Okay, I'll be the as
shole to say it:
Unless you are prepared for the Z to become your "project car" (i.e., sometimes down for a while, random mysterious problem crops up, will need to datalog and or tune at times on your own or are prepared to learn how to do so, willing/able to work on your car at times), I would just hold off at see what 2016 promises for a new Z, which, with a tiny bit of luck, will be OEM boosted.
Modifying an OEM FI car is WAAAAAAAAAAAY less misery (labor of love?) than turning a NA car into a FI car.
Yes, lots of folks have boosted their Z, and it seems that most have done so with minimal hassle.
Then there's the many horror stories and the folks who have a 2nd car to tool around in, making it less of a burden to turn the DD into an experimental test car.
FI on a Z demands deep pockets (relative to, say, an OEM boosted car or a 4-banger), and carries all the usual risks and issues (as well as the cravings for MORE MORE MORE POWER -- cocaine may be a hell of a drug, but so is WHP), plus a few extra ones given that its NOT an OEM FI car.
That said, if you have experience with turning NA cars into FI cars, deep pockets, a second car, etc ect, by all means, go for it.
If not, given that a TT Z35 is looking less and less like fantasy as more reports surface, I'd seriously consider NOT doing this.
I've been down this road. I learned a lot (really, everything I know) about cars, FI, and tuning from traversing that road, and I don't regret it.
That said, its hard to imagine anyone on here with similar experiences would argue with anything I just noted...
Either way, good luck
