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.
