The holy grail of Holden Muscle Cars. The mighty HSV GTSR W1. A collectable classic from the get go. In stunning unmarked Heron White, GTSR W1 #88 is presented for sale with only 552 KILOMETRES on the clock. For sale from Perth, WA.

Only 298 of these ultra special Commodores were built, 275 for Australia and 23 for NZ. And to these, the last of the glorious Aussie Commodores, HSV fitted the monstrous ZR1 Corvette derived LS9 6.2 litre supercharged V8 pumping out 474kW or 636hp and 815Nm of torque.

But it is not all about the power. HSV engineers also blessed the GTSR W1 with some pretty serious performance kit.

A bespoke front-end accessory drive (FEAD) needed to be added to the front end to service the power steering unit and the engine needed to undergo extensive emissions calibrations to meet Euro 5, a task that had never been undertaken for the LS9.

The LS9 also uses a dry sump, which required a custom designed and built centre section to cater for the Commodore's engine bay. Unlike most cars on the market (the LSA-powered GTS and GTSR included) that use a wet sump oil capture and return system, the W1 uses a dry sump that sucks oil from the bottom of the engine ensuring that at race pace there is always oil in the engine.

The GTSR W1 also comes with a custom-tuned SupaShock providing a 220 per cent stiffer setting over the regular GTS or GTSR's magnetic ride control module.

HSV engineers also designed a carbon-fibre air inlet that runs over the radiator and is designed to offer a stable environment for incoming air that's also rigid and strong enough to deal with the pressures associated with the amount of air it's sucking in.

Unique to the GTSR W1 is a Tremec TR6060 MH3 close ratio six-speed manual transmission. The change to the TR6060 MH3 was required due to the extra torque produced by the LS9 - the GTS's gearbox just wouldn't cope with this amount of torque.

The GTSR W1 also uses a ZF Sachs twin-plate clutch that's more compact and lighter than the GTS.

Pirelli's PZero Trofeo R tyres are not designed for the wet - they even come with a warning to suggest you shouldn't use them in wet conditions. However, pin the throttle to the floor in first and then change hard into second and the tyres hook up perfectly and propel the GTSR W1 forward at spaceship-like pace. The grip is seemingly endless.

And when the bi-modal exhaust opens, everybody around you - even in surrounding suburbs - knows what's happening. The exhaust note then teams with the supercharger whine and the result is simply intoxicating!

This is an amazing standout car that truly celebrates local engineering and the passionate people who made this superb Australian muscle car a reality.
