Guys Running NO EGR valve

This is for a 1996. Im doing away with the EGR valve on the DEK im putting in. Im a bit unclear what Im suppose to do with the EGRC selenoid valve. Guys that are not running the EGR valve, what did you do with that. Plus, the EGR temp sensor, is that a really sensative sensor or can I just zip tie it close to the exhaust manifold?

Theres a vaccum line running to the bottom of the TB. You guys connect a line there, or since your not using EGR, you dont have to, right ?

Any feedback would be swell

i just did away with any EGR, and left all egr sensors unplugged. Car runs fine.

if you don't want a code just leave the egr sensor plugged in.

Where did you route all the vaccum lines ?? How about the vaccum line running to the lower part of the TB ??

Everytime I have bypassed my EGR the light comes on. Sometimes it take weeks, months, or days to show up.

I had the temp sensor and solenoid hooked up, but capped off the port on the solenoid to the back pressure transducer.

I ran without EGR for over a year without a code. I left the solenoid and temp sensor plugged in, and the vacuum lines plugged in as well. (I think)

I am putting a 2000 in my 95 and am taking the egr off. what are the negatives..overheating? I will be driving my car back and forth to school a couple times a year and those are atleast 8 hour trips..what does taking the egr out effect? overheating temps?..combustion temps..?

It does not affect the coolant system that much. It shouldn't overheat. Bypassing the TB and the IM EGR port will make the IM much cooler however.

It affects the combustion temps at low load. It will not make your car any less reliable.

Guys running EGR, you really see a "Significant" loss of MPG ??
Do you still have vaccum going to the bottom of the Throttle Body ??

I'm curious about this as well since I'm opting not to keep it hooked up when I do my 00VI install.

Do you mean not running EGR will show significant loss of MPG?

That's what he's asking, and I think the answer is no. I don't think EGR has that big of an influence. As stated above, it's probably like 0.5 MPG.

are combustion temps dangerous..since they will be higher with out egr?

One could deduce that temps are not dangerous as nobody has had a problem once removing the system.

Plug the manifold hole. Plug the IM port. Do away with all the TB and IM coolant lines. Plug all remaining vacum lines except for FPR line and possible BOV. I run like that with no ill effects. Cold startup was a bit worse for me. Now its a **** for me because I run no IACV but thats a different issue. Removing all this really unclutters that area and makes all future work in that area super easy.

Well Broaner, your use of the VQ30 is a little different then the factory application. Removing emissions entirely isnt for every one. Plus they dont really take away HP, just add clutter so if its your DD theres no reason to remove them.

However I just got my VQ30 for my 90 s13, HB. It'll be a track **** too so no emissions, just megasquirt'd simplicity. buhahahaha.

Since I don't need to pass emissions where I live it's not really a problem for me, and as long as there aren't going to be any ill effects (temps, gas mileage, etc.) then I'd rather remove it and remove some clutter than pay for a bunch of stuff to keep it with my new manifold.

Well if you dont need to worry about passing emmisions test, then you can definetly take it out. There are no ill effects to having it out. I cant wait to keep a nice clean intake manifold and components

true matty, an oil catch can on the PCV helps from getting the other crud in there.

Haha. Chalk up another S chassis to the beastliness of the VQ. This swap is spreading like wild fire. Good luck.

So if i did away with egr and evap, the fpr is the only thing that needs vaccum, besides the brake booster?

i have ripped out everything hoses ,solenoids ,wires all gone . i did leave the temp sensor.

that bunch of metal hoses grouped together i ripped that whole thing out and rerouted fuel and the other things with all new lines.

i also have a egr resister dont know what size 98seblackmax put it in for me .

another key is a have switched to a 95 fed ecu ,and since then have gotten 0 egr codes.my car is code free from the 3.5 swap ans i have taken every emissions thing off. i have no evap system its 100% gone . i took that boost junk off to.

i have removed like i said 100% of emissions and my car gets hooked once a year to DMV computers . i have 0 codes and 0 not readys

i disagree about removing them do you know how much all that stuff will cost when it goes bad?! one solenoid is around $100. evap egr all that stuff will go bad eventually and my stuff was throwing codes for no reason so i ditched it all . it also saved alot of weight which helps gas milage . my car gets over 30 mpg on the highway and runs decent at the track

so only thing you have hooked up is the temp sensor and FPR vaccum?

Also, what is the purpose of that resister?

Bingo. Some of us don't even need brake booster.

I've had my EGR blocked off since I did the swap (been about 4 months now) and did definitely notice a hurt in my gas mileage. Granted, it's a bad time to compare due to winter gas and all the other conditions associated with winter that waste more gas, but, I took a bigger hit than I did the previous winter. With my driving style (a little aggressive, but not ridiculous) I was down close to 16 MPG at some points So I'm definitely hooking my EGR back up. Luckily mine was never removed, I simply put block-off plates on the manifold and EGR valve.

I've never gotten an EGR code in the last almost 2yrs since I've done my swap. Actually the VI swap improved my gas mileage a bit... once I got over the initial new found joys of WOT pulls to redline
