F23 swap in Gen 5
#11
1997 Honda Accord SE with a JDM F23 VTEC swap. Running the P0H-L51 ecu. Engine seems to lose all power at about 4500 then acts like there's a rev limiter at 5500. No CELs! VTEC is not engaging I don't think. Any thoughts?

My moms car had an issue kinda like that at high speeds. I cant remember exactly what it was though. I think something as simple as a spark plug or something. Try going through the ignition system. If its swapped id check the ECU too, you may have a bad chip or ecu
This should also be in its own thread.

It does sound like the VTEC's not kicking in. Your ECU should have only one wire for the VTEC; for the solenoid. Download a factory service manual if you don't have one and troubleshoot. It's pretty easy as long as you have a DVM.

Your B2 manifold doesn't have fuel injection air (FIA) but the F23 cylinder head does. Since you're using a manifold without FIA on a head with FIA, is it possible that the F23 cylinder head has FIA holes that are open to atmosphere, creating a giant vacuum leak?
IDK for sure because I kept the F23 manifold on the F23 engine. Some pics of FIA manifold/head/gaskets here:
