Oil feed line usage

[spyderdrifter]

I've looked around and haven't found the answer I'm searching for. I bought a 6 bolt long block yesterday, but I'm going to use my 7 bolt head instead of the 6 bolt head. My 6 bolt OFH has all the ports capped with threaded inserts since the original setup had the oil feed line hooked to the head. My 7 bolt head has this port on the head capped. Since the 6 bolt OFH is capped, I really don't want to mess with it, so if I use the feed port on the 7 bolt head, is there anything I have to do to the head for it to work right or is it ready as soon as I pull the plug from it?

Also, which of these ports is actually better for the turbo? I know the OFH port delivers direct oil unlike the head port, but the head port is a less complicated and shorter route to run.

Just remove that bolt/plug and you're golden.. As far as better for the turbo, it depends on which one. A MHI unit would be better off from the head since thats where the factory fed them. From the filter housing is also a higher pressure so you may need to use a restrictor.. Maybe.

I'm gonna be getting a 16G here within the next couple weeks if that makes any difference. I'm really wanting to have the feed come from the head as well. Does ExtremePSi sell the line for that location?

They might.. I bought this one from MAP when I fed my 20g from the head Turbo Oil Line Kit / DSM stock turbo - Modern Automotive Performance

Perfect, but looks kinda long. Thanks for the link.

2g awd evo 3 16g here .running my turbo oil feed from filter housing. Journal bearing turbos require higher oil pressure than bb turbos because the bearing floats on a thin film. Of oil . Just like rod or main bearings . Bb turbos have lower rotating friction because of ball bearings thus the use of a restrictor in the oil line. Oil pressure is higher at the ofh than the top of the head, common sense. Like I said i'm running e316g oil feed from filter for about 12k @25psi and I have as much shaft play as when it came out the box. On conventional oil.150k on the motor
