    Default do 93 prelude SI's have vtec?

    i got the h23a1 in my prelude and as far as i was concerned it doesnt have vtec, because it doesnt say it on the valve cover, and didnt see anything that looked liek a vtec solenoid. but i was looking for something that would look like a civic vtec solenoid. i was looking at one of those motor specs websites and it said they are vtec, so i was just asking are they vtec or not? after i seen that i went back and looked and seen a black thing by the dist. and figured that might be it. also dont think ive ever heard it kick in at whatever rpms its suppose to at.
