yeah so i have a 1998 acura integra gsr that i barely bought about 2 months ago and my vtec engaged at 4500, but after i replaced my water pump, timing belt and had my timing adjusted i noticed that my vtec now engages at 5400 rpm. so is this normal for a gsr?

Check your oil levels/change oilReset your ECUThose are the most common

you're getting it wrong there chief4400 is where the butterflies in the intake open up more5800 is where the third lobe on the cam is engaged-vtecthere is no point for a vtec engagement that is sooner unless you have forced induction or a good increase in displacement. it's about volumetric efficiency. it makes no point to switch to other lobe when you don't need the air you will just loose torque

thats were it should of normaly kicked in, the prevous owner must of had changed... VTEC is all caps =]

yes all is well.
