Cylinder Head

BMW makes their cylinder heads from aluminum. While this is beneficial for many reason, they do not react well to overheating. Especially prevalent on older BMW engines, and over-temp situation has been known to cause the head to warp. Turner Motorsport carries Genuine BMW replacement heads and parts to make your next rebuild a success.

One major hurdle for a track-only car is the limitation of the hydraulic valve lifters in the M50, S50-US, M52, S52-US, M52TU, and M54 engines. These effectively limit your revs to 7200-7300 RPM as the valves 'float' at higher revs, leading to piston-valve contact. By converting to a machined solid lifter, and upgrading other areas of the engine, you can configure the valve train to withstand high RPM running. Not only can you tune for more power, you can help prevent damage during a mild mechanical over-rev.

This kit includes the mechanical spacers to convert hydraulic lifter tappets to solid lifters. The lifter bucket remains in place with the Schrick solid tappet replacing the original. These work on all M50, M52, S50, S52 and M54 engines and were proven in normally aspirated as well as supercharged engines. A custom camshaft is required.

Professional installation and setup is mandatory as these require complete assembly of the head, checking valve lash, then dis-assembly and machining of the Schrick tappet to spec. This kit includes enough spacers for 24 valves. We also carry individual parts, if you are looking for single pieces. This price is for a full set of 24.

A common issue on N54 motors is cam bearing ledge scoring due to lack of lubrication, and if left unattended can cause damage to the camshaft and increase oil consumption. These WPC-treated cam bearing ledges help prevent lubrication issues to ensure no scoring occurs on the bearing ledge or camshaft. What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both.
