It's 2013 - any updates on IMS issues or cost of engines?
So it's now 2013, and a good amount of time has passed since the IMS issues were found. To be honest, as a new Boxster owner, there is a tremendous amount of information and fear through various forums of this IMS failure - which does happen, albeit it seems to be rare. (But not rare enough)
Having said that, I have a 2001 Boxster - no issues so far, 54k miles. The previous first owner drove it about 40k miles in 5 years, and the 2nd owner only 13k miles in 6 years. Now I have it, and obviously am driving it for fun much more, so the IMS issue worries me. Basically, $2k is not expensive with the clutch and IMS upgrade - but in 2013, just how much is a replaceable good condition engine in case the worst happens? I've seen some working engines on eBay in the $3k to $5k range for a 986 2.7 liter like is already in my 2001. Is that a good range for the real world, or are these eBay auctions not reliable and trustworthy for a good engine? Heck, if a new (used) engine was only $3,500 plus a few hours of installation, that does not seem like the end of the world, and only a little bit more compared to a $2k IMS upgrade job. So the question remains...with lower engine prices, risk it or still do the IMS... I do plan to get a 2009 Boxster most likely next year, so I need the car to hold out for at least another 1-2 years and 15-20k miles! |
I got an email back in December from Flat 6 (Jake Raby's Company) that said they developed a new, permanent fix for the IMS bearing. They apparently eliminate the roller bearing and replace it with a conventional, oil fed bearing. I didn't see any info on pricing or on whether the replacement can be made without engine disassembly. They call it the Ultimate Solution, I think.

another advantage of doing the IMS, and sooner than later, you'll stand a better chance of being able to re-use the flywheel. That added like $700 to the cost of my clutch/IMS/RMS swap bringing it close to $3K. Pricey.
As for putting it off because used m96 engines may be getting cheaper. I wonder about that. Older Boxsters and Carreras are coming down in price to the point where many will be using them for daily driving after the cars spent nearly the first decade of their existing as garage queens. I tend to think that will shake out the bad apples at an accelerated rate. Which in turn could increase the demand for engines. However, this might be mitigated by the number of cars that are totaled (frontal impacts where the engine is immediately sold) as a consequence of more Boxster/Carrera miles being driven. Either way you are replacing a question with another question when you replace a grenaded engine. And you are doing so at a premium over simply swapping the IMS. I don't have a reason to believe that a well maintained m96 engine will not last well past your needs. |
great thread on pelican about an oil-fed ims:
Who has done an IMS change (New Oil Fed Design Idea) - Pelican Parts Technical BBS started about a year ago. now Raby has one in development. parallel evolution? from what i can see, feelyx taps the block and runs a line internal to the bellhousing. the raby solution uses an external oil line (from a sandwich plate on the filter?) that passes through the bellhousing. both use an exposed bearing and a modified cover plate with an oil fitting. one of the things that feelyx's design does that i'm uncertain the raby one does is move the bearing further inboard in an effort to reduce radial torque on the bearing (presumably one of the causes of failure, along with insufficient/failed lubrication). |
You guys are right, ims upgrade makes sense.
I'm going to wait a couple of months, then I will have an idea of how long I'll keep the car before I get a newer one. If its longer, I'll do the ims upgrade. |

