I will be swapping my old stock turbo for a new one very shortly. What gaskets should I be replacing?

 

hmm.....2 oil drain gaskets and 4 copper crush o-rings....mazdatrix sells them

 

ohh and depending how bad the old ones are u might want to replace the engine to exhaust mani gasket and turbo/DP gasket...those are a bit $$ so reuse them if u can

 

I wasn't planning on pulling the manifold, so I was thinking pretty much to replace the gaskets on both ends of the turbo. What are the two oil drain gaskets and the four copper crush o-rings for?

 

oil and water coolant lines......those go bad once u take them apart....better doing it right the first time then redoing them again later on

 

normally i leave the oil drain on the turbo so only one oil drain gasket is really necessary, there is also a coolant supply tube gasket that you will need where it bolts to the LIM. the crush washers usually are reusable as are the exhaust manifold and DP gaskets but that all depends on their condition upon removal.
