I was thinking the ESS twin-screw units would be best for forced induction on an E53 due to their low-end torque production vs a centrifugal charger like Vortech.

I was looking for a kit daily for a while on ebay but forgot to look one day, and bam, there it was, a minty looking kit, sold in about 6 hours. Discouraged, I haven't looked much after that.

This would go on my 5MT with headers and EU2 tune, which already is a VERY nice combination.
