Well, 95% of the wiring is done. The list of the last 1,000,000 little things is down to 36 items on the list now. With any luck at all, she'll come to life this weekend and I'll be shaking her out at Nashville Super Speedway the weekend after that... fingers crossed. A few pictures:
Dan made a really really nice passenger foot kickplate/bulkhead. I have some pictures, but it really doesn't do it justice. Dan may post some, or I'll get some better ones of it later.
Hatch and wing are on the car now(still have to drill the holes for the hatch pins) as well as my 18x10 CCW's. I'm going to give the 275's a try and see if I can get the power to the ground on track. If I can, I can keep an extra 30-40hp. If not, I'll put the flares on and run 335's in the rear, but have to tune it down to lose that extra hp.... double edged sword.
Dash with switches:
Dan wiring stuff in with his new earphones. They are noise canceling with microphones. You can literally be whispering on the other side of the shop and he can hear you. but it cuts loud decibals out. There was a trans am on the dyno earlier in the day.
Old and busted:
New hotness. Toe Links and Trailing Arms from Ben at Rotary Extreme(thanks man!)
I have the intake finished for now, but I'm waiting on the next Samburg Radiator/CAI group buy so I can replace it.
Hopefully I'll have a big update this weekend.

Well gentlemen... she's ALIVE!

Sorry about the poor quality, the dim lighting didn't seem to like my crappy HD camera. At the very end, Brian blips the throttle a little and you can hear a little better.
Before I get into everything, I want to thank Dan and Brian for all of their hard work on this car. We all have day jobs, day jobs that require alot of time. We have been over at the shop pretty much every night of the week from when we get off work until no earlier than 10pm and as late as 12:30am as well as every weekend working on this thing. Needless to say, all of our significant others are just as ready as we are to have this car finished... and so are we
The last week:
We worked on the car all weekend. The alignment and corner balance were completed on Sunday. I'm going to put a line of space in this...
Final Corner Balance:
Front/Rear: 49.6/50.4
Cross: 50/50
How awesome is that?
Anyways, we were ready to push the button on Sunday to start the car, but Jerry(Corvette guy at the shop) was at an SCCA club race at Road Atlanta so we were fairly certain that the ecu would throw a theft code and not allow the car to start. This was confirmed by turning the car over as well as pulling the engine codes. No big deal. We were also having an issue getting the fpr set to the stock 58psi fuel pressure.
Monday came and Jerry loaded a different map into that should be a little closer to my application as well as turned the theft device off. The car still wouldn't start. Well, after troubleshooting for a couple of hours, we discover all 8 of the injectors are bad. We did this by using the same method that is posted in my fuel troubleshooting thread on this forum. I assume it's from where they sat for so long they just got stuck. We were able to locate another set of injectors at the shop, threw them in, and it wasn't a 1/4 of a revolution and the car SCREAMED to life! Pay day. We let the car run for 20 minutes or so. Everything was working. The fuel pressure was high. Oil pressure was good, accusump came up, etc.... everything was working as it should. We shut the car off and went to Krystal to have a celebratory dinner(around 10pm).
Tuesday we come in and check the car for leaks. One little oil leak on one of the adapter fittings for the oil cooler that needed to be tightened a little more. Now no more leaks. We discovered that what we thought was fuel pulsation dampener on the rail, was actually a stock fpr. The aftermarket fpr was removing and the stock one holds 58psi no problem. Problem solved. I picked up a couple of little things I was needing like shift ****, exhaust gasket, and oil catch can(brian put it on) and put them on. Jerry is looking on the computer and realizes our MAP sensor and TPS sensor are not working. We have to have the MAP sensor functioning to be able to tune the car. In order to get to the map sensor you have to pull the fuel rail and intake manifold off which is extremely simple. After replacing the MAP sensor, no change... still not working. At that point we called it a night.
Wednesday. Brian started troubleshooting the MAP sensor. We had a couple of hang up's, but after a couple hours, Brian discovered the MAP sensor was wired in backwards. So much for purchasing a custom made stand alone harness so you don't have to deal with electrical issues. Fixing the MAP also fixed the TPS. We installed my widefoot sway bar mounts and the sway bar off my silver car. The clutch pedal stop bolt was adjusted and now we have a functioning car that moves I'm sure more stuff was done, but it all kind of bleeds together at this point.
Today, I'm going to drive the car around a little to start breaking everything in some more. We are hoping to have everything done tonight. Tomorrow will hopefully consist of me driving the car around a bunch and really breaking it in, followed by Jerry tuning the car, and loading it up on the trailer and getting it ready to make it's track debut on Saturday.
I'll see if I can't get my pictures uploaded here after while.

