BF F6/XR should be 86 series
Quote: M86 final drive units are fitted with 3.23 or 3.46
8.6" (220mm) diameter gear sets, with or without LSDs. M86 final drive units are fitted to all sedan vehicles powered by a V8 or turbo I6 engine. |

I hope yours is a manual and not an auto.
If its an auto, thats and awfully big f**k jump and would render first and second gear almost useless. Be a ripper off the line tho if it can get traction. |

it isnt for my car its a mates he has a ba series 1 with a series 2 tranny and a series 2 bf turbo diff with the ratio of 2.73 it picks up like a nugget due to the ratio used to run better with the series 1 diff with 3.45.
he has a spare straight axle diff off a series 2 ute (dunno the ratio) can he take the guts out of it and put it in the guts of the m86 irs just the gearing change or are they a complete different set up

arm79 i think you mean "i hope its an auto not a manual", the btr's have real tall 1st the manuals have the shortest 1st, with 4.11 diff gears would be lucky getting 40k's out of 1st in a manual the auto would get at least 65k's out of first

This man knows how it works. Only 2 boxes available on BF Turbos, and none of them are BTR's. |
