which ims bearing upgrade

Funny -that is cheating :-).
The trick as I said is to suggest a how-to w/o dismantling the engine. How can it be done as part of a normal IMSB replacement?

...I just bought a 2004 Boxster S and immediately shipped her to Jake Raby and Flat 6 Innovatons and had them install the "IMS Solution", which is a plain bearing fed by an oil line.

The service experience was spectacular.

Highly recommended.

Good luck.

From my perspective this is an awesome engineering solution providing the contact forces in the bearing work out. I asked Jake long ago and he assured there is plenty of margin, so this appears to be the best solution going. Perhaps "overkill", but if ever you wanted overkill, this is the place. And another key here is where the oil comes from...

Probably the only way this could be done would be to cut a channel outside the bearing race in the bearing flange.

It's all about tools and IMS shafts. I'm not going to do this so I'll fess up. A fairly simple, but expensive tool could be made to drill a couple of holes from the inside of the IMS to the outside of the IMS through the sprocket splitting the twin chain sprockets as I did with mine (see YouTube). Then a (preferably high temp Viton) sealed 8 dollar greased bearing can be installed which will last for well, the life of the car. Likely. The tool is the key, the rest is just a simple bearing replacement. As an aside, a sealed bearing (as opposed to an open bearing) keeps particulate contamination out of the races which is nearly instant death to the bearing. Keeping the grease in the bearing keeps it lubricated and alive. Porsche's error? They did not account for the sealed intermediate shaft delta pressure pulling or pushing oil across the bearing. Solution? Vent the shaft.
