Getting my pacemakers fitted tomorrow, considering not drilling the fitting for the EGR, more so for when the valve decides to stop working than any fully sick 2kw gains. If I just leave this undrilled on the extractor end and still fit the EGR pipe to it will this cause any issues? It would be much like just blanking it off as a few members have already done wouldn't it? Sorry if it doen't make an awful lot of sense, its a little hard to explain.
Thanks, Aaron.

No, it'll be fine if you leave it fitted, but but choose not to drill the EGR port on the extractors. It's also a good idea to disable the solenoid for the system: At the front of the intake manifold runners, there are two brown plugs. The left one is for the charcoal canister, the right is for EGR, which you can unplug to disable the system.

Thanks mate, thats one future problem sorted :D

If you don't connect the EGR be sure to block the EGR pipe/block the EGR valve otherwise the engine can pull air in and lean the mixture under load.

Cheers, Alan

Provided the pipe is correctly seated into the extractors you will not get any air being pulled so you can leave the system alone and simply not drill the hole. Not legal of course but will look legal when checked externally

You can if you choose place a very small ball bearing in the val line, I suggest it is done in a way not be be obvious externally as this is the first thing the authorities look for when doing EPA tests.

That's some quite useful information mate! Thanks for that, have been wanting a way around it for a while :)

Edit: Also to Madmagna for the ball bearing trick, will give these a shot when I get home.

cut mine off my pacemakers and linished it all up when we were designing the merge collector, also 'debadged' them.. had to on the front pipes anyway as we had to make new sections for the front (they were a crushed set i got for free)

EGR?? what EGR?? :redface:

EGR?? what EGR?? :redface:

Exhaust Gas Recirculation. The system injects a small amount of exhaust gas from the rear bank into the inlet plenum, which apparently promotes cooler combustion, and lower levels of nitrogen oxides.

wow.. sarcasm doesn't really portray too well through the forums... or maybe i'm just not the best person to demonstrate this..

i know what EGR is.. and i removed it on the first set of extractors i put on.. simply cut out a little ally plate, linished it all up and square and bolted it onto the plenum, the first set of extractors i had (xforce) didn't have any provision for EGR.. rather than make one in them, it was much easier to make a blanking plate :)

and with the pacemakers... when i was reparing/modifiing them i just cut that off the rear bank, and cleaned it all up.. ofcourse with a nice coat of paint now they look a million bucks..

just be aware that it is a huge fine if it is found that you actively removed an emissions mechanism on the engine.

Its only illegal if you get caught

exactly...

i am not worried in the slightest...

Heh, it's just me not reading properly lol

I've done a similar thing with my plenum - a plate to block the hole, and since my extractors didn't even have provision to accept the pipe, that was that.

I wouldn't have thought it would really matter as long as it still passes emissions testing? Oh well, at lest mine looks stock... :D

the law wont care a cent that it is still within emissions limits. There are strict laws around the emissions systems on modern cars and if you are caught out you may get stung. Just a warning from experience

Any power gained by doing this???

prob not much, as the system isnt on all the time. mabey when it is working, their might be some slight gains, as pumping exhaust in your intake you would think reduce power

Leaving it connected actually encourages slightly better fuel economy - although it's only ever active under light load.

On that subject, any reason why pre EGR models have a plate already made up for the intake plenum? i was just thinking about this and low and behold there is a relative thread on the matter. is it a case of mitsubishi not going forward with it by already meeting emmssions control? and using it as a back up? or is it to save money by producing an intake sutiable for both engines (3.0 3.5) with both being already developed and the 3.0 only being avaliable?

It's pretty much all those things. The 6G72 and 6G74 were used all over the world, so they'd just be modified to suit the emissions requirements of the country they were being used in. California, for example, has pretty stringent emissions laws, and that might necessitate using EGR to meet requirements for a particular model; whereas Japan might not be so strict.
