Ok so ive looked all over for this detail and cant find it so just to confirm once and for all for everyone what is the AR on the side of manual turbos?

 

I take it Auto ones are AR 48 but so far i havent found anyone with manual tubs to confirm what the AR is on them

if you don't get an answer before i go to my car at weekend i'll check on mine as i've got a few dead ones and some spares :D

cheers i never looked at the manual ones to remember but im sure i have some manual ones in pieces

As far as i can remember it's 60 or 64

just had a look at that and they have auto ones down as 54 not 48 as we know it? It does seem that everyone has auto tubs lying around but not manual ones

im sure i have manual ones in my garage will check tomorrow

48 seems too low to me, the difference between the manual and auto AR was only ever around 10 from memory.

i have a set of turbos here now they have A/R 48 on them and that is the same as everyone that has offered me tubs so far. Maybe the yanks are working on different measurements as usual. I havent seen a manual tub in a while so i cant remember the number on the side

Copy and Paste from one of my older posts :

 

Auto Turbos - A/R = 0.54

Manual Turbos - A/R = 0.63

 

Auto Camshafts - 240 degree intake cams & 248 degree exhaust cams

Manual Camshafts - 248 degree intake cams & 248 degree exhaust cams

arnt the turbo hybrids anyway hence the casting marking of ar 48 but have been re machined to ar 54?

Your looking at the Compressor housng, which is 0.48 AR for both.

 

The difference between auto vs manual A/R is the Turbine(exhaust) housings, and I dont recall it being printed on the housing.

Oh gotcha so how can you tell if they are manual or auto?

Ok so autos are .54 and manuals are .63 so i found this to work it out :)

This should help people figure out what they have

Finally an answer for everyone to find out what turbos you have here are the part numbers courtesy of Mike at MJP :)
