Some of these (maybe some others as well) final drives are incorrect. Such as...

^^ agree. From http://www.cars101.com/subaru/imprez...7.html#limited
07 STi>> "6 speed manual, 1st: 3.636, 2nd: 2.235, 3rd: 1.521, 4th:1.137, 5th:0.971, 6th: 0.756, final 3.545, reverse: 3.545" Can a mod change this on the first page? |

It'd be easier to change the nomenclature. Those are the correct rear end ratios. Subaru has been known to use a 1.1:1 gear in the driveshaft.

Those FD's are correct for the transmission. The 1.1:1 center diff is confusing people because the rear diff won't match those numbers. It might just be best to add another spot for the rear diff ratio as well. That would be a more complete set of info.

It's important to note the 06 usdm 6mt is different from the 04, 05, and 07. It uses the same diff ratio as the 07, but with a different 2nd-4th. Last edited by Fierysun; 04-29-2013 at 03:46 PM. |

Something like...(maybe even adding the type of lsd for a more complete table/chart) All-Wheel-Drive 5-speed Transmissions USDM 3.454 / 1.947 / 1.366 / 0.972 / 0.738 / 3.900FD - 3.54 R160 (VLSD) '02-'05 USDM WRX 3.636 / 2.375 / 1.761 / 1.346 / 0.971 / 0.756 3.900FD - 3.90 R180 (Torsen) - USDM 2004-2005 Impreza WRX STi - UK/Europe/NZ Impreza WRX STi - JDM Legacy 3.0R Spec B 3.636 / 2.375 / 1.761 / 1.346 / 0.971 / 0.756 3.900FD - 3.54 R180 - USDM 2006 Impreza WRX STi 3.636 / 2.235 / 1.521 / 1.137 / 0.971 / 0.756 / 3.900FD - 3.54 R180 - USDM 2007-current Impreza WRX STi |

Personally I think Fuji has done an excellent job with all of this info! It was never confusing and if you do the appropriate research when doing a driveline swap you see that the 1.1:1 transfer gears net a 3.90:1 from the 3.54:1 rear diffs. You can't just assume you can mix and match rear diffs and transmissions at will.
That being said it would be beneficial to list those transmissions with the 1.1:1 transfer gears along with the rear differential final drives for those new to or just researching a driveline swaps! Last edited by manitou; 04-30-2013 at 11:08 PM. |

The only 1.1:1 trannys you have to be concerned about the 3.545FD rear diff is the '02-05 WRX 5spd and '06-current STi 6spd.
Check put the first page again if the change I did was enough. If i start listing all the differentials, that would have to be a section of its own. Kind of like the VLSD equipped models. Only certain models had them. VLSD (vulnerable limited slip differential) '00/01 2.5RS '00-09 Legacy 2.5GT '00-08 Forester with All weather package '02-07 WRX '00-04 Outback with All weather package '05-07 Outback, all models '08 Outback models other than base '09 Outback 2.5i SE or higher model NOTE: Outback models excluding H6, listing excluding '91 Legacy turbo since it's likely worn out already. |

A buddy of mine is selling a 555 ra gearbox, and I'm thinking about putting it in my 04 WRX. Thoughts?

I'm a subaru newbie. What's DCCD? I have an AWD celica stage rally car. Thinking of building a GD chassis. I hate the gearing in my car, so i'd like the best if i do a new build; without breaking the bank. I'm really looking at the 5 speed not the 6 speeds. I'm guessing they are a lot cheaper and i'll be running NA, so strength shouldnt be a huge issue. |

The STi RA 5spd runs a 4.444FD with the gearing it has. A few trannys here in the US runs that final drive. You can purchase it from Subaru $$$. Gear spacing and speed is similar to a '04 USDM STi 6spd without 6th gear.
The DCCD is a driver controlled locking center differential. It's basically like a clutch type LSD in which you can adjust lockup rate. It's initial torque split is 35:65 for the older GC8 STi RA 5spds. |

You want a long ratio gear set, not short. The less you have to shift, the better.
