yup agreed but I guess what i was indicating was that perhaps it wont be worth my while my do 2-3 kits for other guys if they have niggly fitment issues.. id be doing r&d soaking up time and $ for no gain potentially?
should know more by the time i do mine i guess to determine if a few more sets can be done! |

My stockers are smoking like a biatch so I'm really needing to sort out this outlet situation so I can do it all at the one time. I don't think I can drive my car any more due to the smoke, so it's getting urgent now. As has already been mentioned, if the outlets finished where the stock ones do each person could use a coupler specific to their individual ic. Dusty's outlet looks great and we only really need to address the rear outlet/steering shaft area. The rest (from washer pipe forward) should be same as LHD. I'm wondering whether the rear turbo connection can be cut off his one and reconfigured for our needs, or we start from scratch. I spoke with him a few days ago and he said he would try to get hold of an oem RHD pipe and see what he can do. If a few of us got together perhaps he may make up a run for us. That's another possibility. |

I don't know how serious he was at this stage. They know that there won't be hundreds of RHD customers, so we're not too well catered for. I guess we could buy his LHD and mod it here. I know it adds to the expense but maybe cheaper than reinventing what has already been R&D and tested on LHD vehicles. He also sent me horror pics of melted inlets/outlets, ones worn through from rubbing, and a few cross sections showing major flaws (90% occluded). They are all made in China I believe. |

I reckon the FMIC portion of the outlet would be fine, this was a part I asked if he would sell separate (I was thinking the y merge would be somewhat tricky to fabricate and could save some $ by just modding other pipes and silicon joiners to accomodate the PSP MMP style outlet to fit RHD.. Yeah unfortunately it seems relatively common to have outlet failure, but according to RB the failure rate is very low (I cant believe that or either they're all too new and once in service a few years will start degrading from the constant heat cycling and will start to fail then) When will you be installing your turbos do ya reckon? |

The TFT inlets for RHD go around the back of the steering shaft. Any larger outlet solution (with the exception of an unsquashed pipe) for RHD will most likely wrap around the back of the steering shaft as well.

Do 1M's have the M3 reduced dia steering shaft? (just curious not indicating this would be a solution)

I think once a custom set that fits RHD is made from aluminium and perhaps using an oval profile in critical areas to maintain clearance but also flow it could be easily duplicated and would definitely have a niche market...

Guys,
Having personally witnessed some cool things like am m54 turbo which started as an after hours fUc$ around turn into a full custom everything build making 245rwkw on 6psi stock motor with almost 300k (might be an e46,36 and 30 product for under 10k) or as far as I know the words first r34 with complete vr38 and 4wd conversion in literally 2weeks, I had the pleasure to witness some of the finest fabrication I've ever seen. For the n54, some of the lengths you guys go to is quiet amazing. But the fact is we should not have to. Silicon touching rubbing everything, having to cable tie shit around steering shafts wondering when it will fail, bashing things out with mallets etc, anyway you catch my drift. Personally most of these products seem backyard in standard with little to no science and everything seems to be a compromise of sorts or simply just rubbish. I know there is a custom turbo project going on for our market various other bits and bobs which is awesome and im sure the end results will be great. There really needs to be more of that. To make these hard pipes work is totally doable if the demand is there. Il probably do myself one in the future and put it out there, not sure. Making a setup with a various multi fit is probably doable also, I don't see the big deal. Anyway if anyone is keen and we get a group together we could easily make it happen. |

as the other chap already described they are allot thinner. it seems to me bmw went no compromise with the s65 headers and given its na, probably couldn't not afford to but it does not explain why the 1m unit is the same as the m3. perhaps there is also some other science behind it, who knows. il take a photo of my own unit to show you guys fitment / clearance. give me a little |

That y merge is beautiful and as you say we can use the front piece, and have the rear piece fabricated to go behind the steering column. We could do that part here. MMP stage 3 require silicon joiners, while most other hybrids can use the v band as supplied in the PSP kit (correct me if I'm wrong). |

So there's that plus melting, cracking, bursting, popping off rear turbo, which is inconvenient when out driving... |

All this said we do not claim these will last forever and they will NOT have the longevity of say aluminum or steel, obviously. But they have done REALLY well all things considered, and unfortunately the competitors products seem to be doing the talking when really it is apples and oranges between ours and theirs.

Getting answers to such seemingly simple questions seems to be difficult, not with your products specifically just everything generally. |

In short the fitment on the RB N54 Standard Frame High Flow RHD outlets is very good, if it were not we would have heard a ton of grief and we would not have distributors buying more and more across two continents. Our product talk aside we do support an aluminum product as being superior when it comes to durability, longevity, etc. Fitment will be a bear, however, without making the setup numerous pieces and with each piece will require just another length of silicone for a coupler along with a couple clamps (and thus a couple more potential leak points). Ultimately it is going to be a difficult endeavor to do it most ideally, no matter how you look at it. Thanks, Rob Last edited by Rob@RBTurbo; 02-15-2018 at 07:53 AM.. |

For anyone thinking of buying the RB EVO Style outlets, just remember that the OEM coolant expansion tank (RHD) cannot be used as the bottom hose outlet fouls with the silicon outlet. This is not a problem with the standard frame style outlets. One solution for this is to relocate the tank to the ODS of the engine bay by purchasing a 335D coolant expansion tank and power steering oil reservoir bracket. However, to do this, you will require a 335D style CP to clear the bottom hose outlet on the 335D expansion tank. (VRSF sell these). In my case, I already had a ER CP and Forge DVs which I didn't want to replace so I modified the RHD expansion tank which so far is working but long term reliability maybe an issue. I have just mentioned this so people realise there are additional costs involved apart from the cost of the EVO Style outlets. But if you are installing the Super RB EVO turbos, there is no choice but to use these and make them fit. An aluminium item which would be a smaller diameter and didn't foul the RHD coolant expansion tank would be ideal.

Any value in these for stock turbo guys? I remember peter fiddling with the stock outlets years ago in someone's car but not sure if it made power (I've been out of the game for a few years).
