Thread: 650cc

im getting ready to purchase some 650cc injectors, and woiuld just like to ask you folks if you know anywhere that sells it less than 199 shipped? and plus does any one of you guys run thesse?

alright i bought it from agpturbo.com. like you say the deal was good, every where else was $309+.... by the way what do you guys think i should boost up too when i drop these 650s in?

current mods:
o2dump from there on 3" back
255 wb fuel pump
s-afc
big16g
greddy pipings with types bov
k&n fipk
ngk iridiums 2 colder than stock
manecore wires
front mount 24x12x3

youll need an AFPR. too. youll have to lean the car out so much with the afc that your timing will be be too advanced and youll knock on pump.

so i cant boost 18 to 20 psi, with out a afpr?

you will need a afpr no matter what.

oh yea i know that. but for the for now, until i get a afpr.

An afpr makes it easier to tune and helps with a rich idle. Its not absolutley nessecary. There are cars making big numbers with a safc and no afpr. As long as you can tune the knock out your good to go with whatever boost you can tune it to without knock.

Yep /\ He's right. 19-20psi SHOULD be ok, but you'll find out once you start tuning. If you're untuned and not logging anything, I wouldn't boost anything over 17psi.
