just picked up a 96 240 with an s15 sr20 swap, basically stock minus the front mount, tubular manifold, bov, etc.

what's the max boost i can run with the stock BB t28, and how much power can it safely hold?

also, what's the best oil to run in these motors, im use to running 20w50 with lucas in my mustangs..

any imput would be great, thanks...
