hey im looking into an intercooler for my l67 swap buit be for i go any farther i want to find out how much they help out ???

I believe the expected HP is around 50, although it will depend on other mods as well.

There is a small increase from the intercooler alone, I think ZZP says 20 HP, just from the cooler, denser air. But the real gains come because the intercooler lets you drop pulley sizes/advance timing because it'* a KR fighter, and that yeilds gains of MUCH more.

I think you are referring to the S2 L67. Let'* keep in mind the readers that aren't quite "in the know" yet. S1 L67'* have proven to be nearly impossible to fit an intercooler to. The biggest obstacle on those motors is the fuel manifold/injector assembly, as the injector go into the manifold as opposed the the S2, which go through the cylinder head. There are work-arounds, I am sure. But from a cost-effective standpoint, S1'* are left in the cold

S2'*, on the other hand, have a few cooler kits available. But even those are somewhat pricey.

keith is talking about his S2 swap in his lumina.

Personally, I'd go with the intercooler that sits right between the SC and the LIM. It'* about an inch thick, and doesn't crowd up the engine bay.

I was designing something exactly like that about 4 years ago, but someone beat me to it. :P
