I’m in the process of a 2.4 gt35r build, I plan on running just pump gas and I have been looking at upgrading my injectors to 1450 possible 1650.. for those out there running FIC 1650 I was do you have any issues running them, I have been told that injectors larger then 1450s tend to have issues.. Scaling, idle, ect ect.. any information would be helpful thanks

 

really nothing??

 

bump! i want to know too.

 

No. On gasoline you arent going to max the 1450s, especially 91 octane. For reference, 1000s and one 255 will support 600whp if octane isnt a consideration. A double pumper and 1050s (which flow like a 1200) should be more than enough.

 

I have them. They are a pain in the *** to scale. I still change things quite frequently. I'm running a full blown twin -10 feed -8 return with the 1650's and 37psi base fuel pressure. 30psi on a 37R and I was affraid I'd run out of fuel. First pass I logged 9.9:1 afrs. That is the low limit to my zeitronics so it was probably much richer. I'm stepping down to 1000's or 1200's. These things are way overkill man.
