I have an sti box in my rs lib, 4.44 final drive ratio , i would really like to put a dual range box in because the current one is useless pulling boat out of the water. Where as My old stock standard l series wagon pulled it out in low range no problems at all.
I'd like to keep the LSD so does anyone know if the 4.44 was made in dual range ? Or will I need to source a 4.11 with matching diff ?
Any advice much appreciated,
Cheers.

The close ratio 6 speed STi box should do it, just keep it in 1st longer.

^^^^What? Please explain? ^^^^:)

The dual range AWD boxes have 1.19:1 or 1.47:1 so if you want 1.59:1 you will need to read this

you will be able to do it but you must get the crown wheel machined so the 4.11 or 4.44 crown gear doesnt smash into the low range.

He said he had an STi box. All STi boxes are 6 speed, and have very close gearing. So his 1st gear is like a low range gear compared to our 1st gear.
Im saying he should be able to make it without a low range.

I think it was around 1999 or 2000 when the STi first got the 6 speed, before that they were 5 speeds like the WRX

If the gearbox has closer ratios, wouldnt that make first gear higher?

Sti's came out 5 speed in the GC Impreza (classic shape), they changed to 6 speed in the GD Impreza (bugeye shape) but either boxes will not be able to be fitted with Dual Range because the D/R box has a 2 piece input shaft and the Turbo boxes are a 1 piece. You'd be better off selling the STi box and buying a 4.11 D/R box and then do the L.Series Low Range conversion and fit 4.44 if you really need the extra-extra low range but IMO you'd be happy enough with 4.11 and L.Series Low Range.

This would be the easiest way to do it!

The 4.44 with L series low range would be awesome - but a lot of effort!

The six speed STi boxes generally have a taller first and a low 6th, great for racing.
If you use an L seires low range with 4.44 diff you have take a lot off the crownwheel teeth and I mean a lot.
With L series low range and the 4.11 you only need to take the corner off the crownwheel.
4.11 is the easiest, when
swapping bits.

Thanks for all the info,
So seems the way to go would be is to get a 4.11 gearbox plus matching diff and get l series low range gear fitted.
A couple a questions for anyone who can be bothered,
1. Using the 4.44 LSD diff is possible but a lot of work In doing so, is the 4.11 available in LSD?
2.the only thing I'm wanting low range for is at the boat ramp so How about 4.11 dr box unmodified without l series low range ?
Cheers

I'm pretty sure someone on the forum just bought a 4.11 LSD. Hydrowill maybe? Got it for a song too. If you can't find one there's info on how to change the centre over. Not that hard to do.

a gearbox out of an SF Forester has 4.11 final and a 1.447 low range which is the best low range available in an EJ box. Sounds like just what you need.

Yes I think so, they aren't that hard to find.

This is what I have in my SF Forester. Personally it is a nice box and setup but my biggest let down is power from the piss poor gutless 2.0l (soon to be changed as I've gone through 2 of them already) and open diffs.
With an EJ25 and rear plated LSD it'd go almost anywhere. The L-Series low range would be nice but with the 1.447.1 in the SF it isn't too bad, It certainly isn't on the list to be changed anytime soon if at all..

ok thanks heaps for the advice guys.
How about the 4.11 gearbox unmodified, without l series low range???
Any good?

2.0 litre forester boxes are good, reasonable low range.
BUT, Check the gear ratios (1-5) compared to what you have now and work out what revs you will be doing compared to current gear ratios.
And of course the speedo gear ratio.
If you are running forester size wheels, no problems, otherwise carefully do the maths before it causes headaches.

Supposedly the 2002 Subaru Outback has 4.44 final driver dual range. Is this really true or misinformation?

How easy is it to get the 4.11 D/Rs? Which years did they come in and was it normally the Foresters that received it?

I might have answered my own question in this thread on the 2nd question:) showthread.php?t=14247&highlight=4.11+dual+range

Information from Thread above ^^

"there definitely are - that's the box i'll be getting. the first series has the 4.11 (non turbos of course - turbos are single range). the 2.5L has the better gear ratios imo. every now and then one comes up on ebay"

"Yeah i know the early 2.0l Foresters had the 1.42:1 low range and the 3.9:1 final drive but i dont know weather that was for the entire life of that model. But definately all the 2.5s are 4.11 with 1.15 low"

"gen 3 RX manual had 4.11 dual range!!"

"Yeah i was just going to say the Gen 3 Outback had 4.11 dual range."

"Gearbox code and ratio GUIDE remember that alot of gearbox's have been rebuilt since they left the factory and may not contain the raitos stated."

The gen 1 Foresters have 4.11 duffs with the 1.447 low range. Pretty decent but let down by the piss pour 2.0l
