Well, it's good for the 928 world I don't have the funds to buy this since I would end up dropping in one of my spare 16V engines with a supercharger

Point of order. Those rods had nothing to do with your engine implosion right Rob?

For the humorless, this is me poking fun at Erik.

I've had a customer looking for a "great deal" on a stock low mileage 5 speed GTS for over a year....there doesn't seem to be a whole bunch of them out there.
I think that these cars have "hit bottom" and are becoming more and more desirable. I'm not sure how many 5 speed GTS cars were imported into the US, but I'm guessing that there's not enough to satisfy the demand. I "see" these cars being like the 356 "SC" models....which were virtually unobtainable by the 1980's....the same age as 928GTS vehicles are now.
Upgrading one of these cars to a 475hp stroker engine, while keeping it looking virtually stock, seems to create one hell of a vehicle. You need to spend well over 100K to get a current, comparable vehicle. I've built two GTS 5 speed models with stroker engines....and I don't think that 90K would buy either one.
While the pieces and the technology for the building of stroker 928 engines has come "light years" since this engine was built (thank God), there are still a whole bunch of good pieces left to build an engine from. Sure, an updated stroker engine will cost as much as the original build cost....but that is still 15K cheaper than starting from scratch....minimum!
It's interesting to look through the invoices for this engine. Most of the pieces, from Porsche, have doubled in price, in the 6 years since this engine was built. That 35K it took to build this engine is very close to 50K, today....just re-pricing the parts to current prices.
If you are looking for a "steal" on a stock low mileage GTS 5 speed...this isn't the car. If you are looking for the ability to build a "current technology" GTS 5 speed stroker....I'm not sure it will ever get any better than this deal. The math, if someone wants a stroked GTS, is almost silly if one looks at it from the "other" direction. If you get $15,000 worth of parts to build a stroker engine, you get a low mileage GTS 5 speed car for $12,500....which has a set of Devek Headers and one of his 3" exhaust systems. That's one hell of a deal...if you want to own one really nice hot rod!

Or just drop in a good used S-4 engine and sell the stroker bits ! No one would ever know the difference.
Hmm, (http://www.mailordercentral.com/928i...100%20940%2044) * 0.5. A 90-91 motor oughta be compatible with the ICM relay....

I've been working on Porsches my entire life. I've got every "technical" book that Porsche ever wrote. When Porsche writes "All of the connecting rods must be replaced if more than two of the rod nuts are loosened"....they didn't do that because they had run out of things to say.
While I'm sure that 150,000 miles here, in the US, is much different than 150,000 miles in Germany....those rods still need to be "retired", in almost anyone's book.

If the oil pump has gone bad, would that also mean that the block surface where the pump gears ride has been damaged too?
I think it would be better to just source another block and have it Nikasil coated for a stroker project. Or buy a new GTS short block from Porsche, I think they are still available.

While not easy, it is possible to "kiss" this surface and make it new, again.

Is that for all 928 engines?
Or just for s select few?
If it is for all, then I have to question the quality of the factory Porsche rods.
Hell that would mean that every time you replaced the rod bearings you would need new rods.
What was Porsche's train of thought on this Greg?
Any idea?
