Hey Team

Managed to get block back from the engineers today so will start putting the engine back together as soon i have time during the weekends when i find some time.

While at the engineers he was telling me about his own little project that he's currently working on with all his 100 other jobs.

A Toyota V12 which he is making some awesome CNC ITB for it! So my project will be done when he gets to it hopefully not too long  

Here's a few pics of the two v12 blocks next to each other, I'm quite surprised how well designed the bmw v12 is, so compact and smaller but yet bigger in displacement than the toyota v12.

and a couple pics of the heads, Figuring out whether we can do a regind for the cams or to make them from scratch. 

Good old 1GZ V12. 

Who was it working on that?

I was considering putting one into a Soarer a while back, but canned that idea and bough my rare active suspension Soarer instead. 

They need an external or dry sump setup due to the location of the chain driven pump vs steering rack so costly from the get go. 

A nice sounding engine though, quite a few 1GZ conversions floating around NZ as of late.

Hey Michael

The guys at Hartley engines and motorsport. 

Nelson is the CNC guru, he's putting a lot of time and effort into making some off the self intakes for this motor as he wanting to start selling them on a big scale, check out their F.B page if you want to see one made up. Bloody bootyful piece of work. 

[zero 1162]

Are you increasing the compression ratio?

 

Thats cheap hp.

[No name user 379]

Worked on many projects with Nelson and Brian, good people down to earth.

[e46v12 477]

Yes i agree with you there crunchy very humble father and son duo. 

Yes Nathan we did discuss about shaving a bit off the heads themselves to bump the compression to 11:1 Nelson said it would all depend on how much room on heads he had to play with as we don't want to take too much off for valve clearance. We would have to start looking at custom pistons but that"s digging into deep for more pockets.

Found this while trawling the internet, not sure if you've seen it, or it's of any value, but it's a pretty thorough detailing of an M70 rebuild, http://bmwe32.masscom.net/sean750/engineRebuildM70/M70rebuild_1.htm

That's pretty cool. I love galleries like that, thanks!

[e46v12 477]

Haha yes i have flicked through that rebuild a few times EURO always trying to see what other people have done and any tips or advice they may have. 

I'm hoping to be putting the short block together next weekend so will have an update for you guys

Afternoon Team

So managed to get a bit more done yesterday.

With the help of my awesome mechanic mate Master G.

He brought his tool box with him too.

Unfortunately didn't get as far as i wanted as one of the piston bearings was really worn which i must have overlooked when checking them. So the decision to do it once do it right was applied. Managed to get the crank and main caps back on with the right torque settings. Put the new piston rings on the pistons and now just got to order a complete set of new piston bearings tomorrow. 

Managed to find the info online on torques settings. Didn't realized how many pages it was! as you can see pretty much printed a book. So if any one is looking for torque settings for any BMW motor I could let you know.

Also was pretty handy how the directions and pictures to install the rings were dummy proof. 

Wrapped the block up in glad wrap to keep the dust out. 

The crank spun so smoothly even Master G was surprised on how well it was freely spinning by hand after bolts were torqued up.

Really looking forward to bolting the dry sump on to see how compact it is.

Great progress. Nice to see it coming back together.

Has there been any more progress since August?

[e46v12 477]

Thanks Dave

Unfortunately it's a waiting game at the moment for me. The supplier i'm going through to get the new conrod bearings is have a bit of trouble with the suppliers in German. 

I don't know if your dealt with engineers before but they tend to take a very long time with one off projects as my heads are still at the same stage when i dropped them off 3 months ago. 

Other than that the motor would have been back together if i had those bits back.

But you know how the saying goes "good things take time"

[zero 1162]

What was done to the block, and what did it cost you?

[e46v12 477]

Hey Nathan

nothings been done to the block just an acid dip to give it a clean and checked for warpage, other than that pretty much standard. 

Is that what you were meaning Nathan?

[allan 295]

Is plastic gauge still available these days used to use it to measure the clearance on both main bearing and big end bearing shells.

Yea, thats what I was wondering.

It cost me $200 to get my v8 block cleaned and checked at Taylor Automotive.

You didn't get the block decked or resurfaced?

[e46v12 477]

Hey Allen 

I have read people still use it, but not sure if its a common practice used by many. Most just go by factory torque settings i assume.

Nathan mine was slightly more expensive but had a few more things done. 

Costed $600 but had 3 x stubborn bolts snap at the back of the block which had to be drilled out ( this cost the most because of set up time)

Blocked cleaned and flywheel lighten and resurfaced.

The machinist said the block was in mint condition no warpage at all, no need to be resurface. Just a light hand sand and that was it which i was very pleased to hear.

nice work  hey if you need any m73 v12 5.4l engine parts , I have got a mate with  2 of them sitting in his sheds

[e46v12 477]

Thanks Brent i'll keep that in mind.

How ever i could use one of them m3 whole rear ends when your ready to part with one  

[e46v12 477]

Morning Team 

It's been a while since the last post, here's a small update for you guys.

So spent yesterday (Sunday) on a mad 14 hour drive up to Auckland and back to pick up another piece to the puzzle. 

Thanks to Brent from BM World Ltd for coming out on his Sunday to sell me a rear end setup from one of his M3 wreaks.

Finally good to put a face to a name Brent  

Here's what I picked up.

I was quite surprised of how much bigger the diff and brakes are. Definitely won't be breaking them any time soon. will look at replacing all rubbers and get it all powder coated again before installing.

So just a question I'm hoping someone could answer. 

Are these parts interchangeable between the m3 and non m3? 

I didn't get the upper/lower arms or shocks from the m3 so am hoping my ones will be usable?

If any one could help me out that would be awesome.

Thanks Richard

Upper and lower arms are identical, and shocks are a straight swap also.

[e46v12 477]

Awesome thanks Brent and Nathan.

that link is a good one Brent i'll be saving that one for future references. 

[e46v12 477]

Hey Team 

Just a small update.

Did a little road trip up to Auckland over the weekend and picked up a 2nd hand set of XYZ 6pot 330mm brakes.

Thanks to Raymond for giving me a great deal.

But the high light of my trip was when i went to buy some fruit for the trip home around Greenlane. 

Saw this beast that caught my eye. I'd have to say the mintest 750i possibly in NZ.

I was lucky enough to catch the owner while putting his grocery's in the boot.

Donny is his name, brought this back in 96 brand NEW! at $270,000 haggled down from $300,000 WTF.

has all the bells and whistles as he got to pick what add ons he wanted.

Having AC Schnitzer body kit and 18inch mags made it look stunning. Custom two tone leather, T.V , Phone Sunroof etc.

And heres the kicker for a 21 year old car Donny's only done 90,000kms in it.

Had a good old yarn with him and took some pictures. 

I said this will probably be the only time i would see this.

Bloody awesome

Nice looking E38 7er! Was that engine all polished?
