CartechTurbo produced and sold a complete turbo kit for the NA's. The tooling rights to produce these kits were sold to Redline Racing who specializes in Turbo Rotary Sandrails(craaazy!) There located in SouthernCalifornia somewhere and I'm not sure if they're building the kits for RX7's

 

I think that turbocharging an NA is a really bad idea unless you have a convertible. It will be much cheaper and easier to simply sell your car and buy a TII, and then you can add an aftermarket turbo if you like. Once you have a TII, you can get an aftermarket turbo and manifold, custom exhaust, high-flow air filter, aftermarket EMS (and also a boost controller if the EMS does not have this funciton), aftermarket wastegate, aftermarket BOV, performance clutch, high-flow fuel pump, larger fuel injectors, performance radiator, and FMIC. The stock TII drivetrain (except clutch) is good for about 400-450bhp, depending on how you drive your car. The NA drivetrain, on the other hand, is only good for about 220-230bhp. If you insist on converting your NA to a TII, just search this forum as the subjuct comes up at least twice a month.

The size of an aftermarket turbo depends on what kind of performance you want (road race, drag race, street, etc.) and how much money you have. Note that if you want a lot of horsepower, the cost of a turbo is only a fraction of the cost of building up the rest of your car to handle the turbo.

 

I think that either a T-78 or T-88 would work fine.....no, no, no...maybe a T-100 would be better. Yeah, a T-100 would be perfect. CJ

 

A n/a compression ratio is higher then that of other factury turbocharged rx7's. If you turbocharge it you cannot run more than aprox. 6psi without descent reliability and no expensive gadgets(boost timing retard, water injection). You would be better off getting a TII, less money, and work.
