2AZ lightweight block option., Article suggests 5S/2AZ interchangeability. Options

Be careful you don't get scammed into an iron block while in Africa.

This article suggests that the 5sfe and 2azfe blocks are so similar, that they can be interchanged.

Chances are that half your engine is actually made of cast iron engine block (5S-FE) extracted from older models(less than 2001). It recently came to my notice that these engines are rebuilt locally and sold to unsuspecting customers as full aluminium engines.

For those that are concerned about their cars balance or overall weight, this could be useful. I would be interested in building an all-alloy 5sfe. And If that is possible then a lightweight 3sge (stroker) may be possible as well.

Hmm thats very interesting, I don't see how they could manage that though since all S-series engines have timing belts and AZ-Series have timing chains not to mention all the other components used for VVT-i, i'm pretty sure the only S-series engines that have the oil passages on the blocks for VVT-i are the red and black top beams, so i'm genuinely curious to see how they get these engines to work lol
