5200 RPM on my B16A Del Sol. Welcome to the wonderful world of torqueless engines.;)
Oops. You have the SOHC VTEC. I had one of those too on my 1994 Civic Si. I can't remember when it kicked in on that engine but it's nothing compared to the twincam models.

Its not noticable on the D16 as it is on a B18 or H22.

Id say if you dont feel it yet at 4500 rpm, go up to 6000!

not from a soch vtec si. Besides, gsr kicks in around 4500rpm, si isnt till like established around 5700rpm.
dohc vtec you will notice vtec compared to sohc.
