no longer "retrospective"
Well from this point forward this build thread is no longer retrospective thus the progress will be slower. I have all of the dings out of the car, it is primed and almost ready for painting. I am at the mercy of my good friend who is going to paint if for materials only. He says we wlll be done in 3 weeks because that is when I am planning a trip to the Ennis Motorplex with my son to see what it will do in the 1/4 mile. Anyway.. I tackled a few projects while waiting. First I installed a pair of tweeters.
They are the fancy kind that cost 7.95 for 2 pair on ebay. They are held in place with a strip of metal wrapped with a bunch of electrical tape. I also ordered a pair of pioneer 8 inch marine speakers. I will wire up the tweeters when the 8 inch ones get in. I can't install the door panels until after the car is painted because they would just have to come off to reinstall the door handles.

Rework the front intake snorkel
I installed a G5 X1 cam from LG Motorsports then took it to them for tuning. It has much better manners after their tuning session however they were confused as to why it only had 306 hp to the rear wheels. He suggested that I get rid of the single 2 1/2 inch exhaust and rework the intake snorkel. So I started with the intake snorkel...
First I took off the corvette one then put tape over everything that I didn't want the spray foam to get on. Then I sprayed the foam. Remember to go one layer at a time with the foam otherwise it won't cure. That stuff is sticky!!!!

Next I took the foam and all of the tape off the car. Then I proceeded to shape the foam into the exact shape I wanted with...you guessed it... a $19
Harbor Fright orbital sander with 100 grit paper. Once the final shape was obtained, I wrapped it with blue masking tape then covered it with several
layers of fiberglass. It is easy if you cut the fiberglass into 2 inch by 2 inch pieces, use vinyl gloves, mix the resin in red solo cups and use cheap disposable brushes to apply the resin. It took about 3 batches to get it as thick as I wanted. I used the mesh type fiberglass rather than the cloth type. That is just what I had left. After it cured, I took the foam and tape out. Some of the bits of tape would not come out until I got the dremmel after it. Here is a pic of the corvette snorkel and the new one side by side.
I bet the new one flows better!!!
Oh yea... you are probably wondering how it is attached....well the top portion goes inside the rubber boot that the corvette one went into. I had to sand the new one quite a bit to get it to fit and to get the surface of it smooth so that there would be no air leaking around it. I went over the bottom part with some gorilla tape then used hose clamps on top of the tape then painted all of it. I am confident no dirty air will get in.

It does appear that way. I spent quite a bit of time this past weekend trying to figure out how to do a ram-air setup in which those air filters were put inside a can and a duct run down to the fog light holes in the bumper cover but bailed out on that idea because of the same concern.
I had this setup (with the corvette snorkel) last
summer and it did not have heating issues even with the AC on in this Texas heat.
I suppose if starts running hot, I could move the filters more laterally.
As it is, the air goes around the filters and the total surface area of the radiator is still more than the air opening in the bumper cover or the two circular areas my stock ls1 fans are moving air thru.
I'm going to use the fog light holes for brake ducts.

I promise that the pinion shaft is in the exact center of my car. The back part of the transmission tunnel on the miata is also designed to have the pinion shaft offset one inch. I just had to beat the crap out of that part of the tunnel so the u-joint assembly would not rub. If I had it to do all over again...I obviously would do it with it moved over an inch but by the time we figured out what happened...One of my axles had been shortened so it was easier to lengthen the other one than it would be to get both of them re-made.
So just to be clear, the axle shafts were equal length? But they didn't work because you centered the pinion rather than having the same length from the hubs to the axle input on the diff? I am curious because I ill be making my diff mounts this weekend.

motorplex date
I'm going 6/26/15 I sure am hoping they aren't picky about tech stuff. NHRA has some pretty picky rules regarding convertibles. My Boss Frog double hoop rollbar won't pass inspection but I have heard from my uncle who races his mustang that they aren't too picky on test and tune nights and the motorplex advertises that if it is street legal and you have a driver license..you can run. We will see...

We will record action. Jim, you can probably relate to this.. .my son from who is stationed at Virginia Beach in the Navy is coming in. I plan on us taking turns to see who can get the best ET.

You are correct. I highly suggest you wait to weld your differential mounts to the subframe until you get your axles. Put the axles in and get equal play on each side then tack weld the differential mounts to the subframe. When you do this the pinion shaft will end up 1 inch closer to the passenger side of the car and everything will be great.

I'm pretty sure I will get slaughtered too. There are tons of mustangs and camaros out there running faster than the 12's. I'm expecting to get around 12.5 but we will see. I have 315 street tires on the back and only running a 2400 stall in my automatic transmission and I still have a single 2 1/2 inch exhaust pipe. I'm gonna try to get that changed before I go but I may run out of time. The front fenders, hood, bumper cover, door handles, mirrors and antenna are off the car right now awaiting the paint job.
6/7/15 update... I'm considering a rear mount turbo. It will require a single exhaust inlet so for now I will wait on the dual exhausts. It looks like STS went out of business and had issues but I am considering a 76mm oil cooled turbo that has it's own circulation pump, tank and cooler mounted back where the muffler goes.

I attached the motorplex schedule for this year. Just show up on a "Fast Friday" night. I can be the Guinea Pig and see how picky their tech guy is.

But anyway...I'm going to try to make it on the 26th. I'll be taking it especially easy since I won't be able to trailer (Jeep will be loaded). Having to drive home is motivation to not break stuff.

The parks I go to don't typically have bands (that I am aware of). It's a rock crawling thing. Sounds like you are talking the mud pit places (Red Necks with Paychecks?)

I'm driving my miata to the track without a trailer... hope it doesn't break.

Nope. The front ones are not painted either. The painter and I spent 8 hours on it Saturday getting it ready to paint. Looks like this Sunday is the day for it to happen. It isn't as much fun working on now that the heat index is approaching 100.

Now wait just a dog gone minute here you guys! Jackie and Edgar are both talking about fiberglass on fenders yet no photos or threads in the exterior section from either of you. As a person who built his own wide body fenders from nothing (in the most difficult way possible) and documented it, https://www.v8miata.net/v8-miata-whe...1462/#post8530 I call a flag on the play! Come on lets see em boys! https://www.v8miata.net/exterior-mods-37/
