M96 M97 1997-2008 Boxster Cayman 911
Nickies Engine Block Sleeving Solutions for Boxster, Cayman, and 911 models with M96/M97 Engines
When planning to rebuild the flat six Porsche M96
engine or M97 engine in your Boxster, Cayman, or 911 vehicle, there are many considerations when evaluating your options
to correct for bore scoring, intermix, cylinder cracking, d-chunk , and even
slipped sleeve failures. Replacing a failed engine with a good used engine,
factory shortblock, or new replacement engine, you are using an engine with the
same Lokasil cylinders that can and will fail. Some builders will rebuild an
engine and not address cylinder issues, while others will use inferior steel
sleeves, often resulting in repeated failures. Nickies aluminum nsc-plated
cylinders are the only sleeves proven to address these issues found in the
problematic M96 and M97 engine using the same cylinder technology used in
Porsche 911 Turbo, GT2, and GT3 models.
Why use LN Engineering for M96/M97 engine sleeving?
With thousands of engines fitted with Nickies over the span of
more than a decade, no one has more experience than LN Engineering when it comes to solving cylinder issues associated with Lokasil
engine blocks, especially with displacement increases up to 4.0. No one has been
sleeving big-bore M96 and M97 engines longer than LN Engineering anywhere in the
world.
How much does it cost to rebuild a Boxster, Cayman, or 911 engine (986/996 and 987/997 models)?
Although you may find "budget" Porsche engine rebuilds advertised for under $20,000, it's a guarantee that the cylinders have not been properly reconditioned and that what they are quoting is likely no more than fresh gaskets, bearings, seals, rings, and a valve job. However, with an M96 or M97 engine, there is much more to a proper rebuild. Be sure to ask for a parts list of what is reused versus replaced (read the fine print) and you'll quickly see the difference between a "budget" rebuild and one that has been properly rebuilt including our Nickies sleeves and featuring our IMS Solution and other required upgrades to make these engines bulletproof. If the shop doesn't use Nickies in their rebuilds, keep looking for another builder.
The cost really isn't much different than rebuilding an aircooled 911 engine. As a rule of thumb, a basic M96/M97 rebuild with Nickies is going to run you about $20k, more for engines with ported heads and other internal upgrades like forged connecting rods. There are lots of ancillary components that should or need to be replaced like fuel injectors, MAF and o2 sensors, dual mass flywheel, clutch, expansion tank, and other items, especially on a car that is 15-20 years old. Cutting corners anywhere in the process can end up costing you more in the long run. Many don't have enough money to do the job right the first time, but have more than enough to do it over again.
And yes, it is possible to spend as much on an
engine as what the car might be worth. The question you have to ask yourself is
what is it going to cost you if you go out and buy a new Porsche. Will you get
as much enjoyment out of a new Porsche than building up your current engine and
keeping your car? Just ask those early adopters over a decade ago that had us
punch their 3.2 Boxster S and 3.4 996 engines to 3.8 liters and 3.6 996 engines
to 4.0 liters and owners of the thousands of aircooled and watercooled Porsche
vehicles who have trusted our Nickies cylinders and sleeves.
Why can't you just re-ring the pistons and re-use the block as-is?
You get what you pay for. Re-ringing your isn't an option for most rebuilds, however most engine builders re-ring engines after only doing a visual inspection of cylinder bores for obvious cracks or scoring without measuring the cylinders for ovality, taper, and proper surface finish. Most shops don't own a profilometer to verify Ra, RpK, RvK, or Rk, let alone precision measurement devices, to be able to inspect the engine block. In fact, most every used engine we have ever inspected has more than the allowable 0.08mm (.0032") ovality and taper specified by Porsche. Having had the change to inspect numerous new engine blocks, we know they are near perfectly round with less than 0.02mm (.0008") ovality or taper.
It is a guarantee if the engine has not been reconditioned either by sleeving or direct plating, the bores are out of spec on even a "fresh" rebuild. If the bores do happen to be in spec, there is also the issue of other known modes of failure associated with Lokasil and Alusil engine blocks including, but not limited to d-chunk, cracking, and scoring failures. Nickies cylinders with NSC (nickel silicon carbide) plating, similar to Nikasil, address all known cylinder weaknesses that direct plating of blocks cannot address.
What is bore scoring and how do scored 996 and 997 cylinders affect M96 and M97 Porsche engines?
