MAZDA 626, 5-spd manual

In its standard trim the 2.5-litre V6 Mazda was not a very pleasant car to drive. Plagued by flat spots - at 5750, and between 6600 and 6750rpm - it was lumpy and rough, unresponsive and very harsh.


10% more power, 8% more torque - that's the claim, but more significant is the improved smoothness of the engine and the lack of flat spots. Again, attention has been paid to improving throttle response and getting the air/fuel mixture right. A

track, thanks to good throttle response which allowed the car to be driven through the corners. The car was very disappointing with the standard chip fitted - the engine was rough and noisy and suffered from noticeable flat spotting

at crucial points, particularly when changing gear.

The addition of the modified chip smoothed out the engine, got rid of the flat spots and changed the car's characteristics almost totally. It became pleasant to drive and much more responsive. Over the Standing Quarter the car showed a significant improvement in the wet with the chip fitted - compared with the standard car's time in the dry! (Each way runs).

Bear in mind, this car had nothing but a chip changed - standard air filter, standard exhaust!

NISSAN 200SX SPORT TURBO, 5-spd manual

The 200SX is one of the few things Nissan has done right in Australia in the past few years. A pretty little car, it offers a nice combination of style, performance and balance. It has proven to be a popular import for Nissan and performance modifications for it are keenly sought. In the 'Sport' package, the SX runs premium unleaded fuel, direct from the factory.


Because of the turbo, Power Chip developed a unique package for the SX. It comprises an additional small computer (not a plug-in chip) - the Powerchip FCD - which links into the car's existing system to alter the boost signals. Then there's an electronic boost controller - the Powerchip EBC - which

meters the boost being delivered, ensuring fast response down low and controlled boost higher up. The car was also fitted with a sports air filter.

The combination smooths out the application of boost, providing a much more pleasant, controlled power curve which is far more 'user friendly' than in standard form.

The result of the Powerchip rework is an increase in maximum power from a standard 147kw to a healthy 168kw. Torque is also increased, from 265 to 287 Nm across a much wider rev range.


The transformation of the car, after fitting the Powerchip modifications was nothing

short of sensational. The combination of increased turbo boost and the benefits offered by the EBC showed up immediately both in the straight line runs and on the track.

Acceleration was much improved in gears, the changes were much smoother both up and down and the whole feel of the car was altered for the better.

Throttle response - and turbo cut in - in the gears showed a vast improvement.

Against the clock, the SX showed terrific improvements compared with the standard chip - slicing more than a second off the 60-100km/h and 80-120km/h brackets.
