Egt Setup

[tuned_nismo]

hi i was installing my new exhaust and saw theres a factory egt probe in the cat i was wondering when my egt gauge arrives if i can just tap right into that sensor, instead of drilling before the turbo i wanna tap into the factory one and monitor the whole exhaust system

[r33canada]

i would also like to know this

[lachlanw]

no . its too far away from engine to be any use

In theory yes you can do it, however the temperature readings will not be useful. I run mine in the dump pipe just after the exhaust housing.

the best way would be individually on each cyliner runner for the manifold, second best would be the where the manifold and turbo meet..anywhere else is pretty useless.

Isn't this a sensor for the ECU? You can't use it for your gauge?

Some turbine housings have a hex bolt in there that can be removed for the EGT probe to be installed. I have a defi EGT to install but I am waiting until I get the GT3076R in there.

Turbos definitely absorb heat from the exhaust gas so if you want to know the average EGT from the engine then the probe needs to be where all the gasses meet - generally the front of a single scroll turbine housing .

Cheers A .

Actually if you could afford to run two then just before the turbos mount flange in the std exhaust manifold could work if there is enough meat in the casting .

The one in the cat (oem) is just an overtemp indicator. Doesn't do anything other than bring on an idiot light. Not a sensor just a switch.

My egt sensor is fitted in the junction of the rear three cylinders on the exhaust manifold, before the turbo. Drill and tap.
