There is stock which is probably the weakest option. I take that back, the pelican kit that installs a single row bearing and spacer is my least favorite solution.
With no plain bearing ever going to happen, this leaves the roller bearing by EPS as sold by vertex or the LN dual row ceramic.
One thing I haven't noticed on any of the various porsche forums that i frequent is anyone saying either product had let them down. Also, when presented with the diagnoses for my metal filled engine Jake asked that i not use the LN bearing, and rightly so for someone wanting to protect a company reputation.
I don't know that anything I'm doing here would change his opinion. That said, the bearing is currently still available to the consumer and is easily the most confidence inspiring option available.
So far no one has called me for having all six connecting rods installed. In real life bank 1-3 rods have the piston attached and are pushed through the case and the rod caps done after. I really wanted to get a feel for how the parts fit. The entire thing is sitting at low torque..Ive decided to go in for a stretch gauge before exercising the new torque wrench i received for Christmas.

I also have a dual row bearing and on my second LN ceramic bearing and I added the TuneRS direct oil feed last year. Keep in mind that I drive my car a fair amount on the highway. I drive it like a Porsche was meant to be driven and I am at around 166k on the odometer. I do know that TuneRS has been racing their cars for several years using this setup. Here is the link. Plus you can use either the LN bearing, EPS bearing or the steal bearing just like the original one supplied with the Direct Oil Feed kit. I might add that the original IMS was not the reason I had to rebuild my engine at about 116k miles. The 5th and 6th cylnders had oil deposits. Another reason why you never follow Porsche corporate / dealership advice for oil changes every 15k or 7500 miles. Special thanks to whoever owned my car first for that. Anyway that ordeal taught me a lot about my Boxster.
Lubrication has always been the problem. I thing the EPS sounds like a good idea but I would feel a lot more comfortable if more people shared their experience with the EPS before I were to consider it in when I decide to drop in a 3.2 or 3.4 in my Boxster. Here is the link for you to check it out.

I am looking forward to your progress on this thread because I want to do the same thing with a 3.2 or 3.4 to have ready when I hit 200 or 250k on the odometer
