You could well be right about the rods ect.

Found some info on http://www.offroad80s.com/1hdt-head-on-1hz-block-t6479.html

Looks like Pistons and rods are different. Rods have larger piston pin

Any further info still appreciated

Thanks for that
I have been looking at various 80 forums and Looks like it can be done with some modifications.

Thanks again

I was looking to do a similar mod to my 1HZ but I was lucky enough to find a low k 1HD-FT complete from a written off 1997 80 series.
While doing the research for a 1HZ to 1HD-T conversation I came to the conclusion that cost and off road time was, for me anyway not worth the hassle. The block and crank were no dramas but be careful of little items that could effect reliability such as oil spray nozzles under the piston skirts and changing the fuel pump over to suit the injection pressures of the 1HD-T injectors and the aneroid to prevent overfueling at low boost pressures. I am not sure if the oil pump is the same seeing as how you would need extra oil volume.
Having said that yes it does appear do-able but it may be easier and more cost effective to get hold of a 1HD-T or if you can find one a 1HD-FT and do a standard re-build while having the use of what you have.

Good luck

Thanks Pop

Yes I agree. I think I will rebuild my 1HDT when it needs it and not worry about converting the 1HZ.

Its just I have the 1HZ sitting in the shed and I thought it could be a viable alternative and I could take my time building it up and then swap the engines over when I am ready.

Thanks for your input
