should i put it in the manifold itself or in the stock DSM o2 housing?

 

i could eb wrong, but i beleave i read that they should be as close to the O2 sensor as they can be.

 

3rd runner on the manifold.

 

I'll second the 3rd runner.

If you get a dual EGT gauge, you can always stick a second one in the collector right before the turbo to compare hottest and average EGT. If you stick it after the turbo in the downpipe, you read a max of around 800 degrees F when in boost... pressure-enthalpy conversion leeches a lot of the heat/energy out of the exhaust gas.

 

3rd runner is best.

Mine is after the turbo on the downpipe and it reads allot colder than one on the runner. I am usually at about 900 cruising. I have hit 1300 before.

mine was intall in the o2 sensor hole on the std manifold. And i read 1450,1500
F at 60mph. So it hot. Do you think it will be better on the 3 runner??

 

i put mines on the #1 cylinder runner is this not good?

 

On Honda motors it is better to have them on the #3 cylinder. The #3 cylinder has been known to be the first one to go out because of high heat levels. This would make the #3 the ideal position to place the probe since you could see what the hottest part of the motor is. The #1 runner would be fine, but it is not the best spot. I don't think it would be anything to worry about.

ok some person told me to put the EGT after the turbo when we are FI and in the manifold when we are N/A.

 

you can but your temps will be cooler, wouldn't you rather know your hottest temp? i think that is safer, you can also put it 1 inch from your muffler if you want
