Default can someone confirm the ratios of the 05 sti 6 speed?

am looking at importing one of these boxes from over there complete with dccd.

I am told that they do under 3k rpm at 70mph which is roughly what i am looking for.

Am hoping someone out there can confirm this, or even better, if you have the actual ratios, it would be a big help!

thanks in advance.

Carlos.

mbiker the ratio's you just named are the USDM ratio's. Carlos said he was going to be importing one so I'm assuming he meant JDM
Here is the JDM ratio's.
1st: 3.636
2nd: 2.375
3rd: 1.761
4th: 1.346
5th: 1.062
6th: 0.842

70mph in 6th should be about 3100 RPM if I remember right from last time I was in my car.

Since Carlos said "over there" I assumed he was importing a USDM tranny, much like guys import our short block. Good info nontheless.

thanks guys, you are spot on.

I am in fact in the UK and was going to bring in a USDM 6MT from the states.

To set things straight, I need a gearbox which might be able to handle 500+lbft from 3000rpm. Trouble is with that much torque I want the gears to be spread over >200mph (with a 7500rpm redline). Your 6 speed seems to have better gearing than the 6 speed from japan and the UK (longer 5th and 6th only) but is still shorter than my 5 speed which is of course spread over only 5 gears, hence using the torque more which is what I wanted to do.

I was told the 05 sti had longer gears than previous models, but until now was not aware of the ratios

The one I am really keen to see is the forester sti as I believe 8k rpm in 6th in that is around 217mph. I appreciate that I won't get anywhere near there but the top speed of the box is a good indication of how well it is spread over the gears.

My current fifth is a 0.738 with a 3.9 final drive, so is longer, but there is no guarantee that it can take it. I know the same can be said for the 6mt but at least the gears are that much bigger, as is the casing, and it is still a pleasant synchro box.

But if I have a theoretical 200mph, I would rather that it were spread over 5 gears than 6, else with 500lbft I will be forever reaching for the next gear.

Info is very much appreciate, but does anyone know how it compares the the forester six speed?

I suspect that may be the better bet.
