My E46 V12 6speed swap

[e46v12 477]

Hey Team 

Another long break between post, so managed to sell the black 330ci to a nice gentlemen who drove all the way from te puke to pick it up.

Short vid made by my friend and exhaust sound near the end.

So have also managed to get the n62 oil pump stuff sorted for the m62tub46 motor. I had a few hiccups with the sump pan fitting correctly but we got there in the end.

Also had to modify the cross member which the certifier was happy with.

This was the 1st change to the n62 sump

Shorten tubes and oil pump shaft

Had to make 6 new 10mm spacers to raise the pump up and slot the oil pump bolt holes to accommodate taller spacers.

  

The final Sump pan we ended up cutting the front off the n62 pan and reusing the X5 front 1/4 due to needing the power steering and air con pump tensioner brackets.

  

All bolted in on the motor now i reused the m62tu oil pump chain and sprocket.

Bolted the Flywheel and clutch it on

Tested fitted into the engine bay due to me needing to find if the n62 dip stick cleared which it does but needs to be shortened by 120mm 

Plenty of clearance underneath too.

Not long to go.

Thanks Team

Loving the fab work, looking forward to the next update

Any reason you went with a self adjusting clutch?

[Gaz 1060]

Great work, any reason why you didn't go for one if the off the shelf conversion kits? 

[e46v12 477]

@Cement Thanks though i cant take the credit for the work as it was all done from my engineer.

@Eagle I had the Jb racing flywheel lying around and it took factory a pressure plate. I also had both spare clutch disc and plate so figured i would used all the parts up.

@Gaz are you talking about the Cybul and Adamat ones? I did think about it but quite liked the rear sump idea and just wanted to try it really. 

[Gaz 1060]

How much slimmer is the f series shaft? Did it slide straight on? I'm about to start a m62b46 swap on my e36

[e46v12 477]

@Gaz its noticeable slimmer, definitely helps for fitment of the headers as every mm counts.

I had to get the top U joint swapped over to the e46 one ( i think e36 are the same) and i had it shorten by 20mm i think. 

Oh nice be nice to see one in a e36 too.

Hey Team

Happy new years

Been a while but have got so much done and a few plan changes.

Certifier has popped in, seen the drive shaft hoops and he is happy with the outcome.

Heaps of little jobs done to get the motor finally running.

Relocated the heater water valve, DIY oil catch can, relocated dip stick, welded O2 sensor bungs in, coolant and heater hoses, finished off the rear end of the exhaust, AC lines and other small stuff.

So I have had the motor running on the hoist for a good 10- 15mins to bring up to temp checking for any leaks or issues.

But ran like a dream, custom oil pump has pressure so very happy it has worked out. Cant wait to take it for a drive.

Also a massive update on the v12 swap, Nelson at Hartley Motors has started on the intakes using 3d printing to make the runners which will be glued to the alloy flanges, very light when I held them in my hands and look very cool.

But big changes in the direction with the builds now ( I know I change my mind quite often)

I'm going to twin turbo the v12 motor now instead of ITB's and I will be swapping the v12 in to my X5 4.6is manual.

The opportunity popped up which I thought would do more justice for the M3 rolling body.

I will be doing a S85 v10 manual swap into it   Cant wait to get a start on this swap.

Thanks Team.

Hey Team 

So Things are coming along nicely, Picked up a full manual swap from an e92 M3 and pretty much a complete S85 from a M6 ready for the E46 M3 project.

Cant wait to get this swap started.

 

[leonf 162]

just being nosy --------- what kind of $$ was on the s85 engine?   Asking for a friend....

[e46v12 477]

@leonf Lets just say above 5k below 10k  

[e46v12 477]

Hey Team 

So finally got the e46 v8 swap up and running, 

We had a small bimmer car meet over the weekend here in Palmy and I managed to get the car going and took it to the meet. It was great tester for the car and man was is it quick.

I did change the intake to an OTR setup, which meant I had to change the radiator which also meant i had to install a fan switch. It all actually turned out really good. 

Booked in for a cert in late April too so hopefully get cracking onto the M3 v10 swap soon.

Love the intake, custom made?

[e46v12 477]

@Gaz its a OTR (over the radiator) intake made by x-air for a holden commodore. If you google OTR intake you'll see heaps of different styles

Looking forward to the e46/v10 build, that’s the dream right there. Please document it.

Any progress updates on the V12? I've been thinking about the V12 swap for a while and can't wait for more progress. Excellent thread. 😉

Hi @zenwafle no real updates but im not sure if your read the post as im putting the v12 into my e53 X5 4.6is and twin turboing it instead now. The v10 will be going into the M3 now.

Here are some pictures of the v12 intake runners being made. which will then get a plenum over the top.

 The inspiration? What awesome projects - V10 E46, and V12 E53 will be mental!  

[e46v12 477]

@Kees if only i had a Mclaren motor  but yeah they will be cool once ive finished building them. Im also keen to do another roadie up to Aucks at some point to stretch the legs of the e46 4.6is swap. 

[e46v12 477]

Hi Team long time no post.

Sorry been busy with business move, other side projects and abit lazy in the posting.

So plans have changed a bit, The v10 will be saved for a nice oldschool bimmer, not sure which one yet.

E46 M3 will be getting a N73 v12 motor from this beast.

I will be on selling the m73 stuff to fund this swap.

Also in the pipe line have this e46 330ci coupe. 

Looking at dropping my last 4.6 motor into it. Have an Elate supercharger adapter plate, water to air cooled. 

Modified AMG supercharger and 420g 6 speed box with my spare M3  rear end.

Rear subframe plates and driveshaft hoops welded in. Stainless headers, engine mounts and gearbox x member.

Just sorting out the oiling by modifying the x5 one. 

Cant wait to get this thing running.

Thanks
