first of all...i am kinda a newbie but thanks to honda tech ive learned a alot....i have a few questions though because i am currently putting together a turbo setup for my 94 gsr....im kinda knowledgeable about everything else execpt for fuel management on a turbo setup...my power goals are just around 250whp for my daily driver....i already have my ecu chipped for uberdata and knows a friend who had a wideband....i have three rc 370cc injectors given to me from a friend because he lost the fourth one...my question is will 370s be enough to support the kind of power im looking for?....if so imma order a fourth injector.... or can stock injectors do the job?...or should i upgrade to bigger injectors than 370s?...and also should i add a wal255 fp?....kinda confused on how this fuel stuff works...just tell me what i should do...want to run around 7lbs of boost on a sc34 turbo as of now...thanks

 

I'm not a fuel injection specialist, but my advice would be to move up to 450cc injectors. The 390's may well take care of what you need, but if there's one thing about turbo owners, it's that they will eventually want to "just crank two more pounds out of it". lol. When this time comes for you, you'll know that you are ok because you DID make the 390 to 450 swich.
The walbro pump isn't something that's absolutely neccessary. You stock pump will work, but it will be working harder than normal. If you want the piece of mind, I would upgrade, but if you use the stock pump it should be good.

Don't use stock injectors

 

yep, I agree with him, move up to something a little bigger, so you aren't as close to maxing out the injectors.

 

I'd go with at least DSM 450's (should be able to find a set for around $50) or if your looking to upgrade in the future RC 550's or possibly bigger. The walbro will be plenty of pump for you.

 

im kinda low on budget right now to get a whole new set of rc injectors...would it be really bad just running the rc370s and just uberdata tuned?...around what % would they be running if i was only boosting 7lbs?

 

You will probably be running >= 80% duty cycle on 370ccs. I'd use something larger.

Yes, a walbro 255HP is fine.

For $50 DSM 450's would be cheap insurance.
