i read this up on Turbo magazine or one of those tuner mags out there.. they said something abt the gases tht are recirculated are dormant and are just in the system again to take up space.. and blah blah blah... i forgot what they said, but the bottom line is tht the EGR is supposed to give more power?

besides, taking it off will cause a CEL = failed smog

come on you cant tighten and untighten two bolts? if it frees up power than i want to at least try it.

u take it off, then how r u supposed to cover the hole? JB weld or any weld = no more EGR evar

block off plate

You woont free up too much power when your ECU never sees closed loop.

u could always try it and report back the results

imo, i wouldn't do it unless if u're going OBD1

i dunno an egr system doesnt make sence to me, we go through all the trouble to take in the coolest possible air and it just gets heated up anyway.

The purpose of exhaust gas recirculation is to dilute the air/fuel mixture at certain times to improve combustion/reduce emissions. You could probably achieve the same thing by injecting argon or helium, but exhaust gas is in plentiful supply. You have to use an inert gas, as if you just used air the oxygen content would lean out the air/fuel ratio (which is bad for emissions).

but the question remains, would blocking it off improve performance and what would you need to do to make it work? aftermarket manufacturers sell blockoff plates so i gotta think that maybe its a good idea.

IMO, just blocking it off wouldn't improve performance. Aftermarket mfg's also sell throttle body spacers...
