bigger turbo

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.

thank you for your info

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.

The 16g is bigger than the VF 30 i believe. I think a 20g is too big unless you are going to be racing.

Almost clean wrx...

Dont skimp out on fuel ever. Thats the best way to blow the motor up, blow holes your pistons, anything you can think of.

Like the old saying goes, cut enough corners you get a circle.

In the racing world thats so true, if your gonna upgrade do it right the first time, you might shell out now, in the end tho you will have saved your money and alot of down time.
