300TDi turbine exhaust housing size

[up2nogood]

Just looking to fit an old VNT in place of the stock hair dryer.

The one I have is a Garrett off a 90's Dodge. The inlet housing is the same AR as the Rover Garrett, .48.
The Dodge exhaust is .63.
The Rover exhaust is .47.

Any one know what the doifference on the exhaust side will do to the way it will work on a 2.5ltr diesel?

Presume you have a VNT25?

The exhaust side is variable, it should close up to at least as small as the rover housing and should open up more for better top end.

Do it and take lots of photos.

Yep, VNT25. New old Garrett stock.

Made for a petrol 2.2 litre 4 banger. Although it worked best from 3,000rpm up. Given fabricating a manifold is quite a job, I'm wonder if I shouldn't just pinch a turbo off a Merc Sprinter and graft that on instead?

Another reason to go the Sprinter turbo is last night, when rotating the inlet housing to where I needed it to be, I managed to chip a 1mm square chip off the turbine wheel on the compressor side... Bugger!

Don't suppose I can be bodgy and remove a similar amount off the opposing side....?

Oooh bugger.

Do you think they have a special turbine or are they a standard T25 wheel with just external vanes?

I think (hope) it's just T25....... 'Spose I'm gonna find out soon.....
