My desire was to have a “streetable race car” for a few years to iron out any driveability issues. This way I could motor around on public roads before I pulled the registration and made it a track only car. It’s much easier to fix a car if you can drive it every day to figure out what’s wrong vs. once a month at the track. So first up Maryland state inspection. Uh Oh...Problems! Surprised? Not really as I wasn’t expecting a 17 year old car to fly through the inspection. What did they find? Merely a broken passenger side motor mount, worn out front brake pads, and umm..... Some rust. Well actually lots of rust. On the painted side of the car it looked ok for a 17 year old car. Underneath however was another story. Exposed to the Pennsylvania salted roads and snow the underside of Rusty was in pretty poor shape. Several dime sized rust holes when cleaned up turned into 8"x8" sized missed pieces of the underbody. UGLY. Had to get these fixed before it would pass inspection.
So I set to work cleaning up the rust underneath. The whole deal from wire brush to
grinding wheel was used. Possibly one of the dirtiest jobs I’ve ever had the pleasure of
performing. All exposed metal was sprayed with a rust inhibitor primer/sealer. New sheet
metal patches were cut and riveted in place. Welding would have been better but remember
the budget. All the exposed joints were gooped up with roofing tar before the new panels
were installed too. And the whole enchilada was given a good dousing with rubberized underbody
spray. My biggest concern was of the structural integrity of the chassis given the extent
of the rust damage. My neighbor an ex-racer and mechanic whose advice has been invaluable
to me laughed it off saying I should have seen the Fiat he used to race in the 70's.
Rusty’s frame rails were essentially untouched and with the addition, eventually, of a roll
cage the chassis should be adequate...I hope. If not donor shells for the 2nd gen RX-7
are pretty cheap at about $500. On the bright side I swept up about 3 pounds of rust
debris! Weight savings? So with new motor mount installed, new el-cheapo Pro-Stop front
brake pads from Pep Boys, and rust repaired the car passed inspection and was registered with
the MVA as street legal. Oh and I also had to replace a headlight - high beam out. The next
hurdle would be the state emissions test. This worried me more than anything else. More on
this later.
