Running 2.0 injectors on my stock 1.8, new fuel injection fires all 4 at one time (batch), I have a feeling new injectors are too much....anyone lower their fuel pressure to compensate for large injectors??

I'm wondering how low can I go yet still retain a nice reliable pattern?????

I know you can lower them a little but, I seem to remmember that it is not a lot. If I remember correctly, because of the large pintel (sp) the spray pattern will suffer.

Here's a link to a pretty good paper on injectors available. I've played with a Borg Warner aftermarket 0 280 150 151 that flows 240 cc's per minute. They gave me a pulsewidth of 2.0 ms at idle. If you d decide to use any Borg Warner injectors, put hose clamps over the hose on the barbs. It appears they are swedged on bot I had a hose come off.
