I have a stock 93 RX-7 TT and i wana bolt on the Efini turbos that are on the 99-02 RX-7s sometime soon. ( http://rx7.com/store/rx7/fdturbo.html#efinitwins ) Im ordering my exhaust next week sometime. What would someone reccomend i do cuz i know that would be pretty hard on my motor just to have that done to it. I know ide probably need a new ecu and all but what other things would someone reccomend i do so that it would be alot easier on my motor.

Thanx

 

depending on your goals the efinis just may not be worth the cost. my best friend owns a 93 with the 99 efinis on it. when he got steve kahn to tune it he had a power fc, stock cat, peter farrel exhaust, peter farrel clutch, stock fuel, and m2 airbox. he maxed out his injectors at 6200 rpm and made 280rwhp, and 270ft/lbs. so just secondary fuel injectors, and a midpipe would net him about another 40-75rwhp depending on how aggresive the tune.. but then after that there isn't much more you can do with twins.. might as well switch to single and get rid of the rats nest (all those damn vacum lines). would you be going non sequential or sequential? what boost?

 

i agree with the above dude single turbo even tho u know u could brag sweet jdm goodness with the enfini's
