Honestly I would find a nice 86-91 body style, get a turbo rotary (13bt) get it rebuilt and put down some good numbers. $800 for the stock turbo on those cars to a hybrid rebuild; capable of putting down 350rwhp at 15psi on a stock port engine plus it bolts to your stock exhaust manifold (save you $350). If you guys don't believe me check out BNR turbos at rx7store. You could have a very fast car (low 12's, high 11's) for $5-$7,000.
