I prefer the early pan also, I would like one for my car.

So the changes are the "cloverleaf" mounted to the bottom of the pan with 4 bolts and above that the full screen cover.
Im going to check the PET now, but i guess I'll also ask, is this lower portion of the pan available from Porsche, does it have a PN? If not, it appears to be a very simple thing to make with sheet steel or aluminum and even easier to reproduce the full sump covering screen.
I would imagine that even later pans have the same boss's cast into the pan where you can simply drill and tap to mount the older parts to a newer pan. Im stating this because i think that early pan prices just doubled.......
EDIT: According to PET the "cloverleaf" is 928 107 139 04 and is listed as "insert for oil pan"
Screen is listed as "oil strainer" and is PN 928 107 147 10
I will call tomorrow to check on prices and availability for the above parts. UPDATE: cloverleaf is $22 and the mesh screen is $127
The pickup according to the PET appears to be a multi part unit as opposed to the very simple ones ive seen in GT engines.

the best way to acquire them is from a parts car....or just call Anderson..he has plenty lying around.... I got mine from an 82 parts car, but the pics are from my old 79 parts car
it all depends on what the 928 will be used for.....on a street driven 928....I wouldn't change it....or even the occasionally track driven on street tires.....but any type of real racing or track use...you MUST do something to the oiling system....accusumps work, but have their own issues....this is the best answer I have found for minimal cost....

Now if only someone could produce a very cheap (plastic stamped) windage tray system like those that appear on most all domestic V8's sometimes in the form of an integrated pan gasket/windage tray.
The IJ crank scraper looks like overkill for a street car, but I want the benefits of a windage tray in the bottom of the engine.

What do they run $ anyway?
and with the spacer, wouldnt you also want to space the oil pickup points 3/8" and perhaps cut down the oil level dipstick tube by the same 3/8" for a proper level?
The dipstick i could understand you not modifying as a knowledgeable owner would account for this with oil checks. But the oil pickup length seems to be a more serious issue.

nothing modifiied on any of my race cars. everything has and will be fine. Im even running on 305 and 335 size tires, A series hoosiers, running 1:36.1 times at laguna. the old engine had 110 race days and Ive just finished over a couple of years on the new stroker engine. no breather, no baffles, accusump, screens, nothing, spacer, nada.
Its very suspected that screens and windage trays, if not properly designed, can restrict flow back to the oiing system, which can lead to starvation.
Brian, you only lost an engine, due to one being suspect, and the other running 4 quarts low on oil.
scot has no issues. I beat the snot out of that thing after me building in 2 years ago for a 3 race weekend! never did anything but run like a champ, full oil pressure , all the time.
We use all the new oil pickup stuff.
amsoil ! and its always full .

I disagree that the early pick-up system is better. I've changed to the S4 pick-up and no cloverleaf and believe it is superior. There are 2 reasons:
#1) Under acceleration, the front of the cloverleaf will get exposed to air. Once the air is under the cloverleaf it has no where to go except into the engine. The S4 pick-up is closer to the pan floor and will suck oil longer than the cloverleaf in real use. "Real use" is when the car is accelerating and turning.
#2) The S4 pick-up has a screen. Once you've had to flush chucks from an oiling system you'll appreciate this simple fact.
And yes, I grenaded my 2/6 bearings with Amsoil and the original cloverleaf pick-up.
The 928s oiling issues are more complex than any simple fix will solve.
I have had excellent results with the full I-J windage system, with S4 pick-up and Amsoil.

my thoughts too.
I dont know what the symptoms of your bearing failure were, but it would be interesting to hear. high revs through sweepers, longer than 5-6 seconds? who did the rebuild? was it a rebuild? curious. So far, Ive been responsible for over 5 engines all racing more than most anyone here, with no issues, with no early warning symptoms. (i.e. low oil pressure around turns, stuff in oil filter, etc)
It might be luck of the bearings and clearances used. Ive been using glycol, but GB says that those are not very good anymore , and porsche is very expensive.
