    Hi, I've recently been in talks with a friend of buying his LS2 out of his VE Clubby and swapping out my LS1. The engine has all the mods I need and makes decent power, but what exactly will I need to fit it and get it running.
    As far as I'm aware I'll need:
    -Cable throttle body (102mm for bigger manifold)
    -Wiring harness adapters

    Is the mounting the same for the gear box?
    And in regards to the wiring adapters, what adapters am I looking for?

    If there is anyone who has done this swap I'd love some advice.

    Cheers.

    Do some research on the Reluctor wheel, from memory the LS1 and early LS2 had a 24 tooth wheel where as the later LS2 had a 58 tooth wheel, memory is a bit sketchy, if it is different you have to either change the wheel which means removing the crankshaft or you have to get a converter box to change the signal, so that the PCM can read the signal from the wheel, from what I have read the converter boxes can be a bit temperamental.

    I do remember reading something about the different amount of teeth but thought it was on the other 6.0Ls like the L98, will definitely make sure I check now though. Would probably be easier to get an adapter than swap out the crank.

    there are a few small things like i think the dipstick is in a different spot and could be in the way, may be same in vy but i can remember my mechanic was putting a vz ls2 into a ve for a customer and there was a few small issues like that, so just look around the engine and see where everything is situated, belts, pulleys, starter, a/c compressor, oil filter is at the back in ve, sump is different, ve alternator charging is run by the ecu not like the vy...

    Your LS1 sump and pickup/windage tray will fit the LS2, but as stated, you will have to relocate your dipstick.
    Some are in the block, some in the sump.
    I think you will find that the LS2 being a GEN4 engine, will have the 58 reluctor wheel.

    Will having the dipstick in a different place to the LS1 be bad though? Or is it in a hard spot to get to while in a VY?
    I had a gander at the reluctor wheel teeth and only pre '05 LS2 are 24 tooth.
    In regards to the alternator, what can be done about that? Any way of changing that?

    Thanks heaps for the advise so far guy!

    Going from a rear sump(VE) to a front sump(VY), so dipstick needs to be relocated to suit the sump.
    Early LS2 engines were only in VZ HSV. All should be 58 tooth regardless. VE LS2 has different ECU to VZ LS2.

    Pretty sure this is correct from memory.
    VZ LS2 use the same reluctor wheel as LS1's while the VE LS2, L76/98 use a different reluctor wheel, can't remember which is which.
    VZ LS2 uses an E40 ecu while the VZ L76/98 6.0L and VE V8's use the E38 ecu.

    The VZ LS2 ECU is one of its own. Not on any other Holden. I maybe wrong on the reluctor whell, but my info says all GEN1V engines have 58 tooth.

    i know u can get the old style alternators for ve so could be worth a look or i dont know if the ls1 alt fits ve system, does the steering rack get in the way since ve rack is in front of the engine not behind...

    Thats a good call on the steering rack, I think it should be alright though, but will definitely look into it.
    All GenIV's up until '05 used the 24 tooth, so that will need to be replaced. There are kits to change that and the camshaft sprocket to the LS1 style, the alternative to this is an electronic converter box that lets the ECU read it. Though I've heard mixed reports on the converter boxes.
