I'm pulleying down to a 2.9 and I was wondering what injectors I should get 42# or 60#s

 

42's will do isnt 2.9 stage 2?

 

Could be I'm not sure and I wasn't sure between the two

 

im running 42's with a 2.9. stage 2 is a little bit bigger 77.9mm i think so its more like 3 and some change

 

go with 60s so you have room to pulley down in the future

 

go with 60's

 

60's for sure. Dont wast your time with the 42's not much room to grow after that.

 

Go with 60s. I went with 42s on my 3.0 inch and am running 95% idc by 6500 rpm. My tuner didn't want to raise rev limmit to 7k, he told me injectors went static on one of the pulls he had it at 7k.

 

So 60s would be the best bet

 

my tuner said my idc's are good at a 3.1 pulley, im going down to a 2.9 in 2 weeks. with a retune and he is going to advise me if i should go with 60's or not. there is actually another thread somewhere going on right now about this with more info. alot of people are underestimating the 42's and their capacity. i told my boy though if im even close to going static im gonna grab 60's just to stay clear away from that because im running to 7k

 

If you have e85 in your area, skip both and get 79's or 80's.
