Right then, update time!

Subject: EGT Sensor

The exhaust manifold started life like this:



20 minutes later:





Concerns:

The EGT sensor is shrouded by the adapter and the adapter itself only barely makes it into the mani:

Sensor in adapter



Adapter in mani:



So yeah, didn't even realise about that problem, thought the temperature probe would stick out way more than it did. And I went for the middle of the mani because 1. it's the middle and I like even things; and 2. it was nice and thick which gives the adapter threads a lot of material to grip into and therefore it won't leak.

Oh yeah and although you are supposed to use a 10.5mm drill bit for an M12 thread I got away with using a 10mm it was harder to turn the tap but the threads went in a treat and the adapter threads in and tightens nicely.

But yeah, couldn't find a 1/8th NPT tap for love nor money so from searching the XUD section I found MattCheese31 asked the same question and someone suggested this adapter which was what I went for.

Assuming I get away with the EGT sensor, the next little bit I need to tackle is the wastegate bracket, which I have no idea how to do other than get an off cut of steel welded to the comp housing and then get the wastegate actuator welded to that, which I can't do until I can get the exhaust housing elbow adapter faceplate (let's call it that) welded onto the exhaust housing which I can't get done until the welding guy comes back next week!
