Ya, I'd rather just make it easy and put those 2 turbos on. Maintenance is pretty shitty on RX-7's as you said. To keep it running solid you should replace the oil like every 2,000 miles, get a fuel management system, I may get a 3 or 4 rotor engine in place of the stock one, I'd probably kill myself with that though cause it'd be too damn fast.
