The ASNU range of Performance Injectors offer the user a complete and unique range of injectors with various flow rate options and spray patterns.
All designed to suit the varied Motorsport and Street Performance applications.
With the range of Electrical Connector Adapters and Hard Wire connectors, combined with our range of Fuel Rail Adapters and reducers, there is an ASNU Performance Injector to suit most applications.

Correct Delivery – Maximum Performance – Minimum Fuel Wastage.
The ASNU seven hole orifice cap gives the ideal combination of Fuel Flow, Fuel Distribution and Fuel Atomisation. The seven holes produce smaller fuel droplets that will burn more efficiently, meaning more performance and more laps for less fuel. This is a critical factor and should be considered when comparing ASNU injectors to some other “Performance” injectors.

Achieving the designated BHP does not mean you will achieve maximum performance from the engine. ASNU Performance Injectors will allow you to maximise the power curve of the engine, give instant throttle response and maximum fuel economy, all required to win races.

Correct combustion is not about how much fuel you put in the engine, its about how efficiently you get the fuel to burn and that alone will determine the combustion performance of the engine. The option of having just ONE Injector and Fifteen Flow& Spray options to “select ‘n’ injector” from, gives the expert Engine Management System Programmers and suppliers the perfect answer to meet theirs and their customer needs.

With one range of injector resistance and impedance settings for all injectors, the only requirement being the mapping for the fuel flow rate and injector off-set. Simply Select you Injector requirements and plug & play.

Certified Injector Performance Testing
ASNU Performance Injectors have been designed for efficient high end “Performance” delivery that will also allow low end “OE” driveability, making them suitable for Street and Track applications. Motor Cycle & Marine use basically the same injectors for their applications, so the ASNU Performance Injectors are equally suitable for Performance upgrades on these systems.
ASNU’s world renown Injector Testing & Servicing System gives the ASNU Injector Distributors and their customers the guarantee and service that no other can offer. Every injector is Tested and Matched for Fuel Delivery, Fuel Distribution & Atomisation before they are released to the customer.
ASNU’s World Wide Injector Testing & Servicing Network means that injectors can be checked by other ASNU owners, anywhere around the world, offering a unique Service and Support Programme to the end user that no other injector supplier can offer, ANYWHERE! No more guess work about the performance of the injectors you are purchasing, you now have ASNU INJECTORS.

This allows an additional 6 ASNU injectors to be fitted to the standard inlet manifold. Kit comes supplied as a 3^rd rail & base plate, 1050cc injectors, injector driver, GTR specific loom for secondary injectors & machining instructions for the stock manifold. Upper rail and base plate are manufactured from 6082 alloy and the injector driver contains tri colour LED status indicator to advise when the unit is ready for action and advise of faults.

A machined inlet manifold can also be supplied on an exchange basis as an optional extra

The wait is over! ASNU’s 1500cc high-impedance injector is here!

The long awaited ASNU 1500cc high impedance performance injector, produced exclusive for ASNU by Bosch Germany, is now available after extensive development including overcoming multiple re-design challenges and exhaustive OE-spec endurance testing.

At 1650cc/min this Bosch EV14-based injector:
• is the highest flowing high impedance performance injector compatible with ALL fuels,
• can be driven with the saturated drivers found in every OE ECU and most aftermarket ECU’s.

Equipped with the stainless alloy valve found in all Bosch injectors produced for gasoline applications, this injector will be compatible with MTBE race fuels like Q16 and VP Import. In addition the ASNU 1650cc injector won’t be susceptible to the internal rust issues found in natural gas injectors, which occur when the water attracted by alcohol fuels separates causing rust that seizes the injector internals.

After passing multiple rounds of endurance testing in Bosch’s primary injector production plant in Germany, ASNU’s 1650cc high impedance performance injector has now been allocated an official Bosch OE part number along with its ASNU90/2000 part number.

We’re proud to say that our years of involvement in this project with the excellent team at Bosch in the Bamberg, Germany plant has brought us a purpose built injector to offer the performance market. This injector will certainly set the bar a notch higher. We also hope this will discourage owners from using other injectors that are not designed for performance gasoline applications.” says Phil Ellisdon, owner at ASNU.

With flow capacity of 1500cc/min or more at 5 bar (72.5 psi), this ASNU injector promises to be a great solution for performance motors running a variety of fuel systems.

