My bro's Mazda RX-7 TII for Sale
The car will make over 400rwhp on pump gas at 13-15psi. C16 and 25 psi will make close to 500 no problem. Smaller turbos on the same motor have made 490 @ 22psi. Take all of that into consideration with a car that weights in just shy of 2800lbs, then you know you have a fast street car.
