Thought I would post my results for what its worth to others who are thinking of doing this, and to Rajaie for putting this product out there.

Instructions were perfect. It took me about 8 Hours over three days, taking my time, cleaning each part that came out, etc. I was waiting for the parts anyway from Beisan and Pelican (quick delivery from both outfits), and I am glad I took my time. I had a chance to take proper inventory of all the tools I would need, and running the disassembly/assembly procedures in my head before starting. Most likely unnecessary, but I like it that way. I find extreme pleasure when something is executed to PERFECTION. Print Raj's guide - you'll find the guide very useful during the install, and to make sure you don't miss anything. And if you're anywhere close to my level of Anal Retentiveness, you cannot attempt this without a torque wrench (I used two to accomodate the different ranges).

As for the actual results, the car started right up. I drove it the night I got done with the install. I didn't notice much of a difference, and whatever I felt could have easily just been in my head. Then again I took it on the freeway, where none of the expected results would be felt. I was also quite tired, and was probably just looking forward to the burger I was about to have. Yumm. Then came day two -

I drove this thing around town this morning. Lots of traffic lights, braking and acceleration. Now I see what everyone was talking about. The car is much more torquey below 3k, and hardly has to downshift to get going. For me the real benefit to the repair is that now the power is "always there", car goes without having to get to another gear, and is certainly much smoother. That BMW "grunt" is there again, which ironically I never thought was lost.

At 48k miles of mostly freeway miles in CA, I didn't think I would benefit from the seals change. I did it anyway because 1.) the "what if" and 2.) hey, it's a DIY! I have fun taking things apart and seeing how they work. I'm glad I did it. I can't stress how much more pleasant the engine is to have it go through the gears. I also have 2.5L, and every bit of torque is appreciated.

To the ones planning this, my only thoughts are to have the tools before hand, and to take your time. Don't start this if this is your only car and you have to pick up the wife in a few hours. It's not that kind of job, at least to me it wasn't.

Everyone's wrenching skills will be different. I'd say confidence is also required. If you have doubts about your DIY skills, I'd probably stay away and have a competent guy do it. If you're reasonably sure about yourself, Raj's guide is all you need to get started. And regardless of who ends up doing the seals swap, you'll surely be glad you did.

I can't wait until the seals are fully broken in. I've gone on a couple short trips so far, and it gets better with every stop light. Come to think of it, I've come to welcome stop lights, if only to feel that smooth BMW power delivery, going through the gears, and putting a smile on my face.

Best Regards,
Paolo
