OK i have two questions
1. if i got the 16g for my car could i get away with not changing anything like fuel injectors? i read it is only a little bigger then ours. i will have a downpipe, up pipe, catback, and AP on my car before hand.
2. whats bigger the evo 20g or the IHI VF30? im thinking the 30.
No, you have to have larger injectors. The stock ones are at almost at maximum duty as it is. On top of that you need a larger fuel pump. You might be able to get away with modding the stock injectors, but I cannot give you information on how reliable or how safe that is.

If you go to the dreaded Nasioc site. And search 16g there is a thread that has alist of turbos from 16g to 20g and the ihi series. Not sure how good the info is but it will give you a ballpark figure to work with.
