Can I run 630 cc inj with a turbonetics kit and I'm gonna install the aem fic to tune it to the 630s . And it's water meth inj . Whets the pros and cons . Or should I stick to looking for 550s .

 

630's will work fine, as long as the fuel map is calibrated for 630's

 

yeah id def go w 630s. u can always tune em down

 

i'm running ptunings 630s. as long as you're tuned with the 630's then you will have no problem. also leaves room for the future if you want more power.

 

there is still the myth out there that you can run too large of an injector?

 

the only problem you will run in to with injectors ever is if you go above 700cc w/ a piggy back your idle will be annoying. atleast thats the word of mouth around here. i'm using 700's and my car idles like stock.

 

untrue

 

orly? i was thinking about buying 1300's but was told it will idle like poo on a piggy back.

 

I run 1000s at a base pressure of 80PSI which plants them at around 1200cc my car always starts and idles fine.

If you dont have an experienced tuner dont buy them.

 

i've got shaun @ church's automotive here even though his dyno reads rediculously high he is still a bomb tuner. the thing is with yours though 1000 cc's act like 1000cc's outside of boost. i ment to say in my original post that over 1000 cc's dont idle properly.

 

no my base fuel pressure is 80. it goes over 100 in boost

 

ooooooh.

 

i think in normal cases when base pressure would be anywhere in the 45-50 range, the 1000+ injectors would idle like poo as syldrin was saying.

 

i'm only saying with a piggy back it will. because you gotta remember our stock computer uses a % of fuel our injectors can deliver so say at idle the car is saying throw 20% fuel from the 340cc (or w/e the stock ones are) injectors. you change those to 1300 it's going to use the same values for the 1300's
