S4 TII to S5 N/A chassis, feasible?
*Sigh*
Well boys and girls I can't seem to find anything specific on the situation.
I have two rx-7's and a S4 TII swap....Here's the dilemma.
I want to rebuild the TII using the S4 N/A rotors to yield a positive bump in compression and once the the engine is done I want to swap it my S5.
Being an S4 TII would it be to much trouble to swap it in my S5? I understand the difference in sensors, wiring etc. but don't understand the complication of doing such a procedure.
The reason I want the 89 rx7 to have a turboed heart is simply because I like it better that the 87.
Now the 87 has no compression in he rear rotor and is of same generation as the TII swap, making it an ideal candidate for said swap.
The 89 runs great, just passed emissions with the help of tons of elbow grease and is fine as it is.
Questions come down to; Would you do the S4 to S5 swap for turbo sake?
Any thoughts on higher compression N/A rotors in a Tii BLock?

The proposed Frankenmotor/swap will net you maybe 50hp, which seems like a poor return on the money and effort required.

Yeah it passed with flying colors after redoing the vacuum lines and the cats
I was expecting it to fail, but I wanted to see what the numbers looked like.
Well, I think what I'll do is leave the S5 alone and do some basic mods o he suspension and keep it clean.
The S4 chassis will get the TII since it's the same gen.
I am hoping that the bump in compression from 8.5:1 (Stock S4 TII rotors) to 9.4:1 (Stock N/A rotors) Will not only give me more horsepower and torque, but will let the turbo spool up quicker. Only downside is it is more likely to pre-ignite or ping.
