yungtuner

i swapped in my d16z6, and just got my vafc wired up. The guy i bought the engine from said vtec kicked in hard, and he could hear it, said it was pretty loud. i dont hear it. i can tell a difference from when it engages at 7k and at 5k, so i know its working, but is it not working right or something, or is it ok that i dont hear it. just making sure everything is ok before i put the turbo on.

you cant hear SOHC's really well. the guy lied to you.

agreed single cam Vtecs are tough to hear on engaugement (since the intake valves are getting the extra duration/lift) take off your air-filter and go drive around the block and listen carefully, you will hear it. Or, dissconnect your vtec solinoid and go drive around the block, it will feel really ----- on the top end.

Even dohc B-series are tough to hear once you put a turbo on.
