Subaru Gear Ratios

I found this listed on another Subaru forum, but in a rather annoying format that was hard to read, so I spent the last few nights putting it all into tables.

This is a listing of most of the current Subaru transmissions, the gear ratios and final drives, and what speed you will be going in any gear at a given engine speed, broken down into 250 RPM increments. People converting to manual transmissions who have a choice of transmission (not just whatever you could find cheapest) may find this helpful in their selection process.

Re: Subaru Gear Ratios

And for those who need to get with the program and buy (or hell, just download) Word, here's the info in non-fancy table form.

MODELS DISPLAYED INCLUDE:
-JDM Legacy 2.0GT Spec B
-USDM Legacy 2.5i 5MT
-USDM Legacy 2.5GT 5MT & 5EAT
-USDM Outback 2.5XT 5MT
-USDM Forester 2.5XT 5MT
-JDM Forester STi 6MT w/ USDM WRX STi gear comparo
-USDM WRX 5MT

All speeds shown use the listed vehicle’s stock tire diameter. For the vehicles which have a different diameter tire than the SVX I have included a multiplier to convert to the SVX-correct speed.

For those without Word, and who don't want to buy it, and don't want to pirate it, install OpenOffice.org, it's what I use... http://www.openoffice.org/

Same here! They're very much alike. I use MS Office on my wife's computer for critical stuff that I have to send out that has to be 100% identical when it arrives - you never know... one time it'll miss something in the translation.

Re: Subaru Gear Ratios

For the JDM Spec.B do we multiply by .997 or the 97.7 that is in your MS word document?


Just pointing it out incase you hadn't noticed it

Re: Subaru Gear Ratios

If you're running stock sized tires you should, our tires have a diameter of 24.9 - 25", or about 97.7% of the Spec B's size.

Re: Subaru Gear Ratios

I have added it to the How To section under "Transmission"

However, I'm not sure the Word version is working out. I may need Chris to look at it. He is more savvy with this Microsoft crap.
