        Very early DTR models, 88 I believe, ran a slightly bigger bore cylinder, coded 3BN.

        Many DTRs ran a restricted 3BN head.

        DTREs ran 3MB head & barrels.

        The RE engine ran a different crank, stator and fly wheel cover.

        Early DTRs had a different oil pump.

          Some 3bn engines have slightly different inlets, not where the manifold bolts on but inside. The internals have different dimensions that I can only guess is supposed to help flow to the ports...
