First, I don't know anything about rotary's. I'm a V-8 guy. I have a few big blocks sitting around, so I started a project. I bought an 80 RX-7, 12a, it ran, but badly. I got it to do the conversion from the rotary, to a big block (440, .060 over, forged crank, 6-pack rods, Weiand Tunnel Ram, with twin 780cfm Holley's.) It's a tight fit, but looking at some of the info on here, the rotary seems like it could be a lot of fun. I'm no stranger to boost, and if I kept the 12a, I would certainly need to turbo charge it. But, being that it's not a pushrod motor, it's going to take a little relearning on my part.



What would it take to make an honest 300+ rwhp out of the 12a. Planning a blow thru setup on a holley carb.



Does a rotary suffer from the same sort of detonation problems as a piston motor? more likely, less likely. What are the limits of boost when using 93 octane?



Who has experimented with water injection?

www.rotaryshack.com robert has made 720bhp out of his 12 turbo. 300bhp is acheivable.. And more fun than any 300hp piston would be!
