Great info. I only wish the thickness of the gears could have also been added but I guess their are really only two different 2nd gear and third gear sizes so it isn't a big deal. It would be good to have if you come by some take out gear sets cheap.

This is a wonderful resource.

If I wanted to try to get an OEM WRX 5th gear from 06 or 07 should I try my local dealer or is it more than likely they won't have it?

Hey guys, Great thread Fuji.

I was wondering what gearset I should get for my 05 WRX.
Its a daily driver, but at the same time, I'm going to be taking it to the track soon, and when when I do my daily driving Im going 60mph @ 3000 rpms. I dont really like to keep my RPMs over 3k because you burn up gas. So I was wondering what gearset has a nice get up and go, and has a decent top end speed. I'm also on a budget...kinda. Haha.

Im running 20lbs of boost if that helps at all.

Thanks

When you say you're at 3000RPM going 60mph.....why dont you shift into 5th?

As far as gears go, "budget" builds really wont offer any extra strength. The cheapest, most reliable way I could think to go is to find a used PPG gearbox in the classified section. When it comes to the 5-speeds, you really need to do it right the first time.

Even if you're running the stock 205/55/16's on a stock transmission (0.738 5th gear) and rear end (3.545 rear + 1:1.1 center = 3.90), 60mph should leave you just over 2200RPM. Either somethings wrong, or you have some upgraded gears in there already. With that kind of cruising speed, it almost sounds like you'd have the MFactory 1-5 gear set--that'd leave you right at 60mph at 3000RPM.

:facepalm:

Thats a little sketchy. Did you buy it from a dealership?

This might seem like a bit of a pain in the ass, but (assuming all is mechanically well) if you can post up the speed at....say....3000RPM in every gear, I might be able to help you figure out what you've got. Maybe you wont need an upgrade after all.

Might be easier to just ask him what he did to it, in that case. It'd be beneficial in the long run to know that car inside and out, so if something goes wrong you have some idea of where to start.

But sounds like he already has his gears and possibly the diffs done for his benefit........ I guess he doesn't have to worry about anything for the transmission at the moment.....

With that said and the above..... maybe swap tranny with someone with PPG?? The '07 STi 6spd or say a rebuilt 6spd with the "high speed/Legacy Spec B" ratios is a good tranny for what you seek. It drops the RPMs a tiny bit from what a normal WRX has.

Another option is PPG's with a '06/07 WRX, which runs a 3.700FD. This drops the rpms a bit, which will also give you the lower RPM in 5th on the hiway. The stock gearing can break so that's why I included PPG gears. Remember to swap the rear diff. Down side is that the longer ratios make driving with a 2.0L a bit of a dog.... not as preppy.

hey fuji great info.

wondering about 6 spds and the changes they've made.
so 04-06 sti usdm had a cooler right?
07 sti is new gear ratio and no cooler?
wondering the difference from 07usdm to jdm v7 and v8? Seeing alot of jdm trannies for sale, any problems with these as far as maintanence? can we get the gears and parts or are they similar to usdm? SInce you are using one maybe you could give us insight for jdm 6spd parts. Didnt see v8 jdm on your list.

whats different?

jdm v8 spec c vs regular jdm v8sti?

jdm v7 vs jdm v8?

using a 93 cable driven dash what works with that?
thanks for the help, the trannies the last part on my build, time to actually hook some of this power, 2 by legacy tranny against boost is extremely useless. and @ only 250 whp and trq. HAHA thanks for the help!

I guess this webpage shows a little bit when you look at the NOTEs
http://spda-online.ca/modules/tinyco...ite/tc_28.html


The first 6spds had the internal oil pump. '07 was when they took it off.
http://forums.nasioc.org/forums/show....php?t=1574301

The gears can be swaped since they are the same casing. Difference really from USDM to JDM is just the gear ratios like what you see listed on the first page of this thread. I could USE the newer style syncro cones etc in my Ver8 6spd. Also I could use better shift forks too.

JDM 6spds vary in DCCD or non DCCD. This is model specific. Models with STi badging usually always have DCCD as it is an STi feature. WRX RA Spec C will NOT have DCCD.. WRX RA STi Spec C will have DCCD. Impreza WRX STi has DCCD. Impreza WRX Spec C will not have DCCD. All the gearing is the same for Japan since the start of the 6spd.

With your cable driven cluster, you can take off the speedsensor on the tranny and swap your cable wire onto it. Remember the washer!

So it looks like a Trans upgrade is in my future for my 2002 WRX and now comes the fun part of picking which company to go with.

This will be for a weekend toy, so I would like something that is still comfortable running errands for the wife in, but can take 350-400 HP when I want to play.

So far I am looking at about $4K for a set-up from Andrewtech.

On Rallispec's website I saw they have RA/STi Gear sets for a much cheaper price. So will a gear set form Rallispec hold up to the power levels I have?

I realize that I will have to have the Rallispec set installed and that the Andrewtech box comes fully built. A friend of mine is a Subaru Mechanic so the install will be no problem.

So I guess what I am asking is will the Rallispec Set be enough or do I need to just go ahead and get an Andrewtech Box.

Thanks.

well..... give it a shot. If it doesn't hold well... then maybe I lied? Drive well and it should hold fine.
