I have a B16A1 that i just swapped into a 91 civic, I was wondering how you can tell if your VTEC is kicking in, i cant hear any change in tone? What should happen different, should there be a big change in sound with this motor?

 

you will know when its on.

I have a B16A2 and the VTEC kicks in at 5600 rpm. It doesn't get louder, but the tone changes. If you have a stock intake, it's really hard to hear.

 

mine sounds like the world is comming to the end.

 

you are a damn funny fellow . . . you sounds funny in your every post and even your pic of the Homer Simson is funny

 

run a test light to the vtec wire and see if it is getting the signal!!

 

Take you intake hose off and go for a run around the block....You'll know hehehe

 

no dont do that!!

 

Mine kicks in at 5k w/stock pr3 why??????????????????

 

And yes im sure its at 5k rpm I watched it carefully and it does ....
