How hard is this going to be to put a 2003 1MZFE from a Camry into a 1998 Avalon that also had a 1MZ engine. What external parts will need to be swapped if this is possible at all. Hoopefully not anything internal. It's the lowest mile engine I can find on the cheap for my Avalon.
the 848 is prbaly a lil more fun to flog but if you EVER think you may sell it, get the 1098. Nobody will pay much for a 2nd hand 848. For that matter, get ready to open your wallet quite abit in the future.
