Doing it yourself?
Do you need undersize piston rings or how does it work with a wider bore?
It's a poor show in this day and age having weak connecting rods is it not?
No, not myself way too much of noob and no equipment. Got a professional doing it. New forged pistons are slightly wider hence the rebore.
They fixed it in 2014, so the newer 1.6 turbo engines have much stronger rods.
Wow that was lucky, what kind of boost was it running to bend the rod?
I don't know anything about these engines, what power do they run stock and what are you aiming for after this?
UK 1.6 is (all figures for crank) 187 rated (US is 201), mine was 175 on the Dyno I was on, went up to about 220.
With the new pistons, intercooler, intake and exhaust I'm hoping for 275-300 on 99 ron. But we will see where it is comfortable.
Stock boost is around 14 psi, I was at 16-17 and probably looking at over 20psi.
