Most guys on here are in a state of anxiety over the IMS issue...which again I think is overstated. But, hey, lets look at another option. Instead of paying $4-5k for this upgrade replacement bearing. Go on ebay and by a replacement engine. I can get one a 3.2 for my car with very good mileage (50k) for about $2k. Now I prep this engine and make sure its sound. Maybe putting in a new bearing, seals, etc. and having it ready to go. Lets say I never have to use it and I sell my Boxster and get something else. Now that engine setting in my garage can now be redeemed for cash...like having a savings account. It was there when I needed but never used it. Get it.
