Working through the car I recently bought, I'm trying to work out what size Injectors it has. They look to be side feed and brownish in colour. I know some oem type JECs injectors are colour coded. Anyone know for sure? Really dont want to pull and test if I dont have to.

Version 3/4 had yellowtop injectors that flowed 440cc/480cc depending how many psi you tested them at. Are they the red N/A ej25d injectors that have been modded to flow more? No way of knowing unless you got them cleaned & tested.

Ok. I was told by someone they are 1100cc, but took it with a grain of salt. I suppose I'll get an idea when I finish tuning and see what pulsewidths I end up with.
From memory I set fuel pressure to 36psi at idle, measured just after the fuel filter right?
At least as a starting point.
