Been looking at this thread for quite some time in the past months. Any new updates?

Sorry I haven't updated this often. I have been super busy with work.

This is stuff I have done, but have forgotten to post it online.

Anyways, one of my co-workers got some dry ice to remove the sound detening from his AE86. After he was finished with it, I used it to get what I had left off of my floorboard. It works wonders compared to the chisel and hammer technique I was using. Like usual, here are the pics.

During



After


I started making a fuel surge tank, aka swirl pot. It goes between the fuel tank and fuel rail to make sure I get every last drop of fuel, even during hard cornering. I will have 2 low pressure pumps pulling fuel from sumps to be made on the oem gas tank pumping into the swirl pot, and a large high pressure pump after the swirl pot to feed the fuel injectors. That way no matter what, as long as the surge tank has fuel, the car will not get air mixed in. I am running this setup and not a fuel cell, because the race series requires FIA-3 approved cells. Those start at $600, and the blatters need to be replaced every 2 years. This works without having to be "serviced". plus the weight of the fuel will be lower and more centered.








The EFI pump will go next to the pot, more centered in the spare tire well.





And it complete



Next in my long lost pics is is300 vs sawzaw.

The original plan was to deal with the suspension later. Before the car drove, but after most of the chassis fabrication. This plan changed when a good friend (stancel) decided to try to drift up the rumble strips at road atlanta. That did not end well for anyone.



I donated my good suspension to him. He replaced the items that he broke that I do not plan on upgrading (axle, hub). The toe and trac links both got damaged on the driver's side. That gave me the incentive (car is stuck on jackstands) to get the car rolling again, literally.

For this, I contacted the guys at allstar performance (big in dirt track). I know other companies make these products complete, but this way is just more fun



It took a few orders to determine exactly what I needed, but I finally got everything. The toe rod was fairly simple, just assemble the parts. I might have to ream out the tapered hole on the hub a little because I ordered 1.5" per foot taper rods, and the stock ones are 1.33" per foot taper. They fit close, but not quite perfect. The trac rods required cutting off the old mount and transferring that over. The chopsaw, and tig welder made short work of that job. Here are the finished ones next to the oem ones.







Here is everything complete, also are the sway bar endlinks I ordered.

No worries on that. We have 2 go pros waiting at the shop for it to get done

I started stitch welding the car. It is the biggest PITA on this project for multiple reasons. First, ALL of the factory sealer must be removed, not just on the outside of the factory edges, but inside all the cracks as well. Some people use heat guns, but I prefer a wire wheel. This method is a lot messier, but gets the job done quickly. Then a pick to get in all the groves and remove the little bits by hand. A smaller wire wheel preps the area for welding. Here is a pic of the mess.




And some close-ups of the prep process.

Ready for welding



The last step in this process is welding; I decided to do approx 1” dashes instead of dots. It is just easier once started to continue the weld.

Here are the completed pictures. As you can tell, I have done less than ¼ of the car, and this took 6 hours so far.

That is such a fun job. Clean the sealer out to do the welding is such a pain. Good job.
