I have a precision SC61 Its a t4 turbo and the specs are .68ar 56 trim with a E cover on it. Im planning on using this for my b18c1
rs sleeve 84 mm
endyn piston
crower rods
stock gsr head
jg IM
jg TB
walbro 255lph
720cc
sx fpr
hondata stage 2
equal lenght manifold
3" downpipe and 3" exhaust
tial 40mm wastegate

Anyone have the same turbo as me? I wanna know around what rpm will this turbo spool and around what rpm ill get full boost and also whats the max hp this turbo can support. This is going to be more of a street car that will see the track once in a while. Looking for close to 400whp or so. Any input will be appreciated thanks.

and on the street im gonna be looking for around 320-350whp and around 10psi of boost. will this turbo be efficient at 10psi of boost and with a stock gsr head? redline will be 8k. will the powerband be good?

To give you an idea I made 406whp and 291tq on 12 psi on pump with my T350 SC61 E housing. 9:1 83mm gsr with stock ports in the head.
You should easily hit your goal with 10psi i would think.

any input anyone?

Why not sell it for something smaller. The T4 exhaust is going to add a lot of lag to it.

it will be a fine turbo. I didn't really, notice any lag with mine.(sc61) spool was about 5100rpm@10psi, cant find dyno plot right now.
is this a t4 hot side? if so nevermind
