1st timer: bigger injectors in a nissan

[Hugh Keir]

Mark,

I am surpised that your car has 260cc injectors fitted to a 3.0 litre twin
turbo.

The Nissan Skyline is a 2.6 twin turbo and uses 444cc injectors, and uses a
smaller 70mm airfolw meter than the ZX 80mm.

Flow rate is always a function of pressure and I beleive it is customary for
Nissan to quote the flow rate at 2.5 kg/cm? sq ( approx 2.5 bar ) although
the Skyline idle pressure is around 45psi.

Apexi and Link are possible manufacturers of plug in ECU's that are easy to
tune, although may not have the adustabilty of a wire in ECU.

Hugh
