350z Twin Turbo - Speed Shop

Since the first release of 'the Z' in the early 70's, Nissan ignited the passion of performance enthusiasts who desired high performance, sharp handling and killer looks. The 350Z has now taken the Z legend to new heights and has produced what is arguably the greatest Z yet.

And now, the perfect partnership has been formed in order to take the 350Z to a performance level that will have thoroughbred supercars running scared. Drawing on over 20 years of turbo charging, supercharging, inter cooling and engine management system design and production knowledge, APS has created the ultimate High Output System for the Z's 3.5L engine.

Or to put it another way, just add the APS Twin Turbo System for an instant 150 hp adrenalin shot at only 8 psi of boost pressure - obviously the turbochargers are extremely efficient and under-stressed at this power level!

APS has designed and manufactured a custom configured, vertical flow high efficiency intercooler utilizing custom designed light weight cast aluminum end tanks. Extremely high flow rates and massive temperature reduction - a level of performance that other manufacturers can only aspire to achieve.

O.E. quality flexible air ducting connects the air cleaners to polished 304 stainless steel compressor inlet ducts.

The shortest possible routing, equal length, mandrel bent, polished 304 stainless steel ducting, connects the compressor discharges to the twin intercooler inlets. This contributes to the brilliant boost response of the APS 350Z turbo systems.

Custom turbocharger flanges in 304 stainless steel ensure bullet proof connection to each turbocharger and optimum air flow. In addition, ancillary connections such as those to the blow off valve and blow off valve return lines are positioned for optimum air flow so that the already crisp turbocharger response in accentuated during gear changes.

APS has designed, tooled and manufactured in high temperature resistant iron, cast exhaust manifolds and turbine outlets. Fabricated components simply look racy but for street durability in excess of 5,000 miles, castings are a must!

APS custom mapped Plug-In engine management computer for optimum engine tune/power

APS High Output Injectors with upgraded fuel supply. Includes a plug-in replacement loom - no cutting and soldering! High horsepower demands precise fuel delivery to each individual injector, particularly under demanding conditions such as drag racing and autocross.

The APS upgraded fuel system is a complete bolt-on precision fuel system that consists of a comprehensive range of components designed specifically to support huge horsepower and yet retain excellent fuel atomisation, fuel economy and driveability in day to day driving conditions.

The APS fuel system by far exceeds any fuel system found in other brands
TT systems for the 350Z - in fact, stands head and shoulders above the rest! A total package engineered for extreme performance in line with the APS philosophy of total system engineering.

APS Twin Cold Air Intake System
APS has designed and manufactured vehicle specific air cleaners that deliver a huge volume of cold air to each turbocharger. Most importantly from an air temperature perspective, APS has positioned them outside the engine compartment.

Unlike ram pods which source hot air from under the bonnet, the APS system breathes cool air from the inner guard for the optimum engine performance and durability. More importantly the air through the APS high flow air intake system is consistent in temperature. This means that the engine management unit's temperature compensation system operates correctly - unlike devices that source air from the highly turbulent areas under hood.

Each turbocharger is fed directly by it's own air cleaner element via highly polished 304 Grade Stainless Steel ducts in exposed / hot areas and polymer air ducts custom made to APS specifications for areas that are hidden from view. The APS polymer ducts are also totally dust / water proof and above all, provide a very durable and highly flexible connection between the air filter and stainless steel duct. Flexibility and durability are of utmost importance in this area as this allows for a great deal of engine movement due to high engine torque.

Air Cooled Cast Alloy High Capacity Engine Oil Pan
High engine horsepower demands the very best in lubrication, particularly when the Z is driven under extreme motorsport conditions such as Autocross, Drag racing and Circuit racing. In that light, APS has developed the ultimate engine oil pan that not only improves engine oil supply to the pick-up, but also increases the engine oil capacity by a huge 1.25 quarts. This alone reduces oil temperature and helps to protect the Z engine.





The APS High Capacity Oil Pan will be available this September and can be installed on normally aspirated, supercharged and turbocharged Z engines. Delivered complete with provision for twin oil return lines for turbocharged applications and blank-off plates when normally aspirated and includes detailed installation instructions.

With the huge air flow capacity of the APS turbochargers utilized in the APS Intercooled Twin Turbo High Output System, the unique APS High Volume Twin Vent Blow Off Valve delivers unsurpassed venting performance, excellent driveability and crisp turbocharger response in on/off throttle applications. A blow off valve is a device that releases pressure from the turbocharger when the throttle is released. It ensures that the pressure shock load on the turbocharger compressor is minimized and encourages each turbocharger rotating group to continue spinning during gear changes. This ensures that when the next gear is selected and the throttle re-applied, both turbochargers rapidly produce high boost pressure and strong torque.

With a large or twin turbochargers, releasing pressure from the turbine compressor wheel when the throttle is snapped shut is critical not only for lightning fast turbocharger response, but for turbocharger longevity. A huge volume of air must be passed through the blow off valve as soon as the throttle is closed.

Most blow off valves have limitations in their design that inhibit the level of performance demanded by APS. Piston/bore diameter and venting ports are often too small and surprisingly, most will not fully expose the exhaust ports when fully opened.

APS designed the APS high volume twin vent blow off valve specifically for the APS Intercooled Twin Turbo Z.

A mammoth 1.417" (36 mm) internal bore size delivers huge capacity and at full piston travel, all ports are fully exposed for maximum blow off volume.

The APS twin vent BOV features 30 micron hard anodized, T6 billet aluminum body, low friction bronze piston, all stainless steel hardware including spring and Viton 'O' rings.
