Just got a lude and need help

I just bought a 92si with a JDM H22a swap and a H23 transmission from some kid who lost his license. The car is a fixer-upper. Right after I bought it I got a new throw-out bearing installed and when I got it back VTEC wouldn't work. The engine revs to about 6.5k and doesn't kick over to VTEC. Also there is a nasty crunch/grind when you try the 2-3 shift. The transmission is basically new. The kid I bought it from said it was because the H22a engine and H23 tranny don't match up perfectly and the synchos don't match. Is he retarded or what can I do to fix this?

he is retarded, try a new master and slave cylinders before you go and replace the tranny.

On the vtec thing is the oil full, was the car warmed up all of the way and is the car only reving to 6500rpms

let me know all of them them things before I can answer you question about that.

yup. the trannies are interchangeable. do what mike said first.

when you said after vtec wouldn't work after you installed a new throw-out bearing, are you saying it was working with the old one?

2nd to 3rd grinding is sorta normal for a tranny off a H23a1(for being 15-11 yrs old). Worn syncros. Honda's tranny are known for grinding. Happends alot B series trannys and K. Just wondering,is it hard to get into 1st and reverse too?

Hopefully that SOB didn't give you the P14 since he did have a h23 tranny.

Vtec worked fine before the new throw-out bearing was put in. I've checked the oil, it was full. I let the car warm up all the way and it still didn't work. I know Vtec doesn't work unless your moving. How do you tell what kind of ECU is in your car?

make sure the VTEC solenoid and VTEC oil pressure sensors are connected. When doing a tranny swap, its nessecary to disconnect wires in that area and I wouldnt be suprised if they got disconnected, or cut.

I checked the wires that were connected to the vtec solenoid and they all looked fine. There is plenty of oil. I tried disconnecting all the wires connected to the vtec solenoid and disconnecting the battery to reset the ecu but it didn't do anything.
