Here's an R32 conversion, including fully custom dash...
Downpipe clearance with the steering shaft is the big issue. Z32 steering rack bolts in, though. With a single turbo conversion I think that would eliminate all the problems (and make buttloads of power).
The weird looking dash in the UAE cars is from a Bluebird (Altima). I prefer the custom fiberglass and leather one from my link. More work but much nicer.
