    No. How many threads should it have? Standard turbo. Got the car in may & the turbo had just been refurbed.

    Pass on that one, i have just bought a gauge so don't know what mine is putting out yet. I am on stage one with a zlet tubby. will be able to find out when my gauge arrives and i can get it wired up.

    When it had the turbo done did they upgrade it to the 360 bearings? If you have the receipt for it have a look. Might help someone on here give you the correct info to what you should be boosting at
