get in touch with Roger. he will have all the conversion parts you need. mounts, dry sump, water rail, etc.
use your standard crossmember and go to a wrecker to get an engine. he has conversion parts for an rx7 5 speed, but there are other options for gearbox's.
and get ready to start dishing out the cash. depending how crazy you want to get with tuning.
