Might be out of most people's budget but this isn't a fox body or civic ride. So you either pay, go boost, sick with what you got and be happy.

We have 2 tb's that are already a nice size, talking about bigger ones will yield more power up top maybe but it will kill low end by reducing velocity. Everyone seems to think bigger tb's will make power, the manifold will get put into a cad and check for flow, if they are restrictive then they will be replaced. If they arent then the manifold will maximize air velocoity and make gains. Obviously its only na but 15-20 hp through the power band isnt unrealistic. People are sitting at like 336. 350zs made 312 ish with a manifold of the same design. The vq will benefit from this and I know some of you guys are running a little higher redline so you will see power up top.
I already talked to my shop and all of these gains are with supporting mods, long tube headers being a big factor
