The stock I/C’s start to become inefficient after only a few modifications and increased boost. The best I/C upgrade that also fits in the stock location using the stock mounting points are these awesome units from GReddy.

With the stock Crank pulley weighing in at just over 7Kg this new Unorthodox light weight pulley weighs a little over 1Kg allowing for more potential BHP (less mass for the crank to spin). A very simple to install and cost effective modification, Twin turbo's will rev quicker, making for faster turbo spool up whilst normally aspirated Zeds will benefit with more low-end torque. For the purists, an over-drive water pump pulley is available which ensures that the water pump operates at the correct rpm when using an under-drive crank pulley. New ancillary belts are available separately (see the OEM section for prices).

They come with side skirt coating and in sizes 88mm(.040 over) and 87.5mm(.020 over).
Excellent value for money, these pistons have been used in many high powered Zeds around the world. When you rebuild your engine, you can rely on Wiseco.

A FULL Head & Main stud kit, all in one kit for the 300ZX. We HIGHLY recommend this kit to anyone wanting high BHP. It is just good engineering, the machine is only as good as the weakest component it is assembled with!! The studs are uniquely offered with Allen cut outs for the ease of installation and removal of the studs. This means the head studs and heads can be removed without pulling the motor. Reliability at it’s best!

Split Pipe Downpipes.....also known as divorced wastegates….
The reason this type of down pipe works better is because the exhaust coming off the turbo wheel is spinning extremely fast and whipping in a circle.  If the exhaust comes off the turbo wheel and enters a much larger area it becomes more turbulent, slowing the exhaust velocity; also when the wastegate opens, the two turbulent exhaust gases fight each other causing more turbulence.

NGK Platnium spark plugs are the OEM plug for the Nissan 300zx. They are ideal for all stock Zeds because of their excellent spark and longevity (60K). However they really perform at their best on modified TT's. The PFR6B-11B being a colder grade than stock and with the slightly longer shroud length to further reduce risk of detonation are not openly available within the UK and were mainly sold for the US market.

A newly developed ignition tuning system exclusively designed as a Performance replacement to the OEM Coil pack system.

It’s main features are:- Increases power and Torque, Surpresses drop down of secondary ignition, decreases ratio of incomplete combustion events, can improve fuel economy, can improve emissions and with easy installation. Full set of 6

These NEW Performance Fuel Rails will fit the OEM newer style of injectors (pintle-less) or Sard style injectors into either style lower intake pre or post 94 model Until now it has been difficult to install the newer style pintle-less OEM injectors on an earlier model Z32 replacing the old pintle type injectors. It involved considerable labour to complete this conversion involved not only removing the intake manifold to access the fuel rail and injectors, but removal of the timing belt and most of the front of the engine to remove the lower intake. The lower intake is then removed and sent off for machining to accept the later style fuel rail.

300 Degree have developed these rails to make this upgrade simpler. These rails avoid all that additional labour and expense. These rails will adapt the pintle-less injectors to the early style lower intake directly.

Options available, please advise when ordering. Many types/models of Injectors to suit also available. All rail kits now come complete with the 300 Degree fitting kit making installation very easy.

300D-012-01 fits Sard/PE injectors (commonly sold as 850cc/min) onto an early model(90-94) lower intake.
300D-012-02 fits Sard/PE injectors onto a late model(95-96) lower intake.
300D-012-03 fits OEM/Nismo pintle-less injectors onto a late model (95-96)lower intake.
300D-012-04 fits OEM/Nismo pintle-less injectors onto an early (90-94) model lower intake

AEM’s Plug & Play Engine Management System (EMS) will forever change the way you look at and perform fuel injection tuning! This user-programmable system plugs directly into the 300ZXs factory ECU harness and requires no additional wiring or hardware.* Windows™-based software (2000, NT, 98, 95, ME) makes the task of copying,

Viewing and manipulating data as simple as a click of the mouse. User-defined templates are easily configurable and enable tuners to establish "quick keys" to any pertinent information during the tuning process. The AEM EMS’s infinitely adjustable software allows tuners to program virtually any combination of engine control, power adders and auxiliary devices, and accurately deliver proper amounts of fuel and correct ignition timing for ANY boost level or operating condition. Easily mappable by many tuners throughout the UK.

Optional extras:-

Built in Wideband 02 sensor £180
5 Bar Map sensor £105
Air Temp sensor £60
