My box was running lean, per the dealer, before I did any mods.They reset the ecu, same thing. It just would not stop throwing a cel for running lean.
they couldn't fix it their way so I went with the bigger injectors. Also came in handy for the Nitrous system I installed, and for the next little toy I am putting on.
The Rav 4 injectors are rated at 250 or 270, don't remember off hand. they were "donated" from a junker from 2002 I believe, again I don't have the paper work handy. They corrected the lean problem from day 1.
Nitrous. Now I know why you needed bigger injectors.
I'm not saying you are dumb for running larger injectors, Frog, I am simply saying that unless you do some major mods you really don't NEED larger injectors.
Like I said earlier, my 13 second VW Rabbit is running a VERY high compression 2.0L motor when it originally had a low compression 1.6L motor and It runs great on the stock fuel system. Granted, it's not a Scion, but I just use my Rabbit as an illustration showing you don't always have to install larger injectors.
Pandaky,
Another place to go for larger injectors should you chose to use them is Newer (2000 and up) Ford products. Our cars use the newer narrow-bodied Bosch style injectors. I believe that Nippon Denso also makes this style injector as well. Anyways, newer Fords, newer Chrysler products both use this style.
