This guide will touch on some of the specifics required when you build an N2x engine block.

(The N2x Platform shares around ~80% of its engine parts with the N55 and about ~60% with the S55, the N2x also shares some similarities with the BMW Prince Engines (N14, N18 etc)).

Please note, below information is an additional guide - this should be used in conjunction with the BMW N20 / N26 rebuild guide located in either BMW TIS/ISTA or equivalent.
