Frankenstein RX-7 Race Car Build

I've been all over the place with this car. At one point I thought it could be a street car, but eventually I caved and committed to fully gutting it for track duty.

As I received it, it was a $free 1982 RX-7 rear ended with irreparable unibody damage and lots of go-fast parts. I bought a roller to swap the parts over, then discovered the roller's transmission tunnel was torn open from some explosion. I welded in a new transmission tunnel and swapped literally every part, nut and bolt from the crashed car to the shell that I could.

For your enjoyment, here is an old narrated imgur album of some of the progress so far, I will try to update this and/or this thread with future progress:

It's now at a real racing garage, and the goals at the moment are to remove the windshield, cage it, lexan windshield, paint the interior with rust-oleum epoxy white, clean up (minimize) the wiring, and race it as a track day car.

Because of the following mods it's illegal in most SCCA classes:
Weber 48 13B Half-bridgeport
FC Turbo 2 Transmission
ReSpeed custom front subframe (incl. Mustang steering rack&pinion)

Some day, I may remove those illegal mods and run SCCA improved touring, but having driven other cars with recirculating ball steering I'm not too eager to forego the rack&pinion setup.

Thank you to all of those who have provided advice and assistance thusfar!

Super nice fab work.

Your car is legal in SCCA STU with that engine at 2548lbs (2600lbs - 2% for no ABS brakes) with a stock subframe/suspension.

I've never driven a car with the RE Speed sub frame but I have allot race miles with the stock stuff. The stock stuff works good enough and besides you steer FBs with the rear tires as much as you do the fronts.

Looking forward to seeing your build unfold

Just to clarify the inline 5 & 6 rotor engines have a support in the middle. Every individual rotor has to have a stationary bearing to work against while the rotor makes combustion. The limitation on the inline rotaries is in the lubrication; cause how are you gonna get enough oil down a long shaft without oil pressure being too high in the rear of the engine.



Stay with the RH sunrise red. Keep it original
