i disagree. the very first thing you should do for speed is an M50 intake manifold conversion from KOperformance (best price for whole kit). It has proven at least 10 rwhp on a 328. Then get the shark.
BTW, moving to car showroom.
BTWW: I LOVE YOUR CAR. so clean for a 96. exact same car as me except a 5-speed (smart bastard) and mine came with different wheels. good price for what it looks like you got.
