I got some realllll bad news for everyone lol. I actually contacted chris via instagram, and he was willing to help with the information. I told him we were all wondering what these part numbers were and off of what transmission from a ford did he find the synchro’s. Heres what he told me :” They were custom synchros I had lined. The idea came from our abuse of the 350/370 trans in road racing. Tremec made carbon lined ones for the T56,TKO, and 6060 transmissions. The issue with us building them was an OEM box was only 1400 at the time and on the shelf. Just a run of the liners for the synchros was 30k. We made two runs when APR was footing the bill and I kept several sets after they sold off the Nissans and went to the KiA“
And then he stated “ Sadly the cases flex to much to even make it worth while. The OEM stuff is good, but a billet case is needed to make anything last. I never looked into making one from billet, we welded some gussets in some to test and never got it tested.”
I found the exact gear that he posted on this thread. Its a carbon lined TKO 500-600 synchro gear from synch tech transmissions.
Heres what i was thinking and how to go about getting better synchros. My first option is getting a 370z synchro and having it cyro treated. All the gears/shafts i want to be cyro treated as well. The 300zx looks super close to the 370z trans so i want to order one ring and see if the ring works with the gear set. Obviously the teeth have to match. Also they make a carbon synchro ring for the F51 trans which i will try buying 1 synchro and seeing if that works as well. If all of this doesnt work then ill just stick to the cyro treated option. Its super weird that they dont make any CD009 carbon synchro rings. I will contact sync tech and ask them if they plan on or have any carbon lined synchro rings for the CD009 or JK.
Sorry for the bad news fellas!
