Best luck ever...
so, i was taking the turbo off, to replace the gasket due to a leak... 2 of the damn turbo to manifold bolts snapped....
sooo i searched around on here, using the noob box on top, with no luck. What grade bolts should i be using in this high-heat application???? |
Why are you using gaskets around the turbo?
|
it had a gasket already... this is that damn already turbo'd miata that i bought. has a turbo to manifold gasket, and a turbo to downpipe gasket.
probably because of the cheap ass manifold... |
looks like a cheap thin steel gasket. i was just going to make one to replace it. but, maybe the bolts to the flange were just loose.. regardless, 2 snapped trying to remove it to find the leak
|
You're just full of stupid ideas today.
Don't for the love of everything turbo, "make" a gasket. That's a guarranteed way to failure |

Proper material for that application is Inconel or similar high-heat material. Preferred size is M10.
Call Trackspeed. Do it once, do it right. My Greddy has stainless gaskets at the manifold to turbo and turbo to downpipe. I use them, and they work fine. |

They will have all the bolts you need.
but please tell me you're not putting awesome inconel studs onto an ebay manifold |

but please tell me you're not putting awesome inconel studs onto an ebay manifold im not the original builder of this car, but i dont THINK this is an ebay manifold, just based on the pics ive seen of the manifolds. its not stainless or cast... just some thick ass steel tubes welded together.... kinda looks homemade. no cracks or anything, so thats good. BUT, even with that being said, i am currently piecing together a homemade one. my roomate is a badass welder... but i still need bolts. haha |
sounds good
|
There's lots of threads about turbo studs. tl;dr trackspeed for m10, IIRC there are some OEM 300zx m8 inconel for cheap too.
|
Damn.... $155 for those beasts...
will definitely be worth it though... looks like ill be driving the mini for the next week til i get paid. lol |

And if you buy those you can buy the oem 10mm copper lock nuts that go with it. |

You're also going to need a drill and tap because your manifold and turbo are almost certainly setup for 8mm studs. You could also get 8mm inconel studs for like 5 bucks a pop, the OEM 300ZX TT turbo to manifold studs work. And if you just had normal nuts that didnt back off you should be more than fine with copper lock nuts.

No idea. I'm running the 8mm 300zx ones. I'm assuming you can buy OEM rx7 10mm studs from the dealer or someone on an rx7 forum would know. I know you can get the nuts from clipsandfasteners.

Yo, slow down and think. They're two different things here. The 8mm studs will go right in and will likely be sufficient for anything you can throw at it. The 10mm studs are going to require drilling and tapping your manifold and drilling your turbo, but will be stronger. At some point, I'm guessing towards the transition between 8mm being good enough and needing 10mm you'll NEED stage 8 fasteners rather than copper lock nuts. I posted the place on line that I got my 300zx studs from in the epic studs loosening thread, at a price that is supposedly like 1/3 of the dealer.

if the 10's are comparable in price, ill do some drilling. if not, i would be happy with the 8's |
