550's will be fin for your set up. I'd go with 650 or 660's though.
I'd also get an adjustable fuel pressure regulator.

ok thanx for the help.

What he said, except I would only consider ball style injectors. They spray a much better mist of gasoline vs the petel or whatever style. I think there rated like 10cc's less but they make up for it with better combustion.

 

[norice4me]

thanx do you know ware i can get them at a cheaper price. well any ware would be fine thanx.

 

[dsmturboawd]

550's are more than fine.

A little ways down. 550's are $57 each.

 

[norice4me]

thanx the 550's i understand but what i do some more mods like a viger turbo and stuff how much more mod will i need for likr 680's or somthin so what i am asking her is will i max out the 550's if i upgrade soon.

 

[ItsStockOfficer]

660's, and what do largfer injectors have to do with a AFPR?

 

[norice4me]

what are you saying.

 

[ItsStockOfficer]

AFPR's are related to fuel pump size, not injector size. i run 720's on the stock FPR.

 

[norice4me]

ok so if i get a fpr i would be fine with the 550's or should i just got with the 660's

 

[ItsStockOfficer]

...get 660's....


And since you have a 255, a AFPR is always good, on any injectors....

 

[norice4me]

ok thanx for the help i was going to get a fpr and then the place i ordered from to way to long and woulent even take my money so i dident get it so maby you no of a place ware i can get one with some sort of fast shipping. thanx

If i were to get an FP3052 or FP3065, what kind of support mods would be sufficient? This is was i was thinking:

DSMlink v.2 or Greddy Emanage or datalogger
255HP Fuel Pump
AFPR
SAFC 2
680cc injectors??

what else is good?

 

[crankbender]

Fuel pressure has everything to do with what injector size you choose. The flow numbers given with injectors are at a base differential in pressure from the fuel rail to the intake. If you increase that pressure you increase the flow from the injector without going to bigger injectors. Think of blowing through a straw. If you blow softly little air flows if you blow like a girl on prom night then you get alot of stuff comming out (pun intended).

That said increasing your fuel rail pressure differential may also result in a much better spray pattern and better atomization.

do yourself a favor and dont get a 3065. that ####ers bigger than a red.

Sorry to get off subject here, but im also looking for a good deal on some quality injectors (ball and seat/disk style), and nine5raptor recommended the ones from dejon tool ($228 total for 4), does anyone have any experience or reviews on these?

 

[norice4me]

That was just the cheapest I had seen for 550's.

 

[norice4me]

[eclipse17psi]

[TTalon]

kinda off topic but how much can the 450CC handle as in psi? 16?

 

[nine5raptor]

psi is irrelevant. You need to look at flow and a/f ratio/
