400hp build

Hey guys im building a 400whp street car, not sure exactly what turbo I want to run yet. I've done some research but mostly on garret turbos and was wondering if anyone had any better suggestions, (I bought a built motor so if cams ect are weird or something idk)
 

Car is going to be mainly for drifting and street use
I want to go responsive as possible making that power

So all I currently have now is the long block with stock intake.
Here are the specs

je pistons
scat rods
arp head studs
arp main studs
mls head gasket
tomei 260-11.50 cams
tomei cam gears
tomei valve springs
tomei retainers
tomei ras
new rocker arms
new timing chain ect
extra capacity sump
calico bearings
with cas and intake manifold

So currently I'm thinking GTX3071r .63 or gt30r

thanks in advance

the gtx3071r will make the power that you need.  if you are going e85 i would go a smaller turbo again.  400hp is very easy to achieve and you could get there on a stock motor without too much hassles

I've been running through this same turbo question.

 

Hypergear ATR43G3SAT external gated and BB seems to be the winner for me. ATR45SAT if you want headroom to make more power which with a built engine you'll probs want in a year or 2.

Check out holset turbos in particular hx32. Crowd in england called compressor racing sell them. Look at their website. Cheap and reliable turbo too.
