So far all testing fitting is going really well.

I love making/ designing parts! I think it’s my favorite part of this strange hobby. This is a zero hole in my car EFI FPR mount. Next I will have it cnc cut. This is just 3D printed. Draw, design, test and make. So much fun. I really like how simple this radium fuel pressure regulator is. Uses a Bosch top. Very well thought out.

Spacers are done. This should work awesome

Here is my E31 flow data.

Tuners fight constantly about using TPS over map. It's a very polar opinion.

You will need to get a vac signal from each runner and combine somehow, either in a vac log or vac tank. Then send that to the map signal and the fuel pressure. Brake can run off the same spot on the manifold. My favorite new throttle bodies are the Borlas. The fact that they have the vac on each runner is a huge plus.

SK ITB update! Fuel rail is looking sweet!

The SU choke works very well. Maybe something is wrong?

My series 1 has the ones to the right.

Fits!!

Continuing my fuel rail path. Hopefully cutting this week.

I used the stock coil or at least a similar to stock coil.

My 123 worked perfectly in my 1/71. Your tach should just sense pulses from the coil and should be separate from the 123.

Coming along nicely. I got my injectors. They fit so nicely. Now working on angles and what I will do with the fuel rail.

I love it when a plan comes together! Vintage SK ITB is coming along nicely

I hated my brakes prior. I personally think the most money you spend on a car should be brakes. Since it’s your defense in an accident.

Unusual?

Got them cut. Next is more test fitting and then surface finish to match.

I removed that brake kit for the much much much better zcargarage BBK kit. I also got real wats:)

From idea to test Fit in a week. Cnc cut next week. Only tweak is matching the step and radius of the step to the throttle bodies. This will be a decorative mount for a single piece fuel rail.

Well this looks good! Next project is to figure out is the single piece fuel rail and mounts plus injectors. Then they are ready to go on. Vintage SK ITB is coming together.

Making vintage 40mm SK throttle bodies into 45mm. Machinist was amazed on how square they are. .003 off of true center. These are for Andrew Kazanis as a thanks for taking such good care of my 3.1L IMG_0189.mp4

Pretty proud of how these vintage SK throttle bodies came out. All new zinc, shafts and butterfly’s. I can’t wait for them to sing on my 3.1L

I rebuilt this 82-83 turbo distributor today. New bearing, all new zinc and a new z31 cas. only issue so far is the Cas disk I have might be bent. also Cas turbo upgrade method #2. This is for a 82-83 turbo distributor. Instead of using long nuts and bolts. I thought this would be a cleaner install. Drilled out the base to allow m5 jis screws. Then threaded and tapped the maxima cas
