I heard that removing the egr provides power gains. Someone please explain why and the simple task of removing it.

Thanks

 

you will get a CEL and get shitty gas mileage. A working EGR Is suposed to close off under hard throttle anywayz. So it wouldnt effect WOT . It reroutes exhaust that is not completely burned back thru the intake manifold under part throttle and idle to save gas. Hope that helps some

 

Thanks Pullig. I hate it when a car comes into the shop for a CEL and some weekend warrior has torn off half his EGR and thrown it in the trash, then gets pissed when you tell them they need $100+ in new parts.

Depends wether or not you care to be smog legal. I run a P28 Ecu and blocked the EGR port in the head to avoid excessive intake manifold temps. This will effect whp very little.

why would gas mileage go down? please explain

 

because it want be recirculating the unburned gas in the exhaust . EGR means Exhaust Gas recirculation. So which means if it dont recirculate the ecu has to inject more fuel. You understand

LOL Do you eat your own ****? Hope, not... EGR is only for ecology BS. Exhaust gases lower the temperature while combustion thus lower NO level (which helps to avoid acid rains).
Find out about EGR more.

I know what ******* EGR stands for, thanks. I don't think you know what you're talking about.

Thas why people want to block it off cuz u dont eat your own **** . But the thing is a properly operating EGR blocks it off and dont recirculate under hard throttle. You know that there is unburned fuel left in the exhaust it jsut recirculates that back into the manifold and it takes less fuel that the injectors have to inject to get Stoich

That's not true, the EGR gases are considered inert and do not contribute to combustion.

 

exactly

 

so what would be the benefit of blocking it off? I have a swapped civic (no EGR) and I have been running around with code 12 for like a year and a half. I was under the impression that it had no effect on performance.

I don't see any benefit of blocking off the EGR port on the manifold however I do see a benfit of plugging the actual exhaust port in the head so the hot exhaust is not circulating in the intake manifold.

 

There is no benefit of blocking it on a modern vehicle, and it could in fact lead to part throttle detonation.

 

*n00b alert*

how would I go about doing this? (blocking the exhaust port) my motor always pulls harder in the first 15-20 minutes of driving, so I think my int. mani. might be getting hot.

Pull the manifold and buy a 5/8 tap and bolt. Once the port is tapped screw the bolt in until it's tight then cut the head of the bolt off with a dremel or similar device. I'm sure there are other plugs available but I was too lazy to go anywhere else besides Home Depot. Make sure you use a hondata intake manifold gasket also.

 

thanks! hopefully I will be able to pull the manifold without too much trouble. It sits like an inch or so away from the firewall.

 

i got an extra intake manifold if you dont want to **** up the only one you have. Also have an extra EGR.

Yeah mine is tight too. I don't even know if I can take the mani off with the head on the motor (Integra chassis).

well if you can't then I probably can't, since our chassis (95 civic) are pretty much the same.

 

I have a proportioning valve from a civic right behind the mani therefore it's a tight squeeze... My mani actually touchs the proportioning valve.

Maybe you can take the top of the manifold and T-Body off first to get a little extra room?
