Greeting from a Norwegian 200sx!
Wondering about the ERG valve on the S14 and the reason I
should not rip the sucker out?
Found out what to remove with SEARCH but no info about the question below:
Will it affect the normal operation of the standard ECU in any way or is it purly
a stand-alone emmision reduction system?
Thanks for teaching us frosty Vikings a thing or two about our cars!

There was a thread a few months ago saying that the EGR system helped to avoid detting.
Otherwise, the general opinion has been that it is safe to disable the EGR system by blocking its pipes .
I've left all my pipes in place for now, but i took off the vaccuum pipe from the top of the EGR thingy and blocked it with a bolt
So just to check. Blocking of this one that goes to the intake plenum: (Abit unsure if the term is vacuume side)
Thanks!
I must have missed the bit on it helping to avoid detting, and i`m not sure on the theory behind it, i can see how introducing warmed air into the intake system will reduce emissions, but surely as detenation is caused by high charge temp, the EGR will only increase the risk of detenation when it`s in use.
The only reason i know of it`s inclusion is to reduce emissions, it stops being as effective on high mileage engines as well, both reasons i think that the S14a had the EGR removed and a second cat was put in place.
I would be removing mine post haste were it not for the fact i`m fitting a 14A engine and therefore there is nothing to remove.

Just as a confimation to my earlier post with the picture.
Block where it says in illustration (ie. before the EGRC-BPT valve)
or between the EGRC-BPT and the EGR valve?
Hope it is before the EGRC-BPT
EGR bungs a bit of burned CO... something or other back into the intake, this is what prevents detting... also reduces power
saw the fecker in half and block it up.
im in the same position and after blocking mine up, but did i miss confermation reg the picture?
The place that is marked on the picture is one way to block it and
probably the easiest. The exhaust side hose is much bigger and
could be more of a headace to plug.
I will however remove the whole sucker which includes
"blocking" of the exhause manifold side, as my new manifold
does not have any connection for it.
The whole ide is really insane.. First I have a new huge intercooler
feeding nice and cool air to the intakemanifold then the EGR valve
feeds hot air straight from the manifold..It's defo
going in the wastebin.

Greetings from a Scottish 200sx!
If you have a standard manifold, how can you block the egr part?
If you block the part going from the valve to the intake manifold
you will disable the ERG so it's not really needed to think about
the exhaust manifold side.
If you want to I guess you could make yourself a bung of some
sort, but won't worry about it before you change manifold to
Bren's "bling" manifold. wont be an outlet for it.
I just sawed the pipe in half when I changed the manifold, welded a washer into the bung at the manifold and clamped the other end shut with mole grips...
What do you use to to block the EGR tub? HB pencil ala Bren Device? A couple of screws in the tubing? Also, do you cut the tubing in half and jam one of the above in it or?
i had my car running 12/13psi erg stuck open , ran lean n hot n burns up pistons rings etc
thanks to sxoc i found another engine should have her back weekend its been off road more then a month!!!!!!!!
greetings from ireland pete
After reading you post and some other info on the web, I agreeOriginally posted by david_connoll

that it's worth thinking twice about removing the ERG on a
standard engine. It can have unfourtunate effects like David here
explains..
Getting to the point where the E-manager or Power FC needs to
be installed so I belive the lean issue will be sorter out. if not, I
let you know here in another post.

if u remove it it cant stick open
So what do you block it with?
I am removing the whole EGR system, has the exhaust side plugged like this
and having a plate made up for the inlet side

Cud this problem be to do with the EGR?
