RX-8 20B 3-Rotor Conversion W/ Spare 20B - Needs Rebuild

Up for sale is a 2004 3-Rotor Conversion RX-8 in Lightning Yellow. 47.5K miles on the chassis. I have a clean and clear title in hand. The front fenders, hood and front bumper were painted when the Mazdaspeed bumper was installed for a color match. A clear bra was then installed at Xpel - the leading edge of the hood and fenders were also done. Also included is a spare chrome wheel and the Mazda factory shop manual and car cover. All the factory gauges work as well as the factory steering wheel controls for the stereo.

I purchased the car with an (undisclosed) A-series weak engine and when I discovered this, I purchased a C-series core with brand new housings. The engine was rebuilt 2500 miles ago. I still have the original engine and the 20B housings (re-useable) from the core engine. I have run Idemitsu rotary premix 1-1.5oz. per gallon for break-in. Unfortunately, during dyno-tuning the fuel pump failed, causing the engine to lean out and as a consequence, the apex seals sagged. The engine car is tuned for 12psi and still runs, but the engine requires another rebuild (low compression). It's a sharp car and gets compliments everywhere, but after all the time and expense I'd like to move on. I'm willing to sell the car alone or with the extra engine. Asking $25,000 with both engines, $21500 without the spare. The 2nd disassembled motor needs one more rotor and full rebuild kit to use. If you have any questions, feel free. Serious inquiries only please. No test drives unless cash is available. Thank you for your interest. Below is the list of parts:

It was formerly Tito Ramos’ 3-rotor RX8 from Texas and I think it’s in Indiana now, but the OP needs to confirm where it will need to be seen and picked up from.

Wannawankel; you reply copied the whole thing just to post “best of luck”, really?

Yes, the car is in northern Indiana - Middlebury to be exact. It's about 30 miles east of South Bend.

With the weather finally warming up, I was able to get video of a cold start, warm up and idle two days ago. Feel free to contact me if you would like to see it.

Me too! A 20B RX-8 is a dream build, especially in NA trim for me. Curious to see what they do with it.
