94 2.5L Swap question....

[Ghost]

ok for those of you that do not know I'm swaping in a 94 2.5L YJ into my 84 XJ. i was looking at the Haynes Engine control system diagram for 91 and later 2.5L and 4.0L engines and noticed something. Heated O2 sensor. Where does this mount on the engine? Or is it on the down pipe between the engine and the cat?

may i ask why not a 4.0?

Sure.....

It's an 84! 4.0 does not go in easly. The firewall and front radiator suport changed in 87. IF I want to do that much work it will be to swap my lift tires on a newer XJ! Ask Old Man, or is it Hoss that is doing the 4.0 into an 84-86 XJ? It's a PITA!

ok well i wasn't aware of that. Thanks for the heads up. Carry on!

Or is it on the down pipe between the engine and the cat?

DING!

Hmmm......

Looks like I found my first snag to my swap........ Now I need to find a down pipe or get a new one made! Excuse to buy the pacesetter header? Considerign that is the only one available!
