Nizpro Turbocharging Workshop

About Nizpro

Nizpro, as the name suggests, was established to service the performance requirements of the Nissan car owner, with a specific orientation towards turbocharging.

From humble beginnings whereby all work was performed in a large home garage, the company quickly grew necessitating a move to a sizeable factory situated in the outer eastern Melbourne suburb of Bayswater.

Prior to the move, company principle Simon Gishus embarked on a lengthy planning exercise while adopting the policy that he would only invest in the highest quality equipment.

To this end, major renovations took place including the design and development of the companies own in-house engine dynamometer system. This incredibly sophisticated dynamometer incorporates a soundproof control room, soundproof engine room, and a massive 75,000-litre water supply system.

A chassis dynamometer was also installed along with an engine ‘clean’ room, large mezzanine storage facility, and two-story office complex.

Whereas the most significant emphasis has revolved around the Nissan product, with regularly changing trends the decision was made to expand and diversify the business to meet these needs.

Racecar preparation, although a component from day one, was broadened to include the ground-up building of various race vehicles, along with engine development for AUSCAR, V8Supercar, Nations Cup, GT Performance, Ski Boat and various other categories.

Moving Forward

In recent years, Nizpro has pooled almost all of its many recourses into developing a range of extensively road tested, dyno proven COBRA power-upgrade packages specifically for the awesome BA/BF XR6 Falcon Turbo and F6 range with no less than six incredibly comprehensive kits ranging in power outputs.

Succinctly, COBRA delivers with a range of XR6 Turbo Power Upgrade Packages to suit every need from plain fast to jaw dropping. Every COBRA kit from the base model on is supplied with every component required to ensure optimum performance, unsurpassed drivability (factory like smoothness), and optimised fuel consumption.

COBRA systems are by far the most stylish on the market, delivering an awesome visual ‘kick’ that will ensure crowds gather whenever the bonnet is opened. The next step is of course to impress onlookers or passengers with awe-inspiring performance.

COBRA delivers unsurpassed performance with incredibly flat high powered torque curves, while an incredibly efficient front-mount intake manifold almost completely eliminates inherent turbo lag, and in doing so provides throttle accuracy and response never before felt in an Australian produced vehicle.

By drawing on years of experience designing and developing specialised induction systems for various forced induction applications, when embarking on an all-encompassing XR6 Turbo development program, we purchased two ‘mules’ (sedan and utility) along with a pair of brand new 4.0-litre turbo engines. Having this amount of equipment provided us with the ability to run two separate programs at the one time; template design – kit construction, and perhaps more significantly, internal engine development.

The significance of the engine program is that the results allow us to establish effective parameters for all of our power upgrade packages. It’s all good and well bolting a range of parts on an engine, hence increasing power, however if an inherent engine design is not capable of sustaining these power levels with reliability, then the customer is ultimately going to run into trouble.

For example, whereas we have been able to run internally standard combos with flywheel power outputs of up to 400kW, having dissected a number of XR6 Turbo engines, we believe that for longevity sake (as opposed to throwing a rod through the side of the block thanks to inherently small connecting rods), once power outputs exceed approximately 360 kilowatts, we recommend fitment of our high strength H-beam rods.

Some may see this as overkill, however if we look back in history to the first 11 second VL Turbo, once Nizpro started to up the ante with power figures in excess of 300 or so kilowatts, we always fitted our engines with custom connecting rods. At that point in time many in the aftermarket suggested this to be over the top, yet history has proven that Nissan RB30 rods break under duress. So the question remains, will those who don’t equip their high-powered BA Turbo engines with quality connecting rods ultimately pay the price?

Ultimate Goal

In every area of expansion, the company achieved its ultimate goal; that of providing its customers with race winning service and products, and quality back up service.

We are proud of what the company has achieved over the past 12 years and look forward to future challenges.
