Bringing up a bit of an old post but i have just finished a 2trfe into a ke70 (one of if not first done),pretty much has same block as 3rz,the height of motor was a pain to keep under standard bonnet but has factory 2 piece sump modified to fit, crossmember is lowered 20mm and steering rack lowered 30mm,the r155 fits straight in with no mods to tunnel and used the hilux diff from the 2006 hilux the running gear came from and had it shortened 87mm either side,wiring was a bit of pain as had to wire the ecu security up to use the stabdard ecu where as 3rz doesnt have security,but am about to start a 3rz turbo ke70 this week and have finished in a couple of weeks but have a standard us spec prado front sump which will need minor mods to fit in the rolla
