Hey,
Just use the intake barb piece that connects the brake power booster to the intake manifold, on like a 22R-E or many other Toyota EFI intakes including a 4A-GE/4A-GZE engines found in MR2s and Corollas.
It bolts right onto the diff housing, then just use some rubber hose and route it up and safe. I will be doing this soon
I bet this could be done for less than $5.
