Thanks everyone!
Jus my intercooler will be here next week, and its 700x300x150!

(Custom made, FAR bigger than most GTR intercoolers)
And i wondered how it compared to the RS500 one, which is a nice benchmark hooj intercooler.
500 ones are very tall, probably one of the highest car intercoolers there is!
Tho i guess its the thickness thats the thing with the 500 one, where it fits means it cant be v.thick
Always wondered if a proper front mounter would fit and be better (ie not so high, but wider and FAR thicker, esp as a lot of the RS500 intercooler isnt really exposed to well to the airflow...), like the WRC one.
Heres a pic of how big mine is (jus different end tanks on mine)-