All of our engines are now utilizing the IMS Solution. Active sales through shops and major distributors will begin in summer 2013. Until then the only place to get it is where it was invented, right here :-) All sales will be through shops by IMS Solution LLC. This development is not intended to be sold for DIY installations. Units will not be sold at a retail level. Anyway, engine prices aren't dropping- they are going up just like everything else these days. Last year after many years the OEM crate engine price from Porsche finally met the price of my engines for the first time. This year our prices increased for the first time since 2007. Interestingly the price of my engines 5 years ago was over 15K for any ofering while the factory Porsche engine price was only 5-7K. Today the price for our engines is generally 18-20K and any engine from the dealer is also the same price, but the factory core charge is equal to or more than the cost of the engine and you may not see any of that money back. Because the OEM prices have risen and our engines become more and more respected we are busier today than ever. I currently have cars in-process for engine reconstructions from 20 states and 2 Canadian provinces due to this. The parts and processes to create one of my engines cost over14K for any engine and some are as much as 16.5K, but we have more and more people wanting to go my way, in fact I have sold three engines so far this year and didn't even try. There are more corner cutters popping out of the wood work to "rebuild" these engines and they offer cheap prices. You will get exactly what you pay for. Results may vary. |
What? The current LNE IMS bearing retrofit is not good enough?
|
Quote:
Basically all we have done is backdated the bearing design to that of the aircooled engine that utilized a layshaft. GT3/ Turbo engines also use the same design. |
Quote:
The entire concept is fascinating. Am I to understand that this solution, if oil starvation is a/the prime failed IMS culprit, basically works/addresses any m96 bearing? If that is indeed the case it really makes you wonder why the guys in Germany didn't do this from the start or at least afterwards when they were debating moving from single row vs. dual. |
Quote:
The only reason thats logical as to why the factory did not follow the previous designs of the Metzger aircooled engine or any other engine that uses a "layshaft" is because of cost. The M96 engine has a crankcase that is cast with 1/3 the amount of internal oil passages that were found in the aircooled engines. Because of this there are no pressurized oil passages in the region of the IMS and adding them would have been extremely expensive, requiring major redesign of the crankcase. All of this increases production costs and we already know that the accountants were in charge of engineering. The use of a "permanently lubricated" bearing allowed the engine to be built with less internal passages within the crankcase, meaning a crankcase that was simpler to cast and machine. This means it was cheaper to build. All previous Porsche engines that utilize a plain bearing with a pressure fed design have historically never experienced any sort of "IMS Failure". All we did was make a retrofit thats possible with the engine installed into the car and assembled and used the same type design as the engines that date back to 1955. Here is a picture of a 547 4 cam Carrera engine from the 1950s that utilizes a layshaft to carry out the same job as the "IMS" in your M96 engine. Note the method of bearing support that is utilized. The IMS Solution design goes one step further and also sets the "end play" of the entire shaft with one easy to install, pre-set arrangement that bolts right in. http://www.rdtlabs.com/Pictures/4cam...ics%20307.html This retrofit only takes one hour longer to complete than a standard IMSB retrofit using the current LN bearing. That extra hour is just to install the oil filter adaptor and the external oil feed hose. We'll open the IMS Solution web page next week and have some videos posted of how it works to help you better understand it. |

And here is how you can make your 20K one like the 50K one :-) Pictures have NEVER been posted anywhere before this.. Not even on our sites. You'll find no info about this anywhere online today, not even our sites or LN. :-) |
Pretty impressive Jake.................
|
I don't believe Jake is making any claims as to an increase in power with this upgrade, but my car saw a significant increase in HP with this solution. Granted I have one of Jake's balanced HP 3.6 motors, but I had to have the final solution. The pictures of the parts above simply can't do the real thing any justice. Sliding the parts together in your hands and realizing there is no bearing to disintegrate and dribble particles into the motor is something I just couldn't resist. My first question to Jake was why didn't Porsche do this? The answer of course is $$$$$ like everything else, and in 96/97 Boxsters weren't cheap cars and the 2000 996 I had carried a sticker of over $80k. I didn't buy it new, but the guy still had the sticker. Porsche was broke though at the time, and the M96 project catapulted them back into profitability and left us with motors that were not engineered to previous Porsche standards. In spite of that I still want to drive a Porsche. The Boxster I drive to work everyday looks like any other 986S, but I can run with just about anything on any kind of surface and I know I can drive it every day for as long as I want to. This is my 3rd M96 car. MY only regret is that I didn't find out about about Jake when I still had my 97. It was silver with the red full leather and I could have made it look like the one in the Porsche museum for not a of of extra money. Not that I'm not happy with the rainforest green, it's not an everyday color, which is why I bought it, but the classic silver lightweight 97 would have been my first choice or maybe the 2004 GT silver special edition. I would recommend to anybody who likes his Boxster and wants to keep it, to seriously consider one of Jake's upgraded engines. It is worth every cent and then some. AS info, I have no affiliation other than I am a satisfied customer of flat6 that happens to be lucky enough to live about an hour from Jake's shop. I heard about the IMS development work on one of the forums, either here, or more likely Rennlist and jumped right in.

