Most Improvement?

What gives the best output into the 2004 Corolla S? Would the turbo found here http://turbodiscounters.com/html/turbo-toyota.aspx or is it better to pick up a TRD Supercharger @ Vpower.net? Price-wise I'd think the turbo is better but I guess someone is more knowledgeable than me could tell me ...

and are there any speed chips available or ECU chips that can be purchased at a non-ridiculous price... which ones are good? And where can I buy me one? Sorry for so many questions I guess that's what you could Xpect from a NoOb like me

The link you posted for turbos indicates that that company does not make a turbo kit for your engine. Currently the only Turbo kit that I know of for the 1zz-fe is the Stafford Fabrications one.
The TRD Supercharger is a good mod. The down-side is the price, the upside is you can remain under warranty if you get it installed by a toyota dealership. If you have an automatic transmission, the gains will not be as impressive.

Other Mods available for the 03+ Corolla include Cold Air Intakes from TRD and AEM, a header from KBD, cat-back exhausts and mufflers. Also grounding wires, underdrive pulleys, etc.

Do dome searching around the net to see what other people have done. Check the forums like 2003corolla.org and corolla-racing.com and check out cardomain.com.

good luck

Hey I just checked out the stafford fabrications mod is... and... from this webpage it doesn't sound like they do much Quality Assurance there... which makes me kind of scared... anybody try their turbo kits?

How are they?

Never heard of those kits man, I don't know.

As for Stafford, that one person ahd a big problem with them but his was the first car of that type to be fitted with the kit. Stafford has turbo'd a lot of Matrixes check matrix forums to see the feedback...
