Base Shims

Custom Cylinder Base Shims/Gaskets for LN Engineering Nickies Cylinders

LN Engineering offers copper base shims/gaskets for Porsche 356/912 and Porsche 911 engines for select slip-fit and machine-in Nickies cylinders in thicknesses from .010" (.25mm) to .040" (1mm).

 

How do I determine what thickness base shim I need for my Nickies cylinders?

Base shims are not included with Nickies cylinder sets. The engine must be mocked up to check how much shim is required under each cylinder to correctly set your deck height. Most engine builders recommend a .040-.060" (1.0-1.5mm) deck height.

 

Do I need to use sealant on base shims?

Yes. Sealant should be used on the cylinder bases and base shims. Many engine builders have their own personal preference, however we use and recommend a non-hardening Curil T sealant, or alternatively Curil K2 on cylinder bases and base shims/gaskets.

 

Can I use more than one base shim on each cylinder when setting my deck height?

No. Only a single shim should be used. Our base shims are laser-cut or water-jet out of precision copper shim stock here in the United States, so custom thicknesses are available by request and take approximately 2-3 weeks for delivery.
