6 Speed swap

I had been reading stories about broken 5 speeds and now that I have 308 lb-ft of torque at the wheels and thinking about building more... so I put in a bid on E-bay. So I am soon to be the proud owner of a 2005 STi 6 speed transaxle, shifter, driveshaft, rear differential, rear driveshafts and various mounts and crossmembers. I did a search and didn't find anything here on the swap. I assume it will be the same as a swap into a Subaru. Anybody else here tried it yet or know any good links? I assume that I need a DCCD controller and a clutch at the very minimum. I have also read something about maybe needing front axles, but the articles were on older Subaru WRXs.

Re: 6 Speed swap

check www.nasioc.com out.....someone has definately done it there and most likely has a picture guide.  IIRC no one on this site has done this mod yet so you won't really find anything on it in here.  however eqlized_aero is gonna have to do it real soon and he knows how to mod his shit so you could try pming him.  thats all i got...i hope this works out and i want to see some pics.

That's going to be awesome.  First STI 6-speed Saabaru!  About how much is that going to run you?

Re: 6 Speed swap

That's awesome that you are going to get the 6-spd, but keep in mind that your current transmission is MUCH stronger in 1st and 2nd gears (the problem ones) than 2005 transmission, which is also MUCH stronger than 2002-2003 transmission in 1-3 gear.

Re: 6 Speed swap

Friend is having problems with his 04 STi trans.  Nothing big, just a synchro here or there  lol

Another friend just did a "JDM 6 speed" swap to his bug eye, but he also has a built motor and can take advantage of having a 6th gear.  I don't see a need for it personally..cool none the less though.

I thought about it though since I have so many friends into these Subarus that I could get my hands on it all at a good deal too...

You will enjoy it.  It also comes down to personal preference.  Some people wish the 6 was 5, and vice versa.

Re: 6 Speed swap

From AndrewTech

"Through research we have found the LGT gears to be the a substantial factory Subaru gear upgrade! They are not unbreakable as they are still stock gears, but are a SIGNIFICANT upgrade to the 04+ wrx1-2 and 02-03 wrx1-4 factory gears. "

I'm reasonably sure the 06+ use the same gearbox as the LGT.

Please post a reference.  I can't find anything stating that is true.

Re: 6 Speed swap

Hmmm...I take it back, the only real difference seems to be the taller final drive...3.7 vs 3.9.

If that's the case then, yeah the you want new gears for sure.

Re: 6 Speed swap

I would be happy with just a LGT 1st and 2nd gear swap.  The drivability feels awesome as I have taken a friend's '05 LGT for a spin.

Re: 6 Speed swap

So 06+ WRX/92x still has the same garbage as previous models?

I wouldn't call it "garbage".
05 trasmissions are fine.
If you don't drive like an idiot, it will be alright.

Re: 6 Speed swap

This is known is the R180 6 speed swap.

http://forums.nasioc.com/forums/showthr … R180+wagon

This was bookmarked for a while. I would love to have this done.

My mechanic did a complete 2005 STi swap into a 2005 WRX wagon. Complete with identical wiring harness and all the axles, hubs, trailing arms, rear suspension bits. Since you are at it go for the GC8 aluminum control arms that fit our wagons.

PM Stever on Nasioc he knows all about swaps.

Speaking of swaps ... 06's have an advantage over the 05's since they already have drive by wire setup. That means easy EJ2507 swap.

Re: 6 Speed swap

Thanks for the links.

It was $3250 plus tax & shipping (or I may drive down to S FL & pick it up). I didn't think that bid would win it but I guess the price is coming down now that there are more STis around. So it should end up being cheaper that PPG gears without the noise. There is the bonus of the lower final drive ratio also.

The 2006 has so much more torque than a 2005 but as I understand it, the gearsets are the same with the exception of the final drive ratio. From what I have read it is third gear that is the biggest problem - the teeth will shear right off.

I may look into a Torsen center diff if the DCCD harness, etc gets too expensive.

Re: 6 Speed swap

Congrats on the 6 speed. I almost bit the bullet on one about a month ago, but the deal seemed too good to be true.

Sounds like you've got about everything you need. There is someone on NASIOC that has built a DCCD controller for about $150. I believe he is using a STAMP chip and some software he developed. That was the route I was going to go. You can run the transmission with no DCCD controller attached, but I don't think anyone knows the longterm effects.

I just planned on a new ring and pinion in the r160 and then an automatic tranny driveshaft.

Personally if you're still on the stock clutch I wouldn't be too worried about the tranny yet. Even with a heavier clutch, it's all about how you drive. I've had plenty of 3rd gear blasts with no problem and I have far more torque than you and an upgraded clutch. Shoot.. john_matrix has about as much torque as you, and the last thing he is worried about is his tranny.

I would get a new clutch and flywheel and install them at the same time as the tranny swap.

Hopefully you got the 6MT clutch lever included in the deal.

It may be overkill, but I like things to be reliable. It appears that the clutch cross shaft is included as well as the clutch.

Re: 6 Speed swap

The parts came today. Does anyone know if the 06s had push or pull type clutch slave cylinders? The transmission came with the slave cylinder (push style), but I would prefer to use the one that came with the car if possible.

Re: 6 Speed swap

I believe '06 has a pull-type, but I may be wrong. Haven't we auto-x'd together before? I've got a black '05 with gold Rotas.
