The LMA265-RACEMINI is the ultimate "no-compromise" alternator for performance A-Series engines. Combining a stunning CNC billet housing with uprated OE Denso internals, it is the smallest and lightest Lucas ACR direct replacement currently available.

Product Specs

• Construction: Full CNC-machined billet aluminium housing and cover
• Base Unit: New, uprated OE Denso internals for maximum reliability
• Pulley: Over-sized, high-sided, hard-anodised pulley (pre-fitted)
• Compatibility: All BMC A-Series engines (Classic Mini, MG Midget, etc.)
• Weight: The world's smallest and lightest ACR-style replacement
• Standard Output: 50A (90A High-Output available by special order)

Why Choose the LMA265-RACEMINI?

• Vibration Resistant: Denso internals are anchored specifically to withstand the harmonic vibrations found in high-revving race engines.
• Race-Optimised Pulley: The large-diameter design reduces parasitic engine load, while high sides prevent belt loss during over-revving.
• Premium Aesthetics: Features a gorgeous raw CNC finish and aluminium cover—perfect for show-standard engine bays.
• Modern Efficiency: Latest-generation internals offer far superior charging stability compared to traditional Lucas units.

Design Note: This unit is a direct replacement for the standard Lucas ACR footprint, making the upgrade to modern charging technology simple and effective.

[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-RACEMINI is very similar to the FIA model but is left in it’s gorgeous CNC machined finish case and aluminium cover. 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.]
