Well the last few months hasn't seen nearly as much work as I had hoped on the car. But good news is that in the last few weeks I have made some good progress on it.
As of today everything is out of the car that needs to be other then the rear end. I am ready to start putting things back together this weekend and hope to make some good progress on it.
So the current plan is to install the new clutch/flywheel and transmission on Saturday. Once those are all in I can reinstall the headers and super charger. With all of that being out I am working on removing the power steering pump and extra pulleys from the belt system for the super charger. Doing this will help simplify the system and remove some parasitic drag on things, freeing up some power. Probably won't make much of a difference but its worth it just to remove unneeded parts. Once the headers are back in I can reconnect the steering column and then install the shocks. Then the front end is done.
The rear end is coming out this weekend to head into a shop to have the 3.636 ring and pinion installed. I should have it back in just a day or two after dropping it off. The following weekend I should be able to get the rear end installed and hopefully fire up the car.
Things are starting to progress finally!

Long time no update...
Well, its been a while since I have updated the blog. All in all it was an ok season for autocross. Did alright but could have been better. usually in the top 5 at events for raw time and about the same for PAX. I did discover at the last event of the season, on October 11th, that the Hoosiers are shot. What I have mounted right now is a set of 275-35/R15 that were used before I got them. If you can get them hot they aren't bad, but the 11th saw sustained winds of 19mph all day long and gusts of 40mph. To say the least, the tires never got warm. At the end of the day I had switched to the R1R tires and was packing up to leave when a friend showed up that wanted a ride. We did a buck run with out the Hoosiers and, holy crap, what a difference. the car felt planted and could accelerate out of turns much better then with the Hoosiers. To say the least... I'll be getting a new set of Hoosier A7 next year.
Current plans for the car is to have the shocks serviced and put on some stiffer springs, 800 front, 550 rear. As of today the shocks are on their way back to me and should be back in the car soon with the new springs installed. After its a matter of the drive train. I have a 6 speed transmission to replace the 5 speed. The catch is that it makes the gear ratios awful.
5 - Speed + 4.3 rear end and 7200 rpm rev limit:
1st gear tops out at 35.87 mph
2nd gear tops out at 59.57 mph
3rd gear tops out at 84.57 mph
6 speed + 4.3 rear end and 7200 rpm
1st gear tops out at 29.91 mph
2nd gear tops out at 49.57 mph
3rd gear tops out at 68.37 mph
I purchased a 3.636 ring and pinion to put in the differential which will take care of it.
6 speed + 3.636 rear end and 7200 rpm
1st gear tops out at 35.38 mph
2nd gear tops out at 58.62 mph
3rd gear tops out at 80.86 mph
Much better and very close to the original ratios. All in all I'm sure I'll have to learn to drive the car again with this many differences.
I also purchased a dead 1992 Miata. This will eventually become the base for everything that's in the 99. the car has about a softball sized hole in the block where a rod went through it. in the end this one will end up about 200-300 lbs lighter then the 99. this probably won't be in service until 2017. Going to take my time and do it right as I build it.

First update of 2015!
Its been a while since I have posted anything. Weather hasn't been very good for getting anything done.
This last weekend it was 60f so I got off my butt and finished putting in the replacement drivers seat that fits me better. It is another Ultra Shield seat like the old one that I purchased from a fellow club member a few years ago now.
Other projects on the list include installing the Flyin'Miata tow hitch so I can pull my trailer to events. This hitch is nice and light weight adding only 8 lbs to the car. I am also considering the Flyin'Miata butterfly brace to stiffen up the whole car.
For now, I just keep eyeballing the calendar wishing it was time to drive!
