Dorio86: the correct term is staged injection - as mentioned in my original post to this thread - one smaller injector and one larger injector per inlet tract.
I've only ever seen this on cars with massive forced-induction systems - it appears to suit longer induction paths (like the inlet and TB for a turbo 20B in a drag car for example) than a short path like an 4AGE with ITBs
on the megasquirt forum (www.msefi.com - which oldcorollas and myself and other toymods users have lurked/got-involved for a few years now) there are a growing number of heavily-modified-engine users running multiple banks of injectors.
unless you were going to run your 4age with large amounts of boost (or something even sillier like convert to uber-low compression and race fuel and/or methanol) then i really can't see staged injection doing anything for you except have the ability to run massively rich, have less top-end power and coke up the head, zorst valves and zorst system prematurely.
cheers, charles.
