Does anyone using evo 9 first gear with mfactory 4.3 final drive. Isn't 1st gear going to be too long? I have evo 9 1st gear and evo 8 rest gears and I am wondering if 4.3 final drive will make first gear too long or just fine. To my calculation says it will be exactly same long as like evo 8 1st gear with 4.11 final drive. Thanks!

 

Here is Stock, 4.08, 4.11, 4,31 for comparison of E9 and E8 1st gears


Stock FD E9 1st


Stock FD E8 1st


4.08 FD E9 1st


4.08 FD E8 1st


4.11 FD E9 1st


4.11 E8 1st


4.31 FD E9 1st


4.31 FD E8 1st

 

Perfect!!! But this is evo 8 1st gear correct? I will have evo 9 first gear.

 

I added E9 1st gear for a comparison of E8 vs. E9

 

Ohh you are right.. Thanks a lot!!!! I really appreciate that.

 

The taller final drives are fine if you have a stroker motor, or have a drag car that needs to be able to go 150+ in 4th. Otherwise, keep the stock FD.

Also, a few of us (including me) have experience the Factory FD being noisy.

 

Thanks a lot for response. It is 2.0L motor. I will do evo 9 first gear and keep the stock FD. I heard from a lot of people that Mfactory FD are noisy which I think will bother me a little. I was trying to have little longer gears because I am spinning tires on 1st and 2nd but I can always get some semi slick tires to calm it down a little. Thanks !!!

 

I had a 4.11 in a 2.3L and I hated it because I couldn't rev pass 8500 so I had a lower trap speed.

 

Boost by gear is your friend.

 

My car likes to get sideways. Just practice modulating the gas pedal. Changing the gearing isn't really a work around.

 

Once you start making over 600whp+ or have a responsive stroker engine Its nice to have a taller final drive to calm things down a bit. The Evo was geared for the Rally. Many of us are horsepower junkies so the stock gearing becomes an issue at a point.

Longer gearing with power is less drama /wheelhop etc. A better or smoother application of the power. A few examples would be most liter bikes after 2003 had 80-110mph first gears. Or super cars with 60-80mph first gears.
An good example would be the sequential evo. Its geared for 75mph in first. Its on a 245 drag radial but you can brake boost at 40mph/5000 rpm and it just rips . It doesn't dance around or wheelhop and brake parts. 4.0 60-130mph runs on crappy asphalt or the drag strip.

Of course, if you had a sticky tire, a slipper clutch and ideal conditions a shorter gear will accelerate harder then a longer one.

 

That is exactly how I felt when I ran 4.11's in my 2.4L IX RS 13 years ago. With 480 lb/ft I didn't really need more torque multiplication.
One of the best additions I had installed in that car.

 

I have the Evo 9 MR with a six speed and the stronger 6 speed gearset with the tallest final drive. I really like the few hundred rpm lower cruising speed I get going 75mph. I have no problems with 1st gear being too long, but the biggest thing I notice is on a road with say a speed limit of 40mph.

If the speedlimit is 40mph, with the stock 6 speed I would typically just cruise around going about 45mph in 6th. Now I use 5th gear until I can get going about 50mph or so, then I will use 6th. I have no problem getting away in 1st.
