... LS/Vtec=BIG thumbs down... if you need a reason why please feel free to search... as for the butterfly problem... one of two things can be done... pull the vacum line off the solinoid (sp?) and then they will stay open... or replace the manifold... also just so you know i would run a p72 or a p30 both have knock sensors...

The knock sensor is a very good sensor to have. It is basicly a microphone for the ecm to listen for detonation, or knock, and depending on the severity of it, retard the ignition timing accordingly to prevent engine damage. P28 and P72 have the same connections. The p72 is desirable because it is fairly easy to get, has vtec, and is easily chipped to run the b series vtec motors. You can get a p28 cheaper than a p72 in most cases.

well what if you have a P28 will it work or is it just a smart idea to plug and play a P72 and wire a knock sensor ?

The secondaries will stay open by default unless vacuum is suplied to the diaphram. If you remove the vacuume line from the diphram, just plug it up so you don't have a vacuum leak. When the rpm's reach 5750, the ecm turns off the iab solenoid and no longer supplies vacuum to the diaphram causing it to open. When the secondaries are closed, (vacuum suplied to diaphram), the intake path is longer and more narrow and aids in the production of more torque at lower rpms (below 5750). If you leave them open all the time, you may feel a slight decrease in power at lower rpms or a bog after vtec cross over. If I leave mine open all the time it bogs around 5000 to 5500 and as soon as it hits 6000 it takes off again. Although mine is a b16 block, the b18 may react different.
