Actually, i changed my mind. I got my stock injectors rebuilt and bought the 7th injector from URD, however i will be controlling it with a MAPECU2 instead of the URD calibrator (way better system). Everywhere i've read, the 7th is the way to go with the s/c, so i went that route.

I actually havent built the motor yet, it's sitting in my garage waiting for me to get my winter car back on the road, so i can put the 3.4 in my 4runner. I'll post up build pics next week in the main toyota forum.
Also my buddy had issues with his innovative freezing up and such, is it the innovative or is it your truck?

About the pulley, it can keep up fine. stock injectors are 245cc, so 1470cc total, where supra injectors are 305cc, 1830cc total, and they keep up with the 2.0 pulley just fine. The 7th is 660cc, bringing the grand total to 2130cc, much more than the supra injectors. SO, actually, the 7th can handle more boost than the supra injectors.
