I managed to pick up a TD05 off fleabay, nice and cheap so I’ll give it a bit of an overhaul before fitting, however, the seller doesn’t know what flavour of td05 it is i.e 16g, 18g etc

is there any way of determining the type of turbo, obviously stamps or markings would be the place to start but i can’t see any on the pictures.

Is there anything i can check or measure to find out??

cheers
