heh, check out the RB25 cam angle sensor. Ive always wanted to do a 4 rotor FD. The Scoot 2.4L 12A based 4 rotor is a rad car. Only problem is a 4 rotor is like a 700-800lb engine. Oh and yea Mazda never sold 4 rotor engines to the public. Just 3 rotor. There were very few 4 rotor engines at all that made it into non-works team Mazda racecars. I think the best U.S. source of info on those motors would be Jim Downing from DowningAtlanta who has raced rotary LM and GT cars for many many years now.

Also rotary engines actually do make good torque, at least for their displacement if you consider a 13B to really be 1.3L, (its really more like 2.6), but they dont have the torque down low, they have great high end torque which allows them to make sick hp numbers up in revs where most engines would start to wheeze out.

I was wondering about the CAS on the engine, never seen one like it. Thanks for the info.

It is being rebuilt at the moment. But at the moment it has done a 10.5 sec on stock rims with slicks, stock suspension, stock body, stock 5spd gearbox with heavy duty clutch/lightened flywheel, just had a carbon fibre bonnet, stock brakes, just stripped out. But now it has a air shifter gearbox and skyline axels but it hasn't been back to the strip yet.
