I ordered rx7 550cc injectors, and the seller sent me something else...at 140cc.
So I found the site above, and noticed on another site they say the old bosch injector "atomizes on impact with the valve" whatever. Is this bad, and does the seimens function the same way? Its time to buy something.

i remember back from dsm days people were saying denso injectors were higher quality than RC and comparing the price i never gave rc a second look, maybe that's just old info or wrong i don't know
I'm pretty sure RC injectors have much better control at lower pw's and they most likely have better spray patterns than the denso ones most of us use. I don't mind my desnso's just have to get better control of them somehow.
the key to being cheap is knowing when, and by how much, you should cheap out.
I bought a garrett BB turbo and an HKS manifold, but I also used Megasquirt and 50$ DSM injectors, and aluminized steel exhaust and ic piping.
Low-impedance vs high-impedance is going to make more difference in controllability at idle than the brand.

RC injectors are built using the Bosch EV1 design. I'm sure they have a different quality control since they aren't producing on the same scale, but the injector itself is basically bosch.
I like bosch injectors, but I'm biased because I used to be a manufacturing engineer on the assembly line in Charleston.
