Yeah, it would spin the tyres on the rollers in 4th gear, both on 225/50/15 Toyo R888 semi-slicks and 245/50/15 Dunlop SP8000, so we switched up to 5th gear to help with traction.

^Thats the 48 trim .60ar compressor Here

Why wouldnt you want the 56 trim .60 ar compressor (chra# 446179-32)? Here

I know the 56 trim is what I plan on getting in the future.

the turbo can flow 60.8lbs/min so it should be able to get 500-550whp. Not sure about that boost level because I could not find a compressor map to see if its in its efficiency range at that boost level.

SR16VE head /20ve Block
Arias Forged pistons 8.7:1 comp
H Beam rods
+1/+2 oversive valves, mild tidy of ports
Steel headgasket, ARP head and main studs, rod bolts
Tubular manifold
Tial 44mm wastegate
Microtech ECU, MAP sensor, Ignitor box and 4x Bosch coils
Custom built 600x350x100mm intercooler (Prob too big but a left over from the last race car)

LOOKING FOR 400-420Hp at the wheels (FWD)

So the questions to ask:
Cams? I see Kelfords do custom grinds and have somethig for the VE turbo or should i just stick with the 16ve ones?

Injectors? was going to use high flowed red injectors (600cc)

Finally the turbo. Looks like a GT3076R is going to be the ticket, should i go .63 or.82 rear housing? or something else?

.82 housing. It spools the same and makes more power.
