325i Fuel Injectors

[doolie]

I'm looking to get some more power out of my 325i without having to fit a trick cam. Can anyone tell me if fitting uprated fuel injectors will help and where I could get them from (and would I need an uprated fuel pump to), or any other little tweaks that can be done for track days/sprints?

I'm new to the E30, but already hooked on 'em.

Dont think that injectors will make a diff tbh and im sure ive read someone saying the same on here

Maybe go for a chip, zorst and filter and set up on a rr

[dazleeds]

bigger injectors will just flood ya engine and cause loads of grief longterm

stick with standard and get onto ant for a chip fella

and if funds allow get a big bore tb

If you went with bigger injectors you would need mega squirt to contol the flow or there wiull be to much fuel going in and bore wash.

think there 14.?lbs on stock -motronic wont idle with 19s and is pig rich running with them.bigger injectors have a place but not with stock management.

some say can be done by bigger afm/tweaked spring with adjusted fuel pressure....

You'd be far better off fitting a Schrick cam, they're not that much if you talk to the right people! Any injector upgrade would only be any good if you are getting more air in to match and that means cams and remapping, you'd also need an adjustable fuel regulator,

the other thing to consider is having your current injectors sonic cleaned. I had it done to one of the race cars and it's quite suprising how much of a difference even that can make. If your injectors have done high mileage and never been cleaned, get it done. Then investigate the cams like Dom says.

Yeah good point Paul, we just had ours sonically cleaned, 2 of them were blocked and all 6 were out of balance, should give a few ponies back!

Get a Mark DaSilva chip, best chip ever made!!!
