Evo 3 or 2g O2 housing on small 16g

[noid]

I have a small 16g. I have a 2g O2 housing and an evo3 O2 housing. I was wondering which would be a better option for me.
The car is an automatic with ïfull 3 inch exhaust.

Only asking because the exhaust side of the 2g housing is already bigger than the exhaust outlet on the turbo. The waste gate side is slightly shorter than then wastegate outlet on the turbo.

That's the comparison from the 2g O2 housing and the 16g. The evo 3 housing is still at my friends housing so I don't have it for comparison.
Any advice will be greatly appreciated. Thank you.

2G o2 housing will be fine. The outlet of your turbine housing isn't 60mm like the Evo III turbine housing.

What kind of solution are you looking at for dealing with boost creep?

Just curious..

I plan on running low boost off of spring pressure. Assuming the internal waste gate could handle it. If it can't I guess I would be looking into an external gate? Or maybe porting the wastegate outlet on the turbo as well as the O2 housing would do the trick?

None...the turbo already has a 34mm flapper.

2g o2 I have one on my small 16g and am boosting 16 and about to go higher..

if you already had the 2g.. Use it. If you have access to the evo. Then do it. Then you have it for later down the road..

Keep in mind the fitment issues that can arise when using an Evo III o2 housing with certain downpipes....especially if the car is AWD.

Thank you for the replies. The car is a GST. I decided to just use the 2g. I'll have the evo3 on stand in case I upgrade to an big 16 or an evo3. Thank you again!
