Why are you wanting to add a supercharger if you want to run low boost? Have you looked into more cost efficent power adders? With a 96 gt you can gain a huge amount of power just adding heads,cams, and intake manifold. Try modularheadshop.com, you can get a stage 2 head and cam combo for around $1700. Its a lot less money wise then a blower and you gain a great deal of power. Upsides include the motor still retainings its stock functionality well adding that cool cam lobe sound. Granted it wont be as powerful as the SC but it does have its upsides when it comes to the money.
