Well...I actually had the turbo engine/fmic/ecu/harness/etc... but, I just sold it all a couple of nights ago. I still have a few things to buy for the V8 conversion, but, money is getting split between my Z and my R1, so I probably won't get it done by Christmas (may try and get the install kit as a christmas present from the wife)
Just to add to the above...
I'm definitely going to probably do the V8 conversion, but, I don't think I'll forgo forced induction. My ideal go would be a nicely built LT1 w/supercharger...OR...an RB26DETT...OR...perhaps a Gran National 3.8L Turbo engine...
Either way, in the future, I will definitely go back to forced induction.
I've even considered starting to save up for a turbo kit for my R1...that'd probably be a little insane, though.
