600hp turbo c5?
Either 60 or 80lb injectors
Wide band
Boost gauge
Alky control (if you want to be safe)
Decent cam
Good valve springs(btr)
Clutch to hold the power
2 bar map sensor
Lots of odds and ends trust me lol
600rwhp is very doable but really depends on the tune and even still is in the pushing it zone for a stock short block so nothing is promised
