use a sc 12 off 1600 mr2/toyota, not sure what the injection system on the suzuki is but you may need to change the setup to a megasquirt or link or something, so you can up the fuel, setup would be reasonably simple if you are capable of mount and aligning pulley and making the plumbing and wiring changes to suit. you are probably better off to repower with a supercharged motor, regardless you will need certification if road going
Better off with a small responsive turbo imo. Better on fuel during daily driving too due to higher efficiency etc and you don't have to piss around with belts and pully sizes.
If you wanted to be basic about it you could run a standalone injector driver from jaycar or similar.
