Was wondering if the precision gt4067r is supposed to have a seal between the compressor cover and backing plate. I called precision and they sent me seals for the center section. Before I call them back I want to see if there is even a seal on it or not as I've seen some turbos with it and some without.

Thanks for any help

Check the packing plate and see if there is a grove around the circumference of the plate where a seal would be. If there is a machined groove, that is where the seal would rest. This will tell you if youlll need one.

 

There is the machined groove around the outter edge is this what you are refering to?

 

nope you dont need one
its mostly on turbos for a carb before the turbo setup

 

If there is a machined slot where the black line is around the circumference of your backing plate, that is where the seal goes and thus you would need one.

Edit: In my posted picture of my turbonetics unit, I do not need a seal. My precision 3071r does require one though. I dont know if thats just something that Precision does on their turbos or if it has to do with certain applications/ turbo or comp housing sizes.

 

Thanks for the info guys it's much appreciated.
