Hey guys, I bought 89 YJ November 2011. Came with a crappy Carter carb and smog paperwork from October 2011. I registered it using smog paperwork provided by the PO and ripped out the Carter.
My current setup still has the EGR valve and the charcoal canister intact. Everything else smog related other than 3 vacuum lines required to run has been removed. Jeep is nuttered, running MC2150 from the ebay guy along with team TFi ignition upgrade.
I have smog coming up this November and need to prepare. My plan was to go with a 4.0 head while if possible staying away from EFI. Have any of you guys passed the sniffer with MC2100/2150 in CA? If so, what about the visual?
I called a smog place and they said since MC2150 is an OEM part for another vehicle, they do not require carb numbers. Now in order to pass visual, they do however require all vacuum lines intact, sensors connected, nothing plugged off, etc.. I wonder if I can pass as is, if so, I would like to swap in the 4.0 head and stay with the MC2150. If not, I will need to go EFI along with the 4.0 head.
