Dear All,
Problem: B16A2 + Sk2St2 = big dip at vtec xover.
Cam tuning, emanage, etc: still a problem.
Are there any baseline settings for the Sk2St2 timing-wise?
What about ignition?
+10 degrees for the whole spectrum?
Thanks,
B.

get a vafc and get to the dyno.
turn the engagement all the way down, dyno it.
turn the engagement all the way up, dyno it.
Where the two graphs of the low lobes start to fall and the high lobes start to rise will determine the best vtec crossover point.

High comperssion is a good idea for you to consider. these cams have more potential but you have to extract it all out by have an good intake and exhaust system, running a good EMS, and proper dyno tune. don't just slap it on and think it'll run right. time well spent at the dyno will award you with more speed. i would recommend you get some P30 or even PCT pistons, besure to check piston to valve clearance when installing high comp pistons.

Go to a dyno and tune the power curve. Don't just get peak power, try to scavenge the powerband all across the board. adjust cam timing bit by bit and also tune your ignition timing too. this will propably helps those cams better. besure that the valves dont hit the pistons.

as a base line, consider this:
cam gears:
I: -1
E: +2
VTEC x-over: 5700
redline, 9000 (assuming you have valvetrain to hold these rpms)
if you're still dipping, raise the vtec some more. the vtec lobe on the skunks don't make any power until about 5600 ish...

leave the ignition alone. if you want to change it, get some management like uberdata or something. playing with the distributor is not the right way to do it.
5700 is about where the vtec lobe makes power. 6750 is a little high... but then again, you have low compression, so it very well may take that long to be usable.

True, the Stage2 pulls about 5700 while the stage 1 pulls at 5200. you're gonna have to wait for a few rpms before you can haul ass.
