Heavily modified to support GT4088 Turbo.

1986 Mazda RX-7 Additional Info:

1986 Mazda RX7 Base “Rexanne”, heavily modified and dyno tested in 2022 to produce 325 rwhp and 290 ft-lbs torque on a base tune (refined fuel and ignition tuning could net over 400 hp). Body had 270,000 km at the beginning of the project. Odo in Racepak shows 1,302 km since install and engine build. Always meticulously maintained and garage stored. Fluids all replaced during build (diff, brake, coolant, oil). Fresh coolant fall 2022. Oil has been changed 3 times since rebuild (every spring). Rexy has been a wonderful project, and I’ve been enjoying the finished results over the past couple years. Sadly it is time for me to move on to more family friendly hobbies.
