my garrett T4 is in need of a new front housing but i need to know what variant it is. Now the little plate on the housing says:

2300-M661
466938-548/76

Appart from Garrett that is about all it says.

If any one could shed some light on this it would be a big help.

Cheers
Tony

 

Looks like a normal T4 Comp housing with a restrictor. You would need to take it off and measure the inside to know for sure as it could of been machined anyway.
