a simple for a 4020 is a 4430 intake,exhaust and turbo--we have a 65 powershift with this setup dynoing 155--fun to work with BUT remember you still have a 90 hp radiator--try it.if you do set the tranny pump to 200 or more but not over 220--the filter bolts will stretch!! have fun

This^^^^^^^^^ or similiar. Don't mess around installing an old M&W kit. They aren't worth the time it takes to look at them, IMO.

We've done several, but all of them were very late models with the latest style intake manifold. (And late block casting) Because of that very late intake manifold, we could reuse that. We used boneyard parts from 4320 tractors. Drilled and tapped a hole in the cylinder block for the oil drain tube fitting to screw into. Put the hole right where it would be on a 4320. Looked factory when done, except for the air cleaner piping to the turbo air side. That we had to fab up.
