zenon... way too many questions to be posting... \
all the info you need can be found with a search. try searching 3sgte swap.
and it sounds like you are a complete noob, so i would not advise doing such an engine swap yourself. there is a place in texas that has experience with toyota motor swaps especially 3sgte stuff... i cant find their name right now cause the mr2oc.com is down...
slip, try that site, and try
www.toyotacelicaonline.com and
www.celica.net ... not sure what you will find with these though...
