    Finally put a new turbo in :).

    Dear Lads,

    I've finally put my new VXR turbo in including the Cooling MOD.

    As you all might now i had some issues with the Bolt's that snapped off my outlet manifold.

    So i tried to use the Bolt extractor but that one snapped as well... now i had Hard metal in the way .
    Now i had to drill them out....

    That went ok until i put the new turbo in and started to fill my coolant tank...
    At the new bolt that was drilled out it started leaking coolant water.
    So i removed the bolt to see what it was and it was the cooling channel in the cilinderhead.

    I have fixed this by using Loctite and extended the from m8 to m10.
    It's not leaking anymore however i was wondering can it do harm until i change my Cilinderhead?


    I have completely tested the car and it drives perfect without any issues...
    I did not change the actuator position as it pools like a mad man .
    Amazing difference between OLD Z20LET and new VXR turbo!!!

    Man you have drilled through the water jacket in the head I think you only have around 5mm of void left once you drill through the manifold studs, its a very tight job to do. All I can think off is the head is scrap now as the flow of water now will be filling the void up in the head and disrupting the flow and cooling. That was my worst nightmare when i was drilling mine out in the same place.

    I tested the car including the cooling system and everything seems fine.
    I have to order a new Cilinderhead, but have to wait till i get deeper pocket

    Is it harmfull to drive like this as eveyrthing seems to work fine?

    Thanks.

    I'm not in a position to say if it is o.k to drive the car, but from what my brother says who rebuilds engines says it will only damage the head even more in the worst case. As you are going to buy another one anyway then don't worry to much about it as it needs replacing.

    Well done on sorting a tricky job, just keep an eye on coolant level, temperature, condition etc.
