with the 2.87 (10.5-12 psi) i would get at least 600cc injectors
good luck with the build

 

anything after 500cc on the SS box (that comes with a vortech kit) will have issues. Some have gotten 550's to work but i do'nt think well.

OP says he has a tuner kit so this shouldn't be an issue if he chooses a good engine management.

 

Just got my kit today with 440 injectors and a 3.12 pulley... OP GL with your build!!!!!

Yes patents is something you learn very quickly when going FI everything takes longer then you think and cost more then you think. But I have heard it's worth it I hope to find out for my self some day. Remember if it's worth having it's worth waiting on. Good luck. Kirk
