where's the oil supply

[72sat]

could someone please post some pics of the turbo oil supply from the head for a 420a,4g63,4g64.are they all the same?

4g64 and 420a is not turbo. Only 4g63t are turbo'ed and the oil supply is on the side of the head.

On the 4g63 6 bolt, the oil supply is in front of the thermostat housing on the side of the head. Correct me if I'm wrong, but I believe the 7 bolts get the oil from the OFH.

that is correct, 7 bolts get it from the Oil Filter Housing.

If you have a 7 bolt, attached is the how to for the turbo swap. About 3/4 downt the page, you will find a picture of the oil feed line where it meets the turbo, and then at the bottom or on page 2, you will see where the feed line meets the oil filter housing.

Not all of them- only the 2G 7-bolts have the oil supply sourced at the filter housing due to the additonal pressure and volume requirements of the Garrett T25 turbo. The oil drain line is also larger in diameter on 2G's in order to handle the additional volume of oil draining from the turbo.

so if I want to turbo my 4g64 where do I get an oil supply?

That hinges on the oil pressure and volume requirement for the turbo you're using; a question we can't really answer for you....but we can probably get you in the ballpark if you know what your oil pressure would be at various locations.
