I'm about to replace the 7M-GE in my Mk3 with a 2JZ-GE (from a 1995 Mk4 Supra)
This SHOULD be a very straightforward swap, as the two engines are VERY similar (unlike the turbo versions), plus the N/A Mk4 also uses a W58 gearbox, so bellhousings are readily available cheaply.
I'm actually hoping the car will only be off the road for a couple of days, so I've been getting all the parts together and doing lots of research . . . however, despite all the different write-ups on different websites, almost all seem incomplete or vague about particular details ! (even IBoughtASupra‎'s write-up on here that I've just seen for the first time)
One area is the Fan . . . my 2JZ-GE has its original viscous coupler and fan that LOOKS like it will fit my stock radiator shroud OK (it's the same size as my current fan) and it also protrudes the same distance from the engine. So can't see why it won't fit. Yet several people have mentioned that I would need the coupler from an LS400 . . . why?
Also . . . people mention "modifying" the fuel line on the 7M to fit the 2JZ . . . what exactly do you need to make it fit? (I was planning on keeping the 2JZ fuel damper)
