I want to rebuilt the Gsr motor in my coupe from bottom end to top,
Just want to know what's the right parts I can use to for high performance for n/a motor
I currently have super tech springs and retainers
Stage 3 camshaft
Arp h/s (new ready to be drop in but waiting for the rest of my parts)
Golden eagle fuel rail
Guard block
Edelbrock intake Mani with 78mm throttle
Headers
Rest pretty much stock

I want to get jdm itr pistons i don't know if I should get them oversized
Valves ill keep the stock or maybe flat valves
I want to make this built right for all motor
I'm missing injectors and fuel pump
As for that what you guys suggest for fuel injectors and fuel pump?
