QUICKBITZ in Dandenong, Melbourne, has earned a reputation for tuning and building some seriously quick street and race cars. They specialise in electronic fuel injection, wiring and setting up ECUs and tuning rather than fabrication and engine building, and have worked on a variety of cars over the years – everything from quick streeters to dedicated drag and circuit cars.

 We recently saw QuickBitz’s Stix (Michael Kalaitzakis to his mum) tune Bubba Medlyn’s Street Machine Drag Challenge-contending, twin-turbo Holden-powered VH Commodore to over 2000hp, which maxed out the hub dyno at the time. He also remote-tuned the VH at Summernats, where it made close to 2500hp to win the Horsepower Heroes dyno comp!

But QuickBitz initially made a name for itself by building quick sixes – mainly a lot of RB-powered VL Commodores back in the day, before moving into the 2JZ-powered Supras. QuickBitz actually has two Supra race cars, although one of them is powered by an unusual engine combo for the JDM icon.

 The Raceworks-branded Supra runs a twin-turbo big-block V8, which has run well over 200mph in the quarter on a radial tyre and deep into the fours across the eighth-mile. It’s a full-chassis race car with a Century block and twin 91mm turbos, with an eighth-mile PB of 4.30@182mph.

The other Supra is more ‘normal’ and powered by the Toyota 2JZ engine, and still retains the original factory front end. However, this one is still pretty wild, being a three-quarter-chassis, big slick-tyre car that has gone 7.00@200mph in the quarter and mid-fours in the eighth. The boys want to crack a six on slicks, then have some fun and stick it on radials.

The cool thing about QuickBitz is that it is one of the few workshops in Australia that can thoroughly test fuel injectors. After seeing some of the equipment that other workshops were using to test their injectors, Stix wasn’t convinced, so he decided to build his own injector testing bench powered by a Haltech Elite computer and a big mechanical fuel pump. With his set-up he’s able to flow-match injectors to within one per cent of each other, which is really unheard of. He says it really helps with consistency when tuning, because you know if there’s something weird going on in one cylinder it’s never going to be an injector issue.
