Hello all you rotary nutters!

Interesting stuff. So as long as it has a manual gearbox, it should have the dual oil coolers? I'll have to visually check when I start test driving cars after the holidays. Sounds like an '05 GS with cloth seats, no sunroof, and a manual gearbox will have the dual coolers and should therefore be a good starting point. Will most likely end up with an '05 because there's a ton of them for sale around here right now for $12-13k with nice low mileage, whereas the '04s all seem to have quite a bit more miles. It's not exactly prime time to sell a car like this in Toronto, but there's still a surprisingly good selection of '04 and '05 to choose from. I'll let you all know how it goes!

Phil, I've gotta say, I am intrigued by the idea of doing a Rotrex blower on the 8, mainly because I installed a Rotrex on my EG Civic race car and it made a ton of power (went from 240whp to 412whp). Would be interesting to see how the Rotrex works on a Renesis by comparison, and if you read my story about the Rotrex install you'll see there's a lot to like about it as a forced induction approach. Low heat, low engine loading, no chance of an overboosting booboo, etc. Anyway, feel free to check out the install and dyno test story here:

Does anyone make a Rotrex-based supercharger kit for the 8, or will I have to fabricate my own mounting bracket?

Welcome to the site, I look forward to see any rotary powered projects. Congrats on working for a great mag.

No it will have to be custom made. On rx8club.com there is a guy from Australia that did a rotrex sc build on his 8. Here is the thread: http://www.rx8club.com/showthread.ph...ghlight=rotrex

Not sure if it has much useful info in it, I just glanced at it briefly. But he would be a good person to get in touch with about the Rotrex SC on an 8.

Cool, thanks for the link 05rex8. I'll give it a good read.

I did a Google search and found that Knight Sports makes a Rotrex-based supercharger kit for the 8, but I think I'd likely build my own kit after the experience I've gained supercharging my Honda with a Rotrex C38-61.
