The good news is that Sedan or X i believe the 4.4i is the same block. With regard to the oil pan, alternator bracket/oil cooler lines and covers you should be fine, but I'm not sure what you'll do with the egr modules?? - Swap heads, that would kind of suck...

'Fade, Thanks for the reply. Until I actually pull the original motor, won't know for sure, but thinking I may just block off the 05 spot where the EGR's are. I can feel the protrusion on the 04 head where the gases go, but no outlet for it. Trying to figure out how the 04 deals with EGR situation.

I looked into this a while back when I had to swap the engine in my e70 that I hydrolocked while stupidly going through some water....
Here is the thread that had the most info: https://www.bimmerforums.com/forum/s...-swap-question The exhaust manifold bolt pattern is different on the heads (but there is a undrilled boss there) so you will have to drill/tap the head for that. Be careful with the oil pump, the pan is different so you have to change that but I believe that the pump is also a different part number. The oil pumps also cost something ridiculous like $850 new. I ended up finding a 70k e70 4.8i which was a direct swap and I didn't have to play around with the oil pumps. I do have the oil pump and pan that were still good from my original 115k hydrolocked engine. I still need to sell them along with the heads if you need to build it up before doing the swap. Strangely my engine just took out the timing chain guides when it slammed to a stop and didn't bend a rod or take out a bearing so most of the parts are still good (zero metal in the oil, etc). -Rich |

So as to not pass along false info, what Rbryant has posted is incorrect at least in my case and my scenario. The exhaust manifolds bolt up perfectly. Will just have to deal with the EGR valves and the rest should be good to go. Started to disassemble things tonight. Sent FCP $500 for misc seals/orings/gaskets and will hopefully be putting the "new" motor together this weekend and maybe install next week. Will keep this thread going and updated.

Either way, the good information is that there are several exhaust manifolds and bolt patterns in the N62 family and they sometimes require drilling and tapping if you mix and match. I was expecting only one side to be different between the e70 X5 and the engines I looked at from an E65 750i. Which is also different than the 4.8is. It probably all just comes down to how the exhaust manifolds fit best. Did you happen to look into swapping an N62B48 engine for the extra 40hp/40ft*lbs instead of putting another 4.4l engine in? Would it take more than just changing the control module? -Rich Last edited by rbryantaz; 05-23-2019 at 01:31 AM. |

In regards to the 4.8, I’d have also swapped if one were to be going through all this trouble. Transmission (torque converter) is also a different unit. |
