I'm going to purchase an exhaust temp gauge, but before i do i wanted to know if the sensor is fitted into a factory position or if i have to modify anything to fit it up.

Any help on the matter would be great.

Thanks,

Russ.

youll need a workshop to drill a bung into the exhaust dump pipe, much like the 02 sensor

theres no factory hole for an EGT, theres one on the CAT but if you are getting a guage i would expect you would want it off the dump pipe

no no. the a egt guage has to be before the turbo. usually in the exhaust housing or rite at its entry.

or if your hard core you have one for each port just at the port exit. having it after the turbo is pointless. may as well have it on the muffler.

In an ideal world right at the exhaust ports is best, followed by at the turbo inlet but normally room is a bit of an issue.

If you are only running one EGT sensor putting it in the dump pipe right after the turbo is fine. Just remember if you are using it to set up fuel via EGT you need to allow for the loss of temp through the turbo.

Been running that way on diesels for years as a guide as to when to back off the throttle.

99.9% of EGT sensors ive ever seen fitted have been in the dump pipe. the one example of not was on an FJ20 were there was one on every exhaust port.

how much heat would be lost between the exhaust port and the dump? most people i know run them after the turbo as more of a just in case rather than for their tuning properties.

i had fitted mine into the stock cat location while i waited to fit up my dump pipe and i read heaps lower than expected.

Does anyone know if the sensors 'loom' will reach from the dump to the a pillar where the gauge will be mounted ?

I'm going to get the Blitz BLM egt gauge to match the rest of my gauges.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