The Boxster, Cayman, and 911 from 1997 through 2008 use the Lokasil hypereutectic engine block casting technology, which is similar to Alusil, both developed by Kolbenschmidt. Alusil is has been used in many Porsche models including the Porsche 944, 928, and 968. This also includes the Cayenne V8, Panamera V6 and V8, and most recently, 2009 and later models with the 9A1 (MA1) engine found in Boxster, Cayman, and 911 vehicles.
The silicon particles in the Alusil and Lokasil cylinder bores are exposed through a mechanical or chemical process that removes the surrounding aluminum. The piston/ring/cylinder system is supported by these exposed silicon particles and the oil film on the bores. If there isn't sufficient exposed silicon particles or oil film, the cylinder system can no longer function normally.
To prevent aluminum to aluminum contact of the pistons and the cylinder bores, the pistons are iron clad. When the iron coating fails, adhesive wear (scoring) of the cylinder bores can occur. Cylinder bore scoring isn't limited to just Lokasil engines - it can occur with Alusil or any other hypereutectic cylinder technologies.
Symptoms of bore scoring on affected models includes piston slap
and excessive oil consumption. Engines with scored bores are often misdiagnosed
as having noisy lifters. Another indicator besides piston slap is having one tail pipe
sootier than
the other, with the driver's side tail pipe on a 996 or 997 with scored cylinder
bores getting sooty first. Boxster S and Cayman S models with the 3.4 engine
will have the passenger side tail pipe get sooty first. Even before there is any noticeable oil consumption,
piston slap caused by the increased piston to cylinder
clearance and sooty tail pipes can occur. When oil consumption becomes excessive,
spark plugs can become oil fouled causing misfires on cylinders 4,5, and 6.
Vehicles with excessive oil consumption will likely also have significant oil
film on the rear bumper cover.
How can I prevent bore scoring?
Besides the failure of the iron clad coating on the piston skirts and fracturing of silicon particles on the cylinder bores, both of which will result in bore scoring, we have determined that bad fuel injectors as well as vacuum leaks can lead to cylinder bores being washed down from un-atomized or excess fuel. Fuel is not a lubricant, especially ethanol enriched fuels that have reduced lubricity compared to ethanol-free unleaded fuels. Dirty injectors can result in poor fuel atomization - un-atomized fuel does not burn and will up washing cylinder bores down and lead to high fuel dilution of your engine oil. Leaking injectors will bleed down, dumping raw fuel into the bores, washing away all lubricant at start up, increasing cylinder wear. Likewise, vacuum leaks will make an engine run rich, again washing the cylinder bores down. Smoke testing your engine for vacuum leaks and monitoring fuel trim values are two easy steps you can take to make sure you lessen the chance of bore scoring in your Porsche engine.

Scoring in AlSi Cylinder Systems.
How common is bore scoring?
When we started sleeving M96 engine blocks with Nickies in 2008, most of the
cylinder failures we experienced were not bore scoring related, but rather
cracked cylinders, d-chunk, and slipped sleeve. But as these cars have gotten
older, bore scoring is the number one failure we see, specifically 996 and 997
models. Bore scoring is most common in Porsche 911 vehicles, including 996 and
997 models, fitted with the 3.6 and 3.8 engine. The 3.4 engine fitted to Porsche
Cayman S and Boxster S vehicles is also susceptible to bore scoring. The 2.5,
2.7, and 3.2 Boxster and Boxster S engines as well as the 2.7 engine fitted to
base Boxster and Cayman are not known to suffer from scored cylinder bores.
How can I determine if I have scored bores?
Besides the obvious symptoms of piston slap and oil consumption, borescoping
the cylinder bores and performing used oil analysis can help identify early
cases of bore scoring before there are any symptoms. When bore scoping the
engine, it is important to check cylinders 4, 5, and 6 as bank two
always scores first. The engine needs to be bore scoped from the sump with the
piston at top dead center, since scoring always starts at the bottom of the cylinder. Checking
for scored bores with the spark plug removed and the piston at bottom dead
center isn't always effective in identifying early cases of scored cylinders.
Besides bore scoping, used oil analysis can identify increased aluminum and silicon content
which are good indicators of cylinder bore wear.
What does bore scoring sound like?
Before the bore scoring issue was a known issue, it was common for the
ticking sound created by scored cylinders to be misdiagnosed as bad lifters.
