Ok i have an update but the problem is not solved yet. Up until now we have done the following things:changed the spark plugs
changed the map sensor
check the timing
changed the AEM
check the pipes
checked the vtec valve
checked connections
checked oil pressure
Nothing yet, all the above are working great
The vtec is not working, when the car goes on vtec it misfires, it refuses to work. The motor looks healthy as until vtec it gives no signs of misfunctioning, no strange sounds or anything, the vtec though doesn't work no matter where we put it (rpms wise) to engage.Tommorow, we are putting OEM injectors, OEM ECU and we will run it NA to see if the vtec engages. If not, we will remove the headgasket, so we can see if that is the case.
The car doesn't have an oil leak, it was my mistake because the oil was very new and clean and i couldn't read the dipstick good.
If you have any suggestions please share because i am starting to get frustrated

did this problem start after removing the cams? when you did the arp studs? you maye have had a few of the vtec pins fall out. another guy on the under the hood forum is having this same problem. vtec pins had fallen out of a rocker, maybe a few. hes still working on it. need to look real close so your not chasing your tail. if all alse looks good, take the cams and rockers out, make sure every pin is in place. also adjust the valves sweet make sure they arent too tight. let us know. later dave
whats interesting is that it will occasionally hit vtec, then other times it wont... and backfire and just all around not work when its supposed to switch cams...
i found a pin that had fallen out of the rocker arms... the car is currently getting worked on, as i couldnt get the chain tensioner out myself...
defintely check those rocker arms for the pins!

Guys i am going crazy here. I don't know what is happening. Today we put OEM injectors, OEM map and OEM ECU and the car still won't go into vtec. Then we opened the motor, we checked the vtec pins and timing and headgasket and everything is fine. Then we removed the exhaust from the downpipe until the muffler (so that there are no restrictions) and the car is still not go into vtec.
Next step is to remove the turbo and manifold and put the OEM header to see if the problem is with the turbo. We don't really know what else to try )

all of the vacuum lines hooked up? none are cracked or going to the wrong place? your map sensor is reading accurately and hasn't gone bad? idk, im not to knowledgeable on the subject matter, but those 2 caused problems for me in my NA celica when switching to high cam before.
