Instructions and Manuals for LN Engineering Products

Installing an LN Engineering or Bilt Racing Service product or rebuilding your aircooled or watercooled Porsche engine? Download instructions, manuals, and directives for free. In addition to the technical information available to download for free, be sure to check out the DVDs and Books from Bug Me Video and The Knowledge Gruppe as well as our product catalogs that go over our IMS, Nickies, Type 4 Store, and water-cooled programs for Porsche and VW engines and vehicles. These resources are designed to supplement and in some cases replace the factory Porsche service manual as a guide to maintain your vehicle and properly rebuild your engine from assembly to installation.

If you are looking for additional technical resources for your Porsche, we recommend publications put out by Bentley Publishers as well as those books written by Wayne Dempsey, Bruce Anderson’s Porsche 911 Performance Handbook, and even service manuals from Haynes. Although we don’t offer them for sale here, you can purchase many of these from Pelican Parts or Amazon, just to name a few.