This new ASNU 1500cc/min will be distributed internationally in two versions:

1. ASNU 1500 which will feature ASNU proprietary diffuser plate system offering the best cone shape atomization and fuel droplet distribution of any performance injector anywhere near this flow rate.

2. ASNU 1500, which is the same base injector without the ASNU diffuser plate, producing a less atomized spray pattern resulting in a narrower spray angle due to the unrestricted annular flow around the bottom of the injector valve (as is found in many other brands of performance injectors that are based on similar Bosch technology).

Due to its compact size, this injector will be available for all types of cars and engines, including the 53mm length as found in the Nissan R35 GTR and Mitsubishi Evo X, the often challenging 38mm “shorty” injector fitment of the Toyota GT86/Scion FRS/Subaru BRZ or the LS3 /LS7 from late model GMs, and also the traditional 64mm full length EV1 format which is still found in many cars today.

The ASNU 1500is available immediately, with the ASNU90/1650 and 1200/1300/1400/1500cc versions with a diffuser plate based cone spray pattern becoming available in the near future.

FP330E E85 Fuel Pumps – The ASNU FP330E fuel pump is a high output, in-tank, electric fuel pump that fits most popular EFI applications and has the added bonus of being Race Fuel Compliant.. The FP330 is a compact, lightweight pump and does not require any modications to the system; you simply unplug the existing pump and replace it with the FP330. This pump is ideal for applications requiring more flow while retaining the factory lines and mounting provisions available in the OE configuration. These pumps are suitable for Pump Fuel, Race Fuel & Ethanol E85 ** and flow 330 lph @ 3 BAR. Component wise they have Carbon Commutators and Carbon Graphite Bushes. All pumps are serial numbered for peace of mind and tested before shipping.

Direct Replacement for Nissan R35 GT-R

Part No: ASNU 92/FP330E

Due to the age of vehicles in the field we are now seeing blocked or heavily restricted filter in the stock cradle and the amount of time spent using E85 or other fuels with a high Bio component. This results in “drop in” pumps not giving the expected flows or even failing prematurely.

To combat this issue we have designed and tested a system that is as plug and play as possible. it only requires that you strip the filter and pump basket unit from the fuel module and replace with our kit

It is able to take stock or drop in replacement pumps all the way up to a pair of Walbro 450
We manufacture for the kit pump two different pump mounts accommodating pumps from the stock size all the way up to Walbro 450 units allowing you to use any of the common upgrade pumps for the stock unit from ourselves or other suppliers

We have superior flow over the standard design, due to a improved module lid with enlarged fuel entry slots and improved scavenge fittings with lower pressure drops,. This in turn means the pumps do not suffer from fuel starvation at full flow due to restrictions in fuel entering the module. Retain The factory surge tank is retained as a stock component to avoid issues with low fuel level pick up problems.

The factory level sensor and tank top plate are retained minimising the time and complexity of the installation

To allow the main fuel lines to be changed to motorsport style fittings then we can also supply in addition to this kit , a replacement tank top plate with -8AN feed and -6AN return fittings in a high flow design maximising the flow
If running the upgrade top plate, we can also supply a lift pump kit for twin lift pumps mounted on the side of the fuel module for race or high lateral g applications
The Baby battleship “bare” is the system without pumps for those who already have upgraded parts in there standard module or are looking at a cost effective replacement filter system for stock and just want the frame, scavenge system and filter – the standard Bare system comes with 39mm diameter pump mounts for stock or OE replacement parts

The bare system can also specified with a 41mm diameter pump mount that will accept the larger up- rated pumps such as the ASNU 340 family and the Walbro 450 series

The Baby battleship “660” is the system pre assembled with a pair of ASNU 330E ethanol compatible 330 l/h fuel pumps with the same filter assembly module, module lid, hoses and spare filter.

The kit is a designed to be practical alternative to changing the main filter over at the main 60,000 mile service without purchasing a whole new fuel module from Nissan for well over 1000USD .
This makes the kit a cost effective service replacement part for a filter change for those running higher mileage stock vehicles.
However the system is designed with higher performance and durability in mind and as such has a number of bespoke parts and features.

