[bertrenolds5]

I don't want to mess it up and I dont have a 90 degree drill so i would be willing to pay for help if need be but i am sure someone will help me. Pm me back.:usa1:

Are you tapping for an EGT probe? If so, it is very easy, all you need is a regular drill, some tapping oil, a HSS drill bit, and a tap. Let me know if you need the correct sizes too.

I bet he is tapping an exhaust manifold bolt that snapped off in the head.

It's best to remove the manifold and radiator. I bought a right handed drill bit and was able to remove it with a normal drill.

I was drunk when I posted this last night but I am upgrading to 2 10mm exhaust mani studs on the ends of the mani. I have all 8mm studs right now, none are broken. I already have everything off, the exhaust/turbo/manifold so I figue I might as well do it considering I'm getting a 2g mani and I already have the studs. I just need to find a 90degree angle drill, maybe rent one or something and be really carefull when I drill.

Or just use a shitty drill bit cut short...

And since there is a big pilot hole there already, the drill bit will pretty much align itself. Just get it relatively straight when u start, and you'll be fine.

JUST DO IT!

Why are you even "upgrading"?
Its not like the 10mm bolts are gonna hold that much better. I dont think it would be worth it. You can just use the 8mm studs on a 2g mani. Thats what Im running.

[bertrenolds5]

I know I could stick with the 8mm but I already have it off and I've got the the 10mm kit. 10mm studs equal less stress on the head, and I believe that it can warp.

[bertrenolds5]

Just an update, I said forget it. It was to risky and 8mm studs will probably work just as good. I probably won't ever have enough power to break them anyways.

When I had the head off my old Eclipse (6+ years ago) I had all the holes machined out to 10mm. I did the 2g manifold at the same time. That thing was fricken rock solid. I could have hung a semi turbo off that manifold. I've seen the 8mm bolts break with age only, not even making tons of power.

"I've seen the 8mm bolts break with age only, not even making tons of power."
Good to hear, I'm getting new steel studs so I should be fine then.
