I use Nissan's SR20 Injector...with SARD Regulator
and Toyota's 2JZ Fuel Pump with my build!!

I hope the info does help you a bit..

 

What size are the sr20 injector..?

Thanks 4 the help
P.s good luck on your build what whp are you looking at?

 

I think it's 310cc. [99% positive] as SR-20 is also 2 Ltr. engine,
And I got it dirt cheap [which I also think you could do the same by getting them used from any junk yard] The thing is you might need to do a slightly modification on the plugs.

Other alternatives would be Acura RDX's injector, it's like 45 bucks a pop? It's 310cc and I've read many times over that it fits and work. Prelude's Injector would also do the trick.

However my builder and tuner told me I'd need a fuel regulator and better fuel pump in order to ensure smooth as silk fuel flows. A lot would tell you it's necessary but in the high rpm situation one would wanna make sure there's enough fuel to go around. Again, it's just me.

I'm expecting my build to be at least 210++ whp on 95 pump gas. It should be this weekend that I complete my run-in and hopefully the tuner would be free for real-time street tuning first.

 

well i already have a set of RC 310cc injectors, so i guess ill just use those. i also have a waldro fuel pump so i guess im all good 2 go.

thanks again for the help.

does anybody else have the same setup and use 310cc injectors?

Are you sure they are SR20 coz to my knowledge all the SR20 injectors are side feed style with the exception of the GTiR pusar which runs 444cc top feeds same as the RB26DETT

I apologize for my mistake, the injectors were taken from RB20DETT and not the SR20, you were correct!!! My bad!!

I guess it wouldn't hurt if you would add additional fuel regulator just like what I did. There you have walbro pump and then bigger injectors, honda's regulator can only handle certain pressure I suppose you can do the math for the rest. I'm sure everybody else would say it's a waste of money but then again, it's just my stupid humble opinion, of course, I could be wrong

Oh I'm sorry I do have a fuel reg, sx fuel reg... . What type of camgears u running?

 

My cam gears are DIY made from Honda's Factory, it did cost me about US$50 to mod the pair and they work just like any other $500! My cams are B16B, the details are in my thread!
