Okay my F20 has been sleeved, and high compression pistons were installed from JE. Right now my C/R is 11.70:1, I am adding a 3mm head gasket which should make the C/R 9.32:1 which should been fine for a turbo. I am going to be buying my turbo setup piece by piece, and I was wanting to know what would be some good parts to throw into the mix to make around 400 hp??

 

Well the Maze kit seems like a good kit or even the inline pro sidewinder. Full race as well has a good manifold along with Pfab. 400 Hp you could probably do a gt30 or 5857 if you want a bit more later move up to the gt35 or precision 6265. But would probably get some kind of kit.

 

Do you have any type of budget in mind that your trying to work with?
If not then the Mase Engineering kit is supposed to get your 400whp right out the box with no upgrades and juts the basemap that he provides.
I personally love my Mase kit.

Like revenge has mentioned though, a gt30 or the precision 5857 would be best for that power goal. Tubular manifolds flow better, but the IP cast log style would support 400whp as well.
