I think I'm going to be rebuilding a set of stock twins with the turbo city rebuild kits ($150 a peice). But the remaining problem lies in that the Secondary turbo turbine housing has a large gaped crack between the main port and the pre-control port. Where is a good source (other than mazda) that I could find these in good used or new condition? Where are the turbo rebuild places getting them when they're replacing parts?

Thanks

 

I called turbontetics and they say that no one sells the housings for the fd twins. And the dealer only sells the complete twin turbos.

 

Find a good welder who can perheat the part and weld it . Then have the gasket surface milled level .My mechanic has had several sets done .

 

I have 2 sets of stock turbos. One set was on the car until 55,000 miles. They worked fine, but I upgrade to the 94-95 type, as I had a boost problem related to my own stupidity swapping out the vacuum hoses, and replaced them thinking they were the problem. The car now has 2001 J-spec turbos, replaced at 60,000 miles. The car has only been run at stock boost, as my wife and I competed in SCCA autocross in Stock configuration, until this year, when we moved to SM2 and upgraded the turbos to the J-spec. I will sell you the old set for $100 plus shipping. It does have the typical crack on the external exhaust housing. I will sell you the the newer set with 5,000 miles on them for $450 plus shipping. I can send pictures if needed.

Thanks,
