Default Boring out a 2.0 to a 2.2?

I just got another 2.0 shortblock in and was measuring the cylinder wall and it is about 10.5 mm where I measured and when compared it to a 2.2 block, that wall was about 8.5 mm, a 2mm difference in thickness.

So theoretically, you could bore the 2.0 block to 2.2 and still have "factory" thickness cylinder walls.....

Anyone done it?

A standard size 2.2 piston is at 97mm I believe.

A standard 2.0 piston is at 92mm. Wiseco has the .020" and 0.040" oversize in bore. So max would be 93mm oversized 0.040". You are quite far from the 97mm form the 2.2 bore size.

You would need to sleeve it in order to get that displacement. You wouldn't want to run aluminum walls there are all kinds of issues with that. I thought most people stroke the EJ20 to get the 2.2L?