That is why it is very important to bore scope any engine if scored cylinders
are suspected rather than assuming this ticking is bad lifters.
Can bore scoring cause misfires or a CEL/MIL check engine light?
When bore scoring has progressed to significant levels of oil consumption of
a quart in 200 miles or less, it is common for the spark plugs to be oil fouled.
If enough oil is burnt, excessive amounts of carbon will build up on the pistons
and chambers, effectively raising the compression ratio, which can cause
detonation and rod bearing damage. Furthermore, carbon soot contamination of the
oil will cause damage to other engine components and cause timing chains to
stretch an fail, just to give one example.
What is a D-chunk failure and can my Boxster, Cayman, or 911 engine suffer from cracked cylinders?
Although D-chunks failures occur most often
on 99-01 3.4 996 engines, any M96 or M97 engine can have cracked cylinders. Like
with bore scoring, 2.5 and 2.7 base Boxster and Cayman
models do not suffer from cracked cylinder bores or d-chunk failures. 996 and
997 bore scoring is a much more common mode of failure than cracked cylinders on
3.6 and 3.8 models.
What is a slipped sleeve failure?
In the first few Boxster and 996 production years, the company that cast the
engine blocks
had some supply issues, requiring some engine blocks to be sleeved by the
factory. These blocks were bored out to accept a metal matrix composite sleeve.
Sleeves were located and retained by a small lip at the surface closest to the
cylinder head. Over time, the sleeve can come loose and the sleeve can fracture at the lip.
When this occurs, the sleeve is dragged towards the crankshaft and if the piston rings get caught
on the fractured lip, the top of the piston can be ripped off, resulting in a
catastrophic engine failure.
Can direct plating the M96/M97 engine block with Nikasil plating be used to correct for cylinder bore scoring?
With aircooled Porsche engines, the factory Nikasil plated cylinders can be
stripped and replated when bores are beyond their wear limit. Likewise, Alusil
cylinders used on 2.7 and 3.0 911 engines can be repaired using Nikasil plating
as well. Technically the M96/M97 engine can be reconditioned with Nikasil
plating, however there are limits to what the Nikasil plating process can
correct. Bores that are heavily scored have to be bored out then plated back to
size, however there are limits to how thick the Nikasil plating can be applied.
Normally Nikasil is applied .004-.006" thick per side. The Nikasil plating also
won't prevent future cylinder issues from cracking or d-chunk failures. Also,
the longevity of the repair is only as good as the parent metal that supports
the Nikasil bores. Knowing the engine blocks can and do go out of round,
suffering from ovality and taper issues even with low mileage, sleeving of these
engine blocks is the only proper solution to correct for scored cylinder bores,
cracking, and d-chunk failures.
Why don't conventional cylinder repairs work on M96 engine blocks?
In a normal engine, manufacturers supply oversized pistons and provide a procedure to overbore and hone blocks when they need to be reconditioned. With a hypereutectic engine block, further steps are required to do the required exposure process for the silicon particles and the pistons used have to have the required iron coating on them, meaning aftermarket pistons cannot be used. In the case of the M96/M97 engine and all other Porsche engines using Alusil engine blocks, oversized pistons are not available and procedures have not been provided by the manufacturer. This requires that blocks are replaced, sleeved, or direct plated to correct for cylinder wear or failures.
We have seen many engine blocks come to us over the years with a single sleeves fitted after a scored bore, d-chunk, or cracked cylinder occurred, but only to have another cylinder fail only months later. Likewise, direct plating of the bores can correct for ovality and taper, however it doesn't prevent a future cracked cylinder failure. Sleeving is the only way to ensure you do not have a future cracked cylinder.
However, not all sleeves are created the same. There are two types of sleeving - dry and wet. Dry is where a thin wall sleeve is pressed into the original cylinder after it has been slightly bored out to accept the repair sleeve, with some having a lip at the top and some being a straight sleeve. This is similar to what was done by Porsche on the blocks that suffer slipped sleeves. A wet sleeve is one where the sleeve sees contact with engine coolant and requires the original cast in cylinder sleeve to be machined out of the block. Due to dissimilar alloys and differences in expansion rates between the sleeve and aluminum block, both wet and dry steel or cast iron sleeves have to be installed with an interference fit. Too much interference and the block can crack or if too little interference fit is used, sleeves can move around, resulting in head gasket failures and intermix. Once the block's parent metal is cracked, it can't be cost effectively or safely repaired and must be replaced.
