I have 2 choices and im not educated enough to make the correct one
Same compressor but differnt exhaust side
1: T3 1.06 A/r
2: T4 .82 A/r

will the T4 .82 ar flow as much or more because its a T4
or is the t3 1.06 ar a better flowing housing because of its larger ar despite it being a smaller housing.

 

What turbo specifically? Because the Garrett GT series is essentially a "T3"... but with a bigger wheel...

 

its a gt35r
it is now offered with a t4 tang housing.
i have the t3 version allready but the company i go thorugh offered to swap it out for free if i was interested.

 

It's not a GT35R if it's offered with a T4 tang housing.

 

yes it is.

I am not sure if the t4 version is ball bearing, though.

edit: Ooh, it is.

 

the question is
is a t3 1.06 a/r capable of flowing more than a
t4 .84 a/r

It looks like the T3 flows more if I am reading that right.

 

i think that is for the t3 version. garret doesnt make the turbo with a t4 so it wouldnt have any charts far as i know.

 

I was thinking the same thing actually. That's a hard call, maybe call and ask someone there.
