blocked off EGR
 

Ive seen some block off plates for our Supras EGR valve. i thought it was needed? can someone tell me the advantiges of this. but it does make sence because why would you want exhaust gas back in your engine?!

I simply did a search on this forum and came up with this thread. Hope it helps. Also try searching for just egr removal, etc. There may be more threads.

Removal will not get you more HPs. but a cleaner engine bay.

I was about to do it, I even ordered the block off plates, but cancelled my order after someone reminded me I live in CA (although I do have hook-ups), I want my car to be legitimately street legal. You won't need a block-off plate for the back of the head, as these two plates are all that's needed to effectively delete your EGR.

Let Me Know How The Block Off Plates Work I Just Ordered Mine. Thanks

when you block off the egr what does it do? If someone could explain the whole thing it would help. thanx

here is egr explained

I read somewhere that while the egr helps emissions, it also lowers the temp of the last two cylinders (because they get shafted by the cooling system in a straight-6), and the egr valve closes at WOT anyways. (i just read this somewhere, so i can't guarantee accuracy)
