it all comes down to the fundamentals of the design etc of the core as to wether an intercooler will work or not.
in saying that , it is a common misconception that bigger is better.
more often than not a greater thickness of the core is required when the face (surface area of the core) is small.
i am of the opinion that hybrid coolers suck , though im sure many upon many guys have them on cars producing 350 at the treads, which is their choice i geuss.
remember that just because a cooler "flows" 500cfm , doesnt mean it will work , the way a cooler should. i mean a peice of down pipe from ur gutter flows 500cfm but does it cool air.
if i was you , and judging by ur car and engine combo i wouldnt skimp in any area of its build up , go and buy a cooler and or a kit from www.are.com.au , i am biased towards that company as i have known the owner for a good 13-14 odd years now, and have seen numerous back to back tests and logging etc of various coolers, and also have one on my vl
in other words , 400$ for a new cooler , no way , go spend that 400 on alcohol and waste ur money on something u will enjoy
