Shun! Shun the non-believer!!!

Just to confirm, 850-860°C with the probe after the turbo?

Correct.

Correct.

Its a Ford engine in a Peugeot, in some peoples eyes possibly the worst combination ever, if it was a I5 I'd still probably be slated

I'll put a I5 in something, it will happen, probably best I finish this car first

I know people that have had them fail due to probably ALS use, luckily they were situated in the downpipe not the manifold. They were not cheap probes either but that depends what you class as cheap ?

Certainly interesting info, just not sure I'd fancy keeping one before the turbo for any length of time but as you say you you don't use ALS that could well be why you haven't had a problem.

Mine is situated in the elbow that connects the manifold to the turbo, its used when the engine goes on the dyno but I have decided to keep one fitted at all times but chose the downpipe just to be on the safe side !

yes, that is what i said, i dont use ALS. if i did i would probably not take any chances, and get the sensor placed in the downpipe. But all im saying is that if you dont use ALS it should be fine.

I used an M12x1.5 bolt from the stealer (front brake caliper carrier to strut bolt) drill+tapped halfway to suit the compression fitting for my probe and used the redundant tapped hole in the downpipe just after the turbo.

Right, I need to get a lambda to 1/4" NPT adaptor but can't readily find one... Suggestions please

[Jonas_R]

Not sure why you need the adaptor but you could just buy a 1/8" npt bung and then weld it inside the lambda bung.

I did that on my own car

Get an M18 bolt and drill and tap it 1/4" NPT.

[Jonas_R]

Get a lambda plug with a very low head thickness like this one. Head thickness is around 2-3mm this way your egt probe won't sit to far up

Then tap and drill appropriate thread

For simplicity, I had a lambda bung welded in to my DP, so I can fit a WB if I need to and am going to fit the EGT probe there. Anyone able to drill and tap a plug for me, save buying a tap etc. Cheers

[Jonas_R]

I think we have 1/4" npt tap at work but shipping cost is a concern I guess.

[Rusty]

Thanks for the offer but as you say, shipping might cost. Much appreciated.

[AndyP]

I'm sure I have a tap, if I can find it I'll see if I can knock something together this weekend

[AndyP]

Sorry but it's a 1/8 NPT tap I have, not 1/4

I'd buy this:-

and take it to a local engineering company and see if they will drill and tap it.
