the choice of turbo.

I dont think you'll really need to change out the bumpsticks,unless your looking for the last 40hp.
Now once they start making bare head castings availible, me & my future wetbench will give you a reason for some staunch cams.

Truth be told, there isnt anything wrong with the stock turbo up to 300whp. unless you need the RPM @ the track. It responds faster than the ETC will let you.
