Just bought a 97 ek hatch with a b16 swap, it always hit VTEC at around 6000 rpms. I had the car checked out and I have a low pressure point in the fuel system. Could this be causing it to engage late?

Um. What? Be glad VTEC activates.

People I've talked to have told me that its a bit late and it should be engaging at around 5K, I was just wondering if it really should be around there and if so what I need to do.

That would be something I would have googled first. B16a VTEC crossover point.

As grumble mentioned, google that stuff...

Most B16A2's should engage around 5600RPM, are you sure your tac is functioning properly?
Also, what is your gauge for vtec engaging? butt dyno/readings aren't accurate.

Alright, thanks for the help. i'm new to all this and figured i'd ask here instead of wikipedia

You'd be surprised, wikipedia has some good information for Honda engines

I heard vtec kicks in around 3k.....but thats when some idiot decides to engage it manually thinking it would be cool

that's normal Larrskate, mine engage a little bit less than 6k with the oem gauge, which I suppose will be around 5600 and 5900

VTEC engagement point depends on the ECU. A 97 "EK" hatch means he probably has a JDM B16 ECU or chipped ECU with a 6k crossover.

USDM 99-00 Si ECUs have VTEC set around 5600RPM. JDM ones have it set closer to 6k RPM.

Also, what does "low pressure point in the fuel system" mean? By "checked out the fuel system" do you mean "I did not check anything really?"

PCT ECU crossover is 6200. Like everyone said check your ECU specs or if it is chipped. Either way it doesnt sound like a serious problem. But you can always clean the solenoid and change your oil.
