Do I need bigger injectors yet?????? heres my combo.2002 ls1,stock 28# injectors, mild ported 241s, 85 mm typhoon intake,billet fuel rails,85 mm tb, 85 mm mass air from vett. ms4 cam,tsp valve train,harland sharp roller rockers,fidanza aluminum flywheel,spec 3,arp head studs,100 shot nos,m6 car, long tubes,4.10 gears.any help would be great. thanks
I don't think 30# will be enough even without the nitrous, even 36# are going to be over 85% duty cycle, I'd say just get 42s from FIC.
EDIT: didn't catch it was a wet kit, 36#s should be fine, only around $225 flow matched from FIC.

42's at 3 bar will be plenty, even for a much bigger shot.
around 80% i believe.... ive got a set of 36# injectors @ 3 bar. so they are 42# @ 4 bar? think they are enough? not doing any engine mods for awhile,building 8.8 and doing suspension mods for now.
Right now you're guessing. Unless you monitor it w/appropriate software, you won't know... AND if you put them in, you'll need a tune anyway, so plugging them in won't do anything good for you unless you have the equipment ready to go to KNOW how they're working. Plug them in and ignore proper tuning could result in flooding the engine and costing you alot more than a tune runs.
i know it needs a tune. plan on it. im a caterpillar tech,im not retarded. just trying to figure what size.its been on a dyno, they were close to maxed out. trying to see if someone with similar combo could suggest what injector to get.
The 36's will net you around 41# and should be more than sufficient. Never said anything about your intelligence, just pointing out all the information is needed for appropriate answers. Saw you're not too far (about 3 hours) from me. You have a wideband bung welded into your exhaust by chance? Using all 4 of your O2 sensors?
