3sge g3 from MR2 into Celica GT, How many extras? Options

[H8TRAIN]

I have access to a good deal on a g3 3sge. No tranny, which I don't strictly need. Comes with ecu and uncut harness. But it's from an MR2.

I've been searching on here and mr2oc for answers, but time is passing and I'd like to get an engine sooner than later. I need some help making a list of things I'll have to change to install the engine in a celica. I want to know the items that have to be changed, and whether they can come off the old 5sfe or have to be purchased seperatly. Here's what I have so far:

-Wiring Harness- I hear the wiring harness for an MR2 is vastly different than one for a celica.
-->Can I get a 3sge harness for a celica and plug it all into the MR2 motor and ecu?

-Power steering pump- Absent on the sw20.
-->I think I can use the pump from the 5sfe on the g3 3sge. Can anyone weigh in on this?

-Crank Pulley- The 5sfe crank pulley has a second, smaller track built in for the PS Pump. The MR2 3sge does not.
--> Can I use the one from my 5sfe? Or do I have to find one from a fwd 3sge? Between the g2 3sge and the 5sfe, I have heard that this harmonic balancer is interchangeable.

-Water outlet and maybe water pump- Getting fuzzy for me here. Anyone have input on this?

-Alternator- The MR2 motor's alternator is on it's butt.
--> Put the 5sfe alternator with the 5sfe bracket on the correct side? Put the 3sge alternator and the 5sfe bracket on the front? Get a 3sge bracket?


-What else is different?-

Thanks everyone. I'll try to update the op with info if it comes.
