RX8 Motor Swap, Anyone Done It, or Thought about it? Options

[cdmcse]

Is anyone familiar with the RX-8 Motor? I was considering it for a swap.

Anyone know if the bolt pattern is the same as older rotary motors?

It seems like it would be fun engine in the 914.

I do believe the transmission bolt pattern is the same for all the rotary engines. 12A or 13B. So a Kennedy kit should work with the newer renesis 13B. A renesis engine swap would be really fun car, but it would lose in some HP shoot outs against the V8 or turbo Subie, but you can rev to 8500+ and that's ALOT of fun. The renesis engine is mazda's attempt at making a "fuel efficient" clean burning rotary. I've heard that the older 13Bs when modified are capable of higher HP numbers than the renesis, but that was early on, I'm not sure about now.

Exhaust for a non renesis 13B will need to be heavy duty,, but can be much lighter for a renesis due to exhaust port design. Not much if any power can be had by adding a header to the renesis, so the stock exhaust manifold will simplify the exhaust plumbing.


For the easiest swap with a rotary, you will need a GSL-SE front cover (because the engine mounts bolt to this) and any early 13B oil pan. You can then use some angle iron and make a very simple engine mount with the stock bar. It's WAY EASIER than many subie mounts I've seen.

Try to use the whole renesis intake and ignition if you can get it,, it's very efficient.

I love my rotary engine, but in light of all power a Subie makes,,,, I want a ride in a turbo subie so I can get a feel. My 13B streetport makes 220+ HP

Ask me any questions you want about rotary stuff. (IMG:style_emoticons/default/drunk.gif)
