I love my 1987 RX-7 GXL and I have been considering getting my engine rebuilt, new full RB exhaust system, and a full fuel system. I also realized that this will not give me all of the horsepower I am wanting. I don't know... maybe it would. I want my car to have about 200-250 HP. I figured I would probably have to get a TII engine instead and modify it. I guess I am just asking if I could get a n/a to be a 200+HP beast. Would it just be cheaper to get a TII engine for my car and have to go through the "wiring hell"? I don't know... I just want to know your opinions.

 

Its cheaper and easier to get a TII than it is to make an NA reach 200whp.

 

200 whp is about the limit for a streetable port non-turbo engine. Doing that requires a fresh rebuild (with new housings), a large street port, exhaust porting and probably a standalone. If you want that kind of power you are better off going turbo.

 

cheaper to sell the NA and get a TII.

 

Alright, thanks a lot guys... How much you think I could get for a non-turbo 13B with like... 123k miles on it?

Oh, and where do they sell good TII engines?... are the ones on Ebay legit?
