yes but in most cases it is not necessary

egt temps
 

I finally fitted the egt gauge. I mounted the probe/thermocouple just after the turbo and the wastegate in the elbow of the exhaust down pipe. I mounted it after the turbo because, I have read that if it were before the turbo, the probe might break and fall in the turbo causing damage. I went for a test drive and saw 300 deg Celsius. Can someone tell me what the egt's will be if I mounted the probe before the turbo. Thank you very much.

does it only read in celsius. it would be more helpful if it was in farenheit

Yes. That's the one I found.

How much should I be safe? I mounted the egt probe just after the turbo.

300* Celsius is ~572* Fahrenheit 90% of us with EGT probes put them in the exhaust manifold. you get a more acurate reading than after the turbo. i've heard people say that the temperature difference from the manifold EGT to downpipe EGT can vary from ~200* F to 600* F so that being said your real EGT could be from ~800* to ~1200* it's kind of a gamble. i'd plug the hole you just made and put it in yer exhaust manifold.

the probe usually doesnt brake.to tell you the truth of all maganzines, TV shows, and internet i have never heard or seen a EGT Probe break. but if i were you i would mount it in the Exuast manifold. but before you do it take off the manifold and then drill into it. if you dont amd drill it and you do a crappy job of cleaning up the metal shavings it will go into your turbo and kill it. that i have heard of. hope it works

Thanks for your inputs. I put it in the manifold before the turbo like you said, but I didn't get that much difference. After the turbo, the max I've seen was 350* Celsius and now before the turbo I saw a max of 450.

450* C ~ 842* F

I didn't even know they made a Lancer in 1990... :D


sounds like a good MPG car!
