RB Hotside Silicone Outlets
Has anyone in Australia installed the RB Hotside Silicone Outlets onto their car. If so, how did you stop the outlet rubbing on the steering shaft or do you just let it rub.

I've seen one installed on a RHD car and the outlet was just touching everything.
Might be able to get a few more mm of clearance if you get an M3 steering shaft which is solid instead of hollow, and a bit thinner. I have retrofitted an M3 steering rack and got the M3 steering shaft as well. The steering shaft is interchangeable even if you don't have the M3 rack http://www.1addicts.com/forums/showp...&postcount=178

Whats your views coupes on how easily a hardpipe style outlet could be fabricated? Since you've spent a bit of time under the car and hands on with the rb outlet id appreciate your feedback
Im considering VTT GC lites as they have 20% off to replace my rattly oem turbos and was discussing the option of fabricating a hardpipe outlet with my local bmw tuner. He's keen to tackle it based on pics ive sent him. Id prefer a hardpipe for reliability and improved fitment (having a proper rhd solution) |

Pic here: https://www.ebay.co.uk/itm/BMW-3-SER...wAAOSwak5Z11Uu I actually have a M3 steering rack in transit currently, when it arrives i can take pics for you and dimensions (it just left the UK should arrive late next week) Could you use some clamps to squish the silicon somewhat and mount against the firewall?

It is indeed a genuine BMW part. Might be a thing to increase clearance for the V8 motor, although the 1M uses the same steering shaft. The LHD m3 steering shaft looks similar to our standard steering shafts.

Fair enough Vince. I will see if I can track one down as back up to any other solution that works.

Hoper's thread... Brule's http://www.e90post.com/forums/showth...=976234&page=9 so from memory, you have to drill a hole near the heat shield and use cable ties to pull it away from the steering shaft. Hope this helps mate and good luck. Last edited by Montye90; 11-20-2017 at 08:55 PM.. |

Here is Rob Beck's latest reply to my issue with the outlets. It may be a help to others.
"Considering the growing relatively soft market on RHD outlets, combined with the overall lack of complaints, further combined with degrading profitability; we likely will not re-invest in making any further advancements with the outlets. Regarding the drilling you may want to contact Brule as we’ve combed through many of our emails from well over a year ago and can’t find the one where he did the drilling mods. During the searches we did find numerous other clearance pictures he attached and they seemed well which are also attached to this email. We also found this DIY from a member named “Hoper”, he was installing the RB RHD High Flow outlets (for stock frame turbos which are a bit smaller) but he seems to have referenced Brules directions and has a good how to on the drilling here (post #15): http://www.e90post.com/forums/showthread.php?t=1341897 (Note: This process should work the same for either of our outlets, whether for the stock frame housings or the EVO style housings.) Another option would be to find a tight radius aluminum (60*) bend, cut it to a specified length to fit your needs and bead roll the ends. This will get a smaller diameter (1.75” OD) vs the ~2.125” OD of the silicone which will free up quite a bit of additional space. This would require cutting the approx. 60* bend out of the silicone and utilizing 2 more clamps to insert the aluminum bend (all cut to length accordingly). Just an alternative idea that may help out here if you do not wish to use the large zip ties or do the drilling. Not sure if you maybe affected but a couple other things to consider that would affect fitment: 1. Possible alteration of the turbo compressor housing outlet (please let us know if this is a possibility) 2. Motor mount has been compromised over time (many use the 335is mount as a replacement) Thanks, Rob" |

Thanks 135. I am aware of the steering shaft that Duck has as I was talking to him yesterday. I had already ordered a M3 shaft so will see how that goes.

Ducks shaft was welded on a standard steering shaft and got rid of the OEM accordion piece for crash safety. While reason for that is to stop the steering wheel from going into your chest in an accident.
Imo an outlet on N54 really has to be made out of metal. Even the BMW use steel/aluminium for it and they are known to use cheaper plastics whenever possible. That fat silicone outlet just looks unacceptable to me, touches everything, would rub through eventually.

Would any of you guys be interested in buying a hardpipe outlet pipe if a few of them were fabbed up?
If I'm to go with VTT GC Lites I'm going to get a hardpipe fabbed up, may make it cheaper for everyone if we were to get 3-4 of them made up at once? |

I don't want to spend a bucket load with Hill Eurohaus to install them and then have them removed again... Having fab'd up hardpipe with a heat coating is a good idea. |

I am not sure whether your hard pipe outlet concept is for just going around the steering shaft or the complete length down to the IC. If you fabricate a complete hard pipe outlet, it should be designed to go around the standard OEM coolant expansion tank so that it doesn't have to be modified or relocated.
