Turbo downpipe

Hi,

What if any is the difference between a 850 and a early V70 turbo/downpipe flange ?

there are three different downpipe, conical (early 850), straight (late 850, p1 v70), angled (later v70)

15g turbos straight,16t,18t angled.

I've got a downpipe from a 95 850 that was fitted with a 15G straight flange but it will not fit on my 15G straight flange exhaust housing which is a early V70. The V70 one has a bigger flange.

16t can be straight or angled

Pre 96 is the older type flange (conical) 96 and later is the larger flat flange.
im not too sure when the 3" angled flange came in but im sure they didnt come fitted to any pre me7 cars

When I changed engines I discovered that the engine that I was replacing was an early V70 ( had a DMF,a internal slave and a V70 cambelt tensioner )
The turbo was a 15G, someone has changed this as the small location pin in the exhaust housing was broken.
I have measured the inside of the turbo downpipe and it is 2 3/8 and the flange is part of the downpipe while the 95 downpipe is only 2 1/4 and has " running flange ".
