Thread: XPZ/Intense Stage 4 Heads

XPZ is smaller than the S3 and S4 and holds the current M90 record.

So you tell me.

Yeah have the xpz reason I went with it is because as stated above by Darkhorizon it's on top of the list for best powered gp on supercharged setups.
It wasn't cheap but I'm hoping the stage 4 heads will be a perfect fit for the xpz that's why. All I really need is major stuff heads Trans some harness/adapters for a swap and a tune that's about it.
beaides that I have everything as far as I know.

So saying I went the right route by going XPZ?

Yes.

If you can get a deal on S4 heads, they'll work very well with this cam.

You'll want ZZP headers for their larger primaries. But you're in CA, so TOGs is your only option there.

It would have to have a CARB approval number for his specific vehicle on it though.

Correct but at 900 bucks Because of a sticker I need ima hold off on it.
I have a carb number already from a friend that also lives in Cali for tog headers but I will be running my speed daddy's and just have the sticker on the car they won't know the difference.
