I spoke to dave on the phone for like an hour and a half a few weeks ago. His kit comes with new injectors and an AFC already tuned for the turbo kit, it has everything you need, comes with the intercooler, all piping (cutsom made by Injen
).. he said you will not need to drop another penny on parts. Optional parts he reccomends are a turbo timer, an exhaust temp gauge and a boost gauge, just to monitor everything (not included in the kit). He said the ONLY long term effects of the (200whp) 6psi boost MIGHT be that you will burn out your clutch a tad sooner, but only because people tend to punch it at higher RMPs because the turbo spools at around 1600RPM.
