Hey guys, as the topic says looking for these parts or at least some advice on this. Did a search but not seeing anything on forged parts.

I would like to do BM3 tune but reading too much horror stories with engines blowing with just stage 1 so rather just change the internals for peace of mind and of course have more headroom for power.

Are the pistons and rods the same for 330i and 320i B48? Seeing them available online to buy but just need to confirm which one would work in my engine.

Is it simply a matter of just changing out the pistons and rods or is it more complicated? First time doing this on a bmw, not sure if its more complicated to other cars.

Thank you all for any advice and feedback.
