Might be rebuilding my ute motor its a 94 but it was built 10/93 would this have the heavier pistons and rods in and if it dosnt can i rebuild a TD42 N/A to TD42T Specs Any Help And Info Would Be Great.
I Need Info On Quality Suppliers For Diesel Rebuild Kits And Parts And I am going to put the turbo kit on when i do the rebuild aswell so any info would be highly appreciated.
And Does anyone have a full list of Engine Torques Specs For Rebuilding It Aswell
Cheers Mitch

gudday
guess the question would be how far are you gunna push the engine?
If you were aiming at a 27psi monster then maybe not, but if its a normal 10-15psi build then I wouldn't worry too much about it. I have one here thats done 320,000k's and still going strong.
x 2 get a manual, they are bloody handy.
good luck

it was built 10/93 would this have the heavier pistons and rods
wasn't it august 93?
the way i tell the difference is the size of the crankshaft boss, the big one is the good/better one (30mm gudgeon's). there may be guys who know another way?.......

in NZ genuine was waaaay too expensive, go a quality jap made piston and rings/bearings. Ricon ?
Always check where they are made, there's some nasty Thai made 'kak' on the market.
good luck

I remember when Woop (nick) did his with genuine, it was really scary the price once finished, and he sat down and saw how much he had spent.

AdrainGQ spent $12G on his. Think that included a nice pump rebuild also.

Iv just rebuilt mine with a comp spec pump and few other goodies and iv spent about 18.5k so far and its not even in the car yet! So it all depends on how far you want to go and like it has already been said how hard it will be pushed and what psi you will be running. try and go genuine with as much as you can with the rebuild.

x 2 As above ... minimum go Nissan genuine valves, i couldn't find after market ones that i was comfortable installing into a 20k motor.
Everything else - you can find parts that's as good or better with a bit of searching.
good luck
