Well for starters I believe you are only suppose to run up to 12psi on a smic. Even at this point you are not ver efficient because of the small turbo you have and the temp of the air entering the intake manifold. Its totaly possible, next you need to have a high pressure fuel pump, a walbro or a 300zxtt pump. Next you better be able to keep the engine cool, so a good radiator with a electric fan will be neccessary. If you go with a FMIC you can use the stock radiator but use the twinline electric fans, these work great. All these are things nessecary to run that type of boost and keep from breaking stuff. Of coarse you can ignore some of these things and run that kind of boost but that's at your own risk. Ohh yeah a clutch to match the power will be a must unless you don't care about slipping it.
