i put a mitsu evo8 turbo in my car, and afterwards, my vtec won't start working. first the redline went from 8200 to 5500, then i had the solenoid looked at. afterwards the seal was replaced, my redline went up to about 6500rpm. but the vtec still wont start.. my oil level is pretty high, and ive added more oil just to make sure it has enough. would there be anything else i should be checking?
