What is the difference from RC and Precision injectors as far as spary patterns and quality?

 

Precision injectors are really bosch injectors.

I have yet to compare the rc & precision injector design/spray pattern.

I have used both precision & rc injectors without any issues on hundreds of cars.

 

Precision injectors for the most part use a "ball and seat" nozzle style for their Honda style injectors. Looking at a couple crappy RC Engineering injector pictures online it looks like they use a "disc" nozzle style. Precision injectors are manufactured by Rochester/Lucas. Precision simply flow test, calibrate, clean and package the closest matching injectors to one another. Like Mtber said. You will have no problem with either

 

Thanks for the info. Another thing is that my factory injectors are high impedance right? If I go with anything higher than 525cc with precision I would have to get a resistor box. But I see RC has high impedance injectors that are higher cc. And with both companies I would have to get clips regardless right? Thanks again.

 

Yes, your injectors are high impedance.
Yes, you will need clips regardless.
Rc makes up to a 750cc saturated injector.
Personally I like using a low impedance injector for anything over 650cc.

 

Basically the RCs shoot a stream while the Precisions shoot a mist.

It is easier to tune Precision style injectors due to there spray pattern. Also idle quality will be better with a low impedance injector.

A resistor box is easy to install. Please don't just cut and twist the wires. I made mine so that I can unplug it if needed, plug in the dummy plug and install stock injectors.
