yes, the interior on that J30 is rather thrown together with a bastard assortment of faux leathers and cloth.
mayhem,ive been researching and pooling resources for a conversion since ive owned the car, and now that my extended warranty will be up at 100k miles, its time to get dirty.
current plans include getting in contact with craig channer (used a powerdyne supercharger in a NA Z, care of AC removal) so i can see if he has any reccomendations after running such a setup for a few years. Hopefully, component purchases will begin this season. The transmission will wait, because if my auto holds up after engine mods, i will install that shift-at-will system (tiptronic-esque).
i opted against the twin turbocharger setup because of the extreme cost for all the custom fabrication.
the v8 conversion was very tempting for a while, but i am leary of all the quirks i might find in a used Q engine.
for those interested: here is a link to a page with pics/dyno info on that powerdyne setup:
