Im in the process of building a 98 gtp. i got the hole car stripped down, doors off, no hood on it, trunk lid, windsheild, everything to paint it. Im debating on what i should do motor wise. the car is stock and i already have a 3.4 pulley and a mechanic to tune the car. He also said he can modify the air box so i dont have to waste my time with intake right off the bat. He says the car can be tuned for the pulley even with just a few small things being. let me know what you think and what mods i can do.
