ASNU Classic Injectors ASNU are just finalising the design & manufacture of replacement injectors for OE applications that use Bosch D-Jetronic injectors that are now no longer produced. This will keep historic vehicles on the road without the need to spend thousands on updating their fuel system and management. More information on this product range will be available very soon.

Manifold Upgrades ASNU R35 GT-R 12 Injector Conversion Manifold Part No: ASNU92/R35GTR C/KIT ASNU has developed an injector conversion kit for the R35 GTR to allow an additional 6 injectors to be fitted to the stock manifold. This was originally prototyped in conjunction with the highly respected tuning software company Ecutek to develop software strategies for 12 injector control. Allowing up to 1400hp the stock manifold is far from restrictive. With the injectors giving up well before this, we decided that what was needed was a properly engineered upgrade for the stock manifold to allow you the option to run a second set of injectors. Upper fuel rail and lower mounting plates are manufactured from aircraft-grade T6082 billet aluminium and are then bolted and bonded in place before the fuel resistant epoxy is oven cured to ensure maximum strength and durability. The injector placement and additional injectors have been optimized for maximum power and torque as they are only expected to operate at the higher engine loads. ​ The injectors have been specially developed for this installation and are of the same ASNU SC family originally produced for the World Rally and World Rally Cross championships that flow between 300 and 1300cc static flow at 3 bar. This is on top of your existing injector flow and if run in conjunction with an ASNU 1050/14 in the primary injector location, it will allow a total of over 2600cc of fuel at 3bar fuel pressure per cylinder. To guard against potential boost leaks, additional parts are bonded in place using a specially formulated fuel (and Ethanol, Methanol) resistant epoxy. The fuel rails are manufactured with a -8 (17.5mm ) internal bore to allow maximum fuel flow. The 12 injector conversion is supplied with a loom and bespoke additional driver, allowing the driver to control the additional injectors. It works in conjunction with the ASNUR35GTR fuel rail and sensor options and is designed to be as near to plug and play as is possible at this level of engine modification. The design has been tested for bonnet clearance on both stock and a number of aftermarket fiberglass and carbon bonnets so fitment issues even on non-standard panels are not a problem.

Machines - The ASNU Piezo Box Diagnosing Injector Performance Piezo injection is the current system of choice of major executive vehicle manufacturers. Piezo injectors can respond so quickly that they can allow the vehicle to run at incredible air/fuel ratios of up to 60:1 in some engines. Compared to standard vehicles running at 14:1 air/fuel ratios, this means the minimum amount of fuel is used and the exhaust emissions are virtually non-existent, while still maintaining excellent drivability and performance. As you can imagine, the performance of these injections is critical, maintenance should not be an option, it should be mandatory. How often do you check your Piezo injectors? In conjunction with a world-leading vehicle manufacturer, ASNU has created this purpose-built adapter box.​ Easy to use test functions using the latest Piezo technology Easy connections to Classic GDi Machine or GDi adapter Box. Universal fittings for Piezo type injectors Dimensions: 300mm x 190mm x 220mm in a robust metal casing.

< Back ASNU 66W Wire GDI Filter Basket Laura Bonafont 23 Sept 2020 ASNU 66W Wire GDI Filter Basket We are recommending that anyone testing and servicing GDI injectors, namely theBosch HDEV5 variant that take the slim 4.7mm filters, to switch to the ASNU 66Wfilter. We have found many of our customers seeing injectors with damaged standardinjectors due to chemical cleaning and additives (which we highly recommendagainst!) as they destroy the standard plastic filter baskets (which can in turn gothrough the injector!). Our ASNU 66W are a wire filter basket that are more hard wearing and what wewould recommend as the best replacement for these injectors. They are now back in stock, sold in packs of 50 pieces. Please contact your local ASNU distributor for pricing Previous Next

Injector Fitting Instructions/Assembly Guide Fuel suitability ASNU injectors are designed for operation with gasoline based fuels up to E98, and are able to operate long term on fuels containing MTBE or ETBE. For other fuels such as Methanol-M100, please contact us to discuss suitability, as alternative seals and O-rings may be required. Assembly It is necessary to lubricate both the upper and lower O-rings and any manifold seals before installation into both the engine and the fuel rail. We recommend the use of a clean, non-silicon based motor oil. Ensure the oil does not contaminate the internals of the injector or the spray plate assembly. For certain turbocharged applications, the sealing tolerances for the injector to manifold/cylinder head have been changed to ensure a leak free installation at higher than stock boost levels where the OE seals can cause leaks. If, during maintenance, the injectors are removed and are to be refitted, fresh O-rings should be used. Spare O-rings can be purchased from ASNU’s approved Distributors or Service Centres . Installation When fully assembled into a cold engine, the injector must be free to rotate around its’ axis with a small amount of longitudinal movement (0.5 to 1.5mm). This ensures that the injector is not damaged by over compression when thermal expansion of the injector and related engine components occurs. We advise checking your fuel rail manufacturer's instructions for compatibility with our injectors if you are not using an ASNU fuel rail. Filtration A minimum filtration of 10 Microns is required for short term operation <3000 miles. For long term operation >3000 miles a filtration level of 5 M icrons is advised. The life of the in-line fuel filter is to be determined by the user in response to environmental conditions and fuel quality. Failure to adhere to these limits may result in a drop in injector flow / performance and damage to the injector itself. Service Life and Storage To maintain the performance and tight operating tolerances of the injector, it is advised to send your injectors to ASNU Service Centres to check their operation and be cleaned if necessary. We recommend replacing the O-rings during their service. Chemical cleaners may damage the injector and should not be used. Injectors that have been unused for some time such as with stored vehicles or spare parts should be checked before operation.
