Message The life expectancy is never as long as new CHRA (center cartridges. and I highly suggest new GARRETT cartridges.. not off brand etc.

I have dealt with FULLRACE before.. I actually purchased my GT28RS turbos from them. They gave me the best price.

If Z1's comes with NEW GARRETT center cartridges (CHRAs)then I dont think it would be an issue.

But if you purchased new garrett CHRAs.. you could easily install them yourself. I believe there are 5-6 bolts on the compressor side and 5-6 on the turbine side.

Do it right the first time.

Adjustable actuators insure that both turbos are "on the same page".. It allows you to fine tune the preload put on each actuator/flapper door.. (controls boost).

To be absolutely correct. It is recommended that you do this modification to the turbine housing on the driver side turbo. The goal here is to make both turbos work the same/together.

Here are two links that should help you out a bit...
