I was wondering if there is a difference between a 13b Cosmo LIM and UIM vs the Standard America one? Can you swap a Standard one with a 13BCosmo one?

They aren't a direct swap! You would have to port match the intake ports, and fab something up between the TB and intake elbow, because the manifold is shorter than the standard REW manifold.

No not yet, Just working out some bugs. Just trying to get some tuning in but the weather has not been very nice here in ohio. The car has been in the bodyshop for months and i finally just got it back. I should have some numbers before the revolution. I'm hoping to gain some more top end by the size of the intake ports. They are huge. Overall drivabilty is just like normal. The only difficult part of the swap was hooking up the TPS. I'll try to post some numbers after winter breaks.
