ASNU R35 GT-R 12 Injector Conversion Manifold

Part No: ASNU92/R35GTR C/KIT

ASNU have 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 optimised 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 fibreglass and carbon bonnets so fitment issues even on non standard panels are not a problem.
