Toyota Supra MKIV JZA80 2JZGTE and Toyota Aristo 2JZGTE Top Feed High Flow Aluminium Fuel Rail Kit from Tuning Developments!

Manufactured from high quality aluminium, fitment is perfect to both the cylinder head and also the injector seals, meaning no bad fitments and importantly no fuel leaks! Whilst allowing the conversion over to top feed injectors for your 2JZGTE engine build.

Tuning Developments have perfected the design over time and this Toyota Supra, Aristo high flow rail is larger than the stock fuel rail found on the Toyota Supra or Aristo 2JZGTE engine. This in turn gives a more even flow of fuel to each injector and ensures that each cylinder is fed a more equal amount of fuel, meaning the engine runs more efficiently and smoother!

For big power setups this high flow uprated fuel rail from Tuning Developments is highly recommended. We have tested this fuel rail over 700bhp so far with excellent results. On top of all this, did we mention that they look excellent in any engine bay! Whats not to like?! Anodised finish in either blue, and supplied with fitting hardware.

The Tuning Developments Uprated Fuel Rail is designed to work with an aftermarket fuel pressure regulator only, this will not work with the standard Supra or Aristo Fuel Pressure Regulator, for those people who don't already have aftermarket regulators these installed, we can supply and/or fit these. Please see our other items or give us a call on 01925 822 266 to discuss further.

Injector Dynamics ID1050X 1050cc Injector Set (6 Injectors) - To Suit all 2JZGTE Engines

ID1050X - Nominal Flow Rate - 1065cc/min

*Dynamic flow rates measured at 3.0 Bar (43.5 psi) Using Gasoline at 52 Degrees C (125 Degrees F).


Application specific fitment is handled with the addition of various top hat adapters, and occasional machining operations. Standard fitment exists for most popular applications, and new fitments will be developed on request. All standard lengths and fuel rail bores are currently accomodated.

Dynamically Matched Sets:

We only sell matched sets, and within each set the dynamic flow rate (slope) will vary no more than +/- 1%, and the dead time (offset) will vary no more than +/- 20 microseconds which is equivalent to +/- 1% at a pulsewidth of 2 milliseconds.

It is this dynamic flow matching across the pulsewidth range that separates the men from the boys.

Tight matching at low pulsewidths allows the use of high flow rate injectors without sacrificing idle, off idle, and cruise quality while the matched offsets insure that the individual injectors respond properly to atmoshperic and voltage compensations built in to the ECU.

Full Dynamic Characterization

We provide the data that you and your ECU need to do the job properly.

Flow and offset values are provided from 8 to 16 volts across the full pressure range in 5 psi increments.

Additionally, we publish full dynamic characterization curves: Raw flow vs pulsewidth, offset corrected flow, linearity curves, and pressure sensitivity plots.
