oxygen sensor

hey guys i was wondering. I cleaned out my cat about 6 months ago and then i put on a test pipe, and i have been throwing the same code it is cutting my fuel and causing me to run VERY lean . Do any of you know where i can get an O2 simulator? My friend said that was the only way i could fix it.

motor swap for 2g eclipse

I have a 1999 mitsubishi eclipse rs and i have been looking into a JDM motor swap. I was looking into the 4g63 cyclone but im told that it wouldnt mount up right and it would be very hard to do. What would be a good turbo motor i could swap with?
