PORSCHE BOXSTER & CAYMAN 2.7 L REBUILT ENGINE - YEARS 05-08

PORSCHE BOXSTER & CAYMAN 2.7 L REBUILT ENGINE - YEARS 05-08

Our engine rebuilds are thorough and extensive.

The 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.
 

Pistons are checked and Rings are then changed, Connecting Rods and Crankshaft are checked for tolerance specs.
 

Upgraded Main & Rod Bearings. Available only at Vertex Automotive

The Rod and Main bearings are replaced with EPS bearing shells that are 15% wider than stock, for a stronger and more durable bottom end. The main bearing shell at the flywheel side is replaced with the EPS Wider Double Friction shell for stronger crank support. This is an industry first and is only available at Vertex Automotive 

The Oil Pump is reconditioned and scavenger pumps are checked and replaced if necessary.
 

We then address the infamous IMS and permanently correct it using the revolutionary ETERNAL FIX by EPS

The IMS is machined for larger cylindrical roller bearings, (ETERNAL FIX).
The IMS is then modified for front oil pressure feed to the IMS bearing (Patented)

Why do we use the ETERNAL FIX with Cylindrical Bearings with Thrust Control?

Cylindrical Bearings have a very high load-bearing capacity, 5 times more than Ball Bearing. Cylindrical Bearings are used in, High Temp & Low Viscosity Lubrication such as Automatic Transmissions. They can carry extreme lateral pressure without wear to the friction surfaces. This is because the bearing friction surface is flat and not concave.

ADDITIONAL REAR MAIN #8 BEARING SEAL AND HOUSING

Our team of technicians has developed a Rear Main Seal that corrects the notorious rear main oil leaks on the m96 and m97 engines. It has been developed to solve the twisting of the last journal of the crankshaft, reducing engine vibration and extending engine life. Prevent engine failure, by replacing your factory rear main seal with our upgraded rear main bearing seal and housing.

Features:

- Prevents crank warping
- Decreases engine vibrations
- Prevents piston rod #8 failure
- Extends engine life
 

Cylinder Head Rebuild Process

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 Professional and Expert Porsche Specialists.
