well i wouldnt understand how one guys sohc vtec swap runs a 15.4 and mines can only muster a 16 second run.

Well to activate the vtec i am using a msd rpm switch and my i compression checked the motor and they all read 190.

when i first run my car its pretty fast and then when it heats up like after driving for more than an hour it'll run like crap.
