I received an e-mail one day from a friend of mine offering a free RX7. Free car you say, what a deal. Well rx7 enthusiasts don’t always have this reaction. These cars are notorious for having blown engines (a design “quirk” of the wankel rotary engine) and being money pits. Many cars have popped their motors and have been left to rot in black berry bushes. This leads to rust, mold, and rodents. A free rx7 always ends up costing you something.
For our purposes these kinds of typical problems wouldn’t really matter that much. We were going to strip everything off. Many of the creature comfort systems (like uhh, the windows) would be removed. We needed a big hunk of metal to put an engine in and connect to some wheels.
I took my friend up on his offer and when to checkout what would undoubtedly become my second job for the next year. This is what I was greeted with.



Way better than what I was expecting. Look, the paint is even shiny. The car was 100% complete. Clean title. Keys. Spare snow tires (it already had snow tires on it, lol)! 130k on the clock.
Here is the story that I got. A woman owned this car and loved it. She was either the first or second owner, I can’t remember. After over a decade of service, it had developed some kind of serious problem. At that point (some time in 2002) she purchased a nice Toyota and this car was parked. There is stayed under a tree. There is good evidence (broken windshield, half the car literally covered in small dings) that some punk kid had used it has his rock throwing target (is this what red necks do before they are old enough for their own “shootin’ car”?). Earlier this year, my friend was offered this car if he would come pick it up (Grants Pass, OR if I remember correctly). He confirmed it was a 5 lug (5 bolts on the wheel, the more desirable form of this car) and brought it back.

(Pictured here, Rob, one of our teams principals, aiding with the loading of the vehicle).
It was then brought back to yet another tree to sit under. Three weeks later we started work. The mean goal was to try to figure out what was wrong. Was the engine completely shot? Could we get it to start? What are the major areas of repair we would have to deal with?

RX7′s have crazy spark plugs. Turns out this car uses the exact same plugs as my 93 twin turbo. I grabbed a set of used plugs from by car and put them in. Pictured are what came out of the car. Relatively uniform, thats a good sign. We also created a gheto siphon system with a garden hose to suck some of the presumably bad (sitting for 7 years) gas. It was mt dew colored. Nasty.
With fresh plugs and gas we hooked it up to some jumper cables and gave it a shot. It would turn over but no combustion. A plug was removed and observed while we cranked. We were definately getting spark so are problem is probably fuel. To confirm the diagnosis we opened up the air box (slightly damaged, we will need to do something about that. This is a easy place to modify for simplicity and power anyway) and sprayed starter fluid (to act as a fuel source) right in. After a couple tries we were able to get some combustion but only as long as we were spraying fuel in. We weren’t getting fuel delivery. The fuel filter was try and there was no pressure in the lines.
Fuel pump. We checked wiring and we were definitely seeing some voltage. Something had to be wrong with the pump.

See the rubber insulator mounting at the bottom of the pump? That had been dissolved to the point that it acted like silly putty. When turned over a nasty brown fluid came out the top. This pump was shot. Rob had a walbro 255 sitting around (for a 240sx but we could make it fit for testing). I wired it up and got it in the tank.

She fired right up and purred. No overheating (at idle). No strange noises. Would rev all the way to red line.
Known issues at this time:
Alternator – Belt was broken and sitting in the back hatch. Would not freely rotate by hand, probably why the belt was broken and sitting in the back hatch. Needs to be replaced.
Belts/Fluids/Battery/Normal Maintenance – I’m surprised running this engine at all didn’t break the rest of the belts. They are in horrible condition. I’m sure everything needs to be done to this. Battery is of course shot.
Electronics -Radio doesn’t work (don’t care). Power windows are definitely showing there age, the motors are almost shot. Same thing with the sun roof (why did we even try to open that?). Most of this doesn’t matter. I just hope it isn’t a bad sign for the things we want. Electric door locks don’t seem to do anything on the driver’s side. Neither does the manual nob (key works though).
Clutch- Clutch pedal is sitting on the floor. Seems to be a hydraulics problem. This coupled with the bad battery means we couldn’t move this car under it’s own power.
Windshield – The only glass we actually want in the car is broken. We will need to find one of these.
That work was done in early August and that is the way it has sat until now. It’s been relocated yet again, to my house. My garage is going to serve as team head quarters for now.
Next up? Completely strip the interior, remove the sound deadening, skin the doors (remove all the glass and metal supports so its just a piece of decorative sheet metal) and get ready for the roll cage!
