Gt2860-5 Exhaust Port Size

[sickr33]

i want to know the exhaust flange size on the gt2860-5 turbos

i believe them to be T28 (50.5mm by 39mm) but can any one confirm.

i want to port my manifolds before i pull the turbos off the car to save time

also has any one posted the head side of the manifolds????

just use a new gasket for a template

yer i could do but that doesn't mean the flange port on the turbo's are going that exact size

what i would like s for some one to actuality measure the port size on the turbo if someone has a spare turbo laying around

cheers

I had someone do my manifold flanges and the used the gasket as a templete to check. Turns out the manifold flange opening is now slightly bigger than the turbine flange opening. I can check the measurements in the next couple of days as all this stuff is lying around not on the car yet.
