106 Intake centerline. I'm trying for 107, 110,
I ordered an adjustable gear out of Japan this morning. If I can pinpoint a couple settings that work on the dyno, I can drill stock gears to match what the adjustable gear is set to very easily, so I don't even have to use a bushing.
I also plan on modifying a "fixed" timing chain tensioner, given how short our races are. That would allow us to try cam timing changes on the course in a matter of minutes.
Isn't the Nismo gear a modified stock gear? Assumptions are a dangerous thing. The big problem is that we don't know who is modifying them, and how many people/shops are doing it.
All of this is required due to the radical cam I'm playing with. The guys at Schneider Cams said it was the most extreme 4 cylinder cam design they've ever ground, which means it had to be ground off-center from a normal grind to provide enough meat for the lobes without running out of hardened material. I'll have to break it in with light valve springs, then install something a little stiffer to be able to sustain the high rpms I need without valve float. I'm pretty sure 225 over the nose isn't going to cut it.
