I was wondering how you other people with 89 240sxs with the sr20det in it put it on? Any pics or diagrams or hell a discription would be great, I need to install the EGR so I can pass my local emissions test.

Thanks,

Josh

The reason people don't hook it up is because it would hit the steering shaft.
To install it would require you to weld a bung for the custom pipe you make from the EGR in a different location on the O2 elbow.

BTW I don't have mine hooked up because I'm lazy and just welded the hole shut. http://www.freshalloy.com/

Yeah I knew that I already have the sr20det in my car but my car failed at the emissons test just a couple of days ago on the Carbon Monoxide loaded test standard is:1.20 and i had a 6.27 D'oh and I figured if I found a way to put it on it would help.. that and an AFC my car is running really rich .

Does your cat *work* ? thats astronomically high. try to lean it out a bit to a more normal ratio.. or even if you can drop the boost to 0 and set it up to run practicly NA.. you'll make **** for power but it'd help past the test.. less fuel per RPM = less emissions usually http://www.freshalloy.com/

LOL yeah I just got a new random tech cat and yeah that is really high, but I don't have an AFC at the moment and well I won't be able to get one until I see what happens with my traffic court issue. Any other suggestions on how to decrease the fuel pressure without an AFC?

Thanks,

maybe a little magic tool named "adjustable fuel pressure regulator" http://www.freshalloy.com/

Yeah I thought about that when I woke up this morning. I was sailing with Capt. Morgan last night so my mind wasn't firing on all cylinders. But oh well I will be putting on and ADJ. fuel regulator sometime this week.

From my understanding, the EGR does not affect the carbon monoxide levels; the EGR is for controlling NOX emissions. Also, running rich would bump up the hydrocarbons, but it shouldn't raise the CO too much.

I think CO levels are maintained solely by the catalytic converter, but I will have to check on it.
