Naw, just use it as a year round pickup. The stock 80HP engine isnt as fun, and I figured a rotary is different, and relatively easy to swap into the truk, plus a learning experience.
It would cost $500 or more to convert my truck to EFI from the electronic carb, which would include redoing the engine bay wiring harness, so this swap is only 2-3X more money, and alot more fun lol.
This thing would have 20-40 more HP than my Fiero, 40+ more lb/ft of torque, and my truck is a hundred lbs or so lighter than my Fiero. Nice thing about this motor is that to get the equivalent of a cam regrind, all you need is a dremel
and some time, no money required, except for power to run the dremel, and the dremel bits.
Should be able to be reliable (as far as the swap goes), because an RX7 tranny pretty much bolts in, just at most, move the shifter (which the trannies have 2 positions for), and make an engine mount. Or if I want, I can unbolt the stock bellhousing, and bolt on an RX7 bellhousing to my stock tranny, but my tranny isnt made for the power of that motor, and already has a bad synchro in 2 and 3, and whines alittle in 5th and neutral. The rear diff is swappable too, so I can pretty much bolt in an entire RX7 running gear into my truck.
My rear end ratio in the truck right now is 3.9:1, and that is the tallest (?) gears I can get. They make gears for this diff all the way down to something like 5.4:1 (5.somethign :1).
I am going to lower it this spring, it should cost as much as rear lowering blocks, the front suspension is torsion bar, and to lower the front, I re-index the torsion bars, they have a splined shaft in the a-arms, 1 spline is about 2-3" drop, but with the same spring rate as stock
