Hows it going,
This weekend I took the miata to local drift event. I was so impressed how just pushing 5lbs of boost made a difference. Handled great until i realised funny noise coming from under the hood, sounded like spun bearing . When I head back to the pits, getting a few revs I find out the noise is coming from manifold. I noticed 1 of the studs is missing and blew manifold to turbo gasket. I have the upgraded etd manifold, before track event I went through tightening every nut and bolt on the manifold as well the downpipe.
Would it be a wrong idea to replace the studs with bolts using 10.9 grade and those anti vibrant washers from FM?
My dad when he came over to visit, he said that he can get a stud welded so it wont come off. This is a wrong choice right? I havent heard of anybody ever welding their studs.
This miata is my occasional dd and weekend warrior.
Thanks in advance
For the gasket a member mentioned he used grease as a gasket, having the heat burn the grease and create a carbon seal.

 

Since you searched, I'm sure you read through this thread....

What you need is Inconel studs not grade 10.9 studs. There a little spendy though, Trackspeed engineering has them. I wouldn't weld them on because once they stretch you have to replace them.

 

Got time?
Everything you ever wanted to know about connecting the turbocharger to the exhaust manifold on an aftermarket turbocharged Mazda Miata.

 

Turbo to manifold gasket? That's going to be a problem. Skip on using a gasket there.
