Good Thread.

Go with the HX40 on that 2.3L Spools very quick as it is. Also, you're gonna want to make sure you follow the Holset's specs for installation. The off the shelf drain tube kits are way too small. (14mm). Holset requires at minimum 19mm ID. I modified a drain tube from a 2001 Cummins Dodge Ram, used -16AN Pushlock hose to slip over it, and welded a nipple on my oil pan in the factory spot.
