I broke one of those long bolts that attach the turbo assembly to the exhaust manifold. The manifold was mis-aligned, so it screwed up the threads on their way in and the bolt seized. Live and learn I guess...

Aside from taking the manifold to napa to get the hole fixed, I need a new bolt. What material are these? Should I just get a used one or is there something I can get locally that would work?

I would suggest just getting an OEM replacement from Ray. I know the nuts which go on the exhaust portions are inconel. I'm not sure of those long bolts, but I would assume something similar.

I went to a local hardware store (professional one) and they had the exact bolts that is used on the turbo housing. I was amazed I only changed one of the bolts which was completely broken, but next time I will take the time to replace them all.

I'm pretty sure that they are the same material. Similar appearance and resistance to corrosion.

So, OEM it is. I doubt a hardware store carries inconel.

...but I'll probably just buy a used one... I just gave Ray $400 last month. hehe

I gave $1 for the bolt and it's exactly the same material and dimensions as the original one.

Dimensions, yes. Material, no. Take a look at it after 5k miles and see how it compares to the others.

I've got extra bolts in high grade, high tensile alloy, (rated 10.9). Alloy is more corrosion resistant than plain steel.

$5 a pair + shipping. Priority mail envelopes are about $5 in the US, I think, so anyone that needs some bolts, paypal me $10 at jsemak@***.net and I'll send you two of the bolts.

FWIW, I've had trouble with the stock ones too. They corrode and break or fall out. After examinaton, the stocker appear to be plain steel--so I don't think they're anything special. To get the good ones, I had to buy a box.

Perhaps, I don't know cars and mechanics. I'm almost complete with the engine installation.

But the bolts looks exactly like the original, looks to be the same type of metal/material. But what do I know, it's not my field of expertice

One quick and effective way to determine if the material is the same is to do a spark test: Grind off a bit at the end of each bolt (with a disk or bench grinder) and watch the sparks. Watch the length, color, pattern, etc.. of the sparks; it will vary with material composition. If the sparks are identical, the material is the same; if not, they are different.

The stock bolts are expensive do to being inconel. They are non-magnetic which means a magnet will not stick to them.
