Start with the exhaust system measurement of the 3.2.

Calculate the diameter you'll need for an optimal airflow at max rpm. Check header length. You'll be surprised. Same to the intake. And important - take a look at the heads.
Bad / good news - i don't know no correctly dimensioned after market solution right now - they all build the same crap.
But hey, i don't know nothing. Maybe i should install a patented underdrive pulley.
