If I wanted to re build a B20A could I put Jap. pistons in . Of coarse these are North American motors. I would also like to get a site to go to for order #'s for JAPAN motor parts. In Canada you can't order these parts from Honda; it's the same state side too I beleive........TIA

 

Is this a side project or are you going to throw the engine in your car? I dunno part availability on the B20A but i if you can find some go for it man. I think you might find more information on 3geez.com since they are a forum dedicated to 3rd gen accords.

 

You may have to go to an aftermarket Piston Manufacturer like Mahle or TRW to find a piston you need.
Perhaps a Google search using key words like
"JDM Honda Parts Catalog (Manual)" might scare up something for you.
