mazda rx-8 sr20det swap

It's come time to sell my beloved Mazda RX-8. It's a 2004 with a 1992 SR20DET Redtop engine swap in it. Car is currently tuned to 15 psi on 93 octane gas. It's making around 300-350 hp. The car runs and drives!! It's in need of a new tune though to run more efficiently. The new tune should have the car running 22-24 psi on E-85 to make around 450-480 hp. The engine itself has only around 3000 miles on it. It was completely rebuilt using aftermarket parts. I have put a lot of time and money into this vehicle and am only asking a fraction of the price. The car does not have radio (common problem with this year of RX-8's), A/C, wiper blades, or power steering but can be applied easily. The tach and speedo also do not work, but can be fixed as well. Right now the engine is running off a Megasquirt ECU. If you want the dash to work, you will have to wire up the stock RX-8 ECU as a standalone. It is currently plastidipped the silver color, with it's original color being red. I am being fair with the price. Over 21,000 dollars have been put into this car and it hauls ass. It's 98% complete and I'm out of cash. So instead of letting it sit in my driveway, I'm putting it up for sale. FEEL FREE TO MESSAGE ME WITH OTHER QUESTIONS OR TO REQUEST VIDEOS.
