removing turbo/manifold

i have an 88 t2
hey ive been trying to remove my turbo and manifold as a whole.
which IS the easiest way to do it right?
so far ive removed the downpipe from the turbo
and removed 4 nuts that connect the exhaust manifold to the block
and removed 2 bolts that connect a hardlines flange to the turbo

is that all? what else do i need to remove
because i cant seem to pull it off the block
thanks

I remove the four nuts that mate the turbo to the exaust manifold. Then pull the turbo out of the way to access the manifold bolts more easyly (sp).

The two fwd nuts on the turbo manifold can be taken off using a six inch extensiion and 14mm socket. There is room. That's if the heatshields are out of the way.

And you need to remove the two bolts on the oil return line where it mates with the pipe on the front cover.

And unscrew the oil feed line. Double wrench it. One nut is a part of the pipe itself and you don't want to twist the feed line.

Then there's the water return hose and *stuff*.

It's bound to be easier to remove the turbo first then the exaust manifold. Seems that'd be too much material going out a small space(both bolted together).

Basically impossible.
You cannot access all 4 nuts that's holding the turbo exhaust manifold to the engine.

You need to remove the turbo first.
3 out of the 4 nuts can be remove from the top.
The last one is easiest from underneath.

If you still got the stock heat shields on, you're screwed.

alright i removed another hardline that seemed to be holding the turbo to the manifold i think.
but i still cant get it out.

alright the reason im trying to remove the turbo and manifold is to get to the lower in take manifold.
but it seems like the LIM is in the way of removing the turbo.
just to make sure before i go spend a bunch of time trying to get it off
i AM suppose to (in order)
remove TB and UIM
remove downpipe
remove turbo from manifold
remove exhaust manifold
then finally remove LIM

correct?

I found it damn near impossible to remove just the turbo by itself. The oil return line was in the way of getting the top forward nut off. I removed the manifold and the turbo together and it was much easier. You can get to the bottom two and the top back one from under the car. I used a wrench and was very careful about hand placement. Busted knuckles=bad. I got the top forward one from up top after removing all the crap in the way, then pull everything off together. Of course, after you pull it off, the LIM has to come off before you can get the turbo and exhaust manifold out of the engine bay. Just remember that when putting it back together so you don't get the LIM on then realize that you had to set the turbo in the engine bay beforehand.

Frankly speaking, that is not a very good way to go about things. Just a personal opinion and nothing more.

Remove the afm and turbo inlet duct.

Remove the airpump and it's hose if installed. It's only three bolts on the pumps bracket and one bolt on bottom. 12mm wrench/socket size. Big deal.

Undo the oil pipes, both the intake pipe and the return lines.

Remove the 02 sensors elect lead.

Remove the downpipe. To do this I have to undo the exaust at the *cat back* so the downpipe will move aft enough to clear it's three attach studs.

Remove the two nuts that hold the split air pipe on and push the split air pipe down and under the car.

Remove the ACV . It's only three nuts and a hose. For obstructional removal purposes and access. Whee. A five minute job for obstructional removal purposes.

Remove the water return hose

Remove the water pipe b/t the turbo and intake manifold.

From above, remove the two fwd nuts that hold the Turbo to the exaust manifold . A six inch extension and 14mm size socket.

Get under the car and remove the other two nuts that hold the turbo on the exaust manifold.

Pull the turbo out of the engine bay thru the area where the turbo inlet duct and afm/air filter were. If the top radiator hose is removed it goes out even better. Give you two minutes to remove the hose. Big deal.

Now you have access to the four nuts that hold the exaust manifold on With plenty of room to access them. Remove the exaust manifold and lift it out.

Some simple obstructional removals like the ACV make things go easier and faster.

I'm not going to mention letting the water out because when you undo that banjo bolt on the turbo (the one for water coolinig) that will take care of the water level.

Anyway you remove it, the second.........third...........forth times are easier.

Did I mention removing the battery terminal...just in case.

Hmm.. Thats weird. We all have different ways of removing the turbo. I remove the manifold and turbo all in one piece, AND ive never had to remove the LIM to take it all out as one piece. I have all the block off plates and all the emissions stuff removed so that freed up a bit of space. But ive always just pulled it out as one piece without removal of the LIM. I did have to take off the top rad hose though.
