+ 3rd option is the one you have chosen for the 4 years the IMSB retrofit has been available. :dance:

I am with you though Johnny on not wanting to ship your car. In fact I have never had any of my cars in the shop except for tire changes (even then I only bring in the wheels) and paint (but not body work). I prefer to do everything else myself. So the IMS Solution is also not really an option that I would personally consider at this point in time. Kinda irks me a little the way they are marketing it, but in all fairness it's not my business how they run their business and if they chose to do it that way they have to anticipate that they will lose potential customers like you and me. Sooner or later here I'm just going to have to bite the bullet and do the Retrofit on my 986 and 996, even though I will be keeping these cars until either I'm dust or they are rust.

Jake, I have a 2000 Base with a manufacture date in late August of 1999. As I understand it, the 'IMS' solution is not available for the earlier twin row bearings; however, there is no way to tell whether my bearing is the older twin row, or the later single row without disassembly. If I order the IMS update assuming it to be twin row and my mechanic discovers on disassembly that is single row, I will need to have my car reassembled then shipped from Ontario, Canada to your shop for installation of the IMS Solution, then shipped back to Canada. Or am I missing something? In those circumstances, would the IMS update still be available if it turns out that I have the single row bearing?

Aren't you supposed to take the trans off and look at the narrow/wide IMS flange seen in pictures here What IMS do I have? | IMS Retrofit to see if you have a single row or double row before ordering as the kits aren't returnable.

And assuming you aren't the original owner and thus could have a replacement engine you didn't know about, how long you've had the car could prevent you from having the third generation IMS or thrust you into the possibility of having one. You ID the 3rd generation by the 22mm nut.

LN's site still lists both style bearings (single and dual row), and I have not heard of any plans to discontinue the single row style.

Another IMSB related question. I was going to have a "Preferred Installer" in Pasadena CA put an LN ceramic IMSB in my 2003 Boxster S that I recently bought, for peace of mind. Then, low and behold, today I discovered the service booklet with the owner's manual, which says the engine was replaced in October of 2006 (not IMSB related). My question is, what should I do? I know that after 2005, the engine cases need to be split to install the IMSB. Is my only reasonable recourse to get the engine number and see which bearing it needs? I don't want the installer to pull the transmission and clutch, only to find out that I don't have the single row bearing. I don't need a clutch, it was just recently replaced, and the dealer said the IMSB looked fine, whatever that means. Suggestions?

If the engine was replaced in October of 2006, it has the non-serviceable oversized IMS bearing that would require a full engine tear down to replace. But you still have some options: Add a Guardian warning system, which would alert you should the bearing (or other major component) start to go south. Switch to a high ZDDP full synthetic oil, add the LN spin on filter and magnetic drain plug. If at any time in the future the trans has to come out, like a clutch job, have the rear seal removed from the OEM IMS bearing so it gets splash lubrication. Any, or all, of these would help in the long term.

JFP in PA, the installer says he thinks they would have put a 2003 engine in a 2003 Boxster, even in 2006. I wonder if maybe he just wants to work on the engine. Sounds like I need to get the engine number and try to see if Porsche can tell me if it is a 2006 engine, or an older one that would have the single row bearing. Can you tell me where the engine number is?

The installer doesn't know Porsches like he says he does.

See Jake's post of yesterday where he says the only way the car got a second-gen IMS engine was if someone somewhere someone had squirreled away a engine for several years as all the engines even for several years prior to when yours was done were third generation IMS setups.

And they didn't tend to sit around as they were used as replacements pretty quickly. No one wants an inventory of $10k+ engines sitting around. And I recall that even the US Porsche distributor usually had about 10 several years ago so they were moving them out at a pretty good clip.

Jake knows, he is inside these engines more than anyone around. He has seen all the surprises.

On the rail along side the sump plate on the bottom of the engine:

The "AT" indicates it is a factory replacement engine (reman). All reman or crate engines shipped or installed after 2005 are the large IMS bearing, the numbers say yours dates later than that; the IMS cannot be replaced.

Yay; an answer! I guess I'll just change the oil often, check the oil filter, and drive the heck out of it!

As a person who just chose to have this procedure done, I could not be more pleased. I dropped my Boxster off at Flat 6 on the way down to Destin FL for a vacation, knowing that they would not be able to get to it right away, as they are quite busy. Dean gave me an amazing tour of their facility and I was quite impressed. My car arrived back on Sunday, so I have had three days of driving it and my impression is that the car runs much smoother, Less vibration from the motor, and for some reason, drastically minimized the 3,200 rpm vibration.

Jake and Dean took great care of the car while it was in their possession, and that comes from a person who is very picky and crazy protective about his vehicles. My warranty from Porsche expired at the beginning of this year, so I always had the slight fear in the back of my mind of a part I have no control over. Now I have better feeling of peace and know that I can hand it down to my daughter when she becomes of a proper age (as one of her first words was Porsche) and keep it in the family.

I already had one of Jakes early M96 motors with all L&N parts, nickies etc and I went with the new IMS replacement. If I hadn't already bought all the parts I would upgrade to the largest displacement I could get and buy a different crank but I just can't justify making it faster anymore. More reliable, always! In addition to the aforementioned reliability benefits my car came out of it with ~10-15 more HP. Jake didn't expect it, nor does he make such claims, but it happened with my car. I'm less than an hour away so my car is there for regular oil changes and Jakes staff knows it very well. The last time I was there, 5k miles after the upgrade, I was asked how it was doing and could only honestly say that the upgrade was seamless to me. If I didn't know I had an additional oil line, I would have no idea I had a gorgeous new hunk of metal that slides back and forth with such ease.

To be fair my engine was not built to maximize HP, but seat of the pant torque, so a little may have been unlocked that wasn't searched for originally, who knows, but it was the same dyno it's always been on. I don't really feel the additional HP, I think because the torque is such that I rarely if ever get anywhere near max HP as the torque across the band is more than enough to keep a smile on my face wherever I go. I make it a point to cross the mountains around Cleveland every chance I get. I haven't been on I-75 to Knoxville in the 40k miles I've had a Raby motor and I go there regularly to see family. In 40k miles I've never had one problem of any kind with my Boxster. The car has now been Raby powered for half its life.

How much is it to do a ims solution on a 2005 987s, installed?

For just the parts alone, the IMS Solution adds around an additional $1K over a ceramic hybrid installation, and about 1 to 1 1/2 hours of additional labor to machine a notch in the engine cases to accept the oil line, mounting the special spin on oil filter adaptor, sealing the IMS shaft, and routing the braided stainless line that carries the oil to the IMS flange.

That said, before we do any retrofits on a 2005 car, it has to come apart to make sure it has a serviceable IMS bearing rather than the oversized bearing. With a 2005 car, there is no way to know which bearing is in the engine without opening it up and looking.
