I don't want to play with the wiring, is there any plug+play upgraded injectors work with OBD0 PWO ECU??
Are DSM injectors any good?

thanks

 

Yes, DSM are fine, but as far as I know they are way to big (flow a lot more) than the 240cc injectors you have.
Accel, and RC sell injectors at fairly good prices.

How much HP are you putting down?
I say up to 200HP the stock ones (Clean and in good shape) are plenty.

 

I have RC's 270cc/min injectors, they are plenty for my application. If you keep your car NA and don't go ITB's then there is no need for the DSM 440cc injectors, you would also need a fuel controller for such a large injector. You can have RC blueprint your stock 240's for more flow, but if you want to improove the spray pattern, then get some of their custom injectors. I have a tri-spray pattern injector... which is suppose to give a better air/fuel atomization. The only reason why you would need larger injectors is if you have changed the displacement of your engine, design of your Intake manifold/head/cams, ect.

 

My car is NA setup, B16A, CTR piston, JUN III, Mugen HQ, DC header, cam gear, Mugen chip etc..
I found its running too lean, been adjusted the FPR then get code 43 in highway.
may be I'll need bigger injectors.

How much should I expect to pay for set of injectors?

thanks for the input

 

Did you get a Mugen chip that dissables the secondary O2 sensor? If so that eliminates the common problem of connecting both inputs into one O2 sensor. What are your "tools" for measuring the air/fuel ratio? Are the injectors that you have now maxing the duty cycle? How high fuel pressure are you going to get the 43 MIL? To get brand new injectors you are looking at $70-80. Where did you get your "Mugen" chip from? You shouldn't be running lean with it.
