sr20det bogging/not starting/burning up spark plugs please help

[sergeantb23]

Alright, so I am a new sr20det owner and am having some serious issues.

I have been bogging down at about 3000-3500 rpm. When I shortened the gap on the spark plugs it ran fine up to 6500. Then it started bogging again. Changed the spark plugs and ran fine, then started bogging again, now at 2500 rpm. Finally with new plugs (old ones were filthy after 10 minutes of running) again, it started bogging at 1500. Now it won't even start.

I bought new spark plugs. I changed out the coils. I tried another distributer. Nothing seems to work.

Can someone help?

It has 550 fuel injectors, thought that may be important

Did you check your mixture...sounds like your running too rich! It would explain your spark plugs fouling up as you describe and bogging...If you havent played with your fuel map its probably a faulty sensor.

you changed the distributor? sr20s dont have distributors? how much boost are you running? is the only thing changed on your setup is injectors? if so you most likely need a tune.
