I got a 95 gt and im installing a cam(but dont know what cam to use), heads, and intake my question is how do i figure out what # injectors to use to get the car to run right

minnow81469

Im going with 42# inj, calibrated maf, and a larger fuel pump how do i get it so im not running so rich is the real question sorry that i confused everyone

you'd better have on heck of a stroker or supercharger on that 95 to need 42 lbers

i dont have either yet but planning a sc here soon my buddy sold them to me dirt cheap so i want to use them if i can

better off swapping back to your stock injectors and maf until you do the S/C install

Most cams require 24# injectors others id leave it and hes going to sell me it for way cheap

wowvfast

no, most cams don't require 24's...these cars are pickey with larger cams and that computer...small is better

well i called comp cams and they suggested 24#'s for the xtreme energy cam and im not worried bout the comp because im getting tuned after the install

if you have a complete set up that requires more fuel delivery than what stock can effectively deliver then yes = time for inj upgrade, like when doing an aftermarket h/c/i that is large enough, cause alot of the typical h/c/i's can use the stock 19's just fine...in fact when all adjustment are made properly, I've witnessed 300 to 320 rwhp on stock 19's but at that range the duty cycle on the injector is near 90 percent and when climate change occurs..ie cooler/more dense air....then you might run into an issue where it'll start to lean out/max injector out.
