Paid too much for this, only to find out it was actually a non-turbo Rx7 with the turbo engine and transmission swapped in. The stock, weak, na rear-end was still in, and had been "modified" to work with the turbo driveshaft. It also had the weaker, non-turbo braking system.
I have since fixed/upgraded most of what was wrong, though I'm haveing continuing issues with the engine. I rebuilt it once after the coolant seals started leaking, and now I have to rebuild it again due to tuning problems which left the rear rotor with no compression. As you can see in the dyno charts on the picture page, for a while I was running very lean. I managed to tune most of this out with the safc, but I could only add so much fuel before the afm reading was maxed out. I eventually found out this was due to a bad fuel pump rewire, and once fixed, the car seemed to run normally. This time however, I tuned the safc without a wideband, and my engine died in the middle of New Hampshire.
