A 3.9 ratio D/R 5sp out of a L series is the best low range you'll get.

The rear diff in your car has the ratio on a sticker on the back of it.

Or with a 8" or more lift you can use a older Nissan Navara transfer case and have dual low range.

If the sticker on your rear diff has worn away then undo the oil filler plug and count the number of teeth on your crown gear. 39 = 3.9:1, 37 = 3.7:1.

Cheers,

John

You could pull the 3.7 out of your busted box and put in a 3.9 out of similar box but the best bet is to go with an L series 5 speed or build a Liberty box in an L case

But then you lose 4x4, And a locked centre is better then a 4.11 diff imho

I can honestly say i have never not been able to get somewhere because the gearbox doesnt have a centre lock.

Well I can. But 4wding isn't always the same I guess. Some places are harder then others and some people prefer the easier stuff.

haha

dave's lib doesnt prefer "the easier stuff"

viscous LSDs seem to lock up better behind turbo motors though. more power to get them hot and locked up

I run a locked centre 4.11, its great.

Not saying he or anyone takes the easy way out. Just saying I used to follow my Brother in his 4runner with front and rear lockers with 35x12.5 MTZ's and that is not exactly the easy stuff. Theres no way my Brumby could do a lot of what his 4runner did with the 4x4 box (trust me I tried most things) and the AWD box made it harder.

I don't like using lots of rpm climbing up rocks and that, so I guess maybe thats why no locked centre didn't work well for me. Most of the time I used to keep my EJ22 under 2500rpm on the tough stuff.

I have bits of an old Liberty box, but my 5sp L boxes have plans so can't help you sorry.

change of plans for now... just puttin in my spare 4sp 3.700 box...
but still lookin for an EA box but single range 4wd/AWD to put in newer awd setup on my old 76 sedan...

I dont have to flog the engine to get it to go where i want it to go as i know how to drive with what i have so it all works. in short the lack of a locking centre is not a big issue with a Subaru,so get you hand off it Phizinza!!

yeh its not about tryin to go through it or up it as fast as you can its about working out the most effective way and taking it...

thats 4wding... otherwise its just a case of "i dont know how to control my car so i'll just floor it through the biggest rutts i can find and think i'm tuff if i make it"...

ok so finally got my 2nd box in, while i was at it i replace the 2 inner cv boots that were split (got pinched inside the cup at full angle... they were crappy stiff boots anyways, they are now the nice flexible replacements...

next will be to pull the other one apart and see what went on in there lol...
