I'm going to be a lot more intimate with the 8.8 when the subframe comes down on the parent's 03 Cobra. I'm doing all the bushings (poly subframe and aluminum diff), having a Torsen T2R put in, drilling and tapping holes for a pump and cooler, putting on the cover brace, and doing new half-shafts. After seeing what is being done with the RX7, it got me thinking. Why not a Z car? What are the housings for the R200/R230s made out of? Cast iron or aluminum? If its cast iron, the aluminum housing of the 8.8 should be quite a bit lighter.
May be able to have your cake and eat it too, and maybe without the complications of the C4 rear end. On the other hand, the conversion could be worse. I guess thats why I want to open this discussion a bit more. Just to see how bad it may be.
Any idea how wide a 3rd gen RX7 is compared to a 240Z?
