550's and a fuel pump and you'll be dandy. Get a datalogger & see what p/w you're running on your injectors, I think you will be kicking yourself. Best to get a datalogger & make sure everything is ok when you're running above 15-17 psi on a smic. that supra smic is thick as a tree, but I still wouldn't even go past 15psi on a stock fuel pump.
fuel pump. injectors. datalogger. tune.
ooh, actually, you have a 1g, you're probably over-running your stock MAS, best get a 2g one or a maf-t setup...ahh, the fun, the fun. (by fun, I mean money)