Very nice! Congratulations Brent!
Please tell me you aren't going to VIR this weekend?! I was supposed to be going but had to back out at the last minute. If you are there with your new toy it will further deepen the wound of not being able to make it!

Dude, congrats, that's got to feel good getting it fired up for the 1st time. I so want a ride in that thing 
BTW, CCWs are my favorite wheels, they look sick on your car!!!! Like I said before, you must post in car video of this thing on the track Hell you should post a video showing the car from the outside too, a walk-around kind of shot you know.

Back from the track!! The car did awesome!! I did get one video today, but it's prob. going to be really crappy because I really don't have anywhere to mount the camera. I'm going on 2 hours of sleep right now and I still have more stuff to catch up on, but I'll go a little more in depth here after while if I don't pass out first.

Hey Brent, Nice build. We met at the Zoom fest event and PDX. I just picked up another FD I am building for track duties. I was wondering if you could provide me with 2 things. Pics of the complete dash installed and a thread ( if it exists) of the cage build or some more pics of the cage. I want to give my builder an idea of what has been done in FD's.
Thanks, hope to see you at this years Zoom fest as well.

I'll see if I can't get you some pictures of the dash. As far as the cage, it was already in the car when I purchased it. I think there are already quite a few pictures of it in this thread, but if there is something specific you'd like to see, let me know and I'll see if I can't snap some pictures of it. Hi Niles, what Dan said above
The car originally weighed in dry at 2250lbs. At that point, it was looking like it would be around 2600-2650lbs with me in the car... which wouldn't work. My class is a 8.7:1 power to weight ratio which would mean I would have to de-tune the engine to less than 300hp. I added a few things and now I can have 330rwhp. We are still having issues getting it that low by simple ecu de-tuning, but I think we are going to run a restrictor plate or a stock LS1 throttle body to get it within class specs.

Yep, it was n/a then. I have since rebuilt to a different set-up. Came to the relization that a HB was a waste of my time and $$. Back to a SP and turbo for track days until this is built.
If I can't find any shots I need I will ask or just grab them when I see this thing.When is the next time you plan to make Road Atlanta?
One more question,.. Did you guys cut the floor and lower the seating mounting?

I'll be doing the NASA event in June at Road Atlanta.
Charlie from Mazcare and myself both have the lowered/sectioned floor in our V8 FD's. I don't think it's really necessary though. The best advice I can give you on the cage is to buy your seat first, and have your cage built around it. I'm assuming that if you are caging the car, you are looking at getting into racing. I would get a seat with a Halo so you have side impact protection as majority of wrecks involve side inertia. I think the HANS pro and HALO seat are the best comboniation on the market. That's just my personal opinion though. It's certainly not the cheapest option though. I just picked up a Race Tech seat with the Halo and it would of been much easier to put the seat in and then build the cage. I'll make it work though as it does physically fit in the car, it's just a big hassle with the door bars, rear bulkhead and bars, and diagonal cage halo bar.

I am attempting to get to the June event as well. So much to do though. Brakes, tune, tires etc...
Yes I plan on getting into time trial and such. I appreciate the advice on the Halo. I will do that as safety cost I do not try to "budget" I like living. My concern with not lowering the seat will be head room. But the seat alone should gain me a couple inches hopefully.
Can't wait to see and hear this thing run around RA.

Yeah non-sunroof 93 SS touring to start with. Time to start gathering bits and pieces,.exspensive bits and pieces I am putting the car on a frame rack within the week to check things out to be sure I am starting with a straight chassis. I am thinking it will be 2-3 years depending on how business goes Fun project to plan out anyways.
Just found all the pics I wanted on page 2. They didn't show up but for X's for me 2 days ago when I looked. Sweet! Dan does some really nice work. I love the dash.

Encountered a few new race car build pains, but nothing that won't be remedied in the next week or two. Car was at CMP last weekend, but I had some transmission/clutch issues so I didn't compete in the Time Trial. I drove some sessions in DE to show my student a few things. Here are a couple of pictures with the everything painted and my stickers added:
I did the prep work and sprayed the primer and Brian sprayed the base/clear behind the shop. I'm happy with how it turned out.
Next event is VIR May 21-23 with several fellow RX-7 track rats. After that, NASA Time Trial at Road Atlanta in mid June.
