GusGus's Tranny Swap
 

Oh no.

What happened? Nice that you can get the swap.

Swerved to miss somebody that was coming into me, and over corrected and spun out. Thus resulting in jumping a 5" curb and smacking a bunch of stuff on the curb, then flying into oncoming traffic backwards.. Now I have a whining sound when I drive coming from the tranny/driveline. It's just a good excuse to motivate me to do the swap. I think it was fate as well. :lol:

Just making sure you're up on what else it takes for this swap...

You know you'll need 5x100 '04 STi rear hubs to replace the 5x114.3 hubs that are in that kit.

Plus you'll need some 5x100 gravel rally rotors to go with your existing 2-pot rear calipers (P/N RSTR-2634 from RalliSpec: http://www.rallispec.com/prod_brake.htm, or you should be able to get them direct from Subaru, but I don't know their FHI part number off hand). And that's assuming the TR 2-pot rears are the same as the gravel spec 2-pot rears that fit on the R180 compatible rear spindles (I'm pretty sure they are).

Alternatively, I'm not sure what the rear-end ratio is on the '06 TR, I think it's a 3.90. Older WRX's had 3.545's and older STi's had 3.90's... but I think in '06 they switched... so if you can find a 3.545 WRX R160 rear-end from an '02-'05 WRX, you can forgo all the rear brake/spindle/hub swap stuff and just keep an R160 in the back. Someone correct me about the TR's rear-end... if it's a 3.545 then it should work with the '06 6MT.

I'd be more worried that you've got wheels/suspension/wheel bearings damaged than the gearbox. Though you could have killed the rear-end and gearbox as well... but it's unlikely IMO that you'd break the tranny without also breaking those other parts along the way.

Im sure as we are going, we'll find out what else is wrong if anything else is.. I mean, it drove away and down the street.. but i'll just have to wait and find out..

Thanks for posting all that stuff up Sperry. It was a big help. Looks like I've got some research to do before I do this. Im still doing the swap though. :P

Damn gusgus, some luck you have with that car:lol:... w00t now I'm not the only person who smashes into curbs! Haha good luck man

At least I didnt take out my nice new wheel though in the process! :P

Are you going to stay 5x100?

Thanks kevin. I was looking for those!

So you're saying that as long as I get the R160 in the back, I can bypass at the other small stuff and call it a day? If that's the case, I'll just try and find one..

Maybe you should just take it back to stock and stick to riding a bike.

Well, I don't know about the front axles. I don't know if there's a stub axle or not on the WRX gearbox. There isn't one on the '06-6MT. So you may need to swap in the STi axles up front.

In the rear, if you keep your R160, you won't need to fuss with rear axles, spindles, hubs, brakes, etc. If the '06 TR WRX still used the 3.545 rear LSD like the pre-'06 WRXs did, then you already have what you need back there to work with the '06 6MT. That is assuming you know for sure the 6MT you're getting is from '06. If it's an '04 or '05 you'll need a 3.90 rear end. You really need the number off the gearbox in order to cross reference the year to be sure. Mismatching the rear-end ratio will demolish the center diff.

^^^ All this is why I chose to sell my car and buy an STi vs swapping drivetrain LOL. I believe the 06 wrx halfshafts are stubs...but its been a while since I looked.

IIRC 04+ is no stubs.

...and I'm so never doing this upgrade.

Pansy! :P

Maybe, but at least I won't be broke with a FrankenSuby. ;)

No offense to those of you that are broke and have a FrankenSuby. :lol:

My god.. what am I getting myself into.. haha Oh well. It'll be worth it when i shift into 6th :)

Can you get that fast when you're sliding sideways?

You mean spinning? im sure it could be arranged..

:lol:

None taken






wimp

Dbl phone post

$24k+ and counting in my 02 frankenSuby wagon :eek:
I thought it would have been no more than 15 when I started
and I am definitely working on being broke lol.

Well I PM'd Fuji K on NASIOC. He's the guy who wrote up the whole gear ratio thread. and here is what he replied to me.

"The '06 STi tranny would require to run the 3.545 rear diff. This diff can be found on all '02-05 WRX 5spd manual.


Fuji"

So does anybody have one??

I will give you mine in trade for your brembos.

Suck my left nut joel. hah ..............no homo.

Hmmm... tempting. but no.

Like I said in the other thread, I've got a non-LSD 3.545. You can swap the LSD carrier from your 3.90 into it and be all set. It's a little messy, but the swap takes well under 30 minutes... at least Cory and I were down to 30 minutes to do the swap on my SVX and that included taking the diff off the car and reinstalling it.

You could even sell the open 3.90 you'll be left with to some poor schmo that's got an older WRX who's doing a 6MT swap who can swap in his 3.545 LSD carrier. 'Course, if you can find someone doing a 6MT swap into a bugeye or something, just trade them diffs straight up.

Sounds good to me. I'll take it. That way i can start tearing the car apart now. Then when my clutch arrives.. Everything will be ready to just put the tranny on. :)

haha well that's you and cory. It may take me about....eternity.
:picard:

I just double checked the part number on the tranny.. it's an 05.. but im assuming that i'd still need the same diff and that nothing changes? I hope..

If it's an '05, I think it will work directly with the diff that's already on your car. See if you can confirm the rear diff on the '06 TR is a 3.90, cause that's what you need.

I have a 3.70FD... That's stupid..

Ouch. Didn't see that coming. WTF?

Yea. that's what I said.. I dont know what the F to do now. haha

EDIT: Nevermind, I need a 3.90FD again.. Back to square 1.

If anybody has a rear diff they want to sell out of the following car's please contact me asap!

NOTE: REAR DIFF Final drives are tranny specific
'98-01 5spd Impreza L/Sport wagon 5spd, or 5spd 95-99 Legacy 2.2L models
02-07 5spd 3.90 Impreza TS/RS wagon/outback sport
06-07 Auto WRX 3.90 VLSD

Austin, I'm pretty sure I have a 3.90 FD R160 at home. If you want to take it down and see if it is, you can pick it up at my house tonight or here at the shop tomorrow. It's in good shape and I know it's usable, I'm just not 100% sure it's 3.90 and not 4.11.

Could you possibly get me the part number off it tonight, and if it is what I need I can pick it up from the shop tomorrow before I leave tomorrow for sac.

Which vehicle is it off of?

It's from a 2000 OBS 4EAT, if it's stil the one I'm thinking of. I'll check it for part numbers tonight.

Ok thanks
