Post them up if you have them. I don't mind helping those who have already made an attempt to learn/research, as it looks you have. It's the posts like "Y0, I got a WRX an I am swapping a 6 speed. Wat do I need?" that get annoying and tiring.

Something something help those who help themselves comes to mind.

I'm still confused about kiyanichenko's question on page 4. Im doing this swap right after Christmas so I want to make sure I have everything ready. For a 04 sti speed swap into a bugeye Wrx I just have to get what kiyanichenko listed

04 sti 6speed
04 r180 diff
04 sti driveshaft
04 sti axles
aftermarket dccd
clutch fork,disc,pressure plate, flywheel, and slave cylinder

plus 04 sti rear hubs/knuckles right? Im getting the brembos and rotors front and rear off a 04 sti. I've been told that for the front I could just put the brembo calipers and rotors on but the rear is the reason I need the hubs and knuckles. Is this right? and wouldn't I just also need the rear sti axles if that's the case or would I have to get the fronts too.

If I wanted to swap an 04 transmission into my 2000 RS, and didn't want to deal with swapping hubs, is there any way I can use the R180? Or do I need to find an auto drive shaft and R160?

I think I got this right, but someone correct me if I'm wrong.
When swapping 05+ STI drivetrain into a gc8 with sti sway bars, I need:
Front: STI lower control arm, STI front endlinks, and STI sway bar.
Rear: STI adjustable lateral links (because stock sti links are too long and give crazy cambers, i think?), STI rear endlinks, and STI rear sway bar. Also STI rear subframe but you need it either way with STI rear diff, I believe.

With STI sway bars, do the front or rear become wider? If so, how much?

Can gc8 with 05+ STI drivetrain swap and stock gc8 lateral links use GD WRX rear sway bars?

Hey Guys, I don't want to piss anyone off but I've been reading all day trying to figure out what I have to do to fix my problem. Today I blew 3rd gear in my 07 WRX Limited Wagon. I talked to a lot of guys today and decided to go to the 6 speed swap. I bought the above parts from the vendor for sale form and asked the vendor will this bolt up to my WRX and I keep my rims and brakes. He said yes but after reading thru these threads and reading so much about numbers matching or different parts from different years working that I"m confused. I didn't ask the vendor what year the Ver.7 tranny is just ask will it work with what I have. So do you think I can make these parts work with what I have. Thanks for your help and I have been reading post trying to figure out what I need to do.

well.. i'll tell you what. you have a V7 sti trans? so that would be a 2003 2004. so what you need to make this work is the rear hubs from a 2004 sti(5x100). a R180 rear diff from a 03(jdm V7 or V8) or 04 - 05 usdm. rear axles from any Sti. some are longer but it doesn't really affect anything. and an Sti driveshaft or automatic (4eat) driveshaft. rear 2 pot brakes that you probably already have..(lucky #$%^#$%) you can reuse your 5speed clutch if you use the 6 speed clutch fork. good luck with your swap. V7 don;t have dccd if i recall but if yours has one get a DCCDpro.com controller they are the bomb.. apparently.

^ I agree with all of this except the driveshaft point. If You were using an r160 with the right ratio (for instance, the 02-03 usdm r160 matches the 06-07 sti transmission) you would need the 4eat because the transmission is longer than the 5 speed, but if you are swapping both the transmission and the rear diff, you need the sti driveshaft, as the yolk on the r180 is different than the one used for the r160, which is on the 4eats and the 5speed driveshafts.

In regards to the differential matching game that comes with the 6speed swap, heres the nitty gritty: The gear ratio in your rear diff needs to be compatible with the gear ratio in the other diffs. This is important for everything to mesh correctly.

Now, there are a couple of ways to accomplish this. The easiest is to do a full swap, and get an r180 from the same year STi, thus eliminating the problem. This, however, is expensive. There is a cheaper way. Subaru, in their infinite knowledge, decided that the STi and the WRX should always have different ratios, but in doing this, when they changed to the 06-07 models, they actually made the STi's ratio the SAME as the 02-03 (possibly 04-05 as well, but I can not seem to verify those years) WRXs. This means the r160s in those cars are set to compatible ratios with the 06-07 6 speeds.

If you still want to keep your r160 in the later WRXs, you can either swap it with an 02-03 (possibly 04-05) OR you can change out the gearing inside the diff to match whatever transmission you can get your hands on. That gets tricky, but allows you to do things like make your car have a final drive of 4.44 or something crazy like they do in Australia.

Here is a site that lists some of the ratios available (note the 3.54 in the Ver. 7+ STis matches the 3.54 listed in the r160 list. That is the magic number for the 02-03 diffs. It is a shame he does list the MY or ver number for all the ratios though.)

For the 6 speed out of an 06 swap into a 02 you need the following.

Slave cylinder out of what year STi?

STi driveshaft out of what year STi?

Axle stubs from an 04 Sti with correct circlip and seal

DCCD controller, Apparently you need the ECU from what year STi to make it functional?

Shifter linkage and boot from what year STi?

I'm literally doing this next week hopefully so any help is appreciated

You do not need a slave cylinder unless you want one. The WRX one works just fine. You need either a 4eat driveshaft out of any impreza/WRX 01-07 or an sti driveshaft that has the correct yolk on it (you can purchase a yolk at your dealership, but the 4eat one has the correct one on it). For the controller you do not need an ECU swap unless you are swapping the entire wiring harness (which is ridiculous), just get a Spyder controller or a neetronics one or something. The piggyback onto your stock stuff and have a similar amount of control. YOu can actually skip the controller all together if you want, it'll make the DCCD completely open at a 60/40 read/front split and won't hurt anything. The shifter linkages are all the same but you will obviously need a 6 speed shifter to accommodate the reverse lock out ring. The boot has to come out of an 04 sti as that is the only model that has the same interior as the 02-03 wrxs

What about the pressure plate, flywheel, clutch, throw out bearing? That should cover everything

All the stuff you listed can come straight off your WRX. The only difference between the WRX clutch/flywheel and the sti is the fact that the sti has a bigger diameter. If you havnt purchased a new one already get the sti spec bc in this case bigger is better, but not necessary. Just make sure you have the sti clutch fork, or it won't work.

Would the 06 STi clutch/pressure plate fit on my 02 wrx flywheel if not what year STi do you need a clutch out of if you want to do it? And what axle seals do you use with the STi stubs. Part numbers would be appreciated.

No it won't fit. The flywheel is a larger diameter in the STi as well to accommodate the larger clutch. All STi's are this way. I do remember now that the 02-05 WRX set ups will work with the 6 speed, something to do with being a push (or pull) setup while the 06-07 is a pull (or push) setup, I can't remember which is which, jut that they are opposite, and all STi's (07 or earlier of course) match the 02-05 WRX style.

Anyway, to answer your question again, you need either an all 02-05 WRX clutch/pressure plate/flywheel or all 04-07 STi clutch/Pressure plate/flywheel. Besides, if you are buying a new clutch you should buy a new flywheel. The clutch plate and the flywheel have to mold into each other so it's much better to have new surfaces on both items instead of a machined surface on the flywheel. Gruppe-S makes nice lightweight flywheels at reasonable prices, along with exedy clutch kits. Go there.

Yea thats my question, Were those average prices on finding used parts on the forum? Or do you have some hidden gem of a vendor that i would love to know about lol jk Im thinking about piecing together the swap on my 02 Wrx now I can get a rebuild Sti tranny with 200 miles on it for 3700 shipped so if you have any good advice to find all the supporting mods cheap pm me please... Thank you for the sweet thread!!
