Our Rebuild Process

The engine is stripped to bare components and put into a high pressure wash at high temperature with cleansing chemicals, this removes all carbon deposits and debris from previous failures. From this stage the cylinder bores and pistons are checked for cracks and wear tolerances. If your returned engine core requires cylinder re-sleeving this will be completed at an extra cost.

Upgraded IMS Bearing & Oil Feed Modification

We address the infamous IMS and permanently correct it using our revolutionary ETERNAL IMS Bearing and oil feed modification.

Unlike the other failure-prone ball bearing products that the original IMS and other upgrades on the market use, EPS uses a patented cylindrical bearing with thrust control that can be pressed directly into the back of the engine. The cylindrical bearings have over 12 times the load capacity of other ball bearing solutions making the EPS IMS bearing the clear choice.  

Additional Rear Main #8 Bearing Seal & Housing

Our technicians have developed a Rear Main Seal Housing (RMSH) that presses to the back of the engine. The RMSH adds one more main bearing for added support to the back of the engine. The additional rear bearing support prevents RMS oil leaks, premature #7 main bearing failure, cylinder #6 rod bearing failure, and twisting of the crank, extending engine life. 


 

Upgraded Rod & Main Bearings

The Rod and Main bearings are replaced with EPS bearing shells that are 18% wider than stock.  These large bearings have more surface contact area on the crank, making the bottom end of the engine stronger and more durable.

Rebuilt Cylinder Heads

Each cylinder head core is disassembled and inspected for broken bolts, stripped thread holes and broken mounting holes, etc.  All heads go through a three-step cleaning process which includes: 

1) Passing through a high temperature oven.  
2) Professionally bead blasted.  
3) Placement in a non-caustic hot tank.  

The Head is then inspected for cracks & pressure tested. Cam bores are checked for spec and honed if needed.   

The machining process includes;

-         Inspect valve guide bores using a dial bore gauge and repair where needed.

-         New OEM German Phosphorous Bronze Valve Guides & Valve Stem Seals are installed

-         All valve seats are cut, not ground, using three angle cuts for maximum precision.

-         The valves are inspected for stem and valve face damage and/or wear, as well as straightness. 

-         All valves are hand ground and/or replaced as needed.

-         Thoroughly inspect and test all of the valve springs for proper tension / resistance and replaced as needed.

-         All head surfaces are machined (milled), not ground!

Final head cleaning and assembly includes;  

Cleaning all heads in a solvent base tank in which all oil galleries, thread holes, etc. are cleaned.  A number of different brushes are used to catch any remaining contaminants.

All heads are run through a detergent based hot tank before assembly. All assembly work is done by hand by a professional Porsche specialists.
 

JE Pistons With Upgraded Piston/Cylinder Geometry

EPS Engines are rebuilt using high quality, specially designed J.E. Pistons. The piston skirts are modified specifically to prevent cylindrical scoring. The rist pin position is also  modified to improve the angle of the rod to the piston. This modification reduces piston to cylinder wear, extending the life of the pistons & cylinders. Reducing cylinder oval maintaining a round cylinder. Additionally, on the 3.6 litter engines we modify the piston/cylinder geometry to further extend the life of the engine.

Upgraded Steel Cylinder Sleeves

EPS engines are fitted with ductile cast iron sleeves. Ductile sleeves are the best type of cylinder sleeves available. Ductile iron engine cylinder sleeves are the standard in the high-performance engine world, for engine builders that are producing high horsepower and highly boosted engines that are generating a lot of torque.

Ductile Iron is a specific type of cast iron which has an addition of magnesium to it to make the graphite in it nodular. The nodules strengthen the material in a couple of ways. They add to the tensile strength of the iron and they also increase its impact resistance. Ductile iron also has an elongation factor in it that allows the material to “flex” somewhat inside the bore. This is the “bend but don’t break” advantage of ductile iron over cast iron in your cylinder liner.

Repositioning of the Oil Spray Diverter

The M96 & M97 engines suffer from upper cylindrical scorching on cylinders number 4,5,&6. This problem is caused by poor lubrication at the back of the piston. The EPS engine is modified so that the oil squirters are redirected and aimed to the proper lubrication area. 

Engine Reassembly

Using only Genuine German (OEM), the engine is reassembled to factory specs.

NOTICE: This Limited Warranty outlines your warranty rights and responsibilities and the rights and responsibilities of EPS.

