Title: Turbo Removal ------- help needed
Post by: Bullet on April 12, 2008, 01:54:49 PM
I'm selling my 90 Mclaren TSTE and I've been trying to get the turbo and X-Over out. all I really need out is the turbo so I can do the rebuild.

I bought the "Complete Kit" plus a carbon seal but can't get the darn thing out.

Yes there are bolts I have to unscrew...but how am I suppose to get at them????
5 DP bolts and the bottom one is in-accessible
the the rear manifold - the lower bolt can't be reached by a socket or regular wrench.

here's my offer - if someone can help me do it here I'll pay yqa $50 and get pizza delivered.
or if somebpody can actually find a do-it-yourself write up on removing the turbo I'll praise you forever...lol

I've had 3 guys including myself looking online for a how-to...but to no avail  :icon_frown:

Ok the lower DP bolt I'm not sure what to tell you other than get some extenstions and a few knuckle joints to get it out.  Take the cruise control out and get it out of the way that might help give you some more access.  Really you are going to want to take out the drivers side motor mount and dogbone, passenger side dogbone, primary fan, upper radiator hose and thermostat housing, all the charge pipes and couplers.  Trust me it makes it a lot easier.  I pulled my turbo out in 1.5 hours.  Inbolt the turbo at the crossover the 4 bolts on the flange.  Put a drain pan under the car and undo the coolant feed line (lower).  There is a coupler for the turbo oil feed line right around the filter/ignition coil area.  Undo that.  Undo the clamp for the turbo feedback line and take the line off the turbo.  Undo the coolant return line for the turbo (upper).  A ratchet wrench always helps in those tight spots I suggest you get one for whatever bolt head you have on the turbo bolts.  When you put the turbo back in get some metric 8 X 1.25 mm SHCS (socket head cap screws)  they have the allen head in the middle these are so much easier to get at the DP bolts with, although it is still tight. 

When you get around to rebuilding the turbo go ahead and read my how to on turbo rebuilding.  Good luck and wear gloves that turbo is a knuckle buster!

Thanks!!

If you are taking out the turbo, you should also take the X-over out, and get a new one from kenny K. Even if it doesnt sound like its leaking, or smell, or whatever,,, Its leaking. Inside that heat sheild is a fiberglass insulator. Which will muffle the exhaust sound.

like I've told others who asked...I have no money left now.
so unless he wants to do one for free I can't get a new one done.
I might be able to have new interlock flex sections put in, or possible
just make it all solid. it's kinda stupid to have it bolted to the trany...ya know.

I agree with pontiac6ksteawd, since you already have th turbo out, you are 85% of the way to getting that crossover out. Borrow the money if you need to, but you will hate yourself for taking the turbo off again. Either that or just keep the turbo off until you can afford to have the pipe done...just don't drive it. Trust me, cutting the corner on the crossover pipe is something everyone wants to do, but there are two reasons to replace it:

1) Give the buyer of your car peace of mind, helping to make your sale.

2) If you replace the crossover and drive it, you will understand what number 2 is.

Not accusing you of cutting corners to be a bad seller, just trying to help you and the next TSTE owner before it becomes a bigger problem.

if I replace the cross over I'm adding it to the sale price not including.
it runs fine with no smell of gas. if the buyer wants me to pay to repair
my x-over as part of the sale they'll have to pay for the part. I have
zero cash left and nearly $400 is way out of the "borrowing" tree.  :icon_frown:
I wish things didn't cost so much...lol

You may have siezed bolts in your turbo, when people put plain carbon steel bolts in the turbo instead of the high strength ones.  They are probably going to break off so if you don't know if a machine shop to drill them out or have a drill press of your own you may just want to sell the car as is with the turbo in it.  I mean it works after all right?  If you want to do a cheep repair on the crossover do what my buddy did.  Go to the pick a part and get a crossover from any W-body car with a 3100 in it.  Have a muffler shop chop off the bellows off the 3100 crossover and weld them into yours.  Probably cost you a grand total of 50 bucks including the cost of the crossover from the yard. 

Honestly you are not going to get that much more for the car with a rebuilt turbo.....plust in my experience you are going to cost yourself more money at this point if you try to take that turbo out........just because you rebuild it does not mean it is good.....you could have a worn out turbine shaft amoungst other problems.  If it works just leave it and make a note of the problem to the buyer.

If the turbo is just eating a little oil it could be a few things but based on the turbos I have torn down and Flybynite many are missing the oil shield on the exhaust side which causes oil to go out the back of the turbo and into the down pipe.  If that is your only problem and you are really going to sell it I would just put it back and sell it as is.  You know how it is.....oh it will only cost X amount.......and it ends up costing 4X amount.  If you are really struggling to finish this thing to sell it I would not pull it apart to rebuild it.  Is the shaft play ok?  The compressor is not touching the front housing on the sides right?  If all these check out then I think you have an ok turbo.  No brand new but considering your selling price of 1700 bucks.......

turbo spools perfectly wirth no problems, wheels aren't touching or scraping the sides. I have my buddy uploading a video of the one time I ever got on it and all you can hear is that beautiful turbo  :drool:

oil is coming from the turbo going into the intake, so I think it's the oil seal on the front side.
