Having a 2nd gen RX7 and having taken apart a parts car, I think it might be too wide. If you could fit it in the car, it would probably require the wide fender flares and wheels with a high offset. I do know that 2nd gen rears have been put into Miata's (along with the Turbo 2 motor!).kwilford said:I am no Mazda expert (as I am about to demonstrate), but would an RX-7 rear setup work? I see in my old (1978!) R&T magazine that the first Gen RX-7 was a live rear axle, but the second Gen (1986-91) had an IRS setup. The 3rd Gen also had an IRS, but who can afford THAT?
For some details on the 2nd Gen RX-7, look at
(Ah, the power of a Google search!). With a 56.7 inch rear track width, it's pretty wide compared to the GT at 50.6 inches. Maybe the half-shafts could be shortened up? I suspect that half-shaft mods would be the LEAST of the work for any IRS install. I can't imagine how much work it would take to modify a GT to accomodate the links and mounting points that would be required for an IRS graft.
If we're doing the "flashback" thing, what about an E-type Jag IRS? As I recall, that was all the rage back in the '70's when George Barris et al were building custom dream cars. Which a GT with IRS probably is. JMHO
