No, they won't fit. They're completely different engines.

i know their diff engines but i figured since they're both 2.0's that they would be able to swap 4g63 pistons into a 420a

According to data on the net:

4G63:
Bore: 3.35''
Stroke: 3.46''

420A:
Bore: 3.44''
Stroke: 3.24''

Could you get them to fit? Probably. Would it be worth it? Very doubtful. Even if they would fit, they'd probably break easily due to all the machining that'd be required.

I THINK the new 2.4L turbo SRT-4/PT turbo pistons will fit in a 420a and are very affordable. not for sure tho.

They have great things for the 420a.
