4EAT 4.11 Front diff into 5MT
I drive an 05 4EAT WRX, i just purchased a 02 WRX 5MT with blown second and plan on buying a LGT gearset rebuild kit for 02 WRX to put in.
My question is with having 4.11 final drives in the 4EAT and a 3.90 front diff in the 5MT is it possible to pull the 4EAT 4.11 and put it in the 5MT? i dont know yet if ill need a new Cluster shaft for the LGT kit or not (i would assume i would) IIRC LGT's final drive is 4.111 would that clustershaft mesh properly to a 4.11? I looked at the stickies and couldnt find what i was looking for. Excuse my ignorance. |

Only problem is you would have to also swap out the transfer gears on the tail end of the tranny. The 02-05 wrx 5 speed has a 1.1:1 transfer gear set just before the rear driveshaft. Which is why the rear diff is a 3.545 ratio and the front is a 3.90

but would i have to find a different driveshaft? i dont have any of the extension/tail housings or any of their guts so that would be fine.
youre saying i would have to get an LGT's transfer gears? |

The auto drive shaft is shorter than a manual one so you will have to find a manual drive shaft. |

I know i need another drive shaft. What cars used the 1:1 transfer gears? Legacy? So just get an LGT cluster shaft and transfer gears and i should be good?
