Bimmer Performance Center delivers BMW engine programs that start with objective measurement— not parts lists. Every build is blueprint-verified, clearanced to intent, documented, and validated under load before you take the keys.
From forged bottom ends for boosted S55 / N54 platforms to high-RPM S65 refresh, closed-deck strength solutions, rod bearing lifecycle resets, and precision VANOS & timing system renewal—our process is structured. We mic, dial bore, profile, and record baseline geometry; specify piston-to-wall, ring end gaps, bearing oil clearance, thrust, and deck finish to target use (street endurance, track days, high boost). Torque / angle logging, fastener stretch (where applicable), dynamic & component balancing, oiling passage verification, and leak-down confirmation are embedded steps—never afterthoughts. Contact Us to start a spec discussion or convert an existing motor to a proven configuration.
*Lead time varies with machining queue, component sourcing (OEM / forged internals), and optional upgrades (fueling, head work, coatings). A formal timeline is provided after measurement & parts confirmation.
