Sorry if this is a double post, I searched and read this entire forum.

With that said, on to my question. I'm simply wondering (cost aside-like I'd have the money to do it anyways, lol) is it possible to put the 787B (26b 4-rotor) motor into an FC? I have an '88 GXL and was thinking that since it looks like the largest of all three of the generations of RX-7's, that a 26B would fit. I read all about 20B conversions, but it would be so awesome if I could throw in a 26B. If anyone knows, please post. Also, if I'm wrong about the 2nd Gen being the largest model (engine compartment wise, as well) then let me know that too, thnx.

*edit* one other thing. Would the power gains from a turbo 26B be real significant over that from a 20BT? If power gain isn't that much, I can go ahead and put back for a 20B swap (which will probly be the case anyways).

 

your not going to find that engine anywhere, mazda doesnt sell it, you could have it custom made, the shaft is only $40,000 last time checked. a 26b made 700hp n/a when pref ported.

yikes. 20B it is. That's awesome hp for n/a, btw.

 

700HP N/A !?!?! oh dear god...

imagine what a pair of T-88"S would do to that thing *DROOOOL*

 

I have some 4-rotor links in the 20B FAQ and Links page:

You can get custom shafts for a reasonable (relatively speaking) price through Australia and NZ.

A professional 20B conversion is about $35,000, and that's with a rebuilt engine.
