Since converting to a 3.6 Varioram motor, I'm considering ducting the tub and going to a larger cooler that is sealed in front.
Any recommendations for brands or size?

I like the B&Bs, they have all the fittings on the passenger side end, either straight or 45*, -12 and are available in the following sizes
5.5x2.25x24
6x3x24
5.5x2.25x20
5.5x2.25x15
use the biggest one that has the closest shape to that of your inlet. definitely seal/duct it
For street use a single 5.5x2.25x24 has been fine on my cars on the hottest days and in what little traffic I drive in, for track use something bigger will be needed. I had to go to much larger dual Setrabs on my 3.8 993RS
