97 gsr built engine
running a hondata 2b
want to boost 1 bar (14 psi)
what size rc injectors should i get
and what else do i need to run the correct fuel setup?

 

Walbro 255lph, B18Bturbo is having a group buy, pick one up if you want. Maybe 550cc injectors with a resistor box. That's all I can think of, anyone else?

 

thanx for the reply,
ya i was thinking 550cc injectors also.
for the pump is that an in-tank or in-line?
where can i get a resistor box? and how much?
anyone else......

 

your right 550cc or 55lb injectors should work just right..

 

Do you really need the resistor box if you're running a Hondata?

 

I would think so because Hondata still uses the stock drivers.

 

Our stock motor B18C 'teg boosting around 1 bar at stock fuel pressure and 255lph HP walbro never got above 78% duty cycle on DSM 450cc's.......so if you're ever planning more than 14lbs (which I assume you are on a built motor) you'll probably want 530's or more.....
FYI, the JDM 4G63's came with like 530cc's, so if you can find a DSMer who bought one of those motors you can probably get 530's for like 70 bux

Hondata and AEM both require a resistor box for low impedance injectors. I just did a hondata install with 720's and the car ran perfectly. If you are going to do the whole resitor box thing I would save yourself some hassle later and go with 720's.

 

thanx guys,
im gonna be running 14 psi max (track days or big street races) 5% of the time.
probley around 8-10 psi on the street. 95% of the time.
so do u think the 450cc's 550cc's or 720cc's??
any other comments / suggestions??

turbo and most parts are from a drag gen 3 kit

turbo size will play a large part on the fuel requirements.

 

yeap. I'd recommend 550's if you are sure 1 bar is all you are going to run. If not sure, go up to 660s or 760's. They both work fine with Hondata.

 

thanks again for all the replys
im gonna go with the 550cc's with the walbro pump
am i gonna need a fuel pressure regulator for tuneing?
also where can i get the resister box from?

 

you won't need a regulator. I've made nearly 450hp without touching it.

You can get the resistor box from
90-91 Integras
88-91 CRX Si and HF
92-96 Prelude
90-97 Accord
88-89 Integra

and probably a few more I'm missing.
