THANKS IN ADVANCE

 

270 should be fine...

 

i got a good deal on a set of 440, but they would work fine with hondata s300

 

Until you get a tunable computer, I wouldn't bother with changing the injectors. Is the current ECU tuned for stock injectors?

 

No not for stock. I told phearable that I was using RC310, I'm still running my stock injectors.

 

how about OBD2 H22A injectors. Pretty cheap and 290cc. Keep it all HONDA!!

A good suggestion, and as Reid alluded to, I would definitely upgrade to a tunable ECU setup.

.....just get the 310's. although, for myself i'd go with 550's.

 

If you ever build your motor you could max out those 310cc injectors, so I'd go bigger, at least 370-440cc injectors.

 

Im running RC440's
My tuner loves them, it gives him more flexability.

 

Thank for all the replies everyone , but isn't the jdmITR injectors between 220-270?

 

what is the down side of running too big injectors? Bad gas mileage? would it put too much stress on the fuel pump?

 

440cc injectors wouldn't be too big at all, tune it well and you will get great gas mileage, there will be no extra stress on the fuel pump.

 

I opted for the 310's on a stock motor w/ bolt-ons. Will see how well they work next week after the tune

 

To the OP, I would just get the 310's unless you plan on get something to tune the car with. If phearable set it up for 310's then that's what I'd use. However, if you do plan on tuning then something bigger wouldn't hurt you.

For my own personal inquisition, would 370's be suitable on a stock block/head? I'm thinking a good header/exhaust, intake, and good fuel management could reach something close to 190 at the wheels. Would the 370's suffice or be completely overkill? Not trying to hijack, just thought I'd keep my questions of the same topic in this topic.

 

Let me know how things work out

 

As far as fuel pump, Im running a Holley 195LPH. Will RC310 or anything bigger be suitable for that intank pump?

 

Yeah your fine.

 

Lightning motorsports has a really good deal on the RC injectors. Should I stick with the RC310? Im in the process of making an order. Any last suggestions, I just don't want to regret?

 

just get the largest saturated injectors available.

550cc or 750cc

 

yeah. i got 310 cc on mine.. i should have went bigger.
and i just built my n/a motor.. m22xx + ctr pistons + 4.9 FD. hmm

 

RC310 injectors should be fine up to around 220whp.

That would be my pick for your setup

Btw, you might want to consider getting your car tuned once you go with a larger injector, or you may want to atleast order a basemap eprom chip.

 

well, i dont want to recomend AFperformance if you want the injectors fast. i has been over 2 months since i payed for them but i have not recived them

 

get the 310's it gives you alot more playing room if you ever get bigger cams and build up the motor more....I am getting ready to sell my rc 310s off my R in about 2 weeks ifyou wanna hold out. It could save you some money.

 

thanks for the info
