Wiseco?...Why not?
Usually........you go with a bit higher compression or bore. It is probably ligher(maybe, wiseco's are heavy). But mainly, you are replacing the stock(junk) piston....with a good quality one. My guess is, basically no performance increase. Also, I've heard(not sure if true)......that those wiseco's off ebay aren't good pistons.....like you would buy from Wiseco(I've heard they are rejects.....yet still will run). Not sure.

I think there are easier and cheaper ways to get performance other that a piston swap. Have you looked into clutching, jetting, and you mentioned piping it already. I don't think I'd be tearing into the engine unless I was going to be putting cams and a higher compression piston in it. A good clutch kit will make it feel a lot faster.

I'm not too crazy about big bores. If I pulled my cylinder off and there was no marks in it, I would just hone it and slap a new piston and rings. The performance gain from a 0.020" bigger piston would be minimal, but higher compression is where you'll see a difference. Just be sure to run high test in it!!
