Ok, so from part 1 of the engine build, you already know we ended up with two potential cars as donors for this build. We decided on the cheaper 12A bridgeport route over the 13B EFI route. With the engine on the stand and ready for teardown, work got start pretty quickly. Just a few pics during the process, but I’m working editing the teardown video together so you can see the whole process (if you’re into that sort of …

The third NASA-X event for 2013 season is completed. For once we had great weather! This event was sponsored by PTuning in Manassas, so we had plenty of FRS/BRZ cars running around and a lot of Novices running. Hopefully they got hooked and will keep joining us. The #62 MX-5 placed very well again, running a low 58s pass. The #78 RX8 came in behind him at a 59s pass and the #330 BMW came in at a 61s pass. …

Mike’s recap of the Southern Discomfort Event for the 24 Hours of Lemons: “Okay, my experience. I’ll first start with the team. Definitely a great group of people with a very high amount of attention to detail. Bonnie did a fantastic job as manager and kept it well organized. We never had any moments where we were scrambling around, bumping into each other. They are very friendly and engaging. I appreciate the experience on the track as it was my …

So while the body work and reassembly gets wrapped up, attention needs to be turned to the powerplant for the RX3. Keeping with the GRM $2013 budget (we may need that extra $1 this year) we wanted to keep it simple but still make decent power to post some decent times during the dragrace portion of the challenge. The car HAD a bridgeported 12A in it that more or less detonated and left very little useable parts for a rebuild. …

In the coming weeks, there are lots of projects to be completed on all the Twitchy cars. With an engine build and install into the RX3 and the #78 RX8 getting new exhaust work, the #62 Miata isn’t being left behind without some attention of it’s own. When seeking more power in the NA generation Miata, there are literally hundreds of options available. You can count on a laundry list of choices. Fully built naturally aspirated, little or big turbos, …

Finally got around to installing the brake proportioning valve on the #62 MX5. It will allow for fine tuning of the rear brakes in relationship to the fronts. The kit allowed the adjustments to take place in the engine bay which wasn’t ideal. If you have the transmission out, it is easy to mount it to the side of the trans tunnel and run a new brake line. For me, I got the Wilwood remote kit and worked with that. …

When I was setting the timing for the dyno, I found I could only get 10 degrees BTDC. My research showed that meant my exhaust cam was off one tooth. I also had an odd noise and suspected an idler pulley. What a perfect opportunity to investigate and set the timing! What I discovered was that in fact my exhaust cam was off one tooth. I decided since my timing covers were off the car I should clean them up. …

We took several videos, but honestly… not many turned out that well. I guess we’re a little rusty from the winter temperatures! Either way, this baseline dyno was very helpful in detecting not only the current state of our 1.8’s health, but also that the factory tach unit is about 500RPM off. Enjoy this for now and hopefully later this season we’ll have a much more exciting dyno video to share.

In preparation for a new NASA-X season and to prepare the MX-5 for more road course action, it was decided a few things would need some attention. First off, maintenance was the general theme amongst both the MX-5 and RX8 this winter. After multiple track events and races, the cars needed some much required TLC. The MX-5 had a failing rear wheel bearing. Upon trying to replace and repair it, it was discovered that the entire hub assembly in the …
