First off, sorry to hear about your miata. Even though the miata is lacking in the horse power dept, its light weight and rwd configuration make it a blast around corners.

I suggest staying away from fwd cars, as you seem to enjoy driving around corners. Try a 2nd gen rx7 turbo, although rotary engines are not for everyone... as you have to learn all it's quirks. Another option would be buying a turbo 240sx, you should be able to easily find one used as it seems everyone who buys one, turbos them.
