4d55 Oil Pump quick question

[BradMph]

Well, I am not a diesel guy, but the G63B and 4G63 all have interchangeable parts but for some upgrades like the oil pump. The later years had bigger pumps, but these oil pumps also were interchangeable as well for the older model and considered an upgrade. Now for the diesel, you might try doing a parts search, for example on RockAuto and see what years specifically the item you need is compared to the years. Most the time they will post the years that the part will fit on and possibly this could help in your case. Most the time the blocks stayed the same, they just made upgrades on the external items and heads. Though the G63B 4G63 did have 2 size blocks by 1 inch larger which was a strange thing to do at Mitsubishi. Something about it wouldn't fit into an engine bay sideways when front wheel drive came around.
