I am stuck on whether to get a loan for a Gxp or go intercooled and 3.2/3.3 pulley on my Gtp . . . any input would be great. ive noticed the GXP's seem to be out the ass expensive to see lower than stock 1/4 mile times, but would it be better to spend the money to get a GXP or spend half that to put my car into the low 13's?
