EGR and PTU Questions

[epickakashi]

hey does anyone know if its possible to remove the egr with just the plenum removed and if i wanted to relocate the ptu where would i relocate it to.

[nghtrain88]

qestion?? lol someone correct me if I'm wrong, but yes I believe you can install a block off plate on the EGR tubing with just the plenum removed

[MiiLaNo]

yea I think you can, you just cant remove without having the engine or transmission pulled I believe

[nsrZ32]

Yes you can block it off with the intake plenum off.

And I would recommend relocating the PTU to under the nose panel

thats a good idea nsr... ill be relocating my ptu this weekend.

it's fairly easy to relocate the ptu to under the drivers side headlight.

I deleted the EGR last year, and to fully remove all of it, you need to pull the engine or transmission as I did. As the others said, you could block off the plenum ports, but you somehow have to remove the tubes as they protrude up into the plenum a bit. This might be a real challenge as they travel under the plenum to the EGR and you can't get to the fittings to disconnect them without the transmission out. To be safe, I'd want to block off the exhaust feed port so you don't risk and hot and potentially lethal gasses from being expelled into the engine compartment.If the EGR still works, I'd leave it alone until you are at an opportune time to properly remove it.As NSR says, relocate the ptu to the nose. It's fairly easy to do, but much easier if your radiator is out so you can run the harness into that area as there is some room on the upper driver's side even with the A/C condenser in place.

Mine is under the nose panel too!

is it possible to remove the whole egr setup on a NA motor with just the plenum removed and also i was wondering what is the reflective stuff under the hood of alot of Zs and where can i get some?

thanks for the help.

[GAZ32]

You can polish it since its aluminum. I think Jerry did that?

[YCDEVIL]

wheres the 350z ptu located?

[evildky]

I am pretty sure the Z33 does not use a PTU, I believe they are fired directly from the ECU

[demonyoka420]

Yeah you can remove the EGR with the plenum off, just got done doing it a couple weeks ago actually. But it was definetly a big pita to do.

Also when relocating the PTU to under the nose panel how do you mount it there? And are there any benefits other than cleaning things up a bit? Pics of this would be awesome

[OUKNO]

PTU under the nose? I get the idea but?Jerry you recommended this to me...pics would be cool or some sort of a tutorial

It is damn near impossible to take out the ENTIRE EGR system. But you can get most of it disabled. Fully removal needs to be done when engine is out.

To eliminate it the half *** way is to simply remove the plenum. Cut the egr tubing in the middle, the one that runs the length of the exhaust manifold and close them up. I've done this many time and normally recommend pinching the tube closed and then use JB weld to close it up. You will need to block off the now open area under the plenum. Disconnect the vacuum line that leads to the EGR in the rear. You can now eliminate the EGR solenoid at this time as well.

If you even pull the engine you will then need to pull off the rest of the EGR system in back of the engine. 2 12mm bolts and you will need to remove a feeder tube that goes from the EGR to the manifold. It is around the diameter of a quarter.

After that, the whole system is gone.

Definetly a b1tch but it can be done with just the plenum off, I actually had to cut one of my wrenches to make it short enough to fit in a certain area to get a part of it off. But all in all we removed the entire thing with the engine in the car. Actually i posted some pics up of custom design wrench we needed to get the thang out.

[Honad]

With the engine out, it's like a 10 minute job.

With it in, yes, with just the plenum off you can effectively delete the EGR, however, I don't believe you can actually get all then unecessary crap out.

[OUKNO]

If you have really small arms LOL the EGR can come out with engine in and plennum off it has been done GOOD LUCK!!!

Ok now thats said the PTU relocation come on some one give me an answer how to do this. Do I just unscrew it and put it where ever I want?Is there a need to lengthen the wires if going in the nose of the Z?

[mike58177]

where is the PTU in a 1990 nissan 300zx non turbo ?????

[michaell32]

II deleted the entire egr system with the engine and transmission in. I pulled the plenum to change the injectors and decided to delete the egr. It was a pain in the a** and took over 3 hours. I dont recommend anyone to do it like that. At least pull the transmission if you take it that far.

[Zwicked]

This is how I relocated the PTU, and eliminated the subharness.

[NicoET]

yes you can remove it. It is kind of a pain, especially if it has never been off because those bolts are a biatch to get to.

Revival of dead post. I just recently completed an egr delete without pulling the motor or transmission or brake booster. It wasn't easy though. After cutting all the pipes and removing everything except the exhaust feed line nut I used two 1/2 drive extensions, ratchet and pivot head extension and 22mm socket and a breaker bar pipe. Plus the nut was soaked for 2 days with PB blaster. I also had to wedge a long screwdriver under the bottom of the socket to prevent it from twisting off. But I accomplished it and i'm happy. I had to use a cable extension for my dremel to get deep enough to reach the exhaust feed line nut.
