Gutted the majority of the car yesterday. Removed some bs amp and yards upon yards of wiring that was installed. probably saved like 20 pounds just like that. Leaving only the original, necessary components. Got the trunk carpet, amber markers and turn signals. Found a spoiler and the board for the spare on here, so waiting on that. Installed the 18s on the car with the fresher rubber, the 15s are for sale:

As for the engine issue, my mechanic basically ripped out the entire engine harness and threw it out. Something was happening with the car that it would drop down to 8 volts. Hit up wiring specialities to get the needed harnesses and subharnesses. Should have them tomorrow and will install immediately. Fingers are definitely permanently crossed. Need to have this running asap.
