Default Larger bolts on the ETD Manifold?

Hey Guys,

Been awhile since I've posted. Still enjoying my Greddy Miata.


Slight problem though. I just sheared the front two bolts on my manifold. I'm thinking it's time to just replace the damn thing with the ETD upgrade. The problem is, I drilled and tapped the holes on my old manifold to M10X1.25 and had to drill my turbo to accomodate the larger bolts when I originally installed the kit.

Has anybody installed larger bolts on the ETD manifold? Is there another solution that doesn't involve buying a new turbocharger and manifold?

Thanks!

I dont see why you couldn't do the same on the new manifold...or even ask ETD if they could tap it bigger for you .

Or is there a stud that transitions from the typical m8 to m10 for the turbo?

How is changing the manifold going to fix the problem with shearing the studs? I would look first to the studs you are using before the manifold.

Are you using grade 10.9 studs?

Yeah, probably best to at least talk to the guys at ETD first. I'm not sure about the larger studs, but I'm sure they'll know. Thanks!

Jay, I have no desire to try to extract the broken bolts so it's basically a paperweight once I pull it. I will replace it with a new ETD manifold regardless.

My thought is to upgrade the bolts again on the new manifold since it was a pretty easy conversion. My 10mm bolts lasted almost 100K miles before shearing.

If you are going to toss the manifold out I'll take if off your hands

I understand going with the new manifold. I paid far too much to have one broken bolt extracted since the original owner of the manifold attempted to remove it himself and fucked it up. If anything goes sideways with this one I'll be looking at ETD as a replacement.

Honestly with the holes in the turbo being larger you probably won't have a problem even with the 8mm studs. Just use washers.

FHS,

I have a broken stud in my GReddy manifold now. It sounds terrible until it warms up. If you are serious about getting the ETD manifold, I would buy your GReddy manifold if you want to sell it. I do not want any down time on the car while I repair my manifold so an extra manifold would eliminate the time without a car.

I just ordered the replacement manifold. They do not have them in stock atm so it will be about 10 days before it arrives. I'll let you guys know about my old manifold once i get it out.

BTW, since it will be awhile before I can fix my problem permenantly, is there a temeporary sealant i can use on a turbo exhaust manifold that can slow down the leaking a bit? I need to drive my car but I do plan on babying around until i get it fixed.

Thanks!

not that will withstand the heat and stay sealed.

Thanks!

The permatex high temp copper stuff works great as a sealant. Depends really though how bad the leak is.

Cast iron stove and chimny sealant might work.
