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? Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted February 6 Author Share Posted February 6 (edited) I launched my Datsun parts company, for anyone looking. https://www.m2racing.com/ Thanks! Edited February 6 by DuffyMahoney Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted February 24 Author Share Posted February 24 ITB update! I got the dog bones/ rods shortened, design and had the cable mount made plus the fuel rail mounts. It’s almost ready to bolt in! I might try some surface finishing on the cnc intake. I don’t love the look of it. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted February 27 Author Share Posted February 27 (edited) Finally got the linkage sorted on my ITB. This is without an over head bar return spring (I will add tonight). The system is very smooth and returns strongly. Pretty stoked.; Edited February 27 by DuffyMahoney Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted March 3 Author Share Posted March 3 I finished the injector wiring. I cheated and used an RB harness and just redid a few of the lengths to be perfect. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted March 4 Author Share Posted March 4 I got my cnc intake and some parts back from media tumbling, it looks almost cast. I am super happy with the finish. Only issue it now shows finger prints. 1 Quote Link to comment Share on other sites More sharing options...

DuffyMahoney Posted March 6 Author Share Posted March 6 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. 1 Quote Link to comment Share on other sites More sharing options...

madkaw Posted April 5 Share Posted April 5 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. Quote Link to comment Share on other sites More sharing options...

DuffyMahoney Posted May 3 Author Share Posted May 3 (edited) 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.

DuffyMahoney Posted May 5 Author Share Posted May 5 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.
