Toyboxx, do you have a picture of your 1JZ Soarer PS reservoir handy? I might be interested but I want to compare it to the MKIV TT PS reservoir I have first. I found a thread just yesterday detailing how someone used it on an SC GTE swap but from the look of it he had to bend the mounting points to do it to get a seemingly useless protrusion to fit between the shock tower and the fuse box. I have been wondering if the 1JZ Soarer reservoir has this second protrusion.
I also was looking in to this for my swap and after some research I've confirmed that both the TT and GE pumps or reservoirs should work for the 1JZ with some modification. Below are two threads confirming this. The CL one is more detailed:
2JZ-GTE pump works, but with some modding the 2JZ-GE pump can work as well. Need to swap out the resivoir with the 1JZ feed fitting and remove the bracket off the back of it. Don't forget to replace the bolts in the back otherwise the pump will leak...trust me, i know
^^ Yep. The pumps are nearly identical. You have to buy a nipple from Toyota when you remove the GE reservoir.
It's just that I have an MKIV TT PS reservoir in my possession and it did not appear to just fit in place as you'd expect it to. This led me to investigate whether or not the 1JZ Soarer reservoir did in fact have different mounting points. I still don't have an answer to my query but I'm sure I can make the TT reservoir fit.
It seems you have to remove the little thing that looks like a horn (from the SC shock tower) and bend the metal of the TT PS reservoir around the shock tower to mount it. Rubber bushings seem to be needed but I haven't been able to source those. I was able to source the OEM bolts for the correct length and size.
