Priced as a set of 4. <br><br> <b>This is a cast replacement piston set for the M10 engine which may be configured to your specification</b> - select the desired compression ratio and cylinder head type using the options above. There is an approximate 2-week lead time to have the pistons machined for your custom application. <br><br> <b>Compression ratio:</b> Minimum configurable compression ratio is approximately 8.0:1. Maximum configurable compression ratio is approximately 10.5:1. Absolute minimum and maximum will be dependent on cylinder head type and choice of camshaft - please contact us if you have specific questions regarding your application. <br><br> <b>Cylinder head:</b> These can be configured for any M10 cylinder head - ie; 116,118,121,E12,E21,1.8, etc. These pistons may also be used for the M30 3.0 and 3.2l engines with stock 89mm bore diameter. Please specify your head casting type in the options above. <br><br> Piston weight will vary depending on compression ratio and cylinder head type to be used. Average individual piston weights are from ~520g to ~540g. <br><br> By default, these pistons will be shipped with standard piston rings. We can accommodate requests for custom piston rings on special request at additional cost. <br><br> Additional Features:<br> * Piston weight is very-close (within a few grams) of the factory piston.<br> * Standard BMW ring and wrist pin configuration.<br> * Skirts are coated for reduced friction and wear.<br> * Valve reliefs have been cut into the tops so higher lift cams can be used with no piston-to-valve clearance issues.<br> * These pistons can also be machined to fit the 3 liter and 3.2 liter M30 6 cylinder engines as well. <br><br><br> Note that we are stocking pre-configured 9.5:1 models of these pistons in popular head configurations for immediate shipment.
