I have read up on the 4eat center diff mod... and was wondering if it would be the same scenario on a 05 legacy 2.5i?

I'm starting to notice a lot more torque to the front (especially on some quad trails yesterday afternoon) and was wondering how involved or if it was even possible.

Thanks,
Jake

Can you be a bit more specific?

The auto boxes usually have about a centre diff split of 90:10% F-R in normal use.

The manual centre diff is 50:50 under ideal conditions.

I do not know, but I expect that part of this is due to the diff itself, and part due to the programming of the ECU, which exercises some control over the power distribution for this diff, AFAIK.
 
Yes it will work. Works with all 4EAT from around 1998 to 2008 Subarus. Makes a huge difference too so im told by people who have it. It will lock the clutch pack to 50/50 split, but you shouldn't drive with it turned on on the road, only offroad.

If you do a search on here I think there is a thread that Kevin did. Otherwise google it and you will find it, the mod is pretty easy to do to.

I was curious as to what would happen with it turned on on road? both the axles shouldn't be locked because they are open diffs?

I guess I could see it causing premature wear on components if you can manage to get tires to spin off the line or if you managed to get binding from the front and rear axles

EDIT: nevermind, read up on the binding. understood. Trying to decide whether to try to sell her again and get a truck or continue onward with a sedan.

It will bind even with the open diffs. this will happens when you turn and will hurt your tyres aswell as add a great deal of wear to the clutch pack.

its the same with tunning any four wheel drive with the center locked it will bind up regardless of diffs. only if you were running on a sliperly surface such as snow, mud etc can you run the center locked

I dropped a front shaft on my old Landcruiser when I left it in 4WD/high range when leaving the dirt for the bitumen once.

It is caused by the front and rear axles turning at slightly different speeds.

My LC had a transfer case - i.e. no centre diff.

yes ive heard some horror stories with people leaving it 4wd
 
and - because you are bleeding volts to ground the resistors can get quite hot so leaving it on for a long period is not recommended.
