For those wanting to RWD a 3SGE/GTE that does not have all of the block mounting holes on the intake side which is done to provide clearance for the 4wd transfer case then you can use 3sfe spacia mounts. The spacia mount puts the engine mount angle the same as the 2s mount and the same outwards dimension from the block.

Part numbers are
Intake - 12311-74260
Exhaust - 12315-74150
