    As far as I know you fit a new bottom radiator hose which t's off to the new turbo hose at the back of the turbo, then the pipe which was connected to the top of the rad goes on to the new pipe which has two outlets which runs across the cam cover , then a new pipe connects to the top of the rad and goes back to the expansion bottle beside the n/s headlight, In theory the water runs in reverse to what it did before through the turbo unit. (please someone correct me if i'm wrong) but i'm sure it does. I'm still not conviced that says maybe 20 degrees in temperature is going to make a big difference on these turbo's at the end of the day GM has designed a cr*p manifold which cracks so often on these engines so they bring out field remedys to try and fix it.

    The field remedy was for the turbos as they wanted to hold KKK responsible for crap turbo's and then found out that it was because the turbo's where being feed with hot water from the rad i must say not a good way to cool a turbo really is it Thanks must go out to Gsi Jay on this for making us aware of this

    How do you know this danny? Please explain, does the vxr turbo run a different oil pressure to the z20let engine.

    nope its just the way the bearings go on them
    the VXR turbo is a good Turbo
    say if you change the oil every 4k to keep it cleane an it will be fine
    but when the oil is Dirty full of Carbon that oil is going into the turbo at High pressure an thats not good for the bearings in the turbo
    also it will only need about 30psi

    how to i know this i asked the turbo guy that works for Saab
    he was on about using some thing to drop the pressure in the turbo
