This page displays the Fuel Rails ASNU have on offer. Fuel Rails We have designed and manufactured Performance Fuel Rails for various applications to fit our ASNU Performance Injectors. These include top feed replacement rails, along with converting from side feed to top feed applications. Below is a selection of the current fuel rails that we offer: R35 GT-R Twin Fuel Rail Set (Part No: ASNU092/GTR-R35) The ASNU R35 GTR fuel rail is designed for ultra high-performance engines looking for that something extra to give you the edge. 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. Designed with upgrades in mind, the stock damper can be replaced with fuel pressure and temperature monitoring sensor kit with EcuTek compatibility. Boasting an internal bore of 17mm, and an impressive capacity of 1700cc (over 11 times that of the stock rail) this gives the rail the capacity to supply even the largest of injectors. It is designed to fit the OE injector fitment and of course the ASNU range of Performance Injectors. The rail is supplied with -8AN feed & -6AN return fittings and a high flow & lightweight transfer hose from BMRS. It is 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. The rail is supplied with -8AN fittings, and is not designed to plug and play with stock lines. We do not recommend running these rails with the stock lines! If you need to run our rails with the stock lines, then you will need to purchase our adaptor kit ASNU092/R35RegMount which consists of 2 of the parts shown below: SR20DET VVT Top Feed Conversion Rail (Part No: ASNU092/SR20DET) The system allows the conversion of a stock SR20DET manifold to top feed injectors without having to remove the idle speed control valve and keeping the original pipework. The rail is manufactured from 6082 aluminium and unlike our 1st generation rail, the new rail is machined from one piece and has standard –6 fittings on either end. The rail is supplied complete with manifold seals for the stock inlet (aftermarket manifold fitment is available at extra cost), bolts to attach to the manifold and an Aeroquip FC332 (or for an extra cost, we can supply a BMRS PTFE with stainless over braid) link pipe. Subaru WRX Twin Top Feed Conversion Rail (Part No: ASNU092/WRX1) The ASNU Subaru WRX 1 rail allows you to convert your EJ20 Phase 1, 1.5, or 2 engine from its’ stock side feed rails to more desirable top feed injectors whilst operating with the OE manifold. Due to the unique design, our rail is able to accommodate all of the early side-feed installations without additional plates or adaptors for the different phases. With motorsport in mind, it has been optimised for reduced weight without sacrificing reliability and performance; coming in at 520 grams including fittings manifold adaptors and bolts. The rails are able to accept the full range of ASNU injectors from 300 to 1500cc; giving an exceptionally wide range of flows and spray patterns and allowing you to optimise the injector to your requirements. Designed for minimum height from the cylinder head and reduced length on the rearward end of the rail to improve clearance on the intake housing for large turbos. For maximum turbo clearance, it can accept a special swept fitting incorporating a 90-degree elbow (this is not included as standard in the kit). Specifically designed to optimise the injector location for maximum performance when used with ASNU injectors. They are able to flow up to 1000L/h with minimal pressure drop, in twin feed centre return configuration; giving guaranteed fuel supply capability up to 1500HP. Due to the improved flow of the rails beyond the capability of the OE regulator, our rails require the use of an up-rated remote mount fuel pressure regulator. The fuel rail is manufactured from high strength billet T6082 aluminium alloy and is supplied with industry-standard -6AN to AN6 ORB fittings to safeguard against fuel leaks even at high pressures. The fuel rail spacers are manufactured from acetyl tubes to minimise heat transfer from the engine to the fuel rail. The rails are supplied with stainless steel bolts to avoid both surface rust and galvanic corrosion. 2JZ VVTI Supra Top Feed Conversion Rail (Part No: ASNU092/2JZ) We are pleased to announce we now have ASNU 2JZ VVTI Top Feed Conversion Fuel Rails available! After working closely with our machine shop, and some of our Performance team, we now have a top feed fuel rail conversion for the 2JZ VVTI engine found in the MK4 Toyota Supra. This fuel rail is designed specifically to work with our ASNU Performance injectors and will allow you to run ASNU Performance Injectors that can be built to suit from 300cc up to 1500cc. Our fuel rail comes with the manifold adapters required to work with our ‘A’ cap fitment injectors, along with upright fittings and AN8 to Orb8 fittings to attach to custom fuel lines. The rail also has a centre port with a blanking plug, giving you the option to have twin end feeds and centre return for high power applications or retain the blank for standard use. We also have plug and play harness adapters as an optional add-on if you are not changing your injector harness loom Part No: (ASNU090/HA013)

Information on the different types of injectors we offer here at ASNU and links to different vehicle manufacturers and the injectors we offer for their different models. ASNU Performance Injectors ASNU have over 30 years of experience with injectors from all the various injector manufacturers worldwide. ASNU is represented in over 38 different countries, with thousands of injectors being tested and serviced in Aftermarket and Motorsport worldwide; a programme and experience unrivalled by anyone else in the world. This gave ASNU the greatest experience and understanding to develop a range of performance injectors that will do exactly what they are designed for - Correct Performance. ASNU Performance Injectors are purpose-designed and built with the ideal spray pattern to match the flow required. They are designed to meet the varied demands of the Racing & Performance markets, with the largest range in the world! ASNU DNA Tuning Data Read More Injector Fitting Instructions Read More Choose Your Manufacturer Nissan Mazda Lexus Mitsubishi Ford Toyota Porsche Honda Subaru Vauxhall BMW Opel All ASNU Performance Injectors have a multi-hole orifice cap, cut using the latest laser technology for greater accuracy and repeatability. Using this technology allows us to produce injectors with specific spray patterns and flow rates to meet the customers' exact requirements. The seven-hole orifice cap that we use in most of our injectors in the lower end of the range (300-1000cc) offer an ideal combination of Fuel Flow, Fuel Distribution and Fuel Atomisation. The seven holes produce smaller fuel droplets that will burn more efficiently, giving more performance and more laps for less fuel. This is a critical factor and should be considered when comparing ASNU injectors to any other Performance injectors. About Our Injectors All injectors are fitted with easy to see Flow Rate and Spray Pattern identification rings with the top ring indicating the Spray Angle and the lower (smaller) ring representing the Flow Rate. The image below shows the varieties of flow and spray colours. Each spray angle option is matched to the flow rate to ensure optimum usage of the fuel provided. Correct combustion is not about how much fuel you put in the engine, but how efficiently you get the fuel to burn and that alone will determine the engine's combustion performance. Achieving a designated BHP does not always mean that you will achieve the maximum performance of your engine. ASNU Performance Injectors will allow you to maximise the engine's power curve and give instant throttle response and maximum fuel economy. The ASNU Performance Injector programme offers the tuner/high-performance user a complete and unique range of injector options to suit their individual requirements and with our range of Harness Adapters and Fuel Rail Couplings, there is an ASNU Performance Injector to fit nearly every top feed application. ASNU Fuels Disclaimer ASNU fuel systems and injectors are designed to be used in conjunction with standard grades of road-pump fuels, and certain race fuels with lubricant and corrosion packs (please enquire for details of tested and compatible race fuels). The use of pure Ethanol, Methanol or other chemicals mixed in combination with standard pump gas or race fuels is not advised and will invalidate any warranty on all of our systems. Fuels with more than 50% ethanol, even with lubricants, will greatly accelerate wear and shorten system life as well as reducing the service life on any filters. Our products are compatible with certain methanol blends containing an appropriate lubricant pack and E85 for race or drag events. When used with fuels that have Ethanol contents over 50% or fuels with a methanol content, the fuel system must be drained and flushed between events to prevent irreversible damage.
