Difference in injectors Nova GSI...

[RSTChris]

As title

Both engines are from J plate cars, one has brown injectors, the other has cream

Any difference? the cream engined one seams faster imho

[Adam]

You quite often get two identical engines, with one being quicker than the other.
Just depends how they've worn etc.

[Mike]

You'll find they'll be feck all difference TBH, maybe one colour has an adjusted spray pattern, or the injectors were manufacturd by a different company etc

[RSTChris]

I get ya, thanks

[burgo]

are you peeps 100% sure there the same?? just i remember reading that some gsi engines run 2.5bar fuel pressure and others run 3 bar. so may the injectors be different due to this??

I've broken & had many E16SE motors in my time. I've never come across brown injectors on one.

I reckon someone has slapped them on in order to 'tune something'.

Quite possibly.

Maybe with the Siemens/Bosch management change?

[craig green]

But my argument stands here. I've had about 4 engines with Bosch ECU & about 3 with the Siemens ECU. All had creams.

[Adam]

Your probably right then Craig.
Someones probably fitted them as a "mod"

[craig green]

''mod'' indeed. I've never actually encountered a C16SE if thats where they are from.

[Adam]

That could be the answer.
C16 used a completely different management system, so probably had different injectors.

[craig green]

And a higher rail pressure no doubt.

[RSTChris]

No idea me lads, i just noticed mine had browns ones....

My so called standard GSI engined nova certainly feels quicker than it should be :S
