EGT sensor

[Mark One]

Right

A guy came round today about a custom turbo manifold for my project

We've decided on a top mounted:evil:, central, equal length manifold in 316 stainless. The guy is an ex-prodrive TIG welder and i've seen some of his work and it's WOW

I mentioned an EGT (exhaust gas temperature) Boss and he seemed ok with sticking one on for free if I could find him a Boss. So a few questions with regards to EGT sensors

• The boss - what size is it? is that universal throughout all sensors?
• Best place to buy a sensor? Best to buy a kit or what?
• How much am I looking at?
• Emerald has in input for a VAG G235 EGT interface, how much are these and is it worth putting the EGT into the emerald? Would it be better just to use a gauge on the dash? I spose emerald could Log the EGTs if it had an input.

Mine came with a boss you can screw in to the manifold. 1/4 bsp I believe. could be welded in once screwed in too I guess.

Are the thermocouples all likely to be 1/8NPT? I've found a few that are.

TBH, buy the one you want to use and have it done to suit. I think they'll near enough all be the same though

Lol. I'll see if the funds will stretch to that yet
selling the 172 shortly so that should help

Edit: if anyone knows anything about the VAG G235 sensors, please post
