going to have a built motor in about 2 weeks and was wondering if my stock injectors will be ok for the break in tune??? i do plan on getting either 50 or 60 lb injectors but cant afford it this week. and no i dont plan on racing or anything anytime soon

 

They're fine for break in. Just stay out of heavy boost. As long as you don't exceed your fuel requirement they work as well as any.

what are the limits for the 42# injectors?

 

around 500 ponies

 

With stock fuel pressure mine were going static at 4700 rpm with 15#'s of KB boost. This was at 462hp. I just got 60's cause they were on sale for $399 and I have heard they have a very good spray pattern at low rpm also.

 

thanks Jody, thats the answer i was looking for

 

I have a set of 50's on the way for when i get my built motor in. I planned on running them on break in unless i was told to go with the 42's instead

 

put the 50's in when you do the motor
i am not doing this just because i do not have the funds to buy the injectors right away, i am just waiting for the next paycheck to come in then they are going under the hood
money tightened up for me doing the motor that is the only reason i am waiting

 

I know what u mean i wont be able to add pumps or a bigger mass air untill after i get the motor in. I just got a good deal on these so i didnt pass it up

 

Lots of discussion on injectors which injectors have the best spray pattern and which one should be used with a built motor.
Some say use the 60# while others say 50# and 55# probley doesn't make much difference as long as engine has the right tune for the injector????? thanks
