What size injectors?

[OneSickTSi]

I've got a Big 16g now, and my FMIC isn't being properly used and I'm thinking about upgrading to a 20g turbo, an APEX'i S-AFC, and pushing 18 PSI, I was just wondering what size of injector should I go for, I was thinking about the RC 550 cc injectors, but also was looking at some 720 cc injectors.

550's wont be enough, and you should already have them with your current setup, 660's or 720's would be more appropriate.

go with 660's 720's are very hard to lean out even with a 20g.

Get the Injector clinic 650cc injectors. I have them on my car with a 20G and they are plenty. www.diamondstarmotorsport.com and www.extremeturbo.com sell them, among other places.
