ISF had the 2UR GSE, but an earlier reiteration. 6800 rpm redline and lower compression without the D4S system (direct injection & port injection). The IS500 and LC500 has the latest version with the higher compression, 7400rpm redline and d4s system.
LC is the only one that gets the 10 speed auto. IS500 has the 8 speed.
