I just bought an Sr20det redtop (with coilpacks idk if that makes a difference) hatchback, and it runs a little rich.

I went to change my plugs and noticed that cylinders 1 and 2 use red injectors and cylinders 3 and 4 were using a light purple injector.

once i pulled the spark plugs it was obvious that this was atleast part of the issue

Spark plug 1 and 2 had light carbon build up and cylinders 3 and 4 had excessive carbon build up that left everything black on the tip of the plugs

obviously i need to get a set of matching stock injectors but it almost looks like the red low flow injectors might run at a better fuel ratio, but my fear is that when it gets into boost it might run lean

I Know the purple are the stock 370cc
