What size washers i need for exhaust manifold gasket and turbo inlet?

[talontsiboy24]

Just wondering what size washers i need for turbo inlet gasket and for the 2g exhaust manifold gasket? 14mm? copper crush washers or turbo lock washer which ones are better?

these dont say a size but will they work for the manifold and turbo inlet gaskets? Street Tuned Motorsports.com - Rochester NY

The bolts from the exhaust manifold to the turbo housing get two of those cupped washers per bolt.
They go on with the cupped sides facing each other and act like a spring to keep the bolt in tension as it expands and contracts from the heat.

This is how the 2G's were done and is recommended for all the cars.

The bolts are 10mm x 80mm (MR132656) and the washers coned disk 10.5mm (MR187848)

DSM OEM Turbo Bolts & Washer Kit- DSM: BoneHead Performance looks like it's exactly what I'm talking about to bolt the turbo to the exhaust manifold. Also get some 2000F anti-seize for the threads and the correct sized gasket for between the two.

If you haven't changed the studs for mounting the manifold to the head you want to replace those too.

yea i ordered some new studs for the exhaust manifold but they didnt come with the washers so i need to know which ones to get?

and the boneheadperformance link doesnt include the nuts for the bolts would u happen to know the size for them?

 

[ramsack]

the turbo inlet ones are m10x1.25 and the exhaust manifold studs on the head are m8x1.25 threads.

 

[steve]

There are no nuts for the turbo bolts. The turbo housing is threaded.

 

[ramsack]

1g's came with a single stud in the exhaust manifold for some reason. my guess being as the stock bolts might bottom out in the one hole, but with those conical washers, it should be safe to use bolts in all 4 corners.

 

[steve]

It's SOP to remove the stud and use the bolts so you can remove the manifold without having to remove the turbo too.

so the turbo to manifold bolts dont use any nuts just washers? they just screw right in and thats it? even with a 2g manifold and big 16g turbo?

nickel anti-sieze seems the strongest 2400f ill get some of that stuff so just apply it on all the threads?

Look at the diagrams again. The two washers per bolt get between the bolt head and the manifold.

I just bought this kit from stm STM DSM OEM EXHAUST MANIFOLD STUD AND NUT KIT

but as u can they dont come with washers which sucks thats why i asked if that link above were the correct washers to work with this kit?

 

[steve]

A 6 bolt head uses 8mm studs so get some 8mm stainless washers at the hardware store.
