So i'm looking into rebuilding a motor for an 05 sti.
I'm wondering if I could run around 400-450hp (built motor) without blowing the stock turbo with a proper tuning?
Parts i'm looking at so far...
ARP Head Studs
Valve Springs and Retainers
Valve guides exhaust/intake
Cosworth oil pump
gates timing belt
engine and trans mounts
injectors (Don't know what size to go with)
Walbro pump 255
Any advice would be appreciated
