I have a 1990 GTU with 106,000 miles on it. Its in perfect shape runs awesome everything. My only complaint is it minor lack of power, its a quick car but i would like it to be quicker. My goal is to be a taurus SHO, and i dont know if its feasable but ill try. So guys, i was thinking headers back exhaust, intake, and idk what else. What type of performance and HP gains should i get from the intake and exhaust? And what other mods should i look at? Thanks a lot.

 

not what they claim.........I have heard that true duals are the best for power gains but they are expensive......SHOs are quickand not to be taken too lightly, and the rare 5 speed is pretty damn quick. clutch flywheel, intake exhaust, S-AFC(with a dyno tune) you might have a problem with the 5th and 6th ports so you will need to wire them open......I can't think of anything else at themoment.....be back later.

 

lol, sry but whats s-afc mean? and how do i wire the ports open? im new to the rx7 thing- the engine hooked me lol. And i know SHO's are quick, my best friend has one with a 5 speed.

 

Don't wire them open, but rather make sure they are working.

Use the search function.

aaroncake has a write up on how to test and clean the 5th and 6th ports.
