aus jd 2703":23184b5a said:gen 3-4 are very similar in oiling. yes you could make a moroso pan work, but you would have to swap oil coolers make custom lines etc and in all honesty the gen 3-4 is a much better design.
No, it wont work
To use a Moroso sump on a gen4 you'll need to use a gen2 or 5S oil pump. You cant use one of those as crank pos sensor is mounted on the gen4 oil pump, and wont fit the gen2 of 5S pump.
As said though, there is no need to use the Moroso sump on a gen3 or gen4 at all.
They already have very good sumps.
