Engine Conversion Rb26 R34 Gtr Help

[Ultimate_R33]

Hey guys, i had a quick search around and could not seem to dig up anything specific to help me out, basically I have a good chance to buy a 580hp RB26 that is currently in a R34 GTR. The car it will be going into is a R33 GTS-T S1 which still has the RB25. My main concern is will all the electrical plugs, loom, coilpack wires etc be compatible? Also will my Apexi power fc run the RB26? it is the one with the AFM. I have over-heard some people saying that the RB25 sump will bolt up to the RB26, is this correct? The engine will come with waterpump, alternator, power steering, aircon compressor pump/pulleys etc, what ones do I use to make it the easiest possible swap? If you know anything else that I will/may have trouble with or need to modify something can you please throw up a comment. Thanks in advance, Ryan
