i was just wondering, would the installation of an intercooler be the same on a 1g and galant vr4? since they're basically the same but i know they have different interoolers and location.

Totally different animals!!

The pipe routing, radiator location, front bumper, everything is different. If you're asking this question I'd highly suggest saving your pennies and buying a put together kit made precisely for the Galant.

Check out GalantVR4.comand do some searching for info relating to a FMIC.

Good luck,
