Leo - The engine, RB30DETT (series 2 block with RB26 head), has been fitted :-
I'm using a TT gearbox with a RB bellhousing.
As for the question about the Hardtop, as this is a track car, mostly, I'd like to lose the T-tops. I read a article about someone building a track Z. In the first part he says its a 2+2 then says he's had the T-tops removed by using a roof cut from a donor car out of a breakers yard. I was under the impression that there where no 2+2 hardtops (I wonder if they were available in the US), but I thought I'd ask.
Anybody know if a 2 seater roof panel would fit a 2+2?
