2jzge-t even on 7m electronics considering i have a brand new harness and cps wiring with an aem standalone seems like a better choice money wise and power wise than a 1jz. specially considering you are getting the 3.0l than the 2.5l. now ive seen many awesome things from 1jz's and they rev happy as hell but why not have the best of both world with a 2j? throw a gte head and intake manifold on to the ge block and be set.
