Understandable. We all hate it when these mods go wrong. I have a friend who did this not too long ago, I'll ask him to chime in if he used different parts.

Just hoping that this solves the shuddering issue while steering, otherwise it's a new pump. Lol. TY all. Know it will be worth it in the end |

EARLES FITTINGS WORK!
Well, I think today I confirmed that the pump is just not powerful enough. Replaced the hoses, bled the system, and no leaks. It is definitely BETTER, but it's noticeable. The shudder is most obvious during the time that it would be most difficult to turn the wheel. When not moving. Once moving it's a little more pressure from 0 degrees to 45 degrees left/right, but once you pass 90 degrees it's smooth sailing and the steering is very easy all the way to lock. No weird noises, no humm or anything. I might just drive with it and see what happens. Might make things more difficult on the AutoX course (shudder during rapid steering changes), but I think on the full track it will be fine. Now I go look for a better PS pump and bracket.... |

Just an FYI for anyone swapping these new generation racks into an 06-07 wrx wagon chassis, i have some input to add from my experiences.
I just completed the install of a 18 STI rack in my 07 WRX wagon. I had previously installed the caster adding STI control arms so the track width is equal to the GD STI. I also had the Whiteline Bump Steer correction kit which made a difference in the outter tie rods over the oem. Parts used are: 18 STI rack 2 M10x1.25 60MM bolts 2 spacers (I used the Kartboy endlink spacers for this) 2 Washers and lock washers for the 60mm bolts 2 Audi Jam Nut PN N10218708 07 WRX Steering Rack 4 bolt bracket 06-07 Wrx/Sti Whiteline Steering Rack bushing kit (used all bushing in the set) The only parts that required trimming were the Whiteline outter tie rod ends. Like everyone else, i trimmed the rounded off end up to the point where the flat areas exist for a wrench. This coupled with the thinner Audi Jam Nut leaves more than enough adjustability without the need to cut the inners at all. I measured my WRX rack that was already aligned for the STI control arms and it measured approximately an inch and a few cm longer than the 18 rack with the cut whiteline end links bottomed out. The subframe required the usual clearancing for the 18 rack to fit. The spacers were mounted above the lower ear and below the higher ear on the rack making the flat mounting bracket from the WRX sit perfectly flat on the driver side of rack. The passenger side used the WRX C bracket as per usual. It should be noted the entire 06/07 Whiteline Steering Column bushings were used with the 2018 STI rack. The lines required zero modification and the rack is fully functional with no weird pressure issues as of yet. The wagon was aligned and is completely straight, with a tight feeling and perfectly fitting 2018 STI rack. |

Document of parts required for hoses and adapters-Please comment!
I know I posted a list of resources, but I went through an extensive search for steel or Stainless fittings a while back. I ended up finding them on Ebay. There is an increased risk of fire if a fitting leaks or breaks. A friend just had a hose leak which started a fire. Fortunately he had the hood up when it happened and had an extinguisher at the ready.
I'm a little irked when people say a fitting works or doesn't work and only references a brand. One Russell fitting 670520 does work on the rack. So, partly, I'm trying to clear up confusion and put things in one place. I have compiled this Google Doc list of parts that I have used to build three different sets of hoses and the adapter fittings required to switch over to using AN hose ends. Please review it and recommend any corrections or additions. Please let me post it here in the thread once the document is amended accurate and complete. I don't want to publish anything that is inaccurate and I'm sure someone will have a hose or fitting recommendation to add. |

Thank you for compiling that. It looks like a pretty comprehensive list, and you have the fittings that definitely don't work identified as such. I'll put a link to your post in the OP, so please continue to update/edit that post if you can as any changes are made.

