Turbo bolts/studs

Postby tsoob » Fri Mar 04, 2011 8:54 pm

I have had to remove my turbo again, and have removed it around 4 times in the last year, I find that the steel studs and bolts that I use get rusted and become a bit of a c@$t to remove

What other options do I have?

Just coat them with anti-seize or copper coat, that come apart much easier that way.

We use the pure nickel "Never Seez" on nuts/fasteners on the hot section of gas turbines, really good stuff. Or just copper-coat as was said above. Both are very, very bad for you so wear gloves when using though.

I've used the stud/nut combo and all I get is loose nuts falling off and all that kinda bullshit.

Changed them to Allen head bolts for the downpipe and allen head countersink for the adapter, worked a treat, pity turbo to adapter still has to be used with nut and bolt since there's no room there.
No "stance", no "hellaflush", none of that bullshit. Nothing but no grip on full boost.

Same, i had more problems with them coming loose while in use.

took me ages to get it so i didn't need to check/tighten them each race.

i would rather have them tight than not.

yep my problem is that they are a pain in the ass to get to, they are siezing, and we used copper last time..


The size of them is a challenge particually the ones on the wastegate, as you cant get a 12mm socket on them.

Also the studs with nuts that the turbo bolts to the manifold have come loose, and i have even lost one of the nuts completley.


what about stainless bolts? will they be more resistant to rusting?

Lol, out of all the nuts and bolts that hold my manifold and turbo on there is on 2 that you can get a socket onto,
and about 3 that you can't get to with a ring ring spanner
and even a couple that you cant get to with an open ended spanner properly.

It really depends on the quality of the nuts and bolts.

I tried all sorts of aftermarket types and ended up with Genuine Toyota Parts

Toyota double length nuts
909170-10035

and I dont have the part number for the studs with me.

It's not so much the rusting, it's the heat cycles it goes through, it stretches them out and when it cools it shrinks back, do this on a daily basis and they just don't like it.

This is what I use, and they don't round themselves out when you put a big booty allen key on it, never had one snapped on me (powerbar + allen key lol).

Hi Tsoob.

If you have a marine shop nearby, pop in with your 1 of each nut/bolt that you need and match it up with some of the love stainless items they have in stock.

No more rust and great quality parts.

P.S As above ^ I use a ratchet spanner and an allen key "bit" to get my WG bolts out as I have about as much room as it sounds like you have.

One of my dads mates figured out a good combo on his 700hp bmw targa/circuit car. I think he used alloy studs, and stainless nuts.

I will have to ask him next time I see him, I could be wrong about alloy but it def was 2 diff types of metals, one to expand faster than the other to make better contact.

On mine I use M12x1.25 studs and nuts off a Mitsi Evo. Cant remember which part of the exhaust its off.
M12 is an overkill but def does the trick as i've been using the same bolts/studs for over 3 years now.

copper coat or simalar metal based anti seize for heat resistant

stainless is realy good for corrosion resistance

i use "cone lock" or "con loc" nuts on myn to stop them from comming loose

or double nut if there is room
girl: can I trust you?
me: you can trust anything :D
