what are the turbo part numbers

Back when I was racing these things I used 8374 EFR IWG turbo setups. Not cheap but they last. I think they changed the name to Turbosource from when I used them. Check them out. There are a lot of other sources now, even EBay has some.
For the average novice, go to the dealer to see a schematic of the turbos on your car, and see the parts list. That will tell you everything you need to know about parts. There are parts suppliers, like Rock Auto that have the same information..... I'll assume that you're going to have this done by a real mechanic. They have suppliers who supply correct parts. So find a mechanic who works on Mazdas just to make sure. Otherwise, if you really know what you're doing, follow the above advice about sources.
