yeah guys my bad it was a typo my 84 rx-7 12a thanks for the advice i know im gonna need heavy mods to run 11's but i was thinking my cuz has an 89 mazda m6 gt and his **** runs 12's on slicks 18 psi and a few other **** but nothing to pricy and he is looking for more power he wants to hit 10's so know he is getting a racing engine that can handle up to 30psi!!! i told him he is doing the impossible but he really know's his **** though.that made me think i can get that too with my 12a but i wanna run 11's first im looking for a turbo manifold so if you guys can help me find one, i will appretiate it thanks.

 

mr.12a you need to find a mr.13b turbo exaust manifold and than use a four vylnder turbo header and you should fir with some fab with the exaust manifold but it can be done

 

dude, welcome to the forum ... but please research this first.

i'd hate to see you added to the list of people that start posting "Rx-7s are unrelaible ..."-threads because you want too much for too little.

anyway ... there was a turbocharged 12A that ran 10s, so your 11s are more than possible with the right amount of time, money and attention to tuning details. right off the bat, if you want to jump in feet-first, then i'd say get an RB 12A exhaust flange, some thick mild steel piping and a T4 flange, and make your own manifold. then go from there ...
