Hi im contemplating buying a GT30 turbo for my 2wd saff from off here, Its currently running stage 3

Greens
3 bar map sensor
filter
exhaust
Rs500 intercooler
Fresh rebuild not so long back.

Would i need to uprate any of the internals to run this turbo effectively??

Ive just got some new Grey injectors & possibly a turbo cooler.

Im wanting 400-420 bhp??

Appreciate any advice!!

cheers

 

I've got a gt30/71 on my car which has been rebuilt but has pretty much standard internals, I did change the injectors and management though

Standard internals are good for circa 400bhp so you will be fine IF the mapping is done correctly. I'd go for more modern Siemens black injectors if it were my money
