BMW série 3 E30 323i HARTGE H26
1984 BMW 3 Series 323i Hartge H26
Motors Corner is pleased to present this BMW 323i, upgraded to Hartge H26 specifications. Originally from France, it is registered with a "collector" vehicle title (*carte grise de collection*). The car underwent its full Hartge conversion in 1989—the year it passed the official French *Mines* inspection—which validated its compliance and resulted in the stamping of its official serial numbers. An appraisal from 1989 also confirms that a comprehensive anti-corrosion treatment was applied to the chassis prior to that date. Its identity and administrative status have thus been established and documented since the beginning.
The car has covered 130,000 km, with a consistent mileage history, and has been with the same owner since 2015. It has always been garage-kept. It comes with its original owner’s manual, the original radio manual, a full set of technical inspection reports, a 2025 appraisal, and a complete file of invoices dating back to the car’s origin, totaling several thousand euros.
Mechanicals:
The M20 six-cylinder engine produces approximately 190 horsepower, thanks to the Hartge modifications. The H26 cylinder head features polished ports, larger-diameter valves, and reinforced valve springs, paired with a Schrick camshaft. The intake system has been completely rebuilt; the engine is equipped with a Hartge valve cover and a reinforced oil pan, as well as a manifold cover, a performance exhaust manifold, and a full stainless-steel exhaust system with a Hartge silencer.
The transmission consists of a five-speed manual gearbox with a "dog-leg" (inverted) sport shift pattern, paired with a limited-slip differential (3.23 final drive ratio). The chassis is fitted with front and rear Hartge strut tower braces and a set of Bilstein B6 shock absorbers. The car sits on four Hartge alloy wheels, complete with their center caps.
Maintenance is up to date, with a continuous service history documented by invoices. The engine underwent a full restoration in 2021, including resurfacing the cylinder head, replacing piston rings and connecting rod/crankshaft bearings, and servicing the fuel injectors. The timing belt—along with the tensioner, cylinder head gasket, and spark plugs—was replaced in 2024; the transmission and differential oils were also changed. The alternator was replaced in 2023, and the clutch in 2016. Routine maintenance, including oil and oil filter changes, has been performed annually. The car is ready for the road.
Interior:
The cabin retains its original plaid-patterned fabric upholstery, which remains in excellent condition. It features a full suite of Hartge components: a four-spoke steering wheel, a gear shift knob, a driver’s footrest, and a Hartge-branded instrument cluster with a speedometer calibrated up to 260 km/h (instead of the standard 240 km/h). The center console houses gauges for oil pressure, oil temperature, and water temperature.
Exterior:
The bodywork was completely repainted in 2024, a detail confirmed by a 2025 professional appraisal. It is equipped with a full Hartge body kit—comprising a front spoiler, side skirts, and a rear valance—along with Hartge decals on the side skirts, side stripes, front and rear Hartge badges, and a rear spoiler. The car is also fitted with a sunroof. Technical specifications:
