EFI is the way to go, with the throttle before the s/c intake. The toyota superchares wil work sweet with efi, (as above) but shit with a carby setup.(Btw dont go blow-through, its really hard to get tuned right). If you can, try find a differnt s/c, the toyota ones are actually pretty shit, inefficient and produce a lot of heat. Personally i think a suck through supercharger would be the sweetest, not the most effective, but definatly looks the coolect and goes with the oldschool theme. Theres a couple of companys that make some nice suck through s/c's for 4 cyclinders. Some of the harley davidson s/c would suit you well, they look really cool(roots sytle) and come up on trademe every now and then.
