3RZ EGR Delete

I have seen a few threads about the basic stuff like buying or making the plates and where to place them as well as the resistor to insert so you don't throw a code .

My question is , does anyone have a write up on what vacumn lines get deleted ?

What about the vsv ? Can that go as well ?

Thanks

 

Just out of curiosity, what would this benefit?

 

Clean up underhood vacumn mess.
Avoid having to replace a bad egr.
Stops Intake manifold for getting clogged with oily mess.
Better fuel mileage possibly

 

that sounds like a wonderful idea then!

 

All of the vac lines that are in your hand in the pic get deleted. All three that go to the top of the Throttle body get deleted. Anything that connects to the EGR body itself as well. Also, that little green cube under the intake manifold that the EGR vac lines lead to will also get deleted. I did this on my 3rz this summer. LMK what specific questions you have and I'll be glad to answer. I had a tough time finding some info on this. I have a shit load of the resistors too since I could only find a 100 pack of them on Amazon so if you need some of those I can send you some for free.

I have a few pics at the start of this thread I started that may or may not be helpful to you. I might have a couple more on my computer at home, i'll check it out later.

I've seen threads on this before. Most people say it's not worth it and actually causes worse gas mileage. @boostedka did you notice any difference in mileage/performance?

 

I can't say for sure how much the egr delete by itself helped out since I did it the same time as a new fuel filter, injectors, and TB coolant delete. But I definitely noticed a difference in low end power and fuel mileage. Probably about 1-2 mpg.

 

Boosted , could you send me a resistor ?

That would be awesome .

Also how did you delete IAC valve ?

Thanks again

 

Yeah no problem. Just pm me you address and I'll send you a few on Monday.

I didn't delete the IAC. I relocated the tube it feeds from when I did the IC piping. I deleted the coolant lines that ran to the throttle body.

 

Do you still want a couple of those resistors? I didn;'t ever receive your address to mail them to you

 

So, you deleted the EGR system, and put a 10k ohm resistor in place of it. I was under the impression that the ecu looked for a change in reading at the o2 sensor when the EGR was active? Do you get any codes at all ?

 

Sent you a PM

 

I got a code before I put the resistor in. Since I put the resistor in tho I haven't gotten it since. It's been about 5 months now

 

Interesting...

 

Bumping old thread.

I’m in the process of doing this and got the genius idea to snip the wires off of the sensor. Then unplug them and solder them at my work bench. Problem is none of my solder will stick to these wires. They’re stainless or something. So I swung by my local hobby shop to see what he could do and he’s closed for the week. FML. I can solder almost anything except these wires.

Are the harness wires copper or more of this material?

 

The engine harness is copper, the temp probe wires are the only stainless ones on the engine. I just depinned the plug so I could solder the resistor to the pins

 

Okay so everything was a success except for the CEL. I just bent the 10k 1/4 watt resistor like a staple and inserted it into the plug and electrical taped it. 40 or so miles in and the light came back on. Tried replacing the resistor with another (10k 1/4 watt). Light still came back on after 40 or so miles. OBD2 throws EGR code. Is the difference just me not soldering it. I didn’t want to solder it if I didn’t have to in case I have to ever take it out.

Thanks

 

I didn’t solder mine when I did it. I just stuck it in and taped it up. How long are you leaving the ends that go into the plug? I made sure the went all the way to the bs k if the plug. As long as they’re contacting the metal inside the plug it should work.

 

I didn’t trim the ends the first time. Stuck it in as far as I could and the ends naturally bent down and I pressed it against the plug and taped it. The second time I bent the ends halfway to double them up to try to have more contact inside the plug.

 

Did you trim the resistor you used in the plug?
