Ah yes, Autoshop 101. Because I have even better info I keep forgetting about it. What's really unbelievable is that resource has been repeatably mentioned here yet people refuse to read it. If they only would I could move on. That ought to be motivation enough for many ;)

exactly. What you guys have to realize is that even though you are passing your knowledge around in various threads on SM, we the members cant be in every thread posted. You could have very well posted this info in another thread on a topic that started out with nothing to do with EGR but turned into an informative thread about it. It happens everyday. I wish I had time to sit down and read every thread in here but I dont. None the less I appreciate the knowledge you guys share, again.

I do realize it. However in this case, EGR removal has been an "issue" since I went to internet Supra message boards. And after repeating the same stuff for a few years, it gets old.

Especially in the same forum.

I agree about not reading every post. I don't do it either.

Is there any recorded data or undisputable evidence available in support of keeping the egr system on the mk3 supra
I thought I just gave you some. The factory manual.
Ah yes the toyota factory manual , the same manual that states 58ft/lbs for the headbolt torque

Btw, I don't understand how anyone would "know" they aren't having detonation issues unless they were monitoring knock. That said the knock control system remains active if EGR is removed and when higher octane is used with a good tune removal shouldn't be an issue.
So now your saying that running without egr may NOT rip your engine to bits ??????

As far as emission and saving the planet go , what use is a system that draws off the environmentally harmful gases off one cylinder and lets the crap from the remaining 5 cylinders belch out into the atmosphere?
You must be joking. For someone who has researched EGR thoroughly you seem to have a poor understanding of how it operates and what it does.

Simple ....a small amount exhaust gas with a minute quantity of combustion cooling Co2 gas is drawn from ONLY number 6 exhaust port.
Is this minute quantity of Co2 enough to cool combustion when divided amongst the 6 cylinders ? ....the majority of gases from from the other exhaust ports drive the hot side of the turbo and exit ( via cats in certain countries) through the tail pipe , even with cats fitted your still not pumping out ice cream into the atmosphere


Besides, would anyone driving a 3 litre turbocharged car be justified in taking any stand on the green house gas issue?
You appear to be confused about emissions. What does turbocharging have to do with the greenhouse gas issue?

I was taking the piss after you appeared to be preaching off the environmental soapbox .....you do drive a mk3 dont you ,its hardly a planet saving type of car is it ??

Jetjock/Nick i hear what your saying .

What i,m disputing here is the effectiveness of the mk3 supras egr system , not EGR in principle.

Lets see some examples ( not one but a few ) of datalogged difference in EGT,s with and without the EGR system fitted on a MK3 supra.........Then and only then will there be an informed choice about egr removal.

Lol. Good one ;)

Dr Evil: I wasn't referring to the service manual. I was referring to internal Toyota engineering and service training information. You know, stuff from the engineers who designed the car and programmed the computer, written for professional technicians who understand how cars work.

You still have EGR wrong but I've learned one can't argue with a drunken man. Disputing it's effectiveness? Not pumping ice cream? Bollocks. In California it's ice cream enough to satisfy the strictest emissions standards on the planet so from that statement it appears you wouldn't know clean from dirty emissions if they bit you on the arse. As for EGT increase sans EGR there are several here who've seen it and rightly so. Why wouldn't they? It's basic combustion theory. That aside you admit EGR has a cooling effect on combustion yet refuse to believe without it EGT won't increase? Ahhh...

You make it sound as if the 7M is rocket science, somehow different from other petrol engines. As if the same principles that have been around for 100 years and are well understood don't apply. That alone makes you look ignorant. I'd suggest you spend $100 to join the SAE so you could educate yourself but somehow I get the idea you want to remain another guy who doesn't know what he doesn't know. That said it's your car, you can do as you wish with it. Cheers ;)

Dr Evil - I'm not going to be as nice as JJ...I've been watching this thread and came to the conclusion that you sir are a:




You have a basic understanding (at best) of how the EGR works in the 7M. Obviously did not read any of the references Nick provided. Then presented an emotional argument when presented with the facts...welcome to the list.

Then why are you driving this car if it is such a steaming pile? Maybe it should be Dr asshat.