Another issue many do not take into consideration is that the M96/M97 engine, as all other hypereutectic engines, are all-aluminum. These engines were never designed to be fitted with steel sleeves where other aluminum blocks used by import and domestic manufacturers came with steel sleeves fitted from the factory. As you can see below, an engine with steel sleeves requires larger water jackets and increased cooling system volumes to make up for the loss of thermal conductivity. Aluminum has three to four times (3-4X) the thermal conductivity of cast iron. Add in an increase in displacement, and a steel sleeved M96 engine is already compromised, compared to one that is all aluminum. Putting a steel or cast iron sleeve into an aluminum engine block is a step in the wrong direction, using dated technology.
Nikasil has been used for decades because of its low friction and low wear properties compared to cast iron. Even in an engine with cast iron cylinders, a simple change of Nikasil plating the bores can result in a significant enough reduction in friction that many will see 8-10 horsepower increase alone. This also translates into lower oil temperatures as the friction between the piston rings and the bores are one of the largest sources of friction within an internal combustion engine.
Lastly, just as in an aircooled engine the use of aluminum cylinders allowed Porsche to increase the output of the engine without thermal overloading, the same goes with a watercooled engine. Case in point, when Porsche introduced the 944, a first for Porsche using an all-aluminum Alusil engine block, they were able to increase the output of the engine compared to the 924's cast iron block, all without sacrificing reliability. Steel sleeves, although inexpensive, have limitations including increased friction, reduced cooling, and shorter service life than our NSC-plated Nickies featuring all-aluminum construction. Why use anything less than the best?

986/987 3.2 to 3.8, 996/997 3.4 to 3.8, 3.6 to 4.0 101mm Nickies Closed Deck Porsche Engine Conversion
SKU: 106-996.101.CD
$5,032.36For many years, Porsche and other manufacturers have preferred the open deck configuration for their water-cooled, all-aluminum engines. This design enhances cooling, a critical benefit for high-performance engines, compared to the closed deck configuration. However, the open deck's main drawback is the potential for cylinder wall distortion and a decrease in overall rigidity, issues that have been notably problematic with the M96 engine. Nonetheless, LN Engineering's Nickies Porsche engine conversion employs a sleeving technique that maintains the open deck design for bore sizes up to 101mm, without sacrificing durability, strength, or reliability. This is achieved through the use of billet aluminum Nickies sleeves crafted from a special aluminum alloy. This material offers superior strength and thermal conductivity compared to standard factory cast aluminum cylinders. LN Engineering's Nickies cylinder liner sleeves have effectively addressed the weaknesses of the standard open deck design, boasting a successful history of nearly two decades with about 250 engines being sleeved annually through our unique Porsche engine conversion technique. Notably, the vast majority of Porsche engines modified by LN Engineering using our Nickies involve oversizes rather than the original bore sizes, demonstrating the effectiveness of our method in enhancing engine displacement and power well beyond the factory specifications of a Porsche engine. From the beginning, Flat 6 Innovations has exclusively employed LN Engineering's Nickies for all high-performance engine builds for Porsche Boxster, Cayman, and the 911 models 996 and 997, underlining the trusted performance and reliability of our big bore engine conversions. LN Engineering also provides closed deck engine conversions for Porsche Boxster, Cayman, and 911 models from the 996 and 997 series. While the majority of our clients opt for our traditional open deck Nickies Porsche engine conversions, which support displacements of up to 4.1 liters, there are specific situations where the decrease in cooling efficiency is considered an acceptable compromise for enhanced cylinder stability. For turbocharged Porsche engines, particularly those with M96 or M97 engines, a closed deck configuration offers advantages. Typically, we advise restricting the bore size to 99mm for supercharged or turbocharged Boxster, Cayman, and 911 engines equipped with Nickies. However, our closed deck conversion permits larger bore sizes up to 101mm, specifically tailored for forced induction setups. Additionally, for naturally aspirated engines requiring bore sizes greater than 102mm, we also offer closed deck conversions to maintain optimal strength and durability without compromise. Please call for pricing with pistons and for current lead time for our Nickies closed deck Porsche engine conversions. Learn More

$1,875.00
$1,500.00
Our cryogenic treatment service is recommended for all MA1/9A1 engine blocks used in Porsche Boxster, Cayman, and 911 models. Engine blocks that are cryogenically treated are more dimensionally stable and residual casting stresses are eliminated with this process that are usually the root cause of piston seizing and resulting cylinder bore scoring in these engines. Porsche 944/968 and M96/M97 engine blocks/cases/crankcase housings can be cryogenically treated for the same price. Please contact us for more information about having other engine components cryogenically treated.What are the benefits of cryogenic treatment of aluminum alloys?
