With some adventuring in local junkyards and the advice/wisdom of willwren, I am attempting to install a 92 aluminum upper intake onto my 94. This way I eliminate the possibility of warping a plastic intake and doing maybe even worse with sudden temperature changes due to nitrous. According to willwren its best to just block off the coolent passage to the TB which I could get all technical about, but it hurts my head. Bill can explain all that.
I'm just hoping the 92 and 94 lower intakes are identical, if not I may go grab a lower intake off a 92 L27 and see what can be done. Sadly this does not pertain to L36 drivers because of a much different intake system (just by comparing the L27 and L36 runners you can tell something doesn't quite match).
Also I will have to get the upper intake matched to my 94 TB because the 92 TB was slightly smaller and a custom gasket will have to be made by my retarded self.
In conclusion, if this all works out I believe it will be a breakthrough for us L27 plastic upper intake owners.
