Well, she's never been dynoed so it's all ass-o-meter, but driving it compared to other cars we estimate around 240-260hp. I'm not sure about torque. Rotaries aren't the torquiest beasts known to man. Boost comes on around 3, and from there it's pretty strong. I've only had the car a year, so right now when I have time and money I'm just going through her and tidying things up. The car was a wiring nightmare, and a lot of the soft interior bits need some TLC. She has a full Racing Beat exhaust (that damn exhaust is 1,600 dollars on it's own so I'm glad the PO coughed up the money for that) that really helps spool, and a 9 lb. HKS flywheel to help things spin up much faster. The biggest issue right now is that under heavy(I say heavy, but I mean about 10 lbs.) boost she breaks up a little, and can't get a clean pull. We're talking to some stand alone ECU guys (DIY Megasquirt) about using her as a test bed to create an aftermarket ECU for a Turbo II. There's nothing out there like that unless you build it from scratch yourself. Right now she's using a Gameboy Advance to run a rudimentary boost controller program, but that's not ideal.

Once that's done, I plan to upgrade from the S4 to the S5 turbo, and switch the stock Hitachi turbo housing to a Greddy housing. Hitachi is basically a poor man's Greddy and switching the housing out is supposed to be straightforward. The nice thing about a rotary is that you don't need to upgrade to forged internals, so you just change the shape of your ports, get a good engine management system to control AFRs, spark, blah blah blah, and we should see 400hp and similar torque with just the stock s5 turbo and slightly better housing.

All this is long-term. I have school, racing, and plenty of other projects. She'll get there though. She gets some love about once a week.

That red hood in the background is a customer's Miata. It'll be putting down 375-400 rwhp, and going after z06s or Carrera Turbos here soon. We're pretty excited about that.
