i have a turbo gsr motor in a civic. its a t3/t4 turbo running 5.5psi of boost. i need injectors because now im running stock injectors on a fmu and i figure with the injectors and fmu i can turn the wick up a little.. id like to set a target of 7-9psi of boost if thats not to much... what size injector should i use ,i was thinking 360cc around there and also what boost should i be running on a stock jdm gsr motor.. compression is 10.5or 10.6 to 1 my mods are listed below.... thanks

i have a very similar setup. you might wanna invest in an actual ems if your considering turning the boost up. I run 9psi with hondata with a conservative tune and see 290whp. as far as injectors go u can really go as big as you want. the 360's, 440's, and 550's all cost relatively the same. I went with 550's for room to expand later. or the cheaper way would be to get some 450 dsm's.

 

hows this setup walbro 255 pump (already in the car) dsm injectors,vafc,and an adjustable fuel regulator... can you use the adjustable fuel regulator with the vafc... is that a good setup.. i need to know need to start buying very soon ive gone to long on stock injectors
