Manual Transmission Gear Ratio

The STI 6 speed has a top gear ratio of .76, while the SVX auto top ratio is .64. Is there a manual which has a top ratio closer to the .64 or any after market gear kits which would have it? When doing highway miles I want to keep the RPM down when cruising.

Keep also in mind that any manual tranny will have a lower final gear ratio too...so even if you find a tranny with a .64 high gear, it will still be turning more RPMs than the Auto in the SVX.

The JDM Forester STi trans has a 0.707 top gear. Short of getting a custom gear cut, that's about as good as you're going to get.

Perhaps you shouldn't get a 6mt??? Me thinks a 4.44 is more suitable from what you have indicated thus far.

the best 6mt for a cruising ratio is the JDM forester... since they are not easily found I believe the USDM 6mt has a .72 as listed which is very nice... I get 21mpg in my silver with the .86(i think) JDM sti trans I have and thats with a little dipping on the throttle here and then too... So a stock SVX should get closer to 25-28mpg. With the USDM trans it should be right around 30mpg w/ a good running car.

That would be an Auto no? This will be my 4th Tranny. No Auto's. Plus I do like to play the gears on the twisties.

Ah okay, yeah manual tranny is just so fun... I just love driving my car... if you do go for 6mt I would recommend to be very careful around E-bay... when I was doing my initial searches I found that about half of the offers on e-bay were scams. Also do remember you are looking at roughly $5,500+ for the entire swap.

Good luck
