hello guys, so im trying to do an ls vtec conversion but i have some concerns about my intake manifold sensors. To start off i have a 1996 acura integra ls obviously bone stock and a 1991 b16 sir vtec head with 1998 itr intake manifold and sensors, the concern that i have is that my ls intake manifold has and extra sensor i believe its a vacum sensor or something since the hose its connected to the vacum receiver can ill show pictures. and the itr manifold doesn't have the same hole so i can put it in, do i have to cancel that sensor or i have to drill in a new hole to put that sensor in the itr manifold? im new into the honda scene and this is my first project so im trying to do it the right way any help would be much appreciated thank you guys

 

HELP!!!!

 

The vacuum line with the sensor attached should be re-directed to the nipple on the throttle body. It doesn't look like the tb you are using has that nipple.

You could just put a plug in the line or hook it up to another vacuum source nearby.

The nipple next to the map sensor in the pic is what I am talking about.

 

You don't have the port because your using Different OBD era parts in your build. As was said about, just source vacum for it from another location and call it a day. If you don't feel like fabbing anything yourself, just get a distribution block so you have ample ports for all your vacum hookups.

 

Also if you are really very new to Hondas, a hybrid might not be the best route for your first build. They are not as straight forward as a straight up B series VTEC Honda engine and if not done properly you will end up with an engine that quits on you after a few oil changes. If your definately going forward with a hybrid build, make sure you read some of the more detailed LSV threads here on HT and follow the advice to a T. One easily overlooked mistake can trash your entire build. Good luck!
