help with s4 build!
 

I'm trying to build up a t2 and before I do I want to get an idea of what all I need! I'm thinking aggresive street port and I want around 400 hp! I need some suggestions on what to run turbo and injector wise and what tuning software to use. And other things like that! Any suggestions are welcome! Thanks.

what's your budget? who's building the motor? who'll be installing the parts? who will be tuning? there's more than one way to skin this cat so i'll just be real general. you'll need to get the details together after you answer the questions i asked as honestly as you can.

can't go wrong with a streetport.

fish around this section for turbo choices. i have a few that i'm partial to, but ultimately, you'll have to find what will yield your desired results and fit your budget at the same time. that said, take a hard look at the GT35R.

engine management should be your next major choice. budget will be important, but local support will also be a factor.

spend some time penning a solid fuel system for your needs. this is probably not the area to be frugal.

Unrelated to the turbo and fuel setup but if your building an s4 engine in the 400-400+ horse range a s5 rear iron would be cheap insurance.

My sig lists just about all my mods and my RWHP. Pretty close to your goal. This winter she is getting a 60-1 turbo, 1600cc injectors, and a Power FC EMS to get me well into the 400's. ( I hope )
