What's the easiest way to get the turbo off a turbo IDI?

[ghunt]

I'm trying to pull the turbo out of my truck because I'm installing the ATS upgrade kit, plus rebuilding the turbo (it has a little more play in it than I'd like).

I got all the heat shielding off and the downpipe disconnected. Oil line is removed and both bolts are out of the oil drain/mount thing.

The bolts holding the turbo to the "up pipe" look impossible to access except for the top two, and they're totally rusted anyway. I was kinda hoping to pull the turbo out, up-pipe and all, if I could just get it off the slip joint on the exhaust. I also don't really see how the intake "hat" comes off, does it have to come off with the turbo?

Any advice?

BTW is there any reason I couldn't run a -4 AN line for the turbo oil feed line? The line that's on there seems a bit large, I'm running a -4 AN feed line on my Thunderbird which has a T3/T04E hybrid on it and I have some extra -4 AN fittings laying around.

I have never taken the turbo off my truck, so I can't help you in that area. However, regarding your intake hat removal question, I can. All you need to do is remove the bolt in the center of the intake hat, and then on the turbo center section you'll see a 'clocking ring'- loosen the bolt holding that fast and you can rotate the turbo around as you remove the intake hat. There is only one o-ring keeping a seal between turbo and intake hat. If you don't loosen the turbo clocking ring thing, you will never get that intake off. I figured that out the hard way...

i took my turbo off my truck to put my ats stuff on, the bottom two bolts look impossible to take off. But with a little patience and heat you can get them off. I have a torch set up in my shop and what i did is carefully heat up the collecter where the two bottom bolts go through and they turned right out. Also if your putting a new exhaust housing and wastegate on it, the bolts that bolt the wastegate to the exhaust housing on mine took a 5/16 12 point socket and make sure its a good Quality socket.

You're talking about the bottom two bolts on the turbine inlet right?

How'd you get at them? I can't even see how, and that heat shield is in the way too.

I'll have to have another look at it this weekend.

You may need an obstruction wrench to reach those ( C or S shape ) or a socket on the end of a stack of woble extensions from underneath.
Get a can of Aero Kroil and soak the daylights out of the rusty fastners for a day or so and they'll give you a lot less grief coming out.

I used a 6AN aeroquip line for mine, I would think a 4 would be OK. Just measure the inside of the factory oil pipe and see if the 4an is that or better.
