Turbo intake diameter
Turbo Mini Forums

I have fitted a metro turbo engine in my mini. Now I am trying to fit an air intake hose onto the turbo but I cannot see the end of the turbo to measure the diameter of pipe that I need. Thinking of a 90degree bend then pipe over thermostat housing ? Any ideas please

I think it's 52mm od, however it depends what turbo you have . Mine is on the bench I can check for you later in the week but its a garret t3 so if yours is different the diameter may well be too.

60mm for a T3

Ah there you go , 52 is a standard gauge size lol !

It's a standard metro turbo from a 1987 car so what turbo is that

As standard it was a Garret T3 however 99% of metro turbo engines have been taken in and out and played with its no guarantee that the original turbo will be on it , having said that the T3 is capable of enough boost for pretty much any mod so most people stuck with them.

I would say its a definite to check the turbo has no play in the bearings and the fins are in good condition before running the engine, you don't want to plumb it all in and find the turbo is shagged ! I know how tight it is to get to in a mini but it would be foolish not to check this before plumbing in all the pipe work .
