vtec on a gsr engages at 4400rpm...so dont go too high...and dont rev it too high, the ls rods are the weak point...but to set your vtec engagement point take it to a dyno and make a pull nonvtec...then for the next pull set vtec low like at 3000rpm...take the 2 graphs and find where the lines intersect and set vtec 100 rpms before that point

Basically right.
As for me: I rev to 8600-8700 (been tuned to 9200), and vtec engages at 5200. It's not a stock ls/vtec though.
