or 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.

This is the ultimate headgasket kit to lower compression on your stock E36 M3 motor. Have a built motor with stock compression and want to go FI? No problem! This is your solution instead of having to purchase new lower compression pistons.
Best of all, now you have another option instead of having to use an MLS gasket to obtain thicker headgaskets sizes. No more MLS woes where boost constantly leaks between the layers or between the cylinders. Our copper spacer / cutring headgasket combo has been proven to hold in excess of 30psi boost and is the only gasket kit we recommend when trying to lower compression from 10:5:1 on your stock E36 M3 motor to a more boost friendly 9:1, or for your M50/52 motor to lower stock 10:0 compression to a boost friendly 8:5:1… Hundreds sold!
CNC’d out of Billet Steel and ceramic coated for Ultimate durability with machined ports like a tubular manifold for incredible flow. It’s the best of both worlds without having the risk of cracking like a tubular manifold will. Turbos that have been test fitted range from the Garrett GT/GTX35R size, to the Precision 67R size and Precision Gen2 7285 CEA, to the Borg Warner 8374 EFR and 9180 EFR turbos with up to a 1.45 AR exhaust housing.
This manifold will also allow for clearance of the 8374 and 9180 Internally wastegated Borg Warner EFR turbos for those who wish to run an EFR turbo with this manifold and not have boost creep issues.
Competitively Priced versus other Twinscroll manifolds that also require dual wastegates and extra piping.
