91 300zx TT Lots of oil smoke after boost

[Palindromas]

The car smokes a bit even when in vacuum, and then after building up any amount of boost and letting off, a big smoke cloud will come out of the exhaust, the more boost I build up the bigger the cloud that comes out. The smoke seems to be coming out of the passenger side turbo. I'm thinking it's a turbo seal. I was mainly wondering if anyone had any other ideas on what it might be and was wondering if this was a possible diy fix or if I should take it to a shop.

First and foremost, welcome. Second, it sounds exactly like the seals are going. Third, really its up to you whether you need to take it to a shop or not. If you have the ability to do the work than there is no reason to take it to a shop unless you don't have the time or desire. If the seal is gone you will need a new turbo or at minimum a CHRA that you can use the housings off your old one on. replacing the seals (whether yourself or through a shop) will be an exercise in futility unless the shop is a specialized turbo shop with the ability to high speed balance the assembly.

So basically, you're saying that I am going to need a new turbo? What are some good places to look for a stock z32 turbo? I've only been able to really find anything that looks reliable on z1 motorsports.

[NolimitZ32]

If the turbo is the culprit then yes you will need to replace the mechanical part of the turbo. Z1, Specialty Z, Import Parts Pro, Concept Z Performance, all of these sell the factory CHRAs and full turbos. Going directly through Garrett/Honeywell may prove problematic because the factory t22/25 turbos were commissioned by Nissan and built specifically for the Z32.

Would it be smart to also get a new wastegate actuator, new oil lines and new gaskets for it as well while I'm changing it out?
