Engine Problems
 

OK.... first thankyou in advance.

I have a 1994 Rx7 with a single turbo conversion.

I went to go FINALLY have my RX7 tuned and the tuner told me that my motor had a S6 housing on the front and a S4 housing on the rear. He told me that my motor is UNtunable, because there is a timing variance between the spark plug position of a S4 vs. a S6. (apprx 8 degrees)

Is this true?

Am I going to have the tear out my whole install to rebiuld my motor with two S6 housings??

The setup I have is able to push 500Hp+, we were going to tune it to approx 440hp.

Thank you,

Please verify this and please send me your comments.
