2002 S40 Engine Issue: S Vs T
 

Hi everyone!
My first post here

So I've replaced the engine (i had a b4204t3) and it turned out later that apparently they installed a b4204s instead.

They're all the same except for the pistons heating - so I was told. The turbo (t3) engine had special jets to cool the pistons while the S engine seem not to have those.

Does anyone happen to know if thats right? And could it overheat my b4204s?
