3sgte engine block differences

[James Sen]

I have a 3sgte engine out of a gtt caldina in my car and its seemed to have thrown a rod or something cause theres a hole in the block now , i havent removed the engine yet to see wat exactly had happened... how i need another block... as far as i know all the 3sgte engine block is about the same at the gtt caldina 3sgte, can anyone please confirm that and does anyone know of anyone selling one....

No, they are not the same, though it may be possible that the internals will fit.

Given the likely level of damage you'll be better of getting a second hand replacement engine, repairing your's will likely not be a viable option.

well my plan was to get another block and get after market pistons and rods, would there be any difference in the crankshaft within the different generations

[Mr Revhead]

the first gen cranks in the st162 celicas etc are different

all other 3sge/gte cranks are the same

I seem to recall a certain toyota parts man saying on the forum that the crank and pistons for the ST246w 3SGTE were slightly different.

Is this the case??

I know it will not affect his finding of a second hand one but I am just being a pedantic pain in the ass. (as usual).

no, crank is the same.....

The crank may be the same, but the pulley isn't, neither is the oil pump, sump, or I think the timing cover. All these are needed if you plan on retaining the stock ignition triggers and COP ignition, though you should replace the oil pump anyway. I don't know if they will fit on another gen block.

Also a mod was done to the block that strengthened the area around the water pump to stop block cracking. While this doesn't affect the interchangeability of components as it was done for all Gen II+ replacement block as well, it's nice to have if you're planning on building a high HP engine.

Also, you will probably find that the crank is bent after the effort of punching a rod out of the block, and there will likely be damage to the cylinder head and valves. IME it will be cheaper to source another engine, than try and build one around the existing crankshaft.

I have a GT-T Crank here if you require one.........

theres a few changes... i did a bit of a look a while back..
cant recall all of them but a fast look tells me the pistons and crank are different in the st246, rods are the same

interesting.......

only thing..... it looks like toyota superceded the crank p/n.
so either i screwed up back then
or since then toyota have superceded the pre st246 crank to the same as st246.

when checking numbers on the EPC, i cant check if parts with bolt in to other places, but i can check partnumbers. the partnumber will change for the slighest change, weather it be an extra hole, or different suplier
