I made a custom inlet for the gtm stage 1 sc housing. the intent was to copy the stage 1.5 and stage 2 intake to make more boost. I had a billet adapter made that bolts directly up to the housing. Which from there you can add a straight 3.5 or even 4" intake pipe and filter. Granted you will need a motor mount to give you clearance.
Attached is the SC inlet adapter (2.75" id) & a billet mount I had made.
