folks, i have being following turbo mods on e34 particularly jonK's journey.

i'm interested in mounting an intercooler (what will fit and still allows me to use the aux fan and air-cond) to get the benefit of colder (denser) air.

however i have the following questions:
1. anyone tried that before?
2. would the intercooler have restriction on the airflow (i assume turboed cars can just 'force' the air thru)
3. what intercooler will fit my needs.