The kit utilises a custom filter housing with twin -6AN inlets and a -8AN outlet
The filter comes fitted with a 6 micron glass fibre wound filter. This allows full ethanol compatibility & optimal injector protection, whilst still retaining high flow figures & minimal back pressure.
One replacement filter is supplied with the kit & replacement filters are available on request, as are specialist filters for alternate fuels, if required.

The Fuel line used on the kit is tested to a working pressure of 10bar and is a nylon style unit similar to the original. This allows all fuel compatibility and the hose will not rot or degrade like rubber.

Lines from the pump to the filter are 8.3mm id , with a stainless steel crimp fitting at one end for the pump, and a high flow -6 AN fitting manufactured by XRP at the filter end.
From the filter to the tank top we use a 9.5mm id hose with a -high flow -8AN fitting again from XRP at the filter end, and stainless crimp at the other to allow it to mate with the standard Nissan tank top plate.

The kit uses the original pump pre filters, scavenge lines, return line and scavenge regulator, surge tank housing, tank top plate assembly, and wiring.

The module Lid is redesigned for improved flow over the stock unit and is shared with our 1100 l/h fuel system. It is manufactured from 316 Stainless steel for maximum durability. Threaded inserts allow simple assembly of components when in tank further enhancing use friendliness during install

The Filter is retained with a single band clip allowing simple assembly without tricky clips or screws and can be accessed with a simple flat bladed screwdriver from outside the tank

Component parts are manufactured from a 6062 alloy or from stainless steel and will not be affected by any fuels. Lines will not rot or fail (unlike rubber) and are rated for pressure in excess of the OE lines.

Filter life

For kits using the standard OE pumps, the filter should be inspected for debris build up every 12 months, and changed every 3 years or 30’000 miles.
For kits using the ASNU 330 E pumps or similar up-rated units, the filter should be inspected for debris build up every 12 months, and changed every 2 years or 20’000 miles due to the significantly increase flow of the up rated pumps.
If used in competitive events or with race or mixed fuels the element should be inspected every 4- 6 months and changed as required.

Plug & Play Flex Fuel Kit
The kit utilizes a Ethanol Content Analyzer and super slim Ethanol Content Sensor.

The Ethanol Content sensor mounts on the firewall and is connected to your fuel system by two stainless PTFE fuel lines.

The Fuel dampener easily accessible and attached to the back of your fuel rail by two 10mm bolts will need to be swapped out for the one that’s included in this kit.

Everything plugs directly into the secondary air pump plug which is located next to the battery.

Our rail allows for the retention of your stock rail mounted fuel damper which is required to reduce fuel rail pressure pulses when running large injectors with non standard pump systems. The rail also retains the OE injector harness mounting tabs for a professional appearance.

Boasting an internal bore of 17mm, and an impressive capacity of 170cc (over 11 times that of the stock rail) this gives the rail the capacity to supply even the largest of injectors.

The rail is supplied with -8AN feed & -6AN return fittings and a high flow & lightweight transfer hose from BMRS. Machined from grade T6082 aluminium and finished in a hard anodised coating, this rail will meet the requirements of top tuning specialists both specification and aesthetics wise.

R35 GTR rail fuel pressure and temperature sensor upgrade.

To allow accurate information relating to both fuel pressure and fuel temperature to be fed back to the ECU for accurate compensations on the main fuel map, ASNU have developed a fuel pressure and temperature upgrade kit for the ASNU R35GTR fuel rail.

This allows the ecu and your tuner access to live data on the fuel in the rail for an improved tune and setting safe limits for high temp operation, especially useful in hot climates where fuel temperature is critical to engine life at high load .

The ASNU sensor kit uses a single high quality Bosch sensor combining a calibrated fast reacting fuel pressure sensor head with a reaction time of less than a millisecond along with a highly accurate temperature sensor with a low thermal mass for fast response.

EcuTek software allows for calibration of the pressure sensor and the temperature sensor is designed to replace the stock tank fuel temp sensor input to the ECU.

The sensor comes in an alloy fitting block that mimics the OEM Rail fuel pressure damper. The alloy housing has a small amount of movement to allow for non stock manifold assemblies.

It can be fitted in replacement for the stock pressure damper in the ASNU R35 GTR rail and comes with connector pins, waterproofing seals and rubber boot. This allows it to be connected to either the redundant boost sensor from bank 2 or bank 2 HFM air mass meter (if using speed density)
