Turbo to Muffler....has someone monkeyed with my nuts?

OK, I am changing my setup over the winter.
I pulled the rear bumper yesterday, and I went to loosen the nuts from the turbo to the muffler.
83, Euro turbo.
Front 2 nuts (facing me) are 17mm, and I got them loose easily.
Rear 2 nuts are 15mm?? Was that normal? Top one, no problem....bottom inside one....problem. I am using a standard socket with a swivel adapter.....looks like I need some sort of low profile socket to get a decent grip on that nut, or I will have to cut off the factory exhaust pipes from the can......
Seeing as I am a newbie, and I want to change the turbo, wastegate, muffler and IC......I am hoping that I have not bitten off more than I can chew here.....

Any advice? I have searched extensively.
I am trying to not even stress about the BOV removal and minor plumbing changes I have to make when installing the new IC.....

BTW
parts going on.....
Tial 46mm waste gate with straight pipe and .9 bar spring
KKK K27 7200 turbo
B&B or GHL SS muffler.....(not sure, no markings, used, definitely for turbo, got it for a song....)
Blownsix half bay IC kit (I have been assured fitment issues are dealt with), new production run, made last week.......

I did get the K27 adapter from Imagine Auto, so I think I will be in decent shape if I can get the damn muffler off of the car.....

That adapter is a major pain to hook up. make sure you install it before you install the turbo on the car, also get several of the o rings I cut 3 of them before I got it to go together correctly, and where did the pieces go but inside the turbo so I had to remove it to dump them back out. It's a VERY tight fit has to be to not leak. not an issue with construction quality or fitment just very close tolerances.

Use lots of penetrant like PB Blaster. You may need to use a wrench. Maybe a shorty wrench with the open end. You just have to try different tools to see what works best. Good luck!

if you go with B&B, you are going to find that the stock muffler will not work without a lot of "massaging" with a 3 lb sledge to clear the drip tank. oh, and all 4 nuts were the same (900.910.097.02)

Thanks to All.....

I have purchased some new weaponry to get at that nut.....it is definitely a 15mm though....so someone has monkeyed with my nuts then.......
Anyway, I will cut the damn thing off if I have to.....the turbo is being replaced anyway......
As for the can....I have no idea what it is.....but it has 2 indentations in it (they look factory as opposed to 'massaged') already to clear the turbo / drip tank....we shall see.
I don't know when I will have the chance to get at it....perhaps a little tonight.
Received my K27 adapter last night....just waiting on the turbo and WG to arrive now.

Thanks all, I will post a photo when done!

I don't know why but I didn't find it that hard to do. afterwards I heated up the housing and removed the studs from my old K26 anyway & replaced them with A2 stainless studding.

upon further inspection......

somebody at some time replaced the inside nuts with smaller ones, and the one I am having so much trouble with is rounded off enough that I can't get a grip on it with anything.
SO, the whole mess will come off in 1 piece, and I will deal with it once it is out.
I also can't get the inside nut for the oil feed line to turbo off.....WTF kind of tool fits in there? I am just going to undo the fitting in the engine compartment and remove that in one piece as well......no trouble really.
At least the car is up on axle stands now, so I can access things a little better......

Thanks guys.

I doubt that you will be able to do what you say. I had great difficulty removing the turbo not due to the exhaust.

If you get stuck (which I think you will) saw through the nut & stud with a hacksaw blade and when you have the muffler off you can heat up the turbo's cast iron housing with a torch and remove the stud like I did. Don't heat the stud. I used a spring loaded speed wrench to undo it (I don't seem to have much luck with stud extractors).

As for the oil line down to the turbo I used a crowfoot wrench which you fit to a 3/8" socket set to hold the fitting and then a spanner to open the nut.


Crow




Speed



Good luck & don't give up.

I will look again tonight......

but I am VERY doubtful that I can get a blade anywhere near the inside lower bolt from the turbo to the muffler.
I understand about the v-band, but loosening that seems futile if I can't rotate the housing at all to get any clearance because the oil feed line to the turbo is still on. I think loosening that oil line from just inside the engine compartment (fitting is right near the IC pipe). Removing the oil drain line from the turbo, and removing the 4 nuts/bolts that hold the inlet side of the turbo to the car, loosening the flex pipe, should free the turbo, so when I remove the muffler strap, I don't see why the muffler and turbo will not drop as a single unit?
Am I missing something here?

I'm pretty sure Merv is referring to the V band on his car which is an aftermarket product on his muffler, not your stock turbocharger. Don't mess with your turbocharger. Hence the with his post.

As I said before, removing the turbocharger for me was a complete nightmare, removing the muffler from it was easy. I think you will find it impossible to remove as one unit.
Even removing that top oil line with the bend onto the short upstand oil pipe to the turbo was fairly easy with those crowfoot wrenchs (I already had a set).
