Bmw M20 Roller Cam Conversion kit
M20 Roller Cam kit
No more worn cam lobes or broken rockers. This kit is proven to be extremely durable and reliable for sustained high RPM. Roller cams offer superior valve opening speeds and allow a more aggressive profile with higher lift that will increase power output potential while maintaining good low end drivability and idle quality. Needle bearings and rolling contact lowers the friction loss in your engine and reduces the load on your cam belt. There is simply nothing better!
Every item in this kit is made from the highest quality materials and products available. Cams are made in Sweden from high grade case hardened tool steel and ground on one of the most hi-tech cam grinding machines available, one of very few in existence that can produce the unique inverse lobe design needed to make this conversion work so successfully. Valve springs are high quality German Eibach and supplied with case hardened base locators and super lightweight titanium retainers. Rockers are precision machined to incredibly tight tolerances from high tensile 7 series aircraft aluminum and fitted with genuine Porsche valve lash adjusters and Swedish SKF needle bearings. Serviceable pins and rollers are made from crome-based bearing steel then case hardened and center-less ground to a mirror finish.
