Bolting it all together
What do you guys run for bolts and hardware? Like from the manifold to turbo inlet, the bolts that hold the turbo together and important stuff like that. I know anyone can go buy some ---- bolts and run them. But I am talking about long term hard use, hardware ---- has caused DNFs for me before. Are any of you running anything trick?

Graded bolts are for important stuff like heads, engines, suspension and wheels, you can use crappy grade stuff to bolt a turbo up to the manifold and it should hold up fine, I use home depot nuts/bolts/washers...I think they are graded as 2.

good bolts for turbo and all The HOT stuff are very important.
i found the bolts that are shinny or yellowish like honda bolts are generally not appropriate to bolt a turbo, they end up slacking with heat and you most of the times tear the threads off when unscrewing them.
stainless bolts are no better. They are more prone to seize with thermocycling. However they are perfect for non heating applications like the compressor cover and oil drain.
for manif, wastegate, downpipe and turbo, the bolts I prefer are the black ones. it's not always possible (to me) to determine exactly their grade, but my rule of thumb: they're never shiny and always black.
Also, you never use lock washers on hot parts. if anything, only nice, thick, flat washers and i like those to be black too. not shinny.

Re: Bolting it all together
All good stuff. My problem has been looseing of hardware all over the car. Running solid mounts and out on our bumpy tracks I think cause things to loosen up. I guess I have to check them more often. I hate nut and bolting cars at the track because it's cold.

PS I ordered some nordlock washer which seem pretty trick and I have used them for rotor+hat hardware with good results. http://www.nord-lock.com/default.asp?url=51.16.37
