hy,
just like i see in the following site in paragraph 4, it says that toyota only built one same block for 2 generation of 4AGE and 4AGZE...
site: http://shell.deru.com/~sgn1/AW11/4age.htm

What i wanted to know is if thats rigth, and if the block is exactly the same ( piston, block)

Thanks

no, that's not right.

there was the early block and the later block. The early block was the bigport 'bluetop' 4age's found in 85/86 cars (and some 87 cars). Main difference is the rod journals were smaller (40mm). Starting at somepoint in 87 they started using the larger journal crank (42mm)... which that block is the same for the 4agze, the bigport 'redtop' and the smallport 'redtop'.
