Porsche part equivalent?

[NewArt1]

I am aware that Porsche sources many car parts from other brands: BMW, Audi, and VW to name 3. For instance, the lifters used in my 986 S are apparently the same as found in the BMW parts bin. My question is, does anyone know of a list or resource to find the equivalent part number? For example, the lifters at Porsche are part number 99610504172, so the corresponding BMW # would be .....
Thanks for any info you might have!

May I ask what the purpose of knowing this would be? Cost savings?

The valvetronic engines in bmws have valve lift control but it is controlled by an electric motor that changes valve lift by a lever system.

Where as porsche uses oil feed to lock a pin in their 2 stage lifters...

So they are completely different. not to say that there are other models that that would fit / cross reference

I think a parts comparison list like this will be unlikely or extremly hard to find. But if exists I would love to see it as well! :)

I think you will find more similarities in Audi / VW rather than bmw.

Cheers.

in this fantastically detailed post : http://forums.rennlist.com/rennforums/996-forum/644150-1-rebuilt-engine-1-month-and-325-pictures-later.html , Logray rebuilds his M96-01 and he mentions using BMW lifters from 4wheelsautoparts.com . These are less expensive than the equivalent porsche oem even though they are identical from the same oem supplier (apparently). I just thought that someone may have used equivalent parts in common repairs and would like to share the info.

Awesome! I will have to check that out.

I've just been schooled go renntech!

I notice that my 996 2003 expansion cap is the same as the one that was on my 1998 Golf.

IIRC, the heater blower for a 986 is a Valeo unit that is the same as the one found in a 1997 VW Jetta Wagon.

Lifters in question (for M96 2.5, 2.7 and 3.4 engines, not sure about 3.2's) are less than half price vs.OEM at www.eeuroparts.com last time I looked. Their part# is 11 32 1 748 884.

On recent 2.5 rebuild opted to try and re-use existing lifters. Worked well as I am having no issues with stuck lifter after almost 2k miles since rebuild. Trick is to make sure the nipple underneath compresses easily / freely. This indicates good lifter. Also check for excessive scoring up top and along the sides.

Yes, I see that the lifters are the same for the 3.2 as well. I plan to test all the existing lifters in the warm oil bath before I replace any. I was mostly curious to see if there were other parts which were common to other brands and if perhaps a list could be compiled by enthusiasts who like to tackle some rebuild/upgrade projects and keep the costs in line.
