I use my phone to stream Pandora in the garage, so I never think to get pictures until I'm packing up for the evening. Last weekend, with a the help of a friend, I got the motor dropped in and wired the COP's for sequential firing. I also eliminated a "sub-harness" that I thought was going to be helpful but really just made the wiring too damn long.

Turned the motor over a few times without fuel get oil up into the motor. As soon as I prime the fuel pump I get a whiff of gas. Well once I get the motor started gas is pouring out of the #3 injector. Guess I should have ordered those o-rings when I thought about it. Even though I never removed the fuel injectors from the rail, the o-ring was fubared.

So wait a few days due to the weather and work to get the injectors pulled, new o-rings, spacers, and grommets. Prime the pump and its good to go. Fired the motor up and let it come up to temp with no issues. I accidentally left my plate on a car I sold, so now I have to wait for it to come back before I can start putting some miles on the motor. I did do a little break-in work around the neighborhood and the mid range feels much stronger so far. Hopefully I'll get it on a dyno before my first track day in May.

It has been a busy past few months. I put about 1000 break in miles on the new motor. The only problem was a VVT actuator that failed a week before a track day at Atlanta Motorsports Park on Memorial Day weekend. So an overnight delivery the day before the event got me back in running order. The new found power really made a difference. Unfortanely I still haven't setup a lap timer in the car. That and running on 6 year old Toyo R1R's really put a damper on the lap times (somewhere in the 1:37-1:38 range based on following others with lap timers).

Also during that time I officially joined a Chump Car team. My first task was to turn it from a "red Miata" to something more recognizable. After some discussion we decided to play a little psycological game and paint the car different on opposite sides of the car. With all the late night hours I forgot to get good photos of the car before it was finished.

This weekend was our first race of the year and the National Corvette Museum Motorsports Park for a Double 7. On Friday I got in for the 2nd stint. With only 4 laps in the car at the AMP track day, never driving the track, and first time wheel-to-wheel racing, my only goal was to keep from making an *** of myself and keep it clean. After about 30mins I was within 1 sec of the teams fast times last year. At the end of the day we finished up in 5th place (with 6 place right on our bumper) and a Class A win.

The 2nd race started smoothly. I took the 2nd stint again and was able to move us up a few spots in the ranking and take over a second off my personal best (1:46.33). The last 45 mins of my stint I was keeping the lead car behind me (without any dirty moves, just using traffic to my advantage). After my stint, our 2 fastest drivers got in the car and moved us up to 3rd place. We pushed hard but just ran out of time and pulled back to save the car. The only contact of the weekend happened in the last 30min when the 5th place E30 didn't see us along side and they went mirror to mirror and messed up my fresh paint job. Then in impound the leading car was bumped to EC for running Ford EV injectors, so officially we finished 2nd. Our best finish ever for the team.




Next up is Barber in August. We are planning on leaving the car alone and improve the driver comfort with a blower system and drink system to battle through those hot Alabama summer days.

Barber Track Day prep:


The morning before the drama:


Well yesterday I got to join the prestigious broken throttle shaft club. While doing a track day at Barber Motorsports Park, coming out of the "corkscrew" I matted the throttle and then I felt it go a little further with a little "pop". I though maybe something had gotten under the throttle (had the fuse box cover come off the day before). There was a little more vibration in my foot, but I thought that was just where the pedal was against the floor.

I finished my session and started inspecting the TPS wiring (an intermittent issue) when I noticed the throttle return springs didn't look right to me. While trying to move them, this happened:



Pulled the intake in hopes the epoxy on the screw kept it attached the shaft with no luck...


I pulled the upper intake as well and didn't see anything. I loaded the car up for the trip home. When I got home I pulled the spark plugs and the #3 plug gap is less than the other 3. After some hindsight, I had the motor idling while inspecting the TPS wiring and I didn't notice any metallic "tinking" noises while it was running. I'm hoping the screw is sitting some where safe or it went through-and-through with minimal damage. I'm going to borrow a boroscope this week and check all the cylinders. I didn't feel any power loss and still a ran a lap within .6sec of my fastest from the day before. Fingers crossed...

Where did you purchase that rb2 replica bumper? I'm having trouble finding it, places that list it want 185 dollars for shipping, making it nearly $500 for a rep.

