FYI, either vg30 install this drive gear different or the instructions you download to do this replacement are wrong. I have been trying to start my car for 3 days now. Finally brought over some AEM guys and we figured out for some reason my coil phasing was 180 out. Once we redid the phasing, the car started right up. It wasn't till i cam across a pic on the internet of a rb26 cam did I realize that even after very closely following the instruction for the gear install, I installed it backwards (180 degrees out). Now either the VG30 install is different or the instruction are wrong.
I did specifically ask the sales rep when i ordered this if there was any difference between the vg and the rb and he said no they are identical.