I LIKE!
Jake, I'm sure some of us on this forum could install this solution with your directions. Not that I'm in any hurry to replace my single row LNE bearing at this time, but some of us like doing this kind of work. Your thoughts? |
Quote:
Raby, I take my hat off to you - that thing looks like it comes strait out of NASA. I'll bet you spent a lot of time and effort to get it this far, & going on your past efforts over the last few years, I'm sure it will work exceptionally well. I hope you make a million $$. But beware, to doomsday protagonist's won't be far behind, predicting all sorts of hate & fraud & deceit. You'd better prepare yourself - but you've been there before & know what to expect, so just ignore them. Thanks for your dedication..... Steve |
Jake, don't know if you will see this but will I be able to go to my Porsche dealer this summer and have this installed in my 2002 S? I was thinking of doing the LN bearing this summer as my 2002 has only 14,000 miles on it so I feel like I am driving a ticking time bomb as most failures seem to happen in early miles. Thanks for all you do. These are such fun cars to drive and your solution would only add ten fold to the enjoyment.
|
I'll try to respond to everyone in the past few posts with just this one post. Steve first.
Quote:
By design the IMS Solution should make more power because it is hydrodynamic and no materials contact each other as everything rides of a thin film of oil, unlike the factory ball bearing. Even though Steve's car did make A LOT more HP that could be felt in the driver's seat and certainly on the dyno we still won't claim any HP gain for the development. I'll post his dyno before and after on Monday. Quote:
But Charles and I are done with that sort of thing with these critical components. I suppose a DIY'r could buy the IMSS from their local shop who can source it from their wholesale supplier who will be distributing these. This way the shop would have to offer the support and the DIY'rcan still do their own work, keeping us out of the loop. With this technology we are requiring the installers be instructed on how it works and things like webinars will be utilized to ensure the shops know the differences in the technology and what needs to be done to optimize the install. I have also added the install of the IMSS to my M96 Complete Engine Mechanical Class that I instruct for the Worldpac Training Institute. This will train 350-400 installers across North America about the install in 2013 alone. That will help a lot. I have included a chapter in my M96 Engine Bible that goes over the install as well and includes a ton of info about how it works, this wil also share the info right from the source and will do so VERY SOON :-) Charles and I want things to work and we don't want issues, we also don't want the phone to blow up with people making dumb mistakes, because those people get pissy when things don't go perfectly. I have moved completely away from selling retail for anything other than my engines, heck we don't even sell the IMS Guardian direct anymore, I gave all the sales to LN. Quote:

FYI- The VERY FIRST time that Charles and I disassembled an M96 engine I saw the IMS bearing (that at that time did not have such a widespread bad reputation) and I said "Why the hell did the idiots use that sealed bearing? That needs to be a plain bearing." so then we designed a plain bearing and made it work. It was that simple. It has taken YEARS to get it to market, heck I even wanted to perfect it and bring it to market BEFORE the ceramic ball bearing (current) IMS Bearing. Charles didn't want to do this since the ceramic bearing was already developed and tested, so we brought the ceramic bearing to market first. We had bad luck with the first three generations of the IMS Solution during testing, so we decided to go ahead and create the ceramic bearing kit and take more time to perfect "The Solution". Quote:

A funny story occurred recently when the owner of an IMS Solution powered car took his 996 to a dealership to have a race alignment and the technicians saw the oil line going into the bell housing and they had no idea what it did. Pictures of that went viral throughout Porsche dealerships across the country and they even ended up coming back to us from Europe. The owner acted dumb and said he had no idea, that he just bought the car and didn't know that anything special was done to it. None of those people have ever figured out what the oil line was there for, to my knowledge. (LOVE IT!) Quote:

