2003 E53 4.4L 6MT swap?

Good day all!

Some of yous may know my other thread concerning my 2004 project... Well, I was considering doing a manual trans conversion to eliminate the auto trans issues I have been plagued with... But all the information concerning it doesn't allow the conversion to keep AWD and be reasonably cost effective... So, I'm going to keep waiting until I figure out that little part of the vehicle.

However, I was looking at a 2003 4.4L, but I found a 2002 4.6is that would be a great candidate for a RWD 6 speed manual trans conversion... I've loved both E53's I've owned, but they were both 4.4L and no manual... I don't NEED AWD here and it may save me some fuel costs in the long run... I already have a 540i 6 speed trans in my garage. Yep, I have a spare 6 speed... and most of the parts are becoming available in the pull-it-yards.

So, the reason for this post. I wanna know what yous think about a 4.4L 6 speed manual E53 (RWD)......

Thanks all!

EDIT::: I ended up getting the Imola Red 2002 4.6is...

Cheers!

I say why not. There is a guy that did a 5mt or 6mt on a 4.6is and am not sure how much it cost but that is thread to read if you want awd. Other than that, sure why not, since it is either doing this or getting an e39 m62 wagon with a 6mt.

I saw Nick's blue AWD 6 speed... he had extensive costs involved with getting the trans to TC adapter made... still incredibly amazing!

I found a 2003 4.6is, but didn't want to molest a rare example... Imola red/black...

It might take me some time to effectively work out all the bugs and keep it all stock! The goal is to use only what BMW has already made... Either from another X5 (3.0L) or another chassis line (5 series)... a few tweaks with the laptop to program the modules and such... I will probably be forced to have a custom drive shaft made, but that might not be much more than the cost of a replacement...

I'm excited about getting this one started since all my other projects are getting wrapped up and finished...

I guess I'll just use this thread to keep things in one place once I get this going strong!

Thanks all!

Cheers!

Does the ZF 320 bolt to the M62? If so you could just use 3.0i stuff. That's how I'd do it to keep AWD.

If you just want RWD, slap the 6 speed on it and get a driveshaft lengthened. The new base X5's are rwd only too.

I'd take a RWD only 4.4L 6spd. Very cool project if you decide to jump into it. Definitely keep us posted.

None of the drive line items from the 3.0L will work on the 4.4L... The only thing I'll be pulling from the 3.0L will be the shifter related assemblies...

Flywheel, clutch, trans, wiring, and hydraulics will be from the 540i... trans mounts and wiring might be my biggest tackle to keep stock (plug and play)...

I'm going to see about the project vehicle today... sourcing parts will be time consuming and I still have a lot of research to do on coding the correct modules and such...

All this will be done! And done with as little cost as possible, not counting the project vehicle... I have $400 in the 540i 6 speed trans already... I'm going to look at the 540i that hit the pull-it-yard this past week... Maybe it's a manual and I can pull all the clutch stuff I need from that one vehicle... not many E53's in the yards yet and only a handful of them will be manual 3.0L's... I may be forced to use Ebay or go to the stealerdhip for those items...

I'll keep yous guys and gals posted!

Cheers!

Subscribed just to see how this plays out. I'd LOVE to do this swap on my 4.6 and ditch the heavy/useless/high maintenance AWD hardware.

Well guys and gals, the project vehicle I looked at today needed far more work than the price allowed... So the search continues! I know of an Imola red and black 4.6is that I would love to convert to the RWD side, but I don't want to be "that guy" who ruins a nice example of a rare breed...

So, I was looking at the trans cross members. That is gonna be a chore to work out... I guess I'm lucky in that I have both the X5 and the manual trans version 540i that I can inspect up close to figure this one out. I still might be forced to fabricate the cross member. However, if the stock X5 cross member will bolt up backwards, I might be able to get it to work with little fabrication... I suspect the transmission and transfer case together will be longer than the 6 speed by itself... I'll try to get the exact measurements this weekend!

Well, that's all I have for now. What are your thoughts on converting one of the few Imola red 4.6is' over to a RWD manual?

Cheers all!
