BMW N55 S55 Engine Machining - Bore / Hone / Closed Deck Insert

£500.00

If your building your engine you may be thinking of boring your cylinders out to accept a larger piston, this will remove any damage or marks on your cylinder walls and leave it with a perfectly straight bore the the correct surface finish to bed in your new piston rings.

If you have an N55 engine you may also want to think about having our 'closed deck' insert fitted which can help increase block strength if your building your engine for higher power.

Please note, if the engine block is not completely stripped there will be an additional charge for stripping/rebuilding.
