6MT's

[funkytown]

So its been covered in round about ways before.. for those interested in doing the 5MT to 6MT swap...

Is there a massive difference (Variance)in the 6 speeds? i know some come with dccd and some dont, but in terms of front diffs and gearing? are they much the same?

Wondering about rear diffs as well - coz most packages come with them now, is there variance in those

What are the "ones to get"? And how do the rear/front diffs compare to those in the 5MTs?

This is coming from a v3 with an open front and some crap factory lsd in the rear.

using the GB links it seems they either come in these flavors

front diff

Helical LSD

A.P Suretrack

(or open)

center

35:65 dccd

45:55 dccd

viscous

rear

I cant find what they have in the rear

Can someone order the above in best worst?

Should have everything you need to know...

6 speeds out of the impreza's have basically all the same gear ratios

v7-v9 are all 3.9 front and 3.9 rear diffs

v10 is 3.9 front and 3.545 rear diff ( the centre diff has drop down output gears, changing the ratio)

the earlier 6 speeds (v7 and V8) superceed their synchros to the later v9/v10 units. so if your synchros in your v7 or v8 need replacing you need to replace them with the gears (according to Fuji Heavy Industries).

also the front inner cv joints are different. V7/V8 are setup like the gc8's and most other subarus in which there is a male shaft permanently fitted inside the the front diff housing and the inner cv joint slides over it, while the V9/v10 has this shaft (also known as a spindle shaft) built into the inner cv joint. it is however easy enough to convert to v7/v8 if you were wanting to use one in a gc8 for example

the centre diffs either come in dccd form or viscous form.

same for the front diffs

also the spec c (and some optioned STI's) had external gearbox oil coolers. this is just a 2 piece pipe which bolts to the side of the box (which leads off to a oil cooler sitting in the radiator) instead of the 1 piece pipe which plumbs back into the casing

you need to run the numbers of the gearbox if you find one.

i have the full list of gearbox codes with specs and model applications which i can run through if you find a box
