Hello Everybody.
I recently purchased my very first RX-7. Its a 1990 non-turbo with about 80k miles on it. Naturally, I'm new to the wonderful world of rotary engines. I don't know a whole lot about rotary engines, so i was wondering, what are some good ways to raise the horsepower and torque (especially low end). I also plan to add a turbo. Should i do any internal mods to increase the overall integrity of the engine first. Any info, input, comments, links,etc. would be very much appreciated.

Try all the Bolt-on parts first, these little motors do not make much torque in non-turbo form. From what i have heard, the mazdatrix dual exhaust will greatly increase torque, it costs a pretty penny though.

It will bring you years of joy if you treat it right.
Like the others said full header back exhaust is a good idea and I would get a clutch and flywheel. this should put you in the low 15s I think. Turboing an NA isnt a very good idea unless you like spending money.

I know you have to drop the compression if you add a turbo. In a piston engine you just add a thicker head gasket. How would i lower the compression in my RX-7? I owuld have to buy a new howsing would i?
