injectors

[connors14]

hello im a new member i bought a kouki s14 with an sr20det from a friend of mine a few months ago sadly the turbo blew 2 months ago from poor quality boost controller. Anyway I'm upgrading my set up with an oem s15 turbo and i want to know what size injectors to use. Ill be aiming for around 300, also i would like to know if anyone has ones for sale i appreciate your help thanks.

hks 550cc's

As a rule of thumb, for 4 cylinders I use the size of the injector x (2/3).So 550's should be good for 360hp crank.

thanks all very much for your help that was just the one thing i wasnt sure about wether to use 550 or 740

I would go with the 740's, it seems more often than not people are selling their 550's to go bigger. Just bite the bullet now and have room to grow with fuel.
