Despite its Datsun-era name, South Bay Datsun Auto Repair on Chula Vista's Broadway has serviced all makes and models since its 1997 founding, with particular depth in Nissan and Toyota drivetrains. The shop handles timing-belt replacements, fuel-injector cleaning, and full transmission servicing — the mechanical complement to the new-vehicle sales and OEM parts inventory at Mossy Nissan Chula Vista. Carburetor rebuilds for pre-OBD-II Datsun 240Z, 280Z, and 510 models remain a core specialty, drawing vintage-Nissan owners from across San Diego County. Modern diagnostic work covers OBD-II code pulls, oxygen-sensor replacements, catalytic-converter efficiency tests, and ECU reflashes for post-2000 vehicles. Complex drivetrain jobs route through the same Broadway service network that includes AAMCO Transmissions & Total Car Care for torque-converter and valve-body rebuilds. The facility's most involved procedures include complete Nissan KA24DE and SR20DET engine swaps with standalone ECU wiring, exhaust fabrication, and California-compliant CARB E.O. catalyst installations.
