great chance to use some jb weld...

Re: stupid bolt
 

im gonna have to agree with cberman. it looks a 1/8 pipe thread to me. looks like you need it to run to your wastegate

Re: stupid bolt
 

Yup, because you can really tell the difference between 1/8 NPT and an M8 bolt. I highly doubt garrett would use pipe thread anywhere on the turbo.

Re: stupid bolt
 

Yeah that looks like the nipple fitting for the wastegate. Just get a bolt and washer form the hardware store like everyone else said and use some teflon tape or something so it doesn't leak boost.

Re: stupid bolt
 

i had a 1/8npt fitting + tap hole right where yours is on my airesearch garrett 42/48

thats like saying an american car wouldnt use metric nuts/bolts on their cars...

ford automatics have metric stamped into the trans pan :1 :1

Re: stupid bolt
 

Yeah, because it would be too cost effective to use a tapered pipe thread on a fitting that needs to be air tight. ::)
