EGR Delete

[chuck0960]

So i deleted my EGR with the delete kit from Driftmotion. But now i dont know what to do with the vacuum lines that went from it to the hard metal lines under the intake.?. And also what to do with the (I think its a VSV valve or something) that was in the EGR line as well. Any help would be appreciated. Thanks

vacuum plugs man. vsv valve im not so sure on. u might get hassled a bit for egr delete, but in my experience, everytime i deleted the egr system (on my 84 crx, 93 altima, 84-89-91-91 camaro's, 87 toyota pickup etc...) i gained mileage and power. biggest gain was the altima. went from 26 mpg to 30 mpg, then up to 34 after i installed a CAI, header, exhaust and jim wolf ecu tune.

anyway, vacuum plugs are dirt cheap at any chain auto store, for an assorted pack its like 2-3 bucks.

Hilux is right, prepare for a little hassling, especially if you run a stock usdm computer.
Anyway, you can re route the vac lines to eliminate the egr line entirely for a clean look and you can either leave the vsv or just remove it as it is useless without the egr system. My "jdm" engine came with the egr blocked off already, I never installed one and havnt had any problems with it. I am not sure what computer I have though.
Did you take care of the over heating issue? What was the problem? FYI, a properly functioning EGR sytem will reduce combustion temps, that is what they do.

I thought i took care of the overheating problem but the other day it came back. Im running out of things besides tearing the motor apart again. I looked around for a hydrocarbon tester but nobody in my area sells them. Im to the point I just want to find a shop to motor swap a 1jz in it and get it over with, since thats what a lot of people do anyways.

That sucks. Just make sure you've checked everything before tearing it apart again. I mean everything, fan clutch, radiator, all those stupid little coolant hoses everywhere, tighten all hose clamps again, pressure test it and everything. The little stupid things are surprising sometimes with the ammount of trouble they can cause.
You can take some coolant out of your radiator or reservior, put it in a jar and bring it to a shop that has a gas analyzer (aka sniffer) diesel shops and emission testing shops should have them. Shake up the jar to release any trapped gasses and have them stick a "sniffer" in the jar to check for H/C's. You dont want to buy one, they're expensive. Good luck man, I hope it doesn't resort to the swap cuz thats just more down time.
Also, a bad coolant hose may not always leak coolant but can still suck in air during cool down periods, resulting in air pockets in the cooling system. Just a couple suggestions before going into teardown mode....again.

Oh, here we go... Ok, my turn...

There should be zero difference in power (except when you're pulling into a parking space so who the hell cares?). The MKIII's EGR isn't even active at 70+% throttle (the only time you ever worry about making power).

Your mileage should NEVER increase from deleting an EGR system as half the affect is due to the system effectively REDUCING the engine displacement (see: Honda for how to achieve crazy high MPG)... the second half (and more important) is that it cools the combustion chambers. If your mileage actually increases then you didn't delete a functional EGR you just amputated a leg which only had a broken ankle.

EGR REDUCES combustion chamber heat, the concern about it increasing heat is just that the cooler is near cylinder 6 and there isn't additional coolant flow to that specific cylinder.


: rant2:


And one more thing... a "performance K&N CAI" consisting of nothing other than a crap air filter sitting in your engine bay is NOT a CAI nor is it gaining you power.... more often than not it costs you power. The stock air box is the better setup of the two.

I'll stop with the peeves and let the backyard boys have the thread back. I'm soooooooo done with this site.
