For the US E36 M3. Schrick 264/256 degree camshafts boost mid-high end power for that extra motivation at higher rpm. Low-end torque is not seriously affected due to the M50/M52s VAN0S System. And, higher profile cams work extremely well with an upgraded intake and exhaust. When upgrading the cams there are other areas you must take into consideration. Higher-flow fuel injectors, larger mass-air sensor, and custom programming are strongly recommended. Turner Motorsport sells complete intake & cam packages that boost power to over 290hp. See the Engine section under Camshafts for more info.

 

Cam Specs:
Intake - 264 degree, 11.2mm lift
Exhaust - 256 degree, 10.6mm lift

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.

These Schrick camshafts are the same specs as the stock US S50 cams -
Intake: 252 degree, 10.2mm lift
Exhaust: 244 degree, 9.5mm lift

With original S50/S52 cams in short supply, and a new set running over $2,000 from BMW, you can source new M3-spec cams from Schrick. These are the same specs as the US S50 engine and very close to the stock S52 cams. These make a great upgrade for M50 (325i, 525i) and M52 engines (328i, 528i) with the proper tuning. These bolt in just like the stock and M3 cams with no special hardware upgrades required - use your stock valve springs, lifters, etc. But for reliability we recommend replacing the lifters, valve springs, and retainers with new stock parts on high mileage engines.

BMW M5 Z8 S62 Solid Lifter Bucket - Priced Each is the ideal upgrade for enthusiasts looking to push the performance limits of their BMW M5 or Z8 with the S62 engine. Hydraulic lifters, while effective at reducing noise and maintenance, can become a bottleneck at higher RPMs due to their reliance on oil, which can slow movement and increase stored weight. By upgrading to solid lifter buckets from Turner Motorsport, you can achieve higher revs and unlock more power from your engine without the drawbacks associated with hydraulic lifters. This upgrade is crucial for those seeking peak performance and reliability.

  • Enhanced Performance: Allows for higher revs by eliminating the limitations of hydraulic lifters.
  • Improved Durability: Solid design reduces the risk of failure at high RPMs.
  • Precision Engineering: Turner Motorsport quality ensures a perfect fit for BMW M5 and Z8 S62 engines.
  • Optimal Power: Maximize your engine's potential with this essential upgrade.
  • Priced Per Unit: Allows for customized upgrades based on your specific needs.
