In the past when I would bench and smooth out casting lines in parts you would always see the smooth ground areas in contrast to the original casting finish.  What I would do is blast it with a heavy 36 grit aluminum oxide to add even texture on the entire part, then Vapor hone it to brighten it up.  It looks great, almost as if it were originally cast like that.  So something to consider vs just glass bead if you decide to smooth out any of the maching marks and go with a more classic cast look.

Got any pictures?

All ITB test fitment is done. Cable mount is perfect, everything is smooth and actuates as good as I hoped. Now time to bolt it down, cut the cable to length and finish some wiring.
I lined up the MZR haltech tuner to help me with my tune. It should be interesting to see how good he can get it, especially with my balance bar design and throttle angle.
Will the snow melt so I can drive it soon? Probably not.

Looks like the same pistons I run with the dish . Smart man to put arrows on the pistons. You won’t put one in the wrong place like I did - lol. 

That's Andrews work! 


Pistons are eagle, sold by rebello.

Something fun I have been working on! I really want drive by wire on my 240z. But figuring out a location for the actuator has been tough to say the least. I don’t want it hanging over the intake. 

This is a 100% bolt in adapter featuring a BMW 6 cylinder actuator and a 350z pedal. This will attach to stock linkage and drive my ITBs. Hopefully it works! The pivot arcs a far bit, so that might not work and the pedal mount might flex too much? Time will tell. 

This would allow me modern cold starts, any sort of progressive pedal movement I could want. Full idle control, traction control, valet mode, cruise control and way easier tuning. 

We 3D scanned the pedal area and the actuator to mock it all up in CAD! 

All of this is 5axis cut out of 6061.

Well it works. But the firewall flexes too much, next I will try to mount to the pedal box which doesn’t flex at all. I also want to keep the arm movement on the same plane. Currently actuator is up and down and bell crank is left to right.

New ITB intake is getting sent off to China to CNC cut! This fixes a few mistakes on the first version and also gives me the stock J-hook pivot as an option. It will feature a bolt on banjo balance bar and ideal injector angles. It's slightly longer then the last version as well.

Well drive by linkage is fast and accurate. Pretty darn stoked. I might try a few more actuators. Since the one I picked is being discontinued (BMW S54 13627840537)
This should make anyone doing ITBs life much easier. Cold starts, traction, AC, intelligent throttle curves.
This is just hooking it straight to a 12v source. So it’s just on or off. Actually when wired to the ecu, closing will be faster. This is returning via springs. When hooked up to the ecu. It’s powered open and closed.
