    Running the mighty TD42 i think you will be safe.
    I had a TD42 in my old GQ patrol and that was a tank of an engine, was noisy and lacked a bit of power but the low down torque was good in the bush.
    I think i should be able to pull 100RWKW and around the 400NM out of this build just e higher in the rev range then the TD.
    anyone want to make a guess on power and torque figures for when i run it up on the dyno
    Full rebuild
    W2A intercooler
    3" exhaust
    11mm mechanical pump (boost compensated)
    rebuilt and high flowed turbo standard housing on standard GU manifold
    2.5" inlet pipes from air box with no MAF
    mild head port
    around 20lb boost
    I would be interested to see what peoples estimate are.

    And this why we clean and inspect parts before we install. That is a crack that goes all the way through the water pump/injection pump bracket. If I hadn't noticed it (be hard not to) and just put it on that would of leaked coolant.
    oh well off to go and spend more money

    This is a very common issue with the RD and RB engines. the oil pump drive flats wear to the point the pump can loose drive if it gets to bad. 2 causes for this are that when the cranks are made they have to much clearance between the flats on the crank and the mating flats in the oil pump so there is a high degree of point loading instead of driving off the entire flat. the other issues is that section of the crank is not hardened.

    its not the end of the world though. i just set it up in the mil and machined two new flats with much tighter tolerance to the oil pump drive, it did have to buy a new pump and housing as the old one was heavily worn like the crank.

    I also managed to find a 2nd hand water pump housing locally for $50 so massive win there.
