what do you know your right. lol Yea there's a automatic motor and the manual motor. One is higher compression than the other. that's funny

10:1 @ 12psi thats nuts. Your going to fry your motor if you don't watch it. lol
I would definitly suggest that you go with the lower compression pistons. you dont need the bottom end or the block, just the pistons I dont think there are really any differance is the block or rods.

Now that YOU mention it, there are 3 versions. The ones i mentioned above are for manual cars, i dunno the specs on the a/t ones though.

As for CP on my car, you know the real thing about it is intake temps. The colder you can make them, the more boost you can run. I should say, im not at 12psi on my 99 yet, still at 7-8.5psi.... once i do the 60mm s/c pulley , it'll go to 11-12 psi (will add intercooler, injectors and SAFC too). I was running 10-11psi on my 96 though with no detonation at all. I was even runnign 14* advance timing. The key was big injectors annnnnnd intake temps. Between all the heatshielding to keep exhaust heat away, the air inlets (turn signal intakes on Miatas) and the intercooler, the coolant lines removed from the t/b, 160* t-stat and a huge KOYO radiator (55mm)... i had no problems with heat.... hell my intake manifold never got much warmer then ambient temps when it wa warm outside and when it got cold (for the short time i had the car while it was cool out) i would say intake temps at the manifold were no more then 10* max more then ambient.

Somone once told me that a Jackson Racing s/c will never blow more then 10psi..... hell the s/c on a Cooper S is the same M45 blower and its pushing 11psi stock on the S.

But yeah, there are 3 versions of the "BP" 1.8L in the Miatas. Whats the motor code for the 2.0L Protoge fro mthe early/mid 90's?? It was a DOHC engine.....looks like this... (yes, thats my old Miata).I figured out the valvecovers were interchangable with minor mods... looks much better then stock Miata.
