Man, that is one hella cool setup! We've thought of building a rally car using my buddy's '84 626 and a 13BT, but never got around to it. With the 13B PP motor...your looking at around 300HP depending on what your exhaust setup is, and your other mods, etc...you will be able to walk all over most stangs, camaros, and most other NA rx7s, lol...

Racing Beat has PP housings for turbo applications. I think I wet myself.

Hey Herman, Wooffinn here. Man ex rally driver here!! I'd say that performance will be some where between yeebloodyhah and the point of no return for your underwear!! About 10 years ago[showing my age] a friend and I had an RX-2 group n rally car with a 13b na bridgeport. insanely quick with no brakes!! https://www.nopistons.com/forums/pub...#>/biggrin.png We only really had two main probs, the rear control arms snapped on a VERY regualr basis and wheel base and track are too close to being the same measurement.Basically I spent most of the time correcting the oversteer but it was great fun never the less!!

I got a ride for a season in the navigator's seat in one of those group A 4wd 323's but as you would expect, it stuck like S#$# to a blanket. Certianly sound's like fun, need a navigator???

Herman: Where are you from ?

I plan on building a Peripheral 12A myself.
