The parts are the same, as seen by the first group of numbers in the part number.
The second part of the number is different because it denotes a different model car.
but in one car it is intercooled runs heaps more boost puts out more power so it has different components because of this
are you sure that the first group of numbers say its for a 1hdfte
ie 1HDFTE turbo and wastegate
is blabla-1 for a ute that runs 10 psi and blabla -2 for a 100 series that runs 16 psi
yes it is a turbo and yes it is for a 1hdfte but..............
they are not the same because of the car they came in
80 series 1980 hilux cab supra twin turbo engine
1hdfte 80 series
LHD fz 80 series GX
Different tunes means the part only has to withstand the pressures of the more powerful engine. So long as the part works in the 100, it will work in the 78.
Makes more sense to make one piston to handle both configurations, then to make a piston for each configuration.
You'll probably find that the same piston is the replacement part for all engines of that family back to the first 80 series with the 1hd-t, rather then having 20 different identical looking pistons sitting on a shelf for every different model of toyota that came with the 1hd engine.
The worst part about being told you have Alzheimer's, is that it doesn't just happen once.

you cannot say the engines are the same because there are so many parts that make up and "engine"
and some of these parts are the same but some differ
when you say the are the same you are basically saying you can bolt one in place of the other this is not the case
if you believe this you are misguided
why dont you try it and put it on the dyno
have you actually pulled these different variants down??
because i have
or are you just guessing
the toyota manual has different test specs listed for various different parts depending on if it were from a ute or a wagon due to the differences

1hdfte 80 series
LHD fz 80 series GX

Not according to toyota- theres different part numbers for Pistons between the 100 and 79, Fuel pumps have different part numbers, Injector nozzles are different, Turbo's are different and toyota even list two different part numbers for long blocks.
They ARE a different engine between the two.
They probably need a different part number so they can charge more for one of them.
