Where can I buy new and cheap parts for Celica?, Piston ring, valve.. Options

[Iceman22]

Hello, I'm owner of one Celica with 7A-FE engine, and I got a problem that it is drinking very much oil. I have heard that this is a widespread problem with this engine when it has passed over 100.000km (at least in Norway). The problem is that the parts are very expensive to buy, and I wonder if someone could tip some stores that are selling new parts for my car, and that send to Norway. I'm not 100% sure what it is called in English, but I think it is "Piston rings" and "Valve" if i have translated it correct (please correct me if wrong). It is at least those parts that are very high chance that is causing not normal consumption of oil. The parts are not big, but it takes very much work to get it changed. Hope you guys can help me and my celica baby

Ok, but I now consider to import one Celica (one in good condition or one that has been crashed but engine OK) from US with 3S-GE engine and replace that with my 7A-FE (europe version).
I know that a 3S-GE engine would fit to the engine room, but do any know if the US engine differ from the European one?
