Help needed - engine swap - turbo vs non-turbo

[phyodor]

Hi everyone!

I have a 2002 volvo s40 b4204t3.
Had to replace this engine, and apparently i got a b4204s2 instead. But I replaced only the block and the head, all the attachements, ECU etc remained from t3.

So my question is - wether my new b4204s2 engine block will survive the t3 turbine?

Compression ratio is 10.5 vs 9 on t3

and the pistons - are they different?

Whats the risk of detonation? etc

Thanks in advance!
