LS1 Miata Build Thread
Compliments of fourwhls @ http://www.roadraceautox.com
I have discussed this build quite a few time on here, but I figured it was time to get off my ass and document it. I'm not even sure this is the appropriate place for a build thread, but since there is so much fabrication and design going into it, it seemed appropriate.
My build started in November 2009 and is still not done.
Procrastination and having a great co-drive for autocross has slowed down the progress significantly. My autocross season is from March to November, note the lack of progress in those months.
My goal is to have it done for my first local autocross in March 2011. I am off work the next week and hope to get a lot done.
The following posts with dates at the top are to get everyone up to speed. Here we go....

Here's a couple "before" pictures of my car. I have some in-process tear down pictures that I will add later.
I will try and document the progress here: http://picasaweb.google.com/fourwhls/MiataV8#
Hopefully I will keep the camera handy this time. I said I was going to take progress pictures with previous projects and never kept up. I always got the start and finish, but missed quite a few in between.
The tear down begins....
Now you see it...
Now you don't...
I gutted an ASA Stock Car. Stand alone harness, every hose, switch, wire, gauge, oil tank, etc.
I left an empty chassis.
Donor rear end (only housing, limited slip, and half shafts will be used)
I had a few hours to mess with my car this afternoon.
I drained the gas tank, then removed all the fuel lines. I then starting cleaning up the last few items in preparation for starting the tranny tunnel cutting and got completely side tracked.
I decided I wanted to get rid of the trunk release and gas cap release from inside the passenger area. I had a set of hood pins sitting in the garage, so I pulled out the drill and went to town. I completely removed the trunk latch as well as the release cable.
I then got a little creative with the gas cap release. My initial intention was to leave the cable in the trunk and open the trunk and pull the cable to release the gas cap. I thought it through and decided to go a different route. I built a custom mount and put the gas tank release where the driver's side license plate lamp would be. I can now release the gas cap from the outside. Kinda overkill, but fun.
Here are a few pics.
