evo 16g into 20g

[lowboost13]

Anyone see any good performance gains from taking an evo 3 16g and putting a 20g compressor wheel on it? I want to do it, but not sure of how much gain it would be.

I would leave it as it is, if it isnt broke slap it on and go.

Depends if you're able to use the additional airflow or not. Obviously it will make more power, but to upgrade an undamaged Evo III may not be too beneficial in the dollar spent vs. HP gain category.

It is blown, and needs a new turbine anyway thats why I wanted to do it.

Then do as you wish.

I was just wondering if you guys think if that would be a good idea for street use, because it will spool like an evo 16g but have the effect of a 20g? atleast that is what I heard.

I was thinking about doing this myself.. mine has wheel damage.

I wanted to upgrade to a TD06 compressor housing, but I wasn't sure if the eBay ones would work with my internal wastegate. Might just rebuild the E316G with a new wheel and call it good.

Interested to hear more input though.

I turned my evo 3 16g into a td05 20g. I could really tell a difference. Well worth it if you have to replace parts anyways.

A E3 16g flows 41-42lbs/min. A 20g flows 44-45. It's your call. I would just keep it a 16g
