I have a stock b18c1 with a Full-race turbo manifold, precision sc54 turbo, full 3" exhaust (including dp), and probably most importantly - a skunk2 intake manifold.

Now I'm running uberdata and was wondering what I should set my vtec engagement point to. Can you guys give advice other then "go to the dyno"? I have a wideband o2 sensor I'm working on hooking up, but I doubt that'll help me.

really depends on the tuning. You need to get on a dyno and tune the vtec point according to your power curve

correct.. ive always had my vtec engagement point at about 5k rpms.. havent seen a dyno yet but i know from research a lot of people say raise higher than the stock 4400

does anybody have parts like this and have played with their vtec on a dyno? anyone know from dyno experience?

I'd use the butt dyno for this... theoretically, you should set it where the torque curves of both cams overlap. This is best for "area under the curve", but its way more fun to set it a bit higher so that you get a nice kick in the behind when VTEC engages!

Lots consider 4800-5000rpm to start out with. Across the board..
