20B single turbo - Rx8 or Rx7?

Hi, So I have a 92' Fd in reasonable condition (mine since 2004), stock twins, PFC, ported, rebuilt etc, just ran 327hp on WGT's dyno in the UK, but I wanted much more!

Made a few enquiries and now I own a D series 20B ready for rebuild. There are lots of options of what to do with this, I have pretty much decided on single turbo, street ported as I want around 550hp. Its off to WGT next weekend to get the rebuild started.

My dilema is what car to put it in? Rx7 or Rx8?

Rx7 is cool and I have one, Rx8 is said to handle very well also, I like the wolf in sheeps clothes idea, and I like the fact that I can get one with a dead engine for £400 ish.

I like the engineering project aspect and will do a few trackdays but not much else.

what do you lot think? other criteria to consider?

welcome to the board.

personally, i like the idea of a 20B Rx-8 more than that of a 20B FD, but honestly, you can't lose with either.

mmm....there's certainly an oversupply of broken Rx8's to go at! wont feel so bad cutting one up to put a cage in.
On the other hand, in theory, if I free the 13B up from the '7, that could go in something smaller, given an infinate amount of time and resources....

I think it depends on which body better suits your needs.

In stock form, the RX-8 is heavier and pulls less lateral g's than an FD, so I would not let its supposed handling influence the decision.

Personally, I prefer the FC for street driving.

I say FD all the way! That motor needs to go in the best looking car. Just my 2 cents.

You can stuff a 275 under stock fenders on an 8 with no roll or pull.

WA 20b, wish i had one

I would put it in an fb or fd if speed and handling are the main desire. To me
the RX8 is a close second, a way for a family man to have 4 doors for everyone, and have a fun ride too. I've driven both, and the fd id by far the best handling stock. I have a stock fb and love the way it drives. Power is not my main goal, buy a true sport car drive does it for me. I don't get out on the track, so rarely go over 100. I just want a car that handles the road like a sports car should.