Thanks, I will keep it updated.
There are some other adapters that work up top, like banjos. Just depends on what your setup is and which pump you run. Information collected about pumps would be helpful. Is there a list/link for all the power steering pumps that interchange? Which ones are high pressure? I haven't felt the need on my '08 race car (without quick rack) and my '07 with the quick rack is not finished/drivable yet, but I think I got a higher pressure one for it. Some might want the inlet on the side of the pump and some might want both the in and out on top. If the inlet were tapped (threaded) I think an ORB fitting would work. |

I'm not really sure what all the options for pumps are either.
I'm using a pump from a GR WRX, and it seems to be just good enough. It's still a bit weak/loud right off idle, but it doesn't feel like it cuts out like the stock 04 WRX pump did. And at speed, it's perfectly fine. I would think the best option would be the 2015+ STi pump, but I'm not sure how direct of a fit it is. To use the pump from the GR (onward?) on a GD, the 04-07 (and up?) pump bracket must be used for 03 and older engines. I remember somebody (MRSaturn?) talking about a group n pump that was a direct fitment, but pretty pricey. Another option might be to just fit a smaller pulley to overdrive the pump. Edit: someone was making specialized adaptor fittings for the non-threaded pump fitting as well. Possibly MSI or IAG? If I'm remembering correctly it was a banjo adapter Edit2: MSI -6 ORB MSI-MSISUB01-00-030 Last edited by T-37; 07-30-2020 at 12:21 PM. |

When you said the lines required zero modification, do you mean you didn't have to buy any adapters like everyone else here? You disconnected your lines from the original rack and connected to the new rack? |

Curious to see if anyone in here that has done this swap, has had any issues with the VA rack leaking?
Only reason I ask, is I have seen so many 2015+ STi racks replaced under warranty here at my dealership. |

I haven't yet. But it's a valid question, and it's been a concern of mine for a while. I know a guy that had to have his replaced on his '15 under warranty a few years ago, plus there have been a decent number of posts about leaks on nasioc over the years.
Subaru may have fixed the problem as the current part number 34110VA121 has superceded 34110VA120. But I definitely have a 120, so we'll see how it goes. |

I did include the premade 30" Fragola hose in my list. I am curious if you have noticed any performance issues or pump noise at low RPM's? The stock OEM return hose from the rack has a built-in restrictor and/or check valve. I eliminated it on the race car and only notice a little balkiness at creep speed in the pits. My return line is like yours, 3/8" or -6AN hose. I did only the high pressure line on a friend's car. Haven't run my other STI yet.
Why buy an expensive premade, high-pressure return hose and then add a barb adapter section where it connects to the reservoir? Why not use one AN hose end fitting and a cheaper piece of 3/8" hose? The return is not high pressure. Perhaps for looks? |

Yep, completely for looks. I'd love to get an independent reservoir that has all AN lines, but I doublt that will happen. Truth is, it might just be BETTER to use a standard line over the AN because it's less stiff and moves better. Just need to make sure you get the right kind (they sold me a fuel line first), then had to explain it was for a PS line. |

Crazy, where do they typically leak from?
Maybe it's better that I stick with a slightly underpowered pump |

I do get a whine at startup. Replaced the top seal at the output shaft to fix a leak... anyone know how to restrict the return line to mimic the OEM lines?
Swapped my PS pump and all rubber lines thinking I was bringing in air through the suction hose. If it’s the missing restrictor that would end my pursuit of this leak but I would love to add a restrictor to solve my PS whine. |

well, that's disheartening. I thought the change in the part number was because Subaru used a different seal to stop the leak. So now, whoever is repairing their pre-19 15+ STI racks are repairing them with bad seals?

Maybe its also beneficial that the GD chassis is lighter than the VA and could cause just enough reduced stress on the rack that it doesnt leak?... Wishful thinking

I'm going to see if I can find my return hose and clear this up once and for all. I think I kept that section. |

Just installed a 2015 STI rack in a 2002 WRX my son and I built. I cut 12mm off of each inner tie rod end and then used Moog ES-2972 outer tie rod ends.
Without having a decent band saw setup I did not want to attempt to cut the outer tie rods since that is the locking face for the jamb nut. The Moog tie rod ends are 12 mm short than the OEM. They do not have that slight angle the OEM has, but at the ride height we ended up with that was not an issue. |

Keep an eye on those moog tie rods. I've had bad luck with moog ball joints only lasting a couple years.

Yeah I had some concern as well - not what they used to be. I have seen poor fit with their wheel bearing assemblies in Subarus as well. This car is just a daily driver. I may take the OEM to a machine shop and have the ones we took off cut properly.
