OMGHi2U sti/RA gears into RS transmission housing

did some searches on the subject, but couldn't find if this combination will work (well). i thought i read something a month or so ago about someone here doing it, so maybe ya'll can direct me to the thread if you remember it. it seems to be a much cheaper way of beefing up the transmission without getting a whole new transmission or KAAZ gears or whatever.....

thanks
cody


:edit: the reason i put this in this forum is cuz it's for my 01 rs that already has a ej20 in it.... thanks guys.

A Subaru mechanic buddy of mine says it can be done and there are STi gearsets made for this application. Rallispec.com has some. There are also a coupleother places that escape me at this point. I will need this same swap soon as I am in the same boat.

Well at wost a blow wrx tranny isnt giong to cost you much and rallispec kit will replace most of the parts.

Dave from rallispec has a thread on the ra gear set in the tranny forum.

Senomar: There are just subtle differences between the various 5MT transmissions, so the STi & STi RA gearsets can easily be fitted into your gearbox. It's been done numerous times.

yes Rallispec should have a set that is Kryo treated. It will go right in your RS tranny.

Fortunate for me i was able to get my hands on an RA gearbox for the same amount of money.

Ask Lachute Subaru as far as getting a used gearbox if you are goin to go that way. I have had nothing but good results from that tranny. And with the wrx motor the sweet spot will be right around 4K RPM. Great power feel from those gears, totally drifferent monster.

so you would suggest the RA gears over the STI? i was kinda leaning the other way, because i do tend to hit the highway quite a bit, and may appreciate the extra fuel economy in the pocketbook.... hmm...

thanks guys

dude don't listen to them, with your 4.11 final drive and turbo application, the STI not the STI-RA gearset is ideal for you to keep the torqueband linear....

I agree with you on the highway speeds....trust me do the STI gear ratio.

cody

P.S. do you have the STI gears installed?

senomar: Just to clarify, the Ver.6 STi gear ratios are very similar to those in your RS trans, so the gas mileage would be similar as well. The Ver.6 STi gears are, however, much beefier just like the Ver.6 STi RA gears.

Exactly, and yes I will be putting these gears into a RS Tranny next month by rallispec with the stainless steel shift fork, new synchros etc.

I see some people getting used STI Tranny, but then there are other costs involved such as new clutch, master and slave cylinder if they are the pull type etc...plus your final drive too!

I see it like this, for $2500 you will have a brand new tranny with STI gears that are wide, hardened and retain similar gas mileage plus hitting 60mph a lot sooner!

your choice, but to me it's definitely worth going through rallispec as they know what they are doing and what it will take to build you a solid tranny with all the right components.

I have done sooo much research in this, and this is the best route for a RS tranny in my opinion if you are on a moderate budget.

Default that sucks... but

i'm not quite sure i understand what you mean... are you saying if you got an RS tranny, you could do this and everything (gauge cluster included) would match up??? and if you got these gears for your current tranny, your gauges would be off..????


thanks

I think that the RS transmission will hand the power fine. I just finished putting about 340 miles on my WRS at VIR this weekend and all seems well. I was running it all the way to the limiter and then downshifting two gears at a time on the front straight. I was doing 13 shifts per lap and I did over 100 laps. My car has also been EUCTEKed too so there was significantly more load on the car.

Ultimately I would like to get a different gearset in the car but I'm in no rush to do it.