Jake and others:
It's fantastic to have such support for the engine on these cars. But it does lead me, as being new to Porsche, to be fairly disappointed that such a large issue exists. All cars have wear and tear, but for a car to eat its own engine (and often at low mileage) is extremely unacceptable. From my understanding, cost cutting at Porsche during rougher years is what lead to this unreliable fact. By the way, I have a BMW and am active in that community and love cars; and I had never heard of this Porsche IMS issue until I started to more deeply research it. It's everywhere to be read, but for non-Porsche owners, you'd never know it. Disappointing. |
Quote:
Porsche has made mistakes with just about every major change in their development process. I think the jump to M96 is worse than most, but a top end rebuild for a 993, to turn out the check engine light to buy your tags can run you 12 to 14k. BMW has had their share of engineering problems as well. The first E46 M3 engines were replaced by the boatload, but almost all of them tanked while under warranty. The "automatic" transmissions in those same M3s continue to fail at a high rate, and a dead battery can cost you several hundred dollars, a tow, and a software upload from the factory for every major system. I only bring that up to highlight that all manufacturers have their issues. The real difference here as I see it is that Porsche refused to do anything about it but do an engine swap, and refused to provide any internal engine parts, tools, or even rudimentary failure rate data. Porsches' actions and non actions resulted in depreciation that has made the cost of entry into the used Porsche market to be possible to anyone. Jake and Charles have made it possible to be able to maintain those "inexpensive Porsches" if there is such a thing, to a high standard. We owe them more gratitude than I can describe and I hope Jake and Charles make more money than they can ever spend on these projects. Who knows what they'll come up with next? |
That's true about every manufacturer having issues, but Porsche seems too quiet on this subject. At least BMW had recalls for the HPFP issues and extended the warranties greatly.
|
My opinion is that the failure rate is lower than some of the other Mfg. issues mentioned, so they were able to mostly ignore it.
|
I disagree. They didn't ignore it. They setup an unprecedented process for re-manufacturing engines and were turning them around and doing engine replacements in every dealership in the world, save some of the smaller ones. Anyone that bought their car new usually got a new engine past the warranty period, especially if you were a repeat customer, or at the very least free labor. They wouldn't do anything for those of us who bought the cars used. That's not unusual for manufacturers but it sure contributed to the depreciation levels of the cars. The headlights didn't help either with the purist crowd, nor did the plasticcy interior, but every enthusiast considering buying a used Boxster or 996 became aware of the issues. In any event it's now possible to buy a really good modern used Porsche that can be daily driven for quite a bit less than a 30+ year old 911 that's not really a good DD for most people. I love those old 911s and still have an 80 model, but I wouldn't drive it back and forth to work 70 miles round trip every day, especially in the summer. Spending an extra few thousand to make the engine reliable is a pretty small price to pay IMO. Going further and making power the chassis is designed for is just gravy.

We started working with the M96 before anyone else to gain a serious lead on the competition, and it worked very well. Today it'll take 5+ years for anyone to catch up if we stopped in our tracks. As we move forward we already have two years of development and engine building into the 9a1 engines and have already found deficiencies and eliminated them. Its constant evolution and thats what drives Charles and I. I am really bad about only wanting to develop, by the time something is ready to be sold I am so done with it and have moved on, that I don't even care if it sells. All new cars are built like anything else today... To be "just good enough". This opens doors for innovators like Charles and I. Back when I first started my company all Porsches that had the engines where the belonged didn't have radiators. With those cars it was very difficult, and usually impossible to beat the factory at their own game. With the M96 its been much, much easier since so many compromises existed. Today the only Porsche engine that impresses me is the Cayenne, other than cylinder issues (stupid damn lokisil in the non TT versions) the Cayenne engine is built like a tank with serious heavy duty parts that do not break. I am currently designing a big bore, 5.3L Cayenne based engine that should hold together with over 1,000HP of output. Quote:

