I have recently bought a 1981 series 2 RX7 and I was just wondering how much power I can get out of it and still keep it streetable. A turbo is out of the question at the moment cause the insurance cost would go through the roof (i'm only 18). It doesn't matter how much it costs so go a bit wild....

 

You can still put a turbo, just don't tell the insurance company that you've got one. At least they never check my car, but i don't have the money for the turbo.

Otherwise if the money is out of question go with a small Peripheral port. It is still going to be streetable but not as nearly streetable as it is now. Especially if you have all the goodies with it. It really depends on how it is done also. If not peripheral port you could always do a bridgeport.
