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 magnesium housing and from what I read its not the preferred one for my application.
I'm sure Glenn Yee is the man at modifying these pumps. If i was doing a street car he'd already have it. I've heard and seen from Bruce's book that the 964 pump will work and so will the 996 pump. I think the 996 might be overkill. Wanted to hear some personal experience. See what racers have done in the past. (IMG:style_emoticons/default/driving.gif) |

The later pumps are generally stronger physically and higher capacity. Some extra on the pressure side, and the 964/996 pumps, lots of extra on the scavenge side. Extra scavenge is always good, but it won't improve your oil pressure. Re: the pressure side, it's unclear to me even for a track/race engine why an early motor needs any more pressure side capacity than an early pump provides. If you are happy with your oil pressure, the engine should be getting what it needs.
Do keep in mind that these pumps are all old at this point. They don't tend to wear quickly unless exposed to debris, but it's worth having it gone through by someone who knows what to check. Oil pump rebuilding services like the one mentioned above can do that. |
