Hey guys i am currently building an sr20 to go to 400hp and could use some pointers for turbo choice. This is the spec:

S14 bent cam sr20
Cp 9.0:1 86.5mm
Manley rods
Stock oil pump
King bearings
Cometic head gasket
555cc nismo injectors (starting with these and see what they max out at)
Stock cams with vct
Will be running an apw top mount
Turbosmart compgate 40
Turbosmart oil pressure regulator
Haltech elite 1500 ecu

The question is, I was thinking of running a gtx2867r but not sure at what revs will the peak power be. So money wise and power wise which is best? Gtx3071r, gtx2867r or gt2871r?
 
Probs best stick with the 3071r, in your hot climate you might run into troubles with intake temperatures if you run a 2871r at it's absolute maximum.

2871r for about 350bhp, 3071r for 400+ otherwise you'll have to run massive boost if you use a 28

yeah was gonna start low with the 555cc then go for 1000cc injectors for 400 hp.

Cheers, so if i go with a 3071 i will be running much lower boost for bigger power. what rev's should i expect full boost at? I also asume that the peak power will be almost at rev limit with this one compared to the 28.
 
Have a look at the D*Club YouTube channel. They've got 4x cars all running 3071R's on SR20's, all making around 280kw atw
