We also work closely with our in-house engine build shop, so if you’re after more than just machining services and require a full build we can help.

BMW s54 cylinderhead from Hack Engineering MachineShop

As seen above a BMW S54 cylinder head, we see these on a regular occasion and we have built many of these in-house ranging from standard road engines right the way up to fully forged, forced induction, big horsepower monsters.

A full strip-down and ultrasonic clean are followed by a pressure test to check that the cylinder head is in good shape. if required we will then reface the head using either a PCD or CBN cutter. Following this all valve and guide measurements are taken and the cylinder head is built  back up to its former glory.
