ASNU 1050CC Fuel injectors for Vauxhall Z20 Engine
 
 
 
We use ASNU's range of injectors on most of our builds now, where ever we have the choice to. We have found the data that ASNU provide for calibration, and their dedication to accurately matching them up into "matched sets", to make tuning much more straightforward.
 
ASNU name their injectors based on their flow rate at 3 bar of fuel pressure and 85% duty cycle. Remember this if you are comparing them with other brands, as usually people will give the rating for their injectors at 100% duty, or their total flow rate. If you wish to compare properly then use the graphs provided for the data you need.
 
The use of precision cut atomiser plates on the ASNU's also makes them much more appealing over the "hose pipe" style injectors that are simply a bare valve. They allow for the fuel to be properly broken up into small droplets before injestion in to the engine. Small droplets of fuel evaporate much quicker than large ones, meaning more of the fuel will be vaporised by the time it is in the cylinder. It is only the vaporised fuel which will burn in an engine. Any liquid fuel that cannot be vaporised will be left over, and will simply show up as black smoke out of the exhaust.
 
We run the 1050's on all the high spec 2.0 4 cylinder Vauxhall Turbo engines we build now, with the standard Bosch ECU, and to great effect! Idle, part throttle and cruise are all nice and smooth with them, showing good low speed, low pulsewidth, atomisation. The characterisation data that ASNU provide is spot on, and makes tuning them easy.
 
This is for a set to fit the Vauxhall Z20 engine. They come with a set of adapters to allow them to be fitted directly into the original fuel rail using the original electrical connectors, the only modification is to fit the supplied washers under the fuel rail, due to a slightly longer overall length.
 
These injectors will see you right upto and a bit beyond 650hp, without raising the fuel pressure.
