Any idea what the part number of the steering Rack is? I'm trying to get one but PITA looking for one.

You can look on www.realoem.com for part numbers specific to your model.

Need the one for the e92 M3 4.0 steering rack part you got. OR are you saying that this could vary depending on my vehicle (07 e92 335i) ?

Edit*

Is it this one?

I just bought a second hand one. I got it from Brintec in Sydney. If you look back on this thread it was mentioned that someone had a couple spare.
The illustration you linked is a diagram of the standard steering shaft. I think the US M3 shared the same one as the 335i. I believe you need to specify an Australian part number. You could do that by entering the vin of a known RHD m3, but I would try finding a second hand one first.

While I have the outlets removed, I decided to install the M3 steering shaft that I have had for a while now. The photo below shows the differences between the M3 shaft and 335 shaft. The M3 shaft is heavier and thinner but because the M3 shaft is bolted to the top universal in comparison to the 335 shaft which is welded, it is bulky in this area which is where the RB large silicone outlet passes. You can see a slight wear mark on the 335 shaft about 25mm from the top where the outlet was rubbing after initial installation.





Installation of the M3 shaft was fairly straight forward. Now I have to make some aluminium outlets. I have started the design work. I am going to use 44mm (1.75") pipe to the turbos and 76mm ( 3") to the IC. Also, I want to reinstall the standard coolant expansion tank. I doesn't look that difficult. Famous last words.

great work guys...

Its a shame the collapsing point on the steering shaft can be reversed so it sits at the top? That would almost allow a straight pipe?

You can't reverse it. You'd have to cut it apart and switch the shaft around and re-weld, all in proper alignment.

I don't think that whatever restriction is created will make too much difference. It will flow a lot more than stock. Look back up at the pics of the pipe size differences, and the compression of the stock pipe and size of the v band connector.

As I am currently working on building a set of aluminium outlets for my Super RB Evo turbos, I require to form a bead around the ends of the tubing to prevent the silicone joiners from blowing off under high boost conditions. When you Google pipe beading tools, the cheapest available is a Proflow for around $180. I wasn't going to pay this so I came up with a cheap option that I thought was worth sharing with the forum members. I had an old set of multigrips laying around so I used them and attached a 5mm wire rope grip which I bought at Bunnings for $7.50. This works great and only takes a couple of minutes to complete a 44mm pipe end. The photos below show the results.

Good stuff Ghetto bead roller TM.
I've seen some other ways to do it on YouTube but most needed a lathe.

It seems to work ok Phil and it is adjustable. You can make the bead higher by putting some packing (nut, small screw or folded aluminium, like I did) under the wire clamp.

Genius.

I completed my fabricated outlets today by getting Brisbane Aluminium Welding to weld all the pieces together. I was worried that some of the pieces may not end up in the correct position but it all came out ok. I am going to purchase some heat protective sleeves to place over the silicone joiners. Hopefully, this should meet my objectives of being able to adjust the steering wheel back to a higher position without the steering shaft touching the rear outlet and using a standard OEM coolant expansion tank again. I used 44mm (1.75") OD tubing for the outlets from each turbo and a 63mm (2.5") collector for entry to the IC. I was going to use 75mm (3") but the area of 63mm (2.5") is greater than the area of 2 x 44mm (1.75") pipes.

Nice work.
Have you test fitted this yet?
Does the slightly smaller diameter outlet piping clear the steering shaft without further modification?
My outlet is still 2 or 3 weeks away.
Are you planning on offering these for sale, and if so, how much would they cost?
The ones I'm making have the tapered CNC alluminium flanges to utilize the C-clamps for turbos that use the stock connection. Mine are slightly larger diameter outlets and same size collector (2.5").
The larger size outlet piping requires the fillet reduction for the rear turbo that has been taking some time to get right.
Have you changed your engine mounts? Because that will stop the engine (and therefore the outlet) leaning toward the steering shaft and give you more clearance.
This is great because now there are two solutions for different turbos including stock.
Looking forward to hearing how your system performs.
Also good call on the collector pipe size. If you went 3" you'd lose velocity in the airflow to the IC.
I've been running my beta version for a few weeks now and I love it. I'm looking forward to getting the final version back and installing that. Then I can turn left and right

I haven't completely installed the outlets since getting them welded yesterday but initial install appears ok.



The rear turbo outlet pipe doesn't hit the steering shaft. I have just fabricated these for myself. I had to make a couple of wooden moulds so that I could shape the pipes going into the 2.5" outlet pipe. They both broke but could still be used when clamped in a vice. They did the trick anyway.



No need to change engine mount as the rear pipe on mine goes around the back of the steering shaft as per the RB silicon items. Once I get some heat shield sleeving I will install them and let you know the results. Testing will then be required to ensure they stay together under 26psi boost conditions.

Thanks Shane. I just hope it all works ok. I am just waiting for the heat sleeving to arrive before installing it. With the heat sleeving over the silicone joiners, I should be able to go back to the OEM location for the actuator solenoids again. I will let you know the outcome.