Cryogenic treatment of aluminum alloys involves subjecting the material to extremely low temperatures, typically below -100 degrees Celsius (-148 degrees Fahrenheit), for an extended period of time. This process is done to enhance the properties of aluminum alloys, and it can offer several benefits: 1. Increased strength and hardness: Cryogenic treatment can lead to improvements in the hardness and strength of aluminum alloys. This is especially beneficial for applications where high strength and hardness are required, such as in aerospace and automotive components. 2. Improved wear resistance: Cryogenic treatment can increase the wear resistance of aluminum alloys. This is important in applications where the material is subjected to abrasive or erosive wear, such as in cutting tools or engine components. 3. Enhanced dimensional stability: Cryogenic treatment can reduce the dimensional instability of aluminum alloys, which is particularly useful in precision engineering applications where tight tolerances are required. 4. Residual stress relief: The cryogenic treatment process can help relieve residual stresses that may be present in aluminum alloys, which can improve the overall stability and performance of the material. 5. Increased durability and longevity: Cryogenically treated aluminum alloys tend to have improved durability and a longer lifespan due to the enhanced material properties. 6. Reduced distortion and warping: Cryogenic treatment can minimize distortion and warping during subsequent machining or heat treatment processes, resulting in better overall part quality. 7. Greater fatigue resistance: Aluminum alloys that have undergone cryogenic treatment may exhibit improved resistance to fatigue, making them suitable for applications that involve cyclic loading. 8. Enhanced electrical conductivity: In some cases, cryogenic treatment can improve the electrical conductivity of aluminum alloys, which can be advantageous in electrical and electronic applications. It's important to note that the specific benefits of cryogenically treating aluminum alloys can vary depending on the alloy composition, the treatment process, and the intended application. Not all aluminum alloys will respond to cryogenic treatment in the same way, so it's essential to consider the material's properties and the application requirements when deciding whether cryogenic treatment is beneficial. Additionally, cryogenic treatment is just one of several techniques used to enhance the properties of materials, and its effectiveness should be evaluated in the context of the overall manufacturing process and design considerations.Do other materials or alloys benefit from cryogenic treatment?
Yes, cryogenic treatment can be used on a wide range of materials and alloys beyond aluminum. While the specific benefits and effectiveness of cryogenic treatment can vary depending on the material and its composition, it has been applied to various metals, plastics, and other materials with the goal of improving their properties. Here are some examples: 1. Steel: Cryogenic treatment is commonly used for various types of steel, including tool steel, stainless steel, and carbon steel. It can enhance hardness, wear resistance, and dimensional stability. Tool steel, in particular, benefits from cryogenic treatment to increase its lifespan and improve performance in cutting and machining applications. 2. Cast iron: Cryogenic treatment can improve the microstructure and mechanical properties of cast iron, making it more wear-resistant and less prone to cracking. 3. Plastics and polymers: Some plastics and polymers can benefit from cryogenic treatment to reduce internal stresses and improve their dimensional stability. This can be useful in industries where precision and tight tolerances are crucial. 4. Copper and copper alloys: Cryogenic treatment can enhance the electrical conductivity and mechanical properties of copper and its alloys. It is often used in the production of electrical components and connectors. 5. Titanium alloys: Cryogenic treatment can increase the strength and fatigue resistance of titanium alloys, making them more suitable for aerospace and medical applications. 6. Nickel-based alloys: Materials like Inconel and Hastelloy, which are used in high-temperature and corrosive environments, can benefit from cryogenic treatment to improve their resistance to wear and corrosion. 7. Composites: Some composite materials, such as carbon fiber composites, can undergo cryogenic treatment to reduce internal stresses and improve their strength and stiffness. It's important to note that the specific benefits of cryogenic treatment can vary depending on the material's composition, its intended application, and the treatment process parameters (e.g., temperature and duration). Cryogenic treatment is often used in conjunction with other heat treatment processes to achieve the desired material properties. As with any material treatment, careful consideration of the material's characteristics and the intended application is essential to determine whether cryogenic treatment will be beneficial.
