Re: cheanging turbos by Hotshot8792

Things you will need:

10 mm, 12 mm, 14 mm, 17 mm, and 19 mm sockets
at least a 3/8" ratchet
1/2" breaker bar
A universal swival joint that allows you to angle your sockets
P.B. Blaster
All the oil and coolant gaskets, and exhaust gaskets that you take apart
Upper to lower intake manifold gasket
And maybe some misc tools and a prybar

First thing you do is spray all the bolts down with PB Blaster the night before and let them soak so they will come off easier.

Step 1: remove the battery from the car, and then jack the car up and put it on jack stands.

Step 2: Take the plastic shielding off from underneath the car, drain the oil from your oil pan, and drain the coolant from your radiator.

Step 3: Disconnect the MAS, and pull the all the intake piping out of the car. Then remove the y-pipe, all the intercooler pipes that go from the y-pipe to right across the front valve cover, and remove the hard intercooler pipe that connects to the rear turbo.

Step 4: Remove the upper intake plenum and throttle body, i like to just leave them attached together so that I dont have to worry about getting a new gasket for it.

Step 5: Remove the two coolant hoses from your radiator, one on top and one on the bottom. Then undo the 4 bolts that hold the two radiator brackets in place, then pull the radiator out of the car.

Step 6: Remove the big plastic heat shield from the front and remove the big plastic heat shield from the rear. And you probably just never want to put them back in your car again because they really don't do much good.

Step 7: Get up under the car and disconnect the downpipe and let it sit on the floor.

Now its time to start pulling the turbos.

Step 8: Disconnect the oil return lines from the oil pain, then disconnect the oil feed lines from both turbos. Next disconnect the coolant lines from the turbos. If your having trouble getting to the bolts on the turbo, then just disconnect the lines from the thermostat housing.

Step 9: Disconnect both O2 housings from both turbos. There are 4 nuts on each one.

Now the only thing holding the turbos on are the exhaust manifolds. Since the front one is the easiest, lets start with that.

Step 10: Remove the 3 bolts from on top of the front exhaust manifold, and the front turbo comes right out. Be sure to place the oil return line on your new turbos before installing them. Use the new gaskets as your putting stuff back on. The new front turbo just goes back on the same way the old one came off.

Step 11: Now there are two ways you can attack the rear turbo. If you have a TD04 turbo that uses the stock turbine housing, the easiest way is to undo the clip that connects the cartridge to the turbine housing and the bolts that hold the wastegate, and just pull half the turbo out of it, and insert the new one making all the new connections. There are alignment pins to set the turbo to the correct clocking. This seems to be the easier way.

However if you need to pull the entire turbo out of the car, there is one nut on top, and 2 (a bitch i might add) underneath. Using long extensions and possibly even the universal joint, you can get the two out from underneath, then the entire turbo comes out. Just put the new turbo in the reverse process.

Step 12: Once you have the new turbos in, make sure you connect all the oil and coolant lines, and put everything back on in the reverse order, and your done.
