i have 2000 civic si with b20 vtec .it has wiseco 84mm 10.4-1 pistons and eagle rods .also a all new complete stock redone head. so my problem is that it was running very strong and everything was great and today i went for a drive and it wont rev past 6700 rpm , also i dont think the vtec is even engadging. please help!

there are a lot of things that can make vtec not work....

oil level too low, and a loose wire would seem to be the most common.... if you search you will find your answer im sure

yea bro just keep searching cuz even the slights bad connection on the vtec wire would throw it off not going past 6700. check if the wires r lose at the sensors cuz i had that problem on my R. they seemed they got pulled out of the sensor
