-6 Oil Pump Suggestions, For racing Options

[Jetsetsurfshop]

I've been get some parts together to start assembly of my 2.7 7R case engine and the oil pump needs to be bought.
The stock one looks ok and may work perfectly fine. I just don't want a problem both oiling and have to split the case to swap pumps.(or damage expense stuff)
The local Porsche dealer said the replacement pump is the 911-107-008-05. Some limited reading I can find on the web says that later pumps will fit too.
Any pros and cons that anyone is aware of doing the later pumps?
Thanks id advance (IMG:style_emoticons/default/beerchug.gif)

It’s a combination of pressure and volume

Too much pressure through a front cooler causes the oil to move through the cooler too fast for maximum efficiency

I had a long conversation with the engineers at fluidyne
I run a brand new 3.2 pump in my 2.0/6

Yeah that's an interesting point about flow through a cooler and the impact on cooling efficiency. I don't have a opinion on that, but from the arguments I've seen, it appears that there isn't exactly consensus on it.

More scavenging is generally considered a good thing. (Note that on 911 motors, auxiliary coolers are in the scavenge circuit.) For what it's worth, Porsche has put large pumps (with large scavenge sections) on its racecars and the later model street cars too, so there's that to consider.

Meanwhile, on my 2.7 race motor, I have a standard early mag pump and always got 70-75 psi.
