Okay so this is my latest find. This is a 74 with a 13b Rotary motor that was built by Racing Beat in CA. Looks like they were in Anneheim. Not sure if they are still around. Guy bought it in similar condition to selling it. When he bought it the motor had overheated. He took it to Racing beat & had it completely rebuilt. Said it was pushing 220hp but only got 5mpg. I know rotary's came in rx-7's for the most part. Thats about the extent of my knowledge of the rotary. The guy has had this sitting in his garage since 99 when it overheated on him. He said it won't run but will turn over. I'll get more detailed pics of the fron radiator setup with oil cooler. Take a look at the motor pics. Defintely looks to have been a pretty hot motor. Kind of figuring to go Suby with the TDI conversion as a possibility.
Anyone looking for a project I have like 3 cars I will be getting rid of (IMG:style_emoticons/default/biggrin.gif) . Anyway take alook at the pics & let me know what you think. Paint code is l64k which is a forest green. Obviously it was repainted some shade of red/orange Attached image(s)

Just a heads up, one of the bigger problems we see with the rotorys is their apex seals ( that is a rotory's version of piston rings). The 13b has 2mm seals where the 12a has 3mm seals, but bigger doesn't mean better. It is all about the material the apex seals are made of. Another thing to look out for is the ports. The 12a has the intake ports on the top, where the 13b has its intake ports on the side. This means the 13b has intake exhaust port overlap. This overlap means that they have to run the engine pig rich to keep it idling. On the renesis engine ( the rx-8's engine) the engineers moved the ports back to the top. If you had the money to built a renesis, that would be the way to go. If anyone has any questions ask me, I have been messing with these engines for almost 12 years. If I don't know something, I know where to find it.
