"Nothing is impossible"

Here is one of the most popular choice with which we have large amounts of experience:

The OPTI

This is an optimised standard engine (part-number 115000, 115100 or 115200), overhauled to BMW tolerances.
The crank (crankshaft & flywheel) is balanced with the piston and connecting rod weights to within 0,1g.
The volume of the combustion chambers are measured and matched as required.
This results in a mechanically quieter engine.
A further stage would be to decrease the valve gear noise.
One-piece rocker spindle supports in conjunction with needle bearing rocker arms would lead to a quieter head.
