Re: The vacuum hose reduction: walkthrough and pics
Just wondering (I have not read thru this in detail or thought about it carefully) . . . does this reduction make it easier to lift the intake plenum, like when changing sparkplugs etc. . . . or is most of the restriction in movement from something else anyway (like the coolant lines to the throttle body).

if you do the egr delete it makes a huge difference. Next to that I find the wiring thats bolted on the passenger side to be the biggest obstacle. Unbolt that and you can push the plenum to the side enough to change plugs without completely removing it.

Can we get before after pictures?
Great write-up. subscribed.

Re: The vacuum hose reduction: walkthrough and pics
wondering same question. Ive been waiting for this writeup. You did a great job struggly. Does this setup void emissions. EGR blockoff im assuming? Now i can finally clean up all that extra shit in my engine bay.

Re: The vacuum hose reduction: walkthrough and pics
i'm very interested in doing this. I've heard many times about doing the hose reduction, but does it serve any benefits aside from a cleaner engine bay? and does it alter the performance of the car in any way? since you are eliminating things like the egr and a couple of solenoids that are controlled by the computer. my car is a 95 spyder which has the cali spec ecu, can i assume my car falls into that category of the 94-95 hybrid ecu cars?
Re: The vacuum hose reduction: walkthrough and pics
You can use the purge valve to plug the front turbo intake pipe. I used a vacuum cap.
On 94-95 cars you will get a CEL by removing the EGR system, but using the EGR-T for boost logging and keeping the sensor may prevent this, but it didn't work for me so EGR stays. EGR will NOT cause you to fail emissions unless the inspector is doing a visual inspection and owns one of these cars...

Less chance of boost leaks from torn hose, cleaner intake runners from EGR removal, easier maintenance. Your not going to get faster.