Jake,
You haven’t given-up on making DVD’s “How to rebuild M96/M97 Motors” have you? I have been patiently waiting. |
Quote:
The issue with a DVD is keeping it up to date. I have no plans for a DVD now and scrapped most all the footage I already had. Updating my book yearly as we learn more is easy, not so much with a video series. The classes have taken over; I travel the USA and Canada for the Worldpac training Institute and have a class somewhere every 4-5 weeks. We offer our engine rebuild school here at Flat 6 once per year for 4 days, but it disrupts our R&D and production so much that I may have to move that class elsewhere because time is the commodity that we do not have an excess supply of. The WTI class is a "complete M96 mechanical class" where we cover IMSR, and etc as an entire two day overview thats not hands on. My engine rebuild school is 4 days in my world and is all hands on. |
Putting things in perspective...at least a I see it.
The IMSB issue gets a lot of air play because the consequences of it falling are catastrophic - $10K to $20K to replace the engine. That said, all mechanical systems can fail - Porsche's original design as well as all aftermarket replacements. So the real question is: how do I manage my risks. For me it comes down to a trade-off of cost of replacement versus probability of failure. Anecdotally, I've heard that the original Porsche IMSB's failed at about a 5% rate. The Pelican option is an incremental improvement over the Porsche design. Most likely, it fails at a lower rate although I haven't found an estimate published anywhere. About a half dozen single row LN bearings have failed out of perhaps thousands of installations. I get the sense that the LN IMS Retrofit bearings are at least 10 times more reliable than the original Porsche designs. It must be noted, however, that the IMS Retrofit bearings developers recommend their bearings be inspected with every clutch replacement or at 60K miles of use. The forthcoming IMS Solution claims to have a near zero, if not zero, probably of failure and requires no post installation inspections for the life of the engine. The costs of replacement from $0 (doing nothing) to about $3K to 4K at the top end depending on replacement bearing chosen and what shop does the work. I've weighed my options and tolerance for risk and I know what I plan to do. Because the risk-cost trade-off is so personal, I'll leave to others to decide what they want to do. |
The IMS Solution removes 13 wear components from a single row IMSB equipped engine. These are replaced with a bearing flange/ support and a bushing. Clean, pressurized oil becomes the new "support surface".
This is not new to the M96 engine; in fact the other end (oil pump end) of the IMS is supported with this EXACT same technology with pressurized oil from the oil pump directly feeding it. This pressure and volume is exacting what we deliver to the IMS Solution through the spin on oil filter adaptor. The "other end" of the IMS never wears in these engines, not even if the engine suffers from oil starvation on the track. As always Less = More. |
The real difference here as I see it is that Porsche refused to do anything about it but do an engine swap, and refused to provide any internal engine parts, tools, or even rudimentary failure rate data. Porsches' actions and non actions resulted in depreciation that has made the cost of entry into the used Porsche market to be possible to anyone. [/QUOTE]
I hear many say that our car problems is the reason why they have depreciated so much. Some of that is obviously true but have you priced ANY german car that is 6-10 years old? Take a look at the M3 from around 2003. There is one near me selling for 15K and that wasn't the cheapest one. 04 MB SL 500s are going for 20K. I like my car but I don't think they depreciated enough to reflect this problem if its really that bad. I appreciate the solutions from the aftermarkets. Hats off to you guys.:cheers: |

^ I lived just outside of Atlanta briefly in the late 90's. Absolutely the worst traffic I have ever experienced in any major city. It wasn't so much that the traffic tied you up for so long but that it was virtually guaranteed every day with no apparent remedy.
Folks were getting up at 4am to get to work at 8am. They don't even do that in NYC on a bad day. |
I totaled my 2003 M3 a few months ago. Granted it had only 43k miles but my insurance co gave me 23900 for it. That was NAdA retail + 4500 for the low mileage. I couldn't replace it for that though not one with that mileage and pristine condition. The closest I came was a 2002 with 18 k miles. I was about to buy it at 27 and the guy backed out. He was one of mu vendors and toldd he felt pressured to sell it to me so I just walked away

The difference is that most Porshe (i.e, early 911) owners are used to their cars holding significant value and not dropping like the rest of the used car market. The reality is that Boxsters and other water cooled Porsche's are now just like any other car (from a re-sale point of view). |

That said, for a daily driven car with modern amenities you cannot beat the Boxster/997/997 Cayman all around. To me a Porsche isn't supposed to have good heat, good A/C or amenities, I like the raw feel of an early Porsche and drive that everyday. Love this car... I just have to finish my 356 before spring so I can fall in love all over again :-) https://sphotos-b.xx.fbcdn.net/hphot...64505220_n.jpg |

p.s. I don't think a comparably priced Boxster was down to $11K after only eight years. Well, not if year eight came before the stock market crash/credit crisis of 2009. I was checking prices pretty regularly back in 2007-2008 as I was about to add a red/tan 996 C4S and just park the Boxster during winter. Glad I backed off. 996 prices took a severe beating begining in 2009. Some dropped $30+K in a single year. I knew of one guy who picked up a 996 Turbo for less than $30K cash. And if we ever fall into a similar credit crunch (feasible) I'd hate to see what would happen to those lofty 991 prices. |

Hi Jake,
When would you estimate the availability of the IMSS service/replacement by shops outside of your own would be ? Specifically in the Toronto area. |
