very helpful and complete scion enthusists(sp?)

what kind of info? like, what mods u can do or how to do those mods? most aftermarket parts u buy come with instructions so it tells u exactly what u need to do. but in terms of what u can do, the possibilities r limitless depending on the amount of time u have & money. for beginners, l recommend these mods:

1) tint
2) lowering kit (do not need coilovers, lowering springs r fine)
3) new struts/shocks
4) rear sway bar (do not need an aftermarket front sway bar.)
5) catback exhaust
6) rims (not necessary, more for looks)

after suspension is done, go on to engine.
0) turbocharger (or supercharger, but those r a waste of money. either way this type of mod is by far the most expensive & can have the most serious consequences of any mod u can put into the tc. if u do not take care of ur car or do not know what u r doing, then do not go for this type of mod until u know enough about the subject & what is involved with it.)
1) header
2) pulleys
3) intake (more cosmetic than anything)
4) nos
5) stroker kit

go check out the links l posted below & read the forums. it has a lot of helpful information for modding.
