WITHOUT SOUNDING PRESUMPTUOUS

Pretty sure your info you have found on google isn't true, as the GF8 refers to the EJ20 turbo variant and these were not available with the dual range gearboxes. GF6 (EJ18 & EJ20 NA) were available with the dual range gearbox in the "Sportswagon" model.

I have a copy somewhere of the AUDM FSM for the gen1 (GC/GF) Impreza but since I moved from Kelmscott, I've not been able to locate any of my manuals.

As for the original poster (8 years ago

) the info you were chasing would have been 1:1.447 ratio

I always thought that presumptuous was your middle name

so this line Impreza "1st Gen GF8 1992-2000", should read Impreza "1st Gen GF6 1992-2000". I got the vin number and other information from a wreckers website, as for its accuracy NFI.

However a Subaru dealership has confirmed this box TY752XR6AB is 3.9 final range with 1:1.447 low range ratio.

I thought it was carmella?

Would never post info from a wreckers page.. asking for trouble there.

And I wouldn't have posted the ratio if it wasn't correct

So what vehicles do those transmissions belong to? I always thought it was only the late 90s 2L Impreza sportswagon that had the "good" low range.

Been half contemplating putting a diesel in my touring wagon project, but they only came with a single range 6 speed. Might need a bit of screwing around with gear or diff ratios, etc if going to put a petrol trans behind it.

US sites are useless for this kind of info. They barely got any dual range L series, let alone anything newer

They came out in the 1996 to 2000 Impreza "Sportswagon" hatch with the EJ18 and EJ20 (both 1.8 and 2.0 non turbo versions).

The EE20 would probably destroy the D/R box but if you treat it carefully, then I'd give it a go. You can also swap over to the diesel 6 speed later on (remembering the diesel 6 spd is not the same as the STi 6 spd)
