I have had a project in the shop for the last year or so. I had a client with a 1984 Mazda B2000. Beater truck, 100 and some odd thousand miles. He came to me and said he wanted a Rotary in it. Bought an 1980 RX7 and off we went. Engines came out of both. Frame on the truck had to have stock mounts cut off and custom mounts made for the rotary. Modified the cross member for the rotary transmission. Had to cut up the header from the RX7 and make it fit. Custom aluminum radiator was installed with a fan. Had to cut the water neck off the water pump housing and thermostat to get what I wanted. Then he threw a curve ball and said, "Lets do a four barrel intake and fuel injection." I suggested we do the two barrel unit and parts were ordered. I used a circle track racing adapter that allowed the spacer to be slid into a better alignment and I ported the four port intake to make it all fit. He wanted the Oil Metering Pump that runs off the engine to function but wanted an oil tank to feed two stroke oil and not engine oil the unit uses normally. So I dismantled an OMP and figured out how it functioned and found a dimple cast into the housing that works as a feed port. Holes were drilled and a fitting was made. Tank was found (lawn mower coolant tank) and mounted, hoses were run. I found the gravity feed was just letting oil seep into the engine from the aluminum shaft housing that had zero seal. Motion Industries had a small seal that would work so that was purchased and the housing was machined for the seal. That stopped the oil loss. Now the injection was just not running. It would start and stall. I tried everything I could think of. I then added a fuel pressure gauge and found the built in regulator was garbage. 120 psi on a 56 psi system. Added and Aeromotive regulator to the return side and it fired right up on a 100 cubic inch tune.
I have now been driving it around for a couple days now. Had an issue with stall coming to a light if you clutch it. Adjusted the setting to catch that and it is really a fun truck. I think it could uses more rear end gear. It pulls away kind of slow and has a really long first gear. I can run 60 mph in fourth and be at 2250 rpm. This thing would rip with some gear. My pictures are all to big or too many thingys to load. I will try and get some on here later.

Kinf of cool but this is not the kind of thing people usually hire done is it?

This guy does. He is a really cool guy that just loves odd stuff and can afford to have it built.

Now an LS going into the RX7?

Nice collection in the background as well.

That would be my thought but the plan was an RX8 engine in the RX7. That has changed and we are probably selling the RX8 and the RX7 body. So it may get an LS but not by me. Unless the new owner hires my to do it.