I borrowed a boroscope from a friend and removed the intake manifold to only find a small piece of the throttle plate screw in the resonance camber. I also found some damage to the top of the #3 piston as well. After I checked everything out and life got busy (Chump Car races, business trip to Australia, and a vacation in California). Finally blocked up a few evenings the last two weeks to wrap everything back up. I fixed the TPS wiring with a new connector from Ballenger. I fired it up this evening and adjusted the new to me throttle body and IACV. Runs just as good as before. Tomorrow I'll do a compression and leak down tests.

Its hard to believe it's been over two years since I've updated this thread. Not too much has changed on the car. Mostly just small updates, changes, and maintaince.



2016:
Upgraded to a S2 throttle body and ported my flat top intake. Took the time to clean up some of the castings flash as well.


I did a track day with Mustang Club of America at Atlanta Motorsports Park and made it into their coverage for the 2nd year:


We also moved into a new house with ample garage space:


Attended a track day at the Nashville Super Speedway for old times sake. The track was unused for a year or two and was super dirty. My front bumper took a rock blasting. A bunch of Corvettes and Porsches left with similar damage and were not happy


2017
Started off the year with big plans. I was going to switch over to ITBs and design my own intake manifold to work with Toyota AE101 throttle bodies I've had on the shelf for years.


Then we found out we were going to have our first child!


So that changed my plans for the year. I was only able to attend one Chump Car race. This year we took advantage of the engine swap and ECU rules and put in a refreshed BP4W running on a Microsquirt. They also updated the rules to allow more aero, so we went with a plastic air dam. I also through a new coat of paint on the car after replacing panels damaged by the Drive network E30 @ Barber in 2016. Made a knock-down paint booth in my garage. We competed at NCM in June with a newly installed surge tank. After burning up a pump on Day 1 going flatout, I had to drive Day 2 conserving fuel so the tank would stay fuel. We still finished in the top 10 and qualified for the Eastern Chumpionship:










The only other event I was planning to attend with Grid Life South. My only major change to the car was to swap in a 6 speed and 3.9 final drive (was a 5 speed and 4.3). While I was at it I swapped in a FM 10.3lb flywheel (aluminum one is going on a SuperMiata S2 I'm collecting parts for) and switched out the PITA BEGi spacer for a Hawley. I did find that the Hawley put the temp sender very close to the heater hose.






Tired of high intake temperatures and hot foot. I decided it was time for an air box/heat shield and some floor insulation:








Murphy's Law found its way into the garage. My freshly build 6 speed with a mix of parts was a failure. Apparently you can't mix parts from the MSM with standard parts. 5 days before Grid Life I had to pull swap transmissions. Come to find out my spare tranmission didn't have a working reverse. Went to the event anyway and just couldn't back the car up.



Grid Life South was a lot of fun. I turned a 1:46.2XX in traffic. There is a low 1:45. or high 1:44 in the setup, but I kept getting parked in the corners by slow Mustangs who would just motor me on the straights. I mounted up some 245 Maxxis VR-1's on my 9" wheels. Looking at some of the data, the 245's weren't gaining me enough time in the corners to overcome the loss in accel down the straights. I'll go back to 225's next year:





Had to ask my 7 month pregnant wife to help me back the car off the trailer.



Finally on 10/31 our first child, Shelby was born. Dog for scale:

Thanks. Every so often I think about selling is and moving on to another project, but I don't think I could do it. Too much time and experiences wrapped up into it.

I don't know how I missed this car at GLS. That front bumper gives the car a great look. You ran the car in HPDE+ class then? How'd you do?

I ran in Time Attack - Street Modified. For some reason I couldn't run HDPE+ (motor swap maybe?) I spent most of my weekend in Group D. I was pretty much the back of the field of Time Attack cars (71 of 92). Correction my time was a 1:46.4XX I did have a few great sessions with the FRS/BRZ group out there. I plan on going back next year, but just running the HDPE group. TA was too frustrating when you have low power on a straight intensive track. When your highlight of the weekend is passing a Mustang going into turn 1, I think rather be W2W racing.

Regarding your 2nd gear, is it possible the last owner unbolted the wrong bolt when trying to change the transmission fluid? I know that unbolting the passanger side bolt on the 6 speed will result in no reverse.

That is my assumption as well. That transmission is out of the car and getting an inspection and refresh in a few weeks anyways.
