rotary car build

[Paaull]

I'm building a 4wd mud buggy based on a Suzuki Sierra chassis that I want to repower with a twin cam efi 4cyl or rotary. Not overly fussed on the engine as most can be worked easily. So thought I would ask about the trans so I know which rwd half cut to buy.

You can go with the NA manual trans, out of any year, but I don't know of any way to attach the transfer case. You would have to divorce it.

The Auto trans in the RX7 is a common trans (I think it was used in Subbies, Nissans and Ford Rangers). It is possible that you may be able to get a transfer case setup to fit. I have never seen it done. The Auto trans is weak, they don't hold up well to a stock NA rotary. Mine is smoking after 5 0-60 runs.

You can buy adapters from a rotary to a Volkswagen Beetle (air-cooled) trans, a Ford Trans and a Chevy Trans from Kennedy Engineering. I have also seen mounting adapters made to use the rotary auto-trans bellhousing to contain a clutch and attach to the front of a transmission.

This thread should probably be moved elsewhere.

welcome to the board. :)

if you do decide on the rotary engine for your project, i guess my first question would be, does the Sierra transmission have a removable bell housing? if so, you could probably get a Turbo II transmission and see if you could find a way to adapt the bell housing to fit. i know it's probably easier said than done though. the only other thought that comes readily to my mind is use the transmission from a B-series truck because i know people have put rotaries in them many times over.

obviously, you're likely looking at custom driveshafts either way.

good luck.
