i made my intercooler from a truck intercooler, yes i know "how dodgy". ive had all my import mates telling me that they dont flow proply but i ran on the flow bench against a trust intercooler off my g/f brothers rx7 and it blem that out of the water. its 800x350x75 and it works awsome. pain in the ass to mont behind a standard front bar though, had to cut the thing to bits
