This is a complete performance rebuild on an S50. No expense spared, just about every part in this motor has been touched and freshened. This motor was built with ultimate reliability in mind, with performance bits added for good measure.
If you know anything about these motors, you know what it would cost in terms of time and money to do such a thorough build yourself. All external fasteners have been torqued striped for extra security.
