Car Review: Hill Climb Championship winning, FJ20 powered Mallock

Instead of just doing a write up on a historic NZ car, I thought I would combine a car review as well. This car is a very special car and is the current Duncan Mackenzie hill climb champion. The Mallock also holds the record for the fastest time around the Port road street sprint track which is quite a feat.

This car is owned and built by Tim Sillay. There is a bit of a back story behind the construction of this Mallock, it all started off after the 2009 Duncan Mackenzie hill climb series with Tim tied for the series when at the Wallaceville hill climb, Tim went off the hill backwards in fourth gear in his Nissan 240RS. This completely totalled the 240RS and Tim vowed that he would never race again. Six months later after a lengthy period of recovery, Tim decided he would build the Mallock. He bought the plans and components to build the Mallock and embarked on building what is possibly the ultimate Mallock sports car.

The car is powered by a Nissan FJ20 twin cam straight four motor that is normally found in cars such as the DR30 Skyline RS, S110 and S12 Silvia's. This particular engine is putting out 230 BHP and 160 LB/FT which is great considering it is naturally aspirated. The engine breathes through twin side draft carburretors and features a lovely tubular exhaust system. This is backed up to a 4 speed Ford Escort gearbox and diff.

Cooling is taken care of with a large radiator and oil cooler that are mounted by the front diffuser to allow air to pass through them.

The Mallock is made up of a tubular chassis with a lightweight fibreglass body that simply bolts on. The front nosecone and rear wing supports are made out of carbon fibre which adds to the car only weighing 550 KG dry and 637 KG wet. Suspension is double wishbones at the front with a Mumford 4 link rear end with pullrods and rockers.

The wheels are 13 inch 4 spoke alloys that are shod with super sticky Michelin Pilot Super Sport's. The black wheels are a nice contrast to the yellow body. Braking comes from AP Racing 4 pots all round.

Inside the snug fitting cockpit is a small racing steering wheel with an electronic HUD display and a carbon fibre bucket seat with safety harnesses. A roll bar protects the driver from any accidents that may occur.

Tim has been experimenting with the aerodynamics of the car and has got a flat underbody with front and rear diffusers and a wide rear wing.

Overall, this Mallock is one awesome racing car that is perfect for it's intended use as a hillclimb and sprint car. I would like to thank Tim Sillay for allowing me to review "the most winningest" car in the Hutt Valley Motorsport Club.

Thanks for reading!!!
