Infiniti G35 - APS Intercooled Twin Turbo

The Infiniti G35 ignited the passion of performance enthusiasts who desired high performance in a luxury sports touring vehicle. With similar engine and drivetrain to the Nissan 350Z, the Infiniti refines the Z's raw edge and adds a new dimension to the sports touring concept.

And now, the perfect partnership has been formed in order to take the Infiniti G35 to a performance level that will have thoroughbred supercars running scared. Drawing on over 20 years of turbocharging, supercharging, intercooling and engine management system design and production knowledge, APS has created the ultimate High Output System for the G35's 3.5L engine.

With insane horsepower and monster torque, the APS High Output System moves the Infiniti G35 performance enthusiast exclusively into the supercar club.

But best of all, the APS enhanced G35 delivers uncompromised driveability. Crisp throttle response, tidal waves of torque, silky smooth highway cruising and excellent fuel economy all add up to an outstanding daily driver - and at your whim, mash the pedal and unleash the beast from within.

In the tradition of luxury sports touring vehicles, the Infiniti G35 uses some components that are better suited to this application rather than those on the more raunchy 350Z. One example of this is the front nose cone/bumper assembly. The G35 employs a more streamlined and closed approach over the 350Z and through innovative ducting behind the nose cone, alleviates some of the restriction of air to the radiator such a closed approach has. The additional ducting however imposes some limits to the maximum engine cooling capacity, hence total engine power potential and to some degree is more applicable to regions that do not experience extremely high ambient temperature conditions (at elevated engine power levels). Under these adverse environmental conditions, APS recommends the replacement of the front nose cone with one that is more open in design to ensure the best possible air flow to the engine cooling system. In addition, vehicles that are to be subjected to sustained high engine load conditions (such as circuit racing), a replacement open design nose cone should also be considered.

APS has cleverly designed the APS Intercooled Twin Turbo system for the Infiniti G35 around the APS system to suit the Nissan 350Z - to ensure commonality of parts where possible - but with the important addition of a Supplementary Fitting Kit to address the unique requirements of the Infiniti. This delivers the most cost effective solution for the Infiniti G35 owner and broadens the market to cover both G35 and 350Z owners when the time comes to sell the G35 and return it back to stock specification.

On the road, the APS Intercooled Twin Turbo system is simply amazing. The acceleration from 2,000 rpm all the way to redline is just an awesome experience that only a few Twin Turbo Porsche owners have ever experienced in the past.

Best of all, in the higher gears, maximum boost pressure is available from an exceptionally low 2,500 rpm!

NOTE Auto Transmission Applicability Reference

  1. Physically fits
  2. Requires torque capacity upgrade by trans specialist

The APS Intercooled Twin Turbo system is available with one of two pre-programmed engine management strategies to suit either 91 Octane (R+M)/2 or 93 Octane (R+M)/2 fuels. The two dyno charts below demonstrate the difference in power output of the two different fuels:

The above dyno chart demonstrates the power at the wheels of the Infiniti G35 fitted with the APS Intercooled Twin Turbo system running on 93 Octane (R+M)/2 fuel - utilizing the APS 93 Octane engine management strategy.

Note - stock catalytic converters fitted & 4th gear (industry standard for the Infinity/350Z) power run.

Exclusive Cargo - Fast Fours June 2005

David Chambers' twin turbo Nissan 350Z is pretty close to what a lot of people may consider to be a flawless daily driver. It portrays the power and reliability of a European exotic and the road golding to match but at a third of the price.

APS Twin Turbo Nissan 350Z - Japanese Performance (UK) May 2005

Think the 280bhp, 3.5-litre V6 Nissan 350Z is a great car? Now try it with an APS twin-turbo conversion bolted on. The result: a 430bhp, 420lb ft supercar slayer.
