Whether it’s bringing a cylinder block back to life or machining performance upgrades, the Fiennes Performance team have a decade of experience in cylinder block engineering on hand. 

Cylinder block services include the rebore, resizing and honing of cylinders; bore sleeving, including counter bore machining, cam line machining, line boring; crankcase performance modification, acid dips (carbon removal) and the re-machining of the block and gasket faces

As a final check we carry out pressure testing for flaws. Having sealed all the water jackets to give us an airtight seal we can detect even the most minute imperfections by forcing through a maximum air pressure of 20psi, delivering peace of mind before an important track or race day.
