I am talking with Aaron from NWP Engineering about creating an EGR removal kit for the 4th gen. (This may also be compatible with the DEKs that have EGRs but Im not sure.) Aaron already makes a kit for 3rd gen VEs that goes for $35. The kit will consist of block plates, exhaust manifold plug, vacuum caps, and other various hardware. Im sure Aaron will include detailed instructions along with some stickers like he does with every other kit

Removing your EGR will most likely create a CEL or two but some have beaten that by tricking the sensors. Removing the EGR will create some more free room in the engine bay and be minor weight reduction, but mainly it will keep your upper intake manifold clean. (You know all that crap that clogs the IACV and gets in your throttle body, along with the rest of the engine) Keeping the engine cleaner will obviously keep it running smoother and will require less cleaning of various parts. Now keep in mind if you have emission testings this will cause poorer results. The whole point of the EGR is to reduce NOx emissions. Im not sure if it hurts it enough that you will fail but I dont think it does. This kit though will most likely cause a CEL so keep that in mind.

Anyways, this is just a poll to see if there is interest in a kit for Aaron's sake. Hopefully there is cause I would really like to see Aaron make a kit.

ps: dont say yes unless you would really buy one...I know alot of you like to say yes then back out when it comes to the $$

At the moment I have one good thing going for me. The readers that my state uses to check the code on the ECU will not read the JWT ECU. I end up having to do a pipe test which I always pass. Though that will change in Aug. Good thing emissions is every 2 years.

It shouldn't hurt idle emissions as the EGR only opens during crusing, and it shouldn't make that big of a difference. I had a bad EGR valve in my 2nd gen and was still able to pass a pipe test. However it might be a different story on a 4th gen.

Thanks for the info. Im going to look in the FSM tonight to see if the EGR sensors can be tricked with resistors. Aaron says they can be on the third gen so its possible on the 4th to if they arent too different.

I have just purchased a new guide tube with new bolts and nuts. I have the 0302 code. Would be nice to get rid of it all!!!!!

why in the world do people block off their EGR?!1?!~! (especially 00VI swappers?!)

EGR=good. The way it reduces NOx is by keeping combustion chamber temps down.
Blocking off EGR increases emissions AND your likelyness of pre-ignition AND throws a CEL.

Take a couple hours and clean your manifold and guide tube. Problem solved.

Because it cleans up the engine bay? Makes things easier to work on? Or, krismax style, weight savings?

FWIW, I completely removed my EGR system. Found out that the block off plate for a 3000GT fits the A32USDMIM () perfectly (found one laying around the shop, and it fits the gasket and port on the intake just like it was made for this car).

Thank you for your opinion and post (seriously). I want everyone to know both sides of what this mod does so people can make an intelligent decision for what they want.

However I would like to say that I have never heard of anyone with a removed EGR complain about pre-ignition or any other engine problems besides a CEL but I already mentioned that.

Well since there is already an option for the block off plate and Nissan sells the Manifold plug. I'm not sure if there is a need for a kit or people would buy it. Unless of course the resistors were included to be CEL free and great installation instructions

What block off plate is already available?

Some people might prefer an already put together kit instead of ordering from several different places and then not be sure if they have everything. I for one am interested cause I want a quality block off plate instead of the ghetto piece of metal I am using now on the UIM. Aaron is also looking into finding a cheaper manifold plug other than the Nissan one that is about $8. The resistors are also going to be looked into.

I'll agree, it's not common to have pre-ignition when blocking off the EGR, but it will increase your chances. 4th gens RARELY knock anyway, so it's probably not a concern. I just wanted people to know how and why EGR works and that it actually does do good things. (I used to think it was completely pointless!)

i would be down if the cel issue was taken care of and it all came in one kit. seems like it would compliment their spacer kit well.

didn't vote since its pending my conditions, but if they aremet i'll definitely buy it.

It seems as if that will be a the major deciding factor for many. If for sure this kit can block off EGR, and not trip a CEL, then I'm sure many would be for the kit.

I know for those in GA, ODB-II equipped vehicles do not perform emissions on the rollers, they do a gas cap test, and then scan the ECU for trouble codes. If there is even one code you automatically fail the emission test. No Cel automatically pass.

Um, guys, I dont know where the hell the CEL idea comes in...

I have been running with no EGR for 7 months now, and I have no CEL. As long as you leave the EGR temperature sensor plugged in, no CEL is tripped.

I have no egr (external at least, 3.5swap) and I left my sensor plugged in and sometimes I dont have a code, sometimes I do.

I'll pull codes tommorow and see if I'm throw a code for them.

+1 you can remove all those silly gallerys


i dont get one either and mine is just dangling there.

but i voted no cause likepmohr said there are alternitives to running no egr.

I have a good question!

One of the main reason to remove it, is to keep TB - IM clean, no?
Of course we have the magic cel light 0302 too (flow block).

So, why we cant just relocate the tube?
Block the hole near the tb and take a high temp hose to bring this near the air box but NOT directly in the air system, more easy when you have a short ram intake.
Then, it'll be easyer to clean, and the crap wont acces the intake mainfold so easly.


I can do a howto if theres no reason to dont do it.

Ahh its easy to clean when your motor is out. Its a PITA when the car is on though. Especially when it hasnt been cleaned in along time, all those heat cycles make those bolts a pain to get off sometimes.

If one were to pull off there coolant tubes/vacuum tree it would give you so much more room to work with, and its not overly difficult.

For those of you who do the egr cleaning, be very careful to torque the bolts to spec, i personally have stripped the bolts holding the egr guide tube to the manifold, and trust me, thats not something you want to have to try to re-tap while its in the car..
