This is the first car I ever owned, I paid way too much for it and it had more than a few hidden problems. To make it worse, I eventually found out it was a non-turbo Rx7 with only the turbo engine and transmission swapped in. The stock rear-end from the non-turbo car was still in it and had been sloppily re-drilled to work with the turbo driveshaft. To top it off the paint was terrible thanks to a bad respray.
In between short stretches of driving it and long stretches of parking it, I’ve attempted to fix most of what was wrong and complete the conversion to the to turbo model of the car. I rebuilt the engine once after the coolant seals started leaking and replaced it a second time due to tuning problems which left the rear rotor with no compression.
The dyno charts show the story of the 2nd engine destruction, it was running very lean at the time. I managed to enrich it somewhat with an Apexi S-AFC, but I could only add so much fuel before the afm reading was maxed out. I eventually found out the lean condition 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.
I eventually put a junkyard engine in it get it going, but never drove it much as some of my more questionable modifications caught up with me. Right now it’s stored outside in Nh, slowly deteriorating until I have time to fix it up.
