nice. hows the drive after the final gear now? thanx

 

******* sweet man!! Those gears are gonna be sick!

 

do you have any more pictures of your sub setup?
Looks pretty sick!

 

Nice mods indeed Need

 

How much did you pay for the Final drive?

 

^i second this..inquiring minds wish to know

 

you guys can get the prices from japanparts.com

it's not the part thats expensive though its the shipping plus installation that makes it an impractical upgrade.

 

www.mazdaparts.com is a Japan parts dealer...Thew can get it for cheap by bringing orders in on a pallet shipping crate

 

I wonder if that 4.77 final drive is the $300 kia one.

it may be the same shape but won't hold up to the power...that is why it was mentioned people were cryo hardening them for higher load usage

 

very nice, please post more info on the ECU please.

 

nice buckets. BRIDE GIAS you baller! <<< jealous

 

how much is cryo treatment?

 

I can only see this being an issue from a launch with very sticky tires (on a relatively stock 8). The Kia produces 30lb-ft more torque, redlines just north of 6000rpm, and is about 300lbs heavier. That final drive undergoes pretty heavy stress in the Kia.

 

^ Also the Kia 4.778 gear is actually made by Mazda. I'm guessing that the FEED 4.778 if traced back is probably a Mazda 4.778 gear.

 

interesting, well then what is stopping us?

 

I was all for doing this until I looked at my shop manual and realized that this is not a good idea for "do it yourself" unless you've had some experience working with differentials.

Now it looks like installing it would probably cost me more than a new Final Drive.

 

there should be nothing stopping us! this is probably the most helpfully N/A Mod we can do to our cars

 

in a best motoring video there was a 400m comparison with a stock rx8 and a ms rx8 with 4.7 gearing in 400m meter race, there wasn't much difference as a matter of fact the ms rx8 clock in 15.1 where the stock on did 14.9. This was in wet roads though, but I doubt it's as powerful as a mod as you think it is . 4.44 to 4.7 is not a crazy amount of difference in terms of gearing.

 

1.075:1 difference. going from 3.73 to 4.11 on an F-body is 1.10:1, and one heck of a difference. 4.1 to 4.56 on an S2000 (1:11:1) is one heck of a difference as well. 1.075:1 will be very noticeable, imo. There's more to that stock vs MS 8 story, I'm thinking.

 

ITS ONE OF THE BEST THINGS I HAVE INSTAL, ITS MORE POWERFULL DRIVING.

 

I have no pic on mi car but this can help.
i have it with a HKS racing succion kit

 

its a Vibe audio exact 8" 300 rms 4homs power.
