The LMA265-FIAMINI is the perfect blend of modern performance and period-correct aesthetics. Designed specifically for historic racing, this unit provides the world-class reliability of a CNC-machined Denso alternator while maintaining the classic look of a traditional Lucas ACR unit.

Product Specs

• Construction: Full CNC billet housing with a shot-peened "cast" finish
• Aesthetics: Black powder-coated rear cover to mimic original Lucas styling
• Internals: Uprated OE Denso parts, anchored to resist harmonic vibration
• Pulley: Over-sized, high-sided, hard-anodised pulley (pre-fitted)
• Compatibility: All BMC A-Series engines (Classic Mini, MG Midget, etc.)
• Standard Output: 50A (90A High-Output available by special order)

Why Choose the LMA265-FIAMINI?

• Historic Legal Appearance: The shot-peened finish and black cover provide a discreet, authentic look for period-correct engine bays.
• Extreme Weight Saving: The smallest and lightest ACR-profile alternator available, reducing front-end mass.
• Race-Proven Security: The high-sided pulley prevents belt shedding at high RPM, even during accidental over-revving.
• Modern Reliability: Denso internals ensure consistent charging and durability that original 1960s/70s units simply cannot match

Design Note: This is the ultimate "stealth" upgrade for the serious historic racer who needs modern charging performance without compromising the car's vintage appearance.

[LMA265 is the latest development introduced in 2019. This is the smallest and lightest Lucas ACR direct replacement alternator in the world with a full CNC billet housing coupled to brand new and uprated OE Denso parts anchored in place to withstand any harmonic vibration.]

[LMA265-FIAMINI has had some tweaks with the historic racer in mind. The billet case has been shot peened to give it a cast aluminium appearance and the rear cover is powder coated black to resemble the black cover on an original Lucas unit. Supplied as standard with an over-sized, high-sided, hard-anodised pulley to reduce load on the engine and prevent the belt from turning or coming off if the engine is over-revved.]

[Available in 50A as standard or 90A (high output) as special order.]

[Also suitable for any BMC A-series engine including MG Midget.]
