Default can I get a 1/2" to 1/8" npt adapter?

At least, I think the begi EGR port is 1/2", maybe 1/4". Stephanie?

Basically I'm looking for an adapter which is 1/4" npt thead on the outside, 1/8" on the inside so I can screw in my greddy egt probe. Any ideas?

bingo. I found that but need it in steel, dog. Can anyone confirm the thread I need for the begi manifold? I really think the greddy EGT bung is 1/4", even though the manual says otherwise.

The EGT probe is probably 1/8NPT, all of them I've seen are. If you can't find the adapter you need, you could buy a plug to fit in the EGR and then tap it for the EGT probe.

1/2" to 1/8" I was looking for one when I was building a pressure tester for my gas line out to my garage. Couldn't find one. Ended up doing 1/2" to 1/4", then 1/4" to 1/8".

Stephanie just said that the EGT is 3/8 npt.

I should have a 1/2npt to 3/8npt. I need to look.

So a brass fitting installed into the log manifold won't melt? I had my manifold drilled for the 1/8" EGT probe but decided I don't want to chance putting a probe pre-turbo in case it comes apart and flies into the turbo-I was just going to plug with brass but now I'm looking for a 1/8" iron plug instead. ?

Brass has a higher melting point than exhaust gas can provide. The difference is within 200C I think.

if you can't find the plug adapter, just get a plug with no hole and drill and tap the bish.

I may just do that with the plug I have in th egr hole...the hotel is going to love the guy who takes the manifold and turbo off his car in the parking lot. I wonder if a vacuum would suck the metal shavings out through the little, freshly tapped hole? lol

Which cylinder is the hottest on a 99 motor with a coolant reroute? Hopefully none.
