Great thread! Thanks for taking the time to put this in one place and explain it to Si virgins like myself. This is on my list of "to do" mods but I have one question:
Why are two insulated gaskets needed? Is it because you cannot reuse the OEM fiber gasket that currently sits between the IM and TB? I understand you want to keep the TB (which receives hot coolant) isolated from the IM if you've installed the IMG, otherwise you'd be heating the IM via the TB, defeating the whole point of the IMG.
In other words I'm curious if you can just go IM:OEM TB Gasket:P2R Spacer:P2R Gasket:TB.
It's only a $20 difference, so I'm not concerned about that aspect but I want to figure out the reason behind the two-gasket method.
