Your only option is to use a supercoupe 3.8l oil pump. it has one more tooth on the gears then the regular 3.8/4.2 oil pump and is suspected of flowing 13% more oil at the same pressures.

In my opinion you don't need it. stock oil pumps have been tried and true for every application out there even 500rwhp v6's.

well the one i ordered is the same part # the 3.8 supercoupes use. it looks like it will replace any 3.8 or 4.2 oil pump. still waiting for it to arrive.

I might be wrong, but I though the supercoupes had larger oil pans...the higher pressure pumps do a great job of pumping oil tothe TOP of the engine and the bottom end can run DRY...ouch!!
My friend put on on a Corvette ans spun a main bearing at 6500 rpm....no oil.

The high pressure pumps are for the racers with the big oil pans...stock oil pumps are fine for most other use...
