EGR removal...help?

[YakuzaKirby]

so my car- which im keeping. and not selling yet. has a combination bad head gasket and melted piston. so while im replacing pistons and installing my HKS 1.2mm headgasket... i really wanna remove that POS egr valve. its always in the way. it looks like some idiot designed it. and i'd definately just love to get rid of it.

if i simply remove the system and use block-off plates on the head and intake mani, will i throw any codes? will it run bad? should i run an old-school road-draft tube from the head to the ground? at the same time i want to re-route my valve cover breathers into a catch can instead of going to the intake.

is this an easy project to undertake? or am i better off leaving that junk where its at?

...will i throw any codes?

You will if it's a California car.

Before you remove that "POS EGR valve" that the "idiots" that designed this motor tuned the USDM ECU to run with it installed, you might want to read this:
EGR Effect on EGT

To answer your question, the correct way to remove it so your car can spew one of the most noxious pollutants a car can produce, you will need to remove the EGR cooler at the back of the head and block the exhaust gas port on the passenger side of the motor. Otherwise, you will have hot exhaust gas at the back of the head with no where to go. The port on the intake manifold has to be blocked as well. You will also need to source a JDM ECU to run the correct fuel/timing maps for no EGR, otherwise you risk detonation...and that can occur at less than WOT.

BTW - Search is your friend.

erm, thanks for the info, and i actually tried searching for it for a while and i couldnt find anything. the egr cooler on the back of the head is the rectangular aluminum box right? thanks for the info. lol

hey men..i have a cali car...and i am throwing a code 71...what should i do?uhm can i just trick my ecu by putting a resistor on the sensor?if i do would this affect the cars performance?

It affects the car by the ECU thinking EGR is flowing when it is not.
