JZ Oil Pump Comparison

Differences between the oil pumps used on the various JZ engines. GE, GTE, Non-VVTi, VVTi, 1jz and 2jz.

1jzgte (most commonly found on MK3 Supra, JZX81/90/100/110) 15100-46030

Non-vvti 2jzge (most commonly found on 93-95 SC300, GS300, MK4 Supra) 15100-46042

VVTi 2jzge (most commonly found on SC300, GS300, IS300) 15100-46091

2jzgte and VVTi 2jzgte (most commonly found on MK4 Supra, Aristo) 15100-46052



You can see the lack of provision for a crank position sensor on the early Non-VVTi GE vs GTE (VVTi GE has the provision, but is still internally different from the GTE)
