 High Boost Cut Ring Head Gasket E36 BMW


High Boost Cut ring Head Gasket E36 BMW


This custom designed cut-ring gasket kit will allow for boost levels in the +30 psi range, without the additional hassle of having to machine your block for orings or to fit pyramid rings. Simply lay the hg down like a stock gasket, and then place the rings on the block.  When you lay the head down, the cutting grooves on the rings will cut into the head creating a tremendous seal.  The cutrings act as a barrier protecting the hg material from combustion and seal the vulnerable between the piston wall clearances notorious for blowing MLS head gaskets constantly.


The latest version of this hg designed by Athena and now imported by JE ProSeal includes newer style cutrings that have a triple groove cutting surface (vs. the older style we used to use with only 1 cut groove) for maximum sealing. This head gasket can support both M50/52 motors and S50/52 motors up to 87mm bore built motors, so please let us know what size you need.  Offered in oem thickness, but can also be paired with our custom designed copper spacer to lower compression to 9:1 on stock compression motors.


Does NOT damage cylinder head when cutrings cut into the head.  These grooves are very slight and are machined out during cylinder head re-decking... the same amount which would have to be re-decked for an MLS headgasket to seal properly with a flat surface.

 CES Copper Spacer Gasket E36



CES Copper Spacer E36 BMW


The copper spacer gasket we offer is heat treated and annealed to be super soft and malleable to help with sealing, especially if surfaces are not perfectly flat. These copper gaskets are used by top fuel dragsters  for their durability and sealing properties that are far superior to normal gaskets.


For use when paired with the high boost cutring headgasket on stock compression S50/52 E36 BMW motors to lower compression to a safer 9:1 for  higher boosted forced induction applications above 10-12 psi.


This is the ultimate upgrade for lowering compression on a stock bmw motor or built stock compression motor, and far superior to MLS that are prone to failure and leaking between the layers, especially at highetr boost levels.


Have a built motor but stock compression pistons and don't want the hassle or expense to have to replace the pistons with low compression ones?  Combine this with a cutring gasket as a combo we offer!
