hey, i have a 98 GSR with 18g greddy turbo kit

my question is, when should i look to upgrade my injectors? i only plan on making 250-260 whp. will that power max out my injectors?

im asking this because my power peaks at around 5500-6000 rpm. i know my cat and 2.25in exhaust has some effect on that but i was also wondering if i would need bigger injectors, if so, which ones?

thanks - kinda of a n00b question sry

 

310cc is good up to about 200whp, get some 550cc and you'll be set

 

well im making that on a stock kit on stock settings - why would greddy have included these injectors if they would nearly be maxed out from the get go?

anyone else?

also tuning with hondata s200b

 

bump

 

Your going to need bigger injector anyway, the 310cc will not be able to get you to 250whp

 

well which ones should i get? and where?

 

550cc is good enough, wiredspeedlad is a good place to buy from whose also FI sponsor

 

since i have the greddy injectors now, should i just go with with greddy 550cc injectors?

i see that they have other fittings and stuff, would i need anything like that? or should the 310cc's just swap out for the 550cc's?

 

550s at least so you have room for improvement

The 550cc (RC) from wiredspeedlab will plug right in to the clip for your 310cc now

 

StolenTeg - i PMed you for some info

what is the difference between saturated and Peak & Hold injectors? which one for me?

 

so i would want the saturated ones?

 

the RC (550cc) injectors will plug into my clip for my Greddy (310cc) injectors?

Also contact Arturbo on here for precision injectors. Just get some saturated 550 injectors....RCs or Precisions and you will be set.

 

ok - well wiredspeedlab is running a H-T special for RC injectors for 280 shipped. so i think ill jump on that- are precisions any better?

 

Does going from 310cc injectors to 550cc require a change in the fuel pump????

will i need to upgrade from a stock fuel pump? if so, which one?

 

hEY I IM'ED YOU

 

IF YOU GET THE 550'S INJECTORS YOU SHOULD BUY A 255 WALBRO FUEL PUMP
I GOT THE INJECTORS BUT NEED THE FUEL PUMP BUT ILL SELL YOU THE INJECTORS.

 

Walbro 255lph or 255lph HP??

 

also if there is anything else i would need to do this right let me know... fuel rail..etc...

my set up:
18G greddy kit @7-8psi & intercooled -SBC-ID
3" thermal w/ test pipe
Hondata s200b w/ p28 ecu
stock internals and basically everything else

 

No, you don't need to upgrade your fuel pump

Because Greddy never intended your car to make very much power because then you'd blow it up and they'd have a lawsuit on their hands.

 

ok ive got one vote for change in stock fuel pump and one for no

btw - i will only run 550ccs and max of 8-9 psi (but most likely just 7psi)

so if you suggest upgrading the pump for room to grow, i will not need that extra room for bigger injectors, this is my DD and this is all i am going to do basically. just looking for around 250-260 whp
