Having built and owned many turbo cars, I far prefer twins over single and intercooled over not but that's up to you.
Depending on what cam you have you may not need to change it.
Even if the specs were OK for boost(I don't know that they aren't) I wouldn't mind taming the cam down and lean a little more on the turbo to make the power. Its around 275@.050 and .640 at the retainer IIRC, I imagine that could be toned down a bit with forced induction and still make decent power.
