    What box is in it now ?
    If it's got the RE4R03A then you are better off staying with that and run a few selected JR403 parts in it.

    I've got a gq auto box. Not sure of the model. Im thinking the best way to do a ls1 in a patrol is to use the commy gearbox with an adapter plate.

    It would be the re4r03a box. I would need to do work to it, then bell house, flex plate, converter etc. ???

    There's been a kit for LS conversion for years, lots of ways to skin cats but you don't need any special converters, flex plates or bell housings.
    Going with a 400 will cost you plenty by the time it's all done.
    The RE box is extremely tough and can be made a lot tougher with some simple mods and upgrades.
    You can use some of the industrial version parts if your putting over 1000 ft lbs through it.

    If you want to make it shift better look at the pressure modifier valve and regulator valve and if it was a petrol box you could upgrade the servo with a diesel one but not necessary.
    There are other things to do in the valve body if you want to make it a lot better, especially the over run clutch operation.

    There's a guy on here with a 383 and RE box in his Patrol, you probably need to speak with someone like him before opening your wallet.

    That sounds good. I don't mind using the re box, as long as its not stupid expensive. To do it on the clevo would of been just that.

    Sorry, I should add, I was going to use a 351c but many reasons why I didn't do it.

    i have the 383 with the re box and if I did again I would use a dellow bell housing as they will custom make it to suit your needs with the converters backing plate made to suit whatever the motors crank and flex plate was being used. we ended up reworking the converter to suit motor the best thing we did. the adapter plates that were used in the first place wore over time and just made vibs and noise and once reworked to the motors pattern it just make it a better deal.

    I put a SBC and TH400 into an MQ, it was easy. GQ shouldn't be all that much harder. The hardest bit was you need to change the output shaft in the TH400 which is a bit of work best done by an auto shop. Then with the right engine mounts (home made and easy) it was a bolt in using a Marks 4WD adapter. They also did the output shaft. Looking at the link above by Paulzig it uses a coupler shaft rather than a replacement shaft for the GQ, but it looks like it needs a transfer case move. Mine had it left in situ. FYI not sure about the GQ tunnel, but a B-VH trimatic shifter dropped straight into the factory shifter hole and the rod was the correct length to operate the TH400. MQ was a 4.0L petrol and 4spd.

    If I was to put an LS into a Patrol i'd be using an LS2 and 6L80E, these go into a Nissan with no need to move the transfer case if it is a manual originally, but if it is an auto you just need the manual gearbox crossmember and tailshafts. I have looked at this pretty hard as I was toying with the idea of putting a VE ute on a GQ or GU chassis and this is the identical situation except i'd be using the VE body rather than the Nissan body. Sounds hard but in reality once the body is mounted properly and the steering and brake lines sorted everything else plugs or connects back into the VE harness, radiator etc.
