I'm sure i can make out AR.35 on the exhaust housing.

Bloody good eyes pal! Just been out and had a look and could just make out AR.35 and that's with the turbo in front of me! It was right in front of me all along.


I've been to specsavers.  8)

just got the turbo off and found some markings so just need to verify that it is definitely standard front and rear housings.

Rear housing is marked .35


Front housing is marked .48


Rear housing has 5 studs but elbow is only a 4 stud fastening, any idea why that is?

The rear housing is definatly t2, to find the compressor housing size you need to look at the front of the compressor housing :) the .48 in the compressor outlet is merely the size of the outlet hole

as far as I could see there are no markings on the front of the compressor housing, to tell the truth there was a small marking but I couldn't really make it out and it didn't look like it was an ar number.

Something else I noticed when I had the turbo off is that there was quite a lot of sideways movement on the turbine. If what I've read is correct then this isn't a problem as the slack is taken up when the oil gets round the bearing.

No smoke though so must be okay.

should be more than 1mm of sideways play and not any in and out movement

The sideways movement is just 'float' on the bearings.

Can't be to tight otherwise it wouldn't turn. :D

In and out movement is caused by worn thrust bearing and/or collar, usually causes smoking.
