42# injectors for an '04



One more week of work and I'm retired. I'll have plenty of time to work on the GP. First I need to get all the part together.
 
Yeah that was my next question...most likely they are short body also so l32 folk would have to fun spacers

They might work with my intake swap I had to run spacers with the stock LS4 injectors with these I no longer had too.
 
Stock ls4 inj 1.52 oring to oring 1.97in overall
Ls4/spacer 2.12 oring to oring 2.65 in overall
Flex fuel 50# 1.88 oring to oring 2.13 in overall length
 
Just measured my stock l32 injectors and they measure 2.875 end to end so those 50lb injectors should work great with spacers...I currently am running cobra injectors which are perfect length and are ev6 but they flow a little bit less
 


I'm going to start this soon. I was hoping to hear from Will so I could get a tune at the same time.
 
I was told today that I don't need bigger injectors if I don't go below a 3.2 pulley. Is that a fact?
 


I think below a 3.4 is when your start to look for bigger injectors. Best to upgrade now and have will tune for them all in one shot.
 
I was told originally that I could go to a 3.2 with my setup and injectors and tune. Today I was told I could go as low as 3.2 without getting injectors. The consensus seems to be though that I need them for the 3.2. I wanted will overkill to do my tune, etc but I haven't been able to reach him again.
 
I cracked 100% idc with a cam and 3.5 pulley so don't think you will make it to a 3.2
