Wow, awesome replies guys, thanks Zmatt about the turbo info. I was planning on just buying a second engine (M111 Kompressor) and just replace with OEM rods w/ ARP bolts and some JE or Mahle forged pistons. Basically just a refresh, probably skip the headwork as far as porting and cams...just replace lifters and add better valvesprings.
Yeah I figured i was gonna hear that hte stock ECU is crappy lol, I would go with HALTECH over any other standalone, just personal preference. I'm just not good at making the adapter/loom harness, that I would need someone to do for me and I would def pay well for it to be plug and play.
Yeah I have my heart set on a GT3076, with custom log style manifold(reliable N cheap), swain tech coated, Tial WG and BOV. etc etc...
Injectors, i'm not sure about which ones to go with. We have 93 octane so whatever safe limit on pump gas would be, no race fuel or methanol injection.
Like I was saying, a goal of 275rwhp would be plenty, which is roughly 325hp flywheel using 15% driveline loss.
Uber responsive and fun to drive, while getting 30mpg!
