1986 Mazda RX7 Sport $4250 obo



If you are looking for an inexpensive, safe, reliable track toy, this is your car. I autocrossed the car in 05, 06, and 07, and tracked the car from '05 to now. The car has experienced very few malfunctions, none of which weren't my own fault. The car is very good on tires and brakes - I have a set of RA-1s with 24 track days on them, and they will go for several more weekends (although they are relatively hard now). Brake pads last approximately 6 weekends.



The car made 169 rwhp, 138 lbft with the stock ecu going very rich over 5500 rpms. After tuning the Megasquirt on the dyno, the car made 183 rwhp, 138 lbft.



The history:

Purchased car with 183925 miles with a dead engine in January of '04. I then found an engine, transmission, ECU and harness from an 89 that had approximately 90k miles for sale up north. I rebuilt the 'new' engine with a rotary aviation rebuild kit. In order to make it run, I created a custom wiring harness to adapt the 86 chassis to the 89 ECU and engine harness.



Currently has approximately 197k miles on the odo.



The bad:

The brake bias will lock up the right rear tire. I never got around to installing a bias adjuster, as the HT-10's in the front and HP+ in the rear minimizes the effect. I also have never corner-weighted the car - it was decent the one time I managed to get on scales in '05.





Upgrades:



Car will sell with stock seats and seat belts (not advisable for use with the cage).
