Best estimates i have heard so far are about 150 kgs for engine without turbos and manifolds, even if total weight added up to 200 kgs that would be about 400 pounds way less than your quoted 700 pounds.

Your estimates are well known to be completly wrong.

Not as wrong as saying a 3 liter inline six is heavier than a 7 liter v8

Besides The block itself even though it is made of cast iron is only about 70 kgs, the head and crank are about 50 kgs in total and the rest of the stuff pistons, rods, covers, brackets, flywheel and sump add up to be 30 kgs with a generous margin of error
Adds up to 160 kgs not far from my given estimate

no. the block itself is closer to 150kg.
again, you're wrong.

That would mean that a 2.6 short block built for some heavy assed modifications is lighter then a datsun 1.2 litre short block.

Lets see your source of information or is like usual you dont have and are making some extremly poor guesses again.

you mean to tell me that the block is 300 pounds

the rb25 with the transmission, cross member and rack weighs in at 700 lbs
the 2jz alone comes in at 590 lbs
Complete Engine Weights Table - HybridZ

By this data i would assume the skyline motor would not even be close to 700 lbs and the block cannot be more than 200 pounds, But even if you are right and the block weighs twice the weight of a normal human i.e. 300 lbs ~ 150kgs , i would doubt that all the rest of the engine would reach 400 lbs~200 kgs

How many times do you have to be told displacement is not weight or physical size of the engine???
240SX Detailed Engine/Tranny Info
"Engine/Trans. Weight: 790lb "
I guess you forgot the fact that the engine has 2 turbos and all the piping to go along with them.

rb25det5=half the turbos=half the piping and a much much smaller inter cooler also the gearbox is considrably diffrent as in it isnt an awd one so no trasfer case. The sump is larger and holds more contents same with nearly anyhting fluid related on the motor and hell even the distributor is much larger in this car if the rb25 weighs 590 lbs (267kg) please tell me why it couldent.

Also you conversions are deathly inaccurate 300lbs=136kg and its painstakingly obvious you are taking this from off the top of your head and you are scouring old internet forums that have been long dead in a queast to prove yourself right.

Thats made to the size of its enourmous twin cam head with 24 valves as opposed to 16.

I was using an estimated ratio of 1kg~2lbs which is abit innacurate i guess, but i find it hard to believe that turbo plumbing and intercooler diffrences add up to an almost 150 lbs diffrence, If we were including tranny in total weight in the first place then the 790 lbs estimate is very logical, however i do not think that block weight for the rb26 is 150 kgs.

yes, so as previously guessed by everyone else you don't actually know.

that 721lbs wieght was not 'assumed'.
it was from putting the engine on a set of scales.
