Well, not really, the only real disadvantage I can think of is boost drop.  All 

things being equal, the larger capacity IC will have a larger boost drop.  Not 

really a big deal since a good intercoolers may only have a 1/2 psi boost drop.  

Double the size of the IC and you won't see too much more than 1 psi drop.



Another serious problem with *big* intercooler occurs when they are mounted in 

front of the radiator-- overheating.  1.6 miatas are very prone to this.  Can 

easily be fixed by installating a more efficient radiator (Modine, etc,.)  1.8s 

seem to be less prone to overheating.
