So you 3d printed those? Pretty slick solution

3D test printed. Now off to Cnc cut.

Rainy Sunday z project! Finally got my cable mount installed for my new cable driven ITB setup. This is a lokar cable to a stock 240z pedal with the ball end removed. Then I made a tiny bushing. Everything is snug and works as it should.

Duff, 

im confused. Aren’t you using DBW?

Dbw will be down the road. I first need to get the car up and running with the new intake. 
 

dbw requires a new ecu and more effort.

Well I ended up selling my SKs.  I am going EFI hardware pro throttles and a vintage FET V1 intake.  The FET has about a perfect injector angle and should spray fuel directly down the middle of the runners.  

 

The only real issue is they have huge ports at the head, so I will be welding them up and matching to my head.

I got the idea for the angle here.  This is a Fet v2 or v3.  The issue with those intakes is the middle carb/ throttle is higher. So you can't run a solid fuel rail.  Also this version of the FET has 30mm runners at the head.  So lots of porting is needed.

Also working on a new coil bracket, this one has a built in angle for the boots not to be bent so much.  It was cut on a 5axis cnc.

Here are the coils installed.  I don't love the boots, so I am looking into have stock style made.

I am working on the stalks now, 3D printing and test fitting how the stock springs will work.  The goal is cheaper and rigid like the stalk coils, I plan to make and sell a few of the brackets.

Also I got my taper bore pro EFI hardware 45mm throttle bodies! They are cnc cut and very pretty, the have the most shallow injector angle I could find, and I love the bearings, 8mm shafts and butterfly angle.  Sadly they were damaged in shipping, so back to waiting.

[duffymahoney]

Since my throttles are taper bore.  There isn't a velocity stack that looks classic and is the correct size, so I had these drawn up and cnc cut.  Sadly I screwed up a measurement, so they have to get cut again.  These are 65mm length stacks, which I think make them look better with the shorter throttle bodies.  Thoughts?
