Yes, I know. But if you look at the basics of the engine, hey, this is not rocket science.

If you have to make the block heavier to accomodate a tougher alloy, DO IT.

If you have to beef up the shafts and/or pistons, rods etc. DO IT.

We should not have to put up with this bad boy grenading whenever!

I think it's fairly simple to explain. They put their crap in the cheap cars to save money, knowing they'll sell based on their name.

Unfortunately so true.

On the other hand, it is semi surprising that no one in the states is rebuilding these motors yet. There are plenty of shops with the equipment necessary to do what Autofarm is doing.

The one question I do ask about the "Silsleeve" conversion, is cooling. By running a much thicker sleeve, they are effectively reducing cylinder cooling. I do love their solution for the IMS problem, however.

My IMS failed two weeks ago on a 70k 2003 Boxster S. No audible warning - was running like a Swiss watch then bang and the horrible sound of ball bearings bouncing around your engines internals. The car has a full and extensive service history and was 6k away from its next service.
I look forward to the rebuilt motor giving me some peace of mind.

I'm a new owner of a 99 base 986, 39k miles with tiptronic. It was a garage queen that wasn't very well maintained (or driven enough). She developed a RMS leak after my first track day, so I decided to bite the bullet and do the LN IMS upgrade. After removing the seal from the old bearing and draining out the oil, it looks like I dodged a bullet.

Yep, stage 3 failure right there, folks! Had you not ripped the seal off and washed the debris and oil out that bearing would have "felt" fine.

You dodged a bullet for sure.. The only reason that the bearing is still together is because its a dual row... A single would have already completed stage 4 failure and you'd be done..

You got lucky. Mine looked just like that when it got swapped out.
Now go and drive the %!$$ out of it.
