Engine Build Problem
 
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.

more or less.. you definately want the same plug timing.
you can mix s5, cosmo, and rew housings, but the s4's have to stay by themselves.
