Adding Emap sensor to 3SGTE egr port

Hi I'm currently building a 3sgte engine as was looking at how the Egr port is routed through the head and it got me thinking how easy it would be to add an emap sensor?

The egr port is drilled through the side of the 4th exhaust port and is blanked where it changes direction up to the egr valve. Would it be as simple as swapping the plug for a sensor? I'm thinking the head itself will extract heat to protect the sensor. I could also add copper tube off this port and remote mount the sensor if required.

Hi. It's not just a sensor it's a whole kit to be installed if you want to do it properly.

I'm not looking to use the data for tuning, it's purely reference. From what I've looked into it the "damper canisters" that are sold are just a shock absorber to average out the pulses to give a cleaner signal. To a certain extent a coiled pipe does the same job. That's what we use on pressure switches in large plumbing systems. The more coils the more volume and the more shock absorption.

I'm just making sure there's no particular reason I couldn't take off this port instead of having to drill/tap the turbo or manifold

You can certainly do it bearing in mind that exhaust gases temperature will be higher at that point since it's closer to combustion chamber and there is going to be no canister - it's not only used for pulsation smoothing but for heat tranfer too.

Thanks for the input. The port is right next to the coolant outlet so with the combination of that and the pipework. In happy the heat shouldn't be an issue

Exhaust gases velocity is so high they don't have enough time to cool down from head surface. That's why we use long length runners on exhaust manifolds before turbo. I'm not sure how long your pressure sensor is going to last facing high exhaust temperature on regular basis.

I just checked specs of AEM 5 Bar pressure sensor that I bought along with my EMAP kit and it turns out that its maximum operating temperature is 105 C only. I'm not sure that introducing it to 500-600-700 C temperature on regular basis is a good idea as I've seen tons of bursted OEM pressure sensors that don't get to see such harsh working environment but still break...

I do understand your concern so appreciate just sticking the sensor on that port probably isn't a good idea. What I'm thinking of do is coming of that port with either copper or aluminium tube and adding a number of turns to dissipate any heat and have the sensor at the other end of the tube.

There won't be a direct flow of exhaust gas past the sensor as it'll all be going through the turbo. (The egr in the engine isn't actually connected back to the intake as it's a JDM head but they still drilled and capped this port off).

The only way to find out for certain is to give it a try. If it doesn't work I'll cap the port back off and call it a day.
