Default NB - 83 Mustang drivetrain

Hi folks,

It looks like I have posted enough on the Introductions page to start a build thread. I bought a 2002 LS at auction in late October, after roaming this site for close to two years, and scheming. I've owned a 1983 Mustang GL since college (drove it a few times in high school). Over the years I've replaced about everything and after a season of autocross have decided it will not take me where I want to go - driving to and from autocross and open track / HPDE events and having a great time.

So, best of both worlds - the handling, brakes, light weight, top-down general fun of a Miata with the best part of my Mustang - the '88-based 306 (carbureted; 275whp, 300 ft/lbs) with a T5.

This will start slow since the NB runs (203k miles). I plan to do some autocrossing and perhaps an HPDE event this summer, and then get to work on the driveline transformation next winter. By then I will have an insulated garage. :-)

As noted on my intro page, I lucked upon a winner - lots of aftermarket parts, including Eibach springs, Koni shocks, and a Koyo radiator. I've bought Hawk HPS pads to go in all around, I'm changing the fog lights to brake ducts with LED DRL surround, and I am adding some bracing - stitch welding around the door sills, 1" square along the bottom pinch weld. I also plan a rollbar install (still deciding BBFW or custom local) with eventual door bars, an install of my Momo racing seat from the Mustang, harnesses, 2" tube rather than subframe braces, and I may need to drop the floorpan. I'm still sorting out how I fit with a helmet. I'mm definitely staying with the soft top - my Mustang is a T-Top and I love the open-air approach.

Lots more to come, slowly. I have learned so much from this forum already and look forward to the give and take over the next few years.

Sounds like a good plan.

Cool always look forward to new build ideas

awesome for jumping in, I am hoping to finally get back to my build after a 14 month delay, started a new business last year and just now starting to get the time to think about returning to my project. Remember to have fun and post pics and ask questions. This community is excellent and offers some great advise..

I was working on a few things over the winter. It is now getting warm enough that it is comfortable to spend time in my NE Ohio garage. I've pulled all of the interior but the dash, and did some seam welding around the doors (fusing the various layers together). I'm also removing the rusted-out fog lights and installing front brake cooling ducts in their place. I had purchased stock-sized Centric rotors and close-out Hawk HPS+ pads from Tire Rack. When I dug in to install them, I found that all four calipers were in various stages of complete failure / deterioration. So, I picked up some Powerstop rebuilds from Summit. I should be able to trust the brakes now (flushed all of the oil fluid out as well)! Last item was to weld 1X1 square against the sill seam, to provide a reliable jacking point, and to eventually tie into a reinforced subframe rail under the seat.

Cooling duct-inside. 3" at opening, 2.5" at spindle

Seam welding

Completely shot!

Yep, the rear brake pad actually flaked off the backing plate.

Rusty old front caliper

New front brakes

New brakes!
