(6) Titanium Connecting rods and (5) bearings that came out of a Porsche 2.5L long stroke engine that are in good shape and individually weight 14.25oz. They were mounted onto a 2.4/2.7 Porsche crank. I had decided not to rebuild the engine they came out of that was not in use for 20+ yrs. Looking to build a high revving hot rod engine or race engine, these are your rods. Message me if you have any further questions about the rods.

A bump for today
These rods come really close to automotive art, IMO. If for no other reason than an engineering standpoint. Are these the same rods used on 917 engines? Honest - I'm tempted, even though I have no immediate need. I've heard the requisite bearings are ungodly expensive, however. Like $100 (US) per half shell. Anyone care to confirm/deny? Thanks.

You're right, these rods are mechanical porn! And you're also right bearings are hard to find. There are several used set of bearings advertised on Ebay right now. I think you can get them re coated with bearing material.
I also know that Freisinger had some remanufactured by Glyco, but then, you will have to sell your house/kids/organs to buy a set of them... Even if I don't exactly know what he asks for them, but he is usually not very wallet-friendly (nor friendly at all...)
Those rods have been fully polished, you don't even see the part numbers anymore, unless there is somthing I don't know about this model.

Do these rods utilize the 'U' shape saddle bearings like the 906 motors? I forget when the change was made from a special bearing to handle the thrust wear to just plasma coating Moly on the Ti itself and a normal bearing is used.
Of the folks I know who do the 'high end' stuff, they pick through their 'saddle' bearing collections and get them dry film coated. I'm told its a good enough solution for anything but running 24 hr endurance.
Ive never seen a bearing metal recoated, but that would be a neat solution. Maybe some sort of plasma spray method?
The big deal with Ti is getting them the shot peen treatment to deal with the fatigue life before reusing. The aero industry does this a lot and its all called out in a spec. IIRC, the process once complete recertifiys for 90ish% of the original new part lifetime.

The rods have a shadow from the saddle bearings it looks like.

Yes, these rods do use a "U" shaped bearing. Bearing are few and far between but there are a couple select people out there that own some. Knowing that, asking price for new bearings isn't cheap. Currently I have 5 of 6 bearings needed for the rods (someone cleaned the work bench off without realizing what was there). As for endurance racing, these rods came out of a Wayne Baker built 2.5L twin plug engine from the late 70's built for the 24hrs of Daytona. The engine was sent as a backup engine, never saw competitive racing only street use and the occasional POC and PCA event. There was a recent article in one of the Porsche magazines that talked about Pauter Racing machining these rods to accept NASCAS style bearings. I haven't personally seen the article but I was told of it.
These are pure mechanical porn. It would be awesome to see them go into someones engine build but they are equally as cool just resting on ones desk as a form of eye candy.
Just a bump
