The stock fuel injectors on my V6, are 22 lbs. My goal is to run 5 PSI, what engine internals would I need to change to achieve that. I'm thinking, PCM reprogrammed, and 30 lb injectors. Does that sound right? Should I be doing more? Thanks

do you have a turbocharger on there now or are you adding one?? cause if your askign the question about adding one and looking to see if you need to swap any engine internals. As a good way to answer that might be to look up the engine specs on a car that has stock turbochargers then compare it to the same engine on a car that did not have the stock turbochargers and see if the manufacture (GM or whatever) cahnged any internals, I'd geuss heads diffrenrent... pretty sure GM did some stuff like that on the 3.8 in the late 90's but can't say the details as I never got into it... anyways maybee it's best to put this in the the forced induction room??? but I'm just a user not a moderator

 

i think the stock L67 Injs are 32# on the series II 3800 s/c, might be a little small IMO...
