Why would you even bother! I have a 1jz in a mk2 Supra and this is a great conversion!!!! All you need is a jzx90/100 front cut and engine mounts and with a bit of fabrication work it will fall straight in. Well mine did anyway. This is a gun conversion and I'm sure someone over there has done it by now. I know two guys who have 2jz's in mk2 supras. The 1g is an old design with not much aftermarket support. That's my 2c anyway.
