What other intercoolers fit in 300tdi's?

hello to all
just a quick brain picker, has anybody any information about stock intercoolers from other cars, vans ect that are bigger than the standard 300tdi intercooler but will fit in front of the rad?? i need a more cold dense air into my system and need to go about the cheap way, not the £400 shiny new way, thanks for reading this Ian

No idea, but I'm all ears.

adn Im all figners and thmbus

yup definatly the way to go - any info out there?

Cheapest way is to use another 300 intercooler.

i have two intercooler rads in series but ive yet to try it...
