Injector Suggestions

[boscov6]

Hello all,

I have been reading a lot on this forum and have learned so much . The knowledge base here is amazing. I am currently building a hybrid 3400/3500 and plan on boosting it using the 3400 fuel rail on a 3500 complete top. The one item still left to obtain is the injectors. The 22 #ers that are stock obviously are not enough and with 8-12 ponds of boost in mind, stock pump, adjustable regulator, What would be a good rating on injectors. I think the 28 # TrailBlazer Multecs are a bit too small and the Bosh 42-46 #ers a bit too much?. I understand the Cobalt SS runs a # 32.
Any information or opinions would be great. Thank you

What are you using to tune the ECU with? if you run larger injectors you can recalibrate any size injector you want, slightly larger is better then slightly smaller. Assuming you have access to a tuner....
Walbro 255LPH pump, Stock FPR, 42.5# injectors (zzp or any other 3800 site offeres them). (this is what i run on mine)

this is kinda random and i apologize but i was looking at your sig monte and im confused. how the heck do you have a 3400 (im assuming thats what it is) z34 w/ a turbo even and it only rad a 14.38? that just seems wrong to me. i woulda guessed at least a mid-high 13 pass. ive heard of other grand ams w/ less power running faster. im just really confused..maybe im missing something..lol
