SR Fuel Injector Issue

[s.tamayo1991]

Hey guys so i just did a swap on my s14.. I put an s14 sr20. It came with tome 740cc injectors however one of them was bad. to no ones surprise i have a misfire. So i put an injector from my KA and it got a little better but still shitty. I need to buy another 740 injector tonight. Can i buy a Deatsch Werks injector from a 300zx same size same plug? or should i just get another Tomei injector for an SR? Im worried that the frequency or something internally in the injector may be different. I read some where that they open and close at different speeds. Anyone have experience with this? Much appreciated.

For me...same company and have them flow matched.

dont play with fuel.... duty cycle might be the same but the dynamics of each brand may vary go wid the tomei

Keep injector brand/type the same.

There's a reason not to mix and match the injector brands.
And a big NO NO for adding 1 DW injector. The latency and actual flow. The latency will be incorrect for the same size, and the actual flow will differ drastically. It's probably a better idea to have the faulty injector rebuilt along with the good ones. There used to be an addition driver device that could allow you to add the injector seperately from the ecu, you could use that as a temp fix, but the cost outways the first option.
