    Tdo4 turbo?

    Hey guys I've got some questions anout a Tdo4 turbo I just bought.

    Firstly I'll tell you what I'm doing with it. I'm putting it on a toyota motor. It's a 1G GTE 6 cylinder 2 liter twin turbo motor. The problem with the stnd turbos is that they are very small and the stnd manifold setup is very restrictive. I figure this turbo would be a good match as they are both 2 liter motors. I want boost on early and this toyota motor is known for being a bit breathless so I figure it's smallish size will help.

    With that said I need some photos of the oil & water lines on a complete turbo. On mine it looks like there was a join between oil feeds where they screw into the body. One of the lines is not present anymore (I'm assuming it still in use on the original car) there also seems the be a water pipe missing. So some photos of a complete unit outside the car would be great.

    Q:
    At what rpm do these turbos start to feel out of puff on a rex?
    Would you recomend them as a decent turbo?
    This one has apparently had a rebuild 1000K ago, off MY01, I got it for $300, any good?
    With these turbos are you able to move the shaft AT ALL side to side with your fingers? My older turbos do this, while this turbos shaft doesn't wabble about at all you can make the shaft move side to side if you push on it, is this ok?

    And last but not least can someone indicate which oil & water lines are in's or out's

    Thanks for your help guys!

    Sorry I can't be of any help, but if a search here does not find you the pics that you need, I would suggest checking the other forums out there, namely NASIOC.com and i-club.com
    You might find the pictures you need there....

    1. Around 5,000 - 5,500RPMs.

    2. I would recommend it only if quick spool up is of paramount concern and if the turbo it is replacing is even smaller!

    3. I've seen them go for between $250 and $350.

    4. I believe a minor amount of fore-aft play (in the direction of the shaft axis) is ok, but there should be none side-to-side (perpendicular to the axis of rotation).

    5. Oil: Top banjo connection is 'in', tube pointing straight down is 'out'. Coolant: You have two lines on the side of the turbo, one that curves over the top, and one that curves underneath. An educated guess is that the lower one is 'in' and the upper one is 'out', but double check this info with someone else.
