would it be okto install my prob in my #3 cylinder exhaust runner, pre turbo? if the car is running

 

That's where it is suppose to be.... about 1.5 to 2 inches from the exhaust flange in the runner.

 

can i install it onthe car while it is assembled

 

Are you asking if you can install it while it's running?

 

Yeah you can, but it'd be pretty dumb.

 

yeah, my friend did it on his diesel truck while it was running, i was just wondering if the small metal shavings that did fall into the exhaust if theyed flow threw the turbo

 

What I've done in the past is when drilling or tapping is to put some grease on the bit so the metal flakes stick to it instead of going in the manifold.

 

i would never run a egt probe per turbo what if it brakes off??? there goes your 1300 turbo

 

When was the last time you saw an EGT probe break? I work with TC and even RTD probes all the time and have yet to see one break. lol

I myself have 4 egt probes.... one for each cylinder.

 

An EGT probe break? I haven't thought twice about putting it in front of my GT30. I've never heard of an EGT breaking off.

I've drilled DSM mani's several times pre-turbo. Used grease on the bit and had the motor running...no problems ever.

 

I've seen them break off in Subarus before, as well as their pre-turbo cats.

 

It depends on your EGT. The above fellas state 1.5-2" away from the manifold flange. I have an AIM sports and it requires 6" distance from the flange, on cyl #1. What EGT do you have? Whatever it is, follow those directions.

 

That is dependant on the type of probe. Theirs might not be able to handle the stress....

 

Why are you guys drilling and tapping an EGT probe while the engine is running?

 

... I'm wondering the same thing

 

I think running = assembled....?

 

i think running = running so that the tiny shavings of metal can be expelled through the turbo gradually instead of a pile of them building up then getting slung all around when the motor gets started up.

 

I would think that since it is pre turbo, there is a bit of back pressure in the pipes...so when you punch through it pushes gases and metal shavings out of the hole instead of allowing them to fall in........I still dont get it though, we are talking about a honda right? It takes less than half an hour to pull the manifold off, and not risk ANY metal going through the turbo

 

1/2 an hr? hah! not in a DA with a topmount. = no room!

 

Of course personal preference is to remove the manifold. I certainly removed mine. Fact is though, it's very common practice in the DSM world. A lot of those guys run stock manifolds, yet do various mods (MAF hack, boost controller, afc, etc) and adding an EGT is something they'd like to do, but don't want to deal with galled bolts.

Therefore, yes, with the motor running, drill the port with some grease on the drill bit. Between the grease grabbing shavings and exhaust pushing them out it's pretty safe. Would I do it on DSM's with 14b's..yes, and I have...would I do it with my GT3082r downwind..hell no. The risk is low, but when CHRA's are 1000 bucks low risk isn't low enough.

 

^ thats my point, I can see on a diesel or something similar, but cmon....even if it is a topmount, its still a honda.....