INSTALLATION REQUIREMENTS AND RECOMMENDATIONS Your engine has been re-manufactured by precision workmen to rigid specifications and tolerances, using quality replacement parts. By following the steps outlined in this limited warranty, you can ensure your engine a longer, trouble-free life and protect your warranty.

STEP 1 : SELECTING YOUR INSTALLER This engine has been carefully re-manufactured to precision standards. If certain steps are taken by the person making the installation, it will perform properly. An engine is a complex component that requires a high degree of technical knowledge to install. Before an engine can be properly installed, it is recommended that the installer be ASE certified or have equivalent credentials. If a properly re-manufactured engine fails to perform satisfactorily, it can be due to detonation, pre-ignition or “lugging,” overheating or excessively rich air-fuel ratio, under-lubrication, dirt, coolant seepage, or ineffective air filtering. The above-mentioned reasons for failure are under the control of the installing mechanic/technician, and are not the responsibility of the engine re-manufacturer. Another important factor is that your installers have the proper engine diagnostic equipment. Be certain the equipment is capable of diagnosing emissions, ignition, fuel systems and in-vehicle computers and sensors. CAUTION: This partial list of recommended installation procedures and instructions are intended only as a guide. If you are not qualified to perform an installation, do not attempt it, as you may be liable for resulting engine failure. To avoid harmful contamination, thoroughly clean parts that will be attached to the rebuilt/re-manufactured engine. Also, any and all parts not included with a re-manufactured engine or engine component should be cleaned properly before installing on a new re-manufactured engine. Vehicle computers and the fuel injection system must be re-calibrated for the replacement engine. It is essential this be checked. Not doing this alone can cause your engine to fail. Look for a clean work environment at your installer. Cleanliness is essential in an engine installation. Neat and orderly shops often produce the best workmanship.

STEP 2 : REPLACING YOUR ENGINE • Check for freight damage or dirt contamination, which could occur during shipping. • Check application of product. Make sure the mounting holes, bell housing, crankshaft snout, flywheel mounting flange, bolt hole patterns, pilot shaft hole, smog/non-smog application, etc., are the same on new products as the old. • Clean all accessories to be transferred to the new product from the old one. Other procedures may be necessary to ensure proper engine operations. Other operating systems in your vehicle may need to be checked, particularly if they may have been responsible for or contributed to the failure of the original engine. The radiator may need replacing and/or cleaning. Air-filtering systems, pollution control components, sensors, injectors, and vacuum-operated devices may need attention as well as oil coolers. Rely on your installer for advice on these items. They have the expertise and equipment to properly diagnose and will do so as a matter of procedure. Do not take short cuts, as it will only cause greater expense and inconvenience in the future.

STEP 3 : REPLACING PARTS Replace recommended parts, and then follow up with your installer to thoroughly check other parts, which may have contributed to the original failure. Your re-manufactured engine should begin operation under the same conditions as the original engine. It is recommended that the below listed parts be replaced. Air Filter, Fuel Filter, Fuel Injectors. It is highly recommended that you thoroughly test and inspect the following parts and replace as necessary: Radiator Cap, MAF and MAP Sensors, All Hoses, Oxygen/Temperature Sensors, Throttle Position Sensors Now is the easiest time to replace these parts. If these replacements are performed now, future labor expenses and inconvenience will be avoided.

STEP 4 : CHECK-UPS For the first 200-300 miles, avoid sustained high-speed driving or carrying of loads. Avoid lugging the engine, and constant-throttle driving. A check up is required after the first 500 miles to protect your warranty. At this time check ignition timing and idle speed, inspect for oil and water leaks, general operation of the engine. Checks up costs are the responsibility of the vehicle owner. Please keep in mind, engine break-in will take upwards of 1000 miles.

STEP 5 : MAINTAINING AT REGULAR INTERVALS Perform routine maintenance on your vehicle on a consistent basis. Your warranty requires the below items to be performed for Basic Engine Maintenance. • Initial oil and filter change at 1 engine hour and again at 1000 miles following recommended break- in procedure. • Change oil and filter every 4 months or 4,000 miles. We recommend 10w40 Conventional oil. • Check fluid levels every gas fill up. • Change air filters every 25,000 (more often in a dusty environment). • Check belts/hoses at 30,000-mile intervals. • Tune-up, including spark plug replacement every 25,000 miles. Keep all maintenance records. We recommend that you keep all receipts and accurate records for maintenance work performed on your vehicle. In order to have repairs made under warranty, we require documentation of proper vehicle maintenance as outlined in Factory Warranty and Vehicle Owner’s Manual as well as the steps outlined in Step Four above.
