NiCom® (Nikasil®) Plating and Honing for the Porsche® 928, Cayenne, 944, & 951


Scratched and Damaged Porsche® ALUSIL® and NIKASIL® Blocks and Cylinders Repaired

We service the Porsche® 928, Cayenne, 944, 951, 911 and 968. Others by request.

TOP QUALITY: 928 Motorsports is a dealer for the US Chrome NiCom® repair system for Alusil and Nikasil blocks. Their NiCom® facility is literally just minutes up the street from our offices, providing the best service (ISO 9002 certified) you can get on your engine cylinders and blocks.

SCRATCHES vs. GOUGES: Scratched cylinder walls do not have to be the end of your engine. We can rebore, NiCom® plate them to build them up, and hone them down to final size. The finished cylinder wall is harder than the original, and will last longer. Cylinder wall scratches 0.10" inch deep or less will be removed by this boring, plating and honing process. Scratches deeper than .010" are considered "gouges" and they are too deep to remove. In this case, we recommend boring to fit the next over-sized stock or after-market piston. The process is the same after that.

WHAT IT IS: The US Chrome process is trademarked as "NiCom®", (because Porsche® holds the trademark on the term "Nikasil®") , but the process was brought over from the Mahle plant in Stuttgart and is identical to the quality and finish that Mahle performs for Porsche® on its OEM engines. There are a few other platers in the US that have an aluminum block plating process, but they do not deposit the density of 2 micron-sized carbide particles as NiCom® does, and the end result is inferior.

NiCom® is an electroplated nickel matrix with silicon carbide particles uniformly dispersed throughout. The carbide is extremely hard, but not abrasive because of its minute particle size, which averages two microns. The inclusion of these dense ceramic particles raises the hardness of the composite and provides unique properties, particularly when plated on aluminum. NiCom® has been found to be so effective that leading manufacturers (General Motors, Mercury, Harley-Davidson, Kawasaki, and others - see pictures below) are now using it on new cylinders as well as repairs.

Adding NiCom plating to your Alusil block provides:

  • SUPERIOR WEAR RESISTANCE - usually two to ten times that of chromium
  • EXCELLENT FRICTIONAL CHARACTERISTICS - less tendency to gall or seize
  • EXCEPTIONAL OIL RETENTION - due to the olephyllic nature of silicon carbide
  • GREATER THICKNESS - up to .015 are possible as compared to the normal range of .003 - .004
  • HIGH TEMPERATURE RESISTANCE - heat transfer for continuous service
  • GREATER RESISTANCE to scratching and abrasion that Alusil

OUR BLOCK REPAIR/PLATING SERVICE:
  • Ship your bare block to us at 928 Motorsports, LLC. Prepare your block by removing all the steel from it, like locating pins and head studs. Send just the bare block, no crank or rods installed. If there are steel parts in the block that you cannot remove, they will be removed for you but you will be charged extra for this service. The block does not have to be clean.
  • Send along one of the pistons that you plan to use. We can repair the scratched cylinder wall and return it back to OEM condition if you like for use with stock pistons, or we can bore your block out for use with aftermarket forged pistons. We will mic out the bores of each cylinder, and work with you to select the boring (standard size, or oversized) that you want for your application.
  • The price in this listing covers the standard 4-part process: 1) strip/clean the block with a series of baths in acids and cleansers and washes. This also etches the block for optimum adhesion of the plating. 2) Bore the block to your specs for the finished piston size you select. 3) NiCom plate the bores, and 4) Hone the cylinder walls with 10-bit diamond hones to your finished size. The special hone we use also leaves an excellent surface for oil cling to the cylinder walls - reducing friction and increasing engine life.

This is the special 10-bit diamond hone that will be used on your Porsche® engine. Common honing bits are 6 or 8-bit units. This 10-bit unit will produce a bore that is more perfectly cylindrical than others.

A WORD ABOUT PRICING: This process may look a little pricey - but if you check you will see that it is less than half the cost of purchasing a new block (if there is one available!) And small local machine shops cannot produce the NiCom® coating or the quality diamond finish honing you need. How expensive is a finished engine, assembled and in the car, that doesn't last? Now THAT's expensive!

THE WARRANTY: US Chrome and 928 Motorsports LLC® backs up all their work to you with a 1-year Limited Warranty.

NOTES:
*Boring will be needed if changing Piston size, or after welding up a deep gouge.

If welding a deep gouge is required, expect a welding charge of about $150 per cylinder welded.
