Need /4 oil pump and pressure line advice, Need to plumb oil to turbo--how?? Options

[Mueller]

I am rebuilding my motor for a turbocharger.

The motor will be using the stock cam so my RPM redline will remain the same as that on a stock normally asperiated motor.

1) Should I replace the stock oil pump?

2) If so, with which one?

3) Will non-stock pump need to be modified?


I need a constant oil flow for the bearings of the turbo.

4) What are my options for getting this oil?

5) Can I plumb into the oil pump?

6) Is there a place on the block I can tap into for the oil?


Thanks,

Mike

Standard aircooled vw turbo oiling:

Oil in: Replace oil pressure sender with a 'T' fitting on a short extension. Use a grease-gun hose to remotely locate the pressure sender. Use another grease-gun hose to plumb oil to the turbo. Don't hard-mount the sender to the T - virbation due to the pendulum effect may eventually crack something. If the grease-gun hose doesn't get you all the way to the turbo use some hard-line for part of the run.

Oil out: Return the oil to the engine via a valve cover or tap the block where a mechanical fuel pump would be located. Use heater-hose.

I have reservations regarding dumping the oil into the side of a tuna can. I don't think it's a good idea because that puts the end of the oil return hose submerged in the sump oil. That leaves just the volume of the hose for containing the flow of frothed up oil. Better IMHO to dump the oil out of the return hose into an open expanse (valve cover or sump above oil level) so it doesn't get backed up in the hose. Dumping into the side of the tuna-can would be fine if you were pushing it in with a pump (I've heard of a few people useing a Holly fuel pump for this purpose with sucess). But for gravity-feed oil return you need to dump it into an area without restriction.
