Where did you buy your intercoolers (and where the piping)? I'd like to see them. I've been told it's a night and day thing with intercoolers, im leaning towards FMIC since it's nice and simple.
here is mine, its not installed yet, and will require relocation of the radiator(which I am putting on top of the motor under a cowl hood) to make it fit.
I know its a little big, but it is supposed to protect the G60 supercharger from the heat of the turbo.
as for the piping it is going to be 2 inch from the turbo to the intercooler, and 2.5 from the intercooler into the G60 and from the G60 to the ported gasser intake.
