Does anyone know what the different style of injectors mean (http://www.allmotorhonda.com/techpages/injector.htm) peak + hold vs. saturated. What about pico vs bosch, whats the difference there? What injectors would you recommend for an LsVtec with PR3 ecu?

 

All you need to do is make sure everything matches your ECU. If you are running a PR3 then you need to use the peak and hold injectors with a resistor box.

 

yeah, but for curiousity's sake, what is the difference. Nobody knows (Honda tech's, Honda's Tech Line, Fuel Injection Shops), or has even heard of "these different style" of injectors.

 

peak and hold injectors are a differential style than saturated. One runs high voltage/low current, the other high current/low voltage. One has a better response time, but dumps less fuel. I can't remember which is which off the top of my head though, sorry. The difference is all internal to the solenoids or the inductors inside the injector that move the plate that lets fuel into the nozzle that squirts into your engine. Complicated? not at all.
As for the brands, some are considered more reliable than others... or closer to their claimed capacities... or give better response... or less likely to clog...etc etc.

 

finally, my anwser. I'd bet that saturated are considered all around better, as all Honda's seem to be comming out with them, yet I doubt peak + hold will seriously hurt performance (B16A is peak and hold + 100 hp/litre)

 

Peak and hold injectors are typically available in larger flow rates. Other than that, I don't believe there is much functional difference.

 

I'd be concerned with buying from a reputable company that will support its product, and if available, provide flowbench data on each injector they sell.

 

Good call, I didn't even address that part of the question.

The only manufacturers I explicitly trust when it comes to injectors are RC and Nippon Denso. Denso is, IMHO, better, but also much more expensive than RC. RC has gotten a lot better in recent years, though.

I've never even heard of Pico, and Bosch tends to be provide OE replacement parts, not performance parts. I'd stick with the big names on this one.

 

OEM injectors wont cut it?

 

OEM is just an acronym for Original Equipment Manufacturer. A lot of car manufacturers use Bosch (Nippon Denso as well) injectors. If you were using the same size you had now, no, switching brands wouldn't necessarily help. You could pull injectors from a fuelie Corvette and use them though, so long as they were the same style (high current or high voltage) and physical size (not flow size) as your stock ones, and they'd probably flow more. Your best bet is probably to talk to some people who are savvy in high performance fuel injection (speed shops, people who are really into scca, engine builders who build fuelie drag cars, etc.) Ask them which brands or styles they'd suggest.
I'm not trying to dog anyone here on the board, but getting information from a variety of sources helps you get a better idea of the big picture.
