Hey guys, so I have on 03 lq4 that I'm gonna put in my cts v. I am wanting to boost it and have a few questions. I would like to be in the 600-700 range. Now I want a supercharger but not sure if to get whipple, Maggie or procharger. Max boost on all these? Best reliability? Easiest to tune or repair? Also I got stock 317 heads, good for boost? Or ls3 heads?

With the CTS-V being a heavier car, I would lean toward a TVS or Whipple. Boost is boost. Tuning will be about the same. I would run LS3 heads with LS9 head gaskets and a stock LS3 intake manifold. If you plan on going past 12-15psi, I would use LSA heads as they are a much harder material than the LS3 heads and won't wiggle around under high boost like an LS3 head will.

So if I get ls3 manifold then does that mean procharger? Can I use ls9 gaskets on lsa heads?

Lol. I had a brain fart. If you do a centri you will need the LS3 manifold if you do LS3 or LSA heads. The LS9 head gaskets work on everything from a 4.8 to a 6.2 engine. I would personally do a TVS or Whipple on that car for a goal of 600-700rwhp. If you were shooting for 800+ I would say do a Procharger F1A or a Vortech YSi. Is your car a manual or auto? If it's an auto, you can do a centri and pair it with a good converter to make up for the centri having a bit less torque down low. In the end, anything you choose to add boost is going to be fun!

Lol it's all good. Alright so lsa and ls9 gaskets thanks. But yes it will be manual.

Oh and know a good place for lsa heads? Heard their real cheap
