EGR and ze
is there any advantages or disadvantages to hooking up the egr on the klze?

it wont matter at all. Because there is no EGR port on the ze. You can hook it up(theres bolt holes) but there is nohwere for the gas to go.

mm IIRC there's a block off plate but you can remove it..so you can use the egr..anyways , egr is no good because it recirculate hot exhaust into your intake (hot and dirty= not good)

I dont rmember a block of plate onmy motor...there was nothing there at all.(but i could alwasy be wrong) Oh and the egr gasses are hot but it actually COOLS down the combustion chamber.babyblueMX3 wrote:mm IIRC there's a block off plate but you can remove it..so you can use the egr..anyways , egr is no good because it recirculate hot exhaust into your intake (hot and dirty= not good)

how can exhaust dump into the intake cool down the combustion chamber ? I'm not doubting you just want to know why..where the egr gets the exhaust (about 8" from the heads) it's the hottest place it could be.

From what I've noticed the KFZE's have a cool little block off plate, but the KLZEs don't have anything there. I personally got rid of all my EGR hardware on the KLZE in the MX3. On my old Probe we left the EGR valve there, but we cut the tube and welded it shut to use as plugs.

Actually.. he is correct.. the reason it cools down is because of the lower o2 content.. and yes the engine does run richer as a result. But a richer mixture burns cooler than a lean mixture. The recirculated exaust gasses force the temperature down in the combustion chamber because there is less oxygen to burn. It also reburns that portion of the spent exaust gasses for cleaner emissions. Lots of people remove the EGR system because it does rob a small amount of power. If you dont run with the EGR system.. you should pay much closer attention to your timing and make sure your cooling system is operating as efficiently as possible since the combustion chamber will run at a hotter temp. Here is an example.. DONT TRY THIS its only to make a point. If you have a bucket of gasoline that has been sitting for a few days, and you drop a lit match into it.. believe it or not.. the match is most likely going to extinguish (depends on how much fuel vapor is present above the main liquid portion of the gas) but.. if you fill a spray bottle with gas.. and spray a lit match with it.. it will flame up every time. While gasoline is flammable.. its the vapors that are REALLY flammable and become more flammable as their molecules mix with oxygen molecules. So.. the fewer gas molecules mixed with o2 molecules will result in a leaner hotter flash burn rather than a cool even burn. This is why when you turbo a NA engine.. you usually have to go with bigger fuel injectors or you run way too lean.. running too lean can burn valves or cause detonation (very bad for internals). Hope this helps.
