1982 Mazda RX-7 description

Up for sale is a well known FB (amongst the FB owners that have been around for a while.) This car was built by Billy Watts the original owner of RE Speed.
The car now has a rebuilt 13B with a Camden Supercharger. The paint could use a little touching up and the front air damn needs a little work.
The car has a Pacifica Widebody Kit on it painted blue and white. The car is street legal with but is best served on the track.

The write up below was written by Billy Watts...

"The shell was completely stripped of all parts. Shell was then prepped by aircraft stripping all the wheel wells, interior and engine compartment. Once clean we began to repair the wheel well rot. Sections were cut out and new sheet welded in place. We used new upper arm support brackets removed from a donor chassis to complete the repair. All non used holes were filled on the firewall with round slugs cut from sheet metal and welded in place. Once the welds were ground down you can not see where the hole were. Threaded bungs were welded in place for the hood pins and the fuel pressure regulator bracket was fabricated and welded to the pinch weld on the firewall. Brackets were fabricated and welded for the second generation oil cooler mounted in front of the radiator. We then covered the tire well with our normal fuel cell block off panel though we have chosen to stay with the stock tank for a while. A simple 4 point bar was fabricated from 1.5" x .095 wall DOM. The bar was built to help support the rear shock area for possible future updates in the back. It was also built so that it can be updated to a full cage later. Once chassis fabrication was completed we sprayed the engine area, interior and wheel wells gloss white.
Our goal with the car is a streetable, track day car that represents our abilities and product line. We wanted to build the vehichle with an "old school" look. It will be used for a few track days her an there as well as to show the vehicle at events like Deals Gap and SevenStock. To attain this goal we decided there would be interior from the main hoop forward. There would be a full street legal wire harness. All the parts for the vehicle would come from our online store or our available sources just as our customers would do."
The following list is what was used and done during the build:
