i have posted this in the stock engine forum and no one would answer me someone told me to do a serch but i dont know where to serech. I have a 92 ls and i have a 98 ls head i know that the 98 ls head will bolt on my question is i have the 98 IM will plug in to all of my sensors
thanks
The IACV will plug in fine, but if you are using the B18B TB you’ll have to either extend your map sensor harness to mate to the map sensor on top of the TB, run a hose from the 98 TB to your G2 map sensor, or use your G2 TB. You will definitely need to use your Injectors. The only other issue is the PCV system. The PCV valve on the OBD-2 LS Tegs goes from the intake manifold to the valve cover. On G2 Tegs it runs from the Intake manifold, to a junction that sits in the intake manifold between runners 4 & 3, and finally runs to a oil sperator box. So you either need a 96 up valve cover, or you’ll have to insert the “junction” hose into the 98 Intake manifold. Hope this helps.

Another option is to run a vacuum source from the manifold to the G2 MAP and leave the MAP on the B18B TB open. That’s what I’m currently doing even though it looks kinda funny not being plugged to anything.
well i dont have the 98 TB i have to use the 92 TB
