There are lots of one-off home-brewed fixes. Only problem is each has a specific theory of operation and claim for excellence which is not backed up with enough varied user experiences to form any statistical basis for the claims. They may be right, they may be wrong. Some other kits have 10+ installs, others hundreds. Those you start to see enough posts on (or more specifically lack of posts about complete with curses) to start to have some confidence in.

Since the installer's experience, training, tools and ethics matter, I'd do as much research on the installer as I would on the kit assuming I was paying for the install.

Duezzer I see that you installed the EMS IMS back in 2014 can you report how the car is doing with this bearing I'm thinking of going this route and wanted some feedback. I can't find any reviews on it.

Just an observation from a guy who specified an LN bearing to be installed in a donor engine after mine died from IMS failure. Make sure you specify the PRO version of the bearing or youi might get the Classic, which LN still makes avaiable to distributors as a special order. The Classic is rated for only 2/3 the service life of the Pro. A big deal particualarly if your car is a tip and your don't want to pull the tranny more often than absolutely necessary as it's significantly more $ to pull the tip. Just learned this lesson the hard way

Absolutely

You should do research on who your installer is and their experience as well as listen to his recommendations. Then go do research on the varying options and their costs. Then go back and discuss briefly with your installer asking what experience with that specific SKU he has, what tolls he uses and whose instructions. All these things matter.

Often there could be ten choices depending on which bearing is found to be original to the engine. Take your choice.

There are several roller bearing options. Another is Roller Bearing IMS Retrofit Kit – RND Engines

Vertex auto installs them in all of their rebuilt engines they sell. Logic says that if they were eating failed engines they would certainly switch to something else.......
Hi actCG.

Thanks for bringing this to our attention. We apologize for not responding to these threads earlier, but we appreciate your feedback. We have been focusing on improving our current EPS line and further developing some very exciting new products, which is one of the primary reasons why we have not been active here.



Now here we are! Here are some answers to your questions. Regarding our product, we are definitely proud of it! Since we started to sell our EPS Patented Cylindrical IMS Bearing since 2013, we have sold 5,000 units in total, and we have NOT had a report of a single failure.


The reason why our IMS Cylindrical Bearing does not fail is because it is made of a completely different technology than the traditional ball bearing at Porsche and LN. The reason for the IMS failure is due to the type of bearing that is employed. LN and Porsche use a ball bearing that applies the load on a single point of about 1.0mm. Our EPS Cylindrical bearing spreads out the pressure point, applying the load on approximately 15mm. To give you a little reference on how the ball bearing is inferior to the cylindrical bearing, you can take a look at Porsche’s attempt to correct the IMS problem throughout the years. Porsche changed the ball bearing 3 different times. First, a single row of 47mm, then a double row of 47mm, and finally a single row of 62mm. All three bearings failed.

Here is a little spec information. The IMS shaft turns at HALF the speed of the engine (max 3,500 RPM). Our EPS IMS Cylindrical bearings can operate at speeds up 15,000 RPM. The speed that the IMS bearing is operating originally at (max 3,500) is a leisurely pace compared to its ability of 15,000 RPM.

Regarding your question about the oil lubrication being the problem, this is not the case. The bearing is positioned at the bottom of the oil pan, so it is essentially submerged in oil at all times. Lubrication is not the problem here.



We look forward to getting in touch in the future. If you have any questions, please feel free to reach out to us.


Thanks,
EPS Team

The EPS Post above was discredited on another Forum. EPS were unable to rebut the challenges which may call into question any/all claims they make.
