Have you guys done a transmission swap before? What method is your recommendation?
Put an 2009 Outback XT trans and rear diff in my turbo Crosstrek (XV). Used the GRB WRX clutch and flywheel then upgraded a bunch of other little parts while I was in there: - Fork - Pivot ball - SS clutch line - Bushings - Braces - Etc. Driveshaft, axles and everything else bolted right up
snow ball effect indeed. Replacing my rear subframe and t frame due to rust. Drained my rear diff and chunks of metal coming out. My rear knuckle assembly and axles are just as rotted. Might aswell do full 6 speed conversion with sti hubs aswell. This video came in clutch. Thanks guys
Talk about coming full circle --I still remember when I picked up my 6-speed transmission from you guys 3 years ago. Fun fact, it was actually a Forester STi 6-speed with the aforementioned longer gear ratios, which is very much appreciated when hooning on the countryside roads of Aomori haha. That along with the EJ207-swap y'all did for me are hands-down my favorite mods on the car. Thanks to you guys, I'm manifesting my OEM+ goals one step at a time
We appreciate you man! We have been supper blessed with great people like yourself!
JUST FOUND YOUR CHANNEL !! SO HAPPY I DID !! IVE GOT A 04 FORESTER, 11 STI WRX HATCH AND A NEW VB WRX...WOULD LOVE TO HEAR ABOUT WHAT JAPANESE MARKET IS DOING WITH THE FA24DIT AND THE VB CHASSIS !!!
I love this channel, very informative and well done every time. Great job guys!!👍🏼
Glad you enjoy it!
Keep up the good work long time friends!
Thanks for watching!
Nick! Hey man, you’re tuning in? That’s so cool, hope you and the family are doing well.
@@OkiSubies we are doing good, and finally getting into a rhythm with the new addition the family. It’s cool to see how far y’all gotten with “the yard”.
Nice job
Thank you!
Hell yeah!! Only having to buy a six speed and a rear diff with a shaft❤
Makes life so much easier!
This a beauti right here. #subienation
Awesome video guys! Just had a question, have an 07 STI trans and Diff, with 04 STI Drive shafts, will I be able to use the V6 STI type RA R180 hubs with this setup?
Thank you! Yes the rears should work as long as they were from a 5x100 setup.
@@OkiSubies absolute legends. Keep up the awesome videos!
I presume the bigger calliper snipers will be the ones to go for, for WZ?
Dope video! Question i have a 98 gc8 wrx sti type r. Which year transmission is that? Is there a specific year tranny to get so thats its all plug and play? Thank you!
It would have to be the first generation blobeye sti (5x100) and it would bolt up as long as yours also has DCCD and a R180 diff. The 5x114.3 Blobeye would still work but you would have to do front axles also
Thank you!!!
I have a question. I swapped me 2005 wrx ej205 to ej20 jdm motor. I noticed it haves more hoses and connections with wire harness then the ej205. I’m super lost in the swap, I’m not sure what to cover and what not to cover, I got lost on connections too
What ej20 jdm motor is it?
Could you do a video on a spec b swap
Hey guys 👋 I just recently found your channel and im so glad I have 😊 I was wondering if this 6 speed swap would work the exact same on my V4 GC8 STI Type RA 555 VLimited 🤔 I've also been considering doing the merge swap from my EJ20K to either a usdm 205 or 207 and running a 6 speed DCCD with a 3.90 final drive instead of my 5 speed DCCD with the 4.44 final drive. My current transmission is SUPER fun in the city 😄 but BRUTAL on long highway drives 😔 Lastly have you guys considered selling your merge harnesses already complete. Especially one for my car lol 😆 That would help me out GREATLY if you did 😅
Thanks for watching! Do you have the rear 2 pots and R180 diff setup? If you do then it should be the same method. The 4.44 final drive in the Type RA’s are super fun but you are definitely right about the top end speed. We have considered selling them but getting GD harness are starting to get harder to find so we decided not to but we would be more than glad to assist you in your project🙂
@OkiSubies I do 🥳 Do you guys source out your own 205 or 207 motors with the full wiring harnesses?? 🤔 If so have you ever considered selling the complete package?? I live in Vancouver BC and the only 205 or 207 motors I can ever find are USDM which I'm assuming will be the same but finding the complete harnesses is IMPOSSIBLE 😩
@@Silver_Back81 We get engines and harnesses from part out cars, Mainland Japan, junkyards, Yahoo auctions and any other way we can get our hands on them lol. The good news is the harnesses can be used from even the JDM ej205’s because the wiring for the most part is the same as the STI. Unfortunately shipping something like that can be quite expensive and we aren’t sure how to go about that. Getting harness and heads shipped is a little more doable and would be a good option if you are planning to build the motor. Or just get the harness merged from us and source an EJ207. So many options lol😅
@OkiSubies Sweet 😁👍 One option I was looking at is to buy a forged USDM 205 short block and putting my EJ20K heads on it but I can't determine if that's possible. I'm assuming the 205 sensors on the block are different than my EJ20K. I also believe that the combustion chamber of my heads is smaller than the 205 and I would need to run a specific thicker head gasket. So after watching your swap videos it looks like it makes more sense to just run a complete 205 engine and use your merge harness instead 😅
@@Silver_Back81 you are doing some great research man! That is a very good option! Especially considering they have plug and play options for aftermarket ECU’s like Haltech. We just helped a customer do something very similar to his Type R! We bought a GRB STI short block and he put the ej20k heads with an HKS 1.2mm head gasket and tuned on a Haltech ECU. He also put the twin scroll vf37 on it and the car was extremely fun and responsive. You could technically even do a hybrid build and put a 2.5L short block on your ej20k heads, you would need to get the heads chamber matched but then you would have a torque monster lol
i have a v4 type R with a ej20k engine. if i decide to do the 02 jdm sti transmission, will i need to change the sensors?
You would need to put your speed sensor in the 02 transmission. Depending on what month in 2002 would determine if it has DCCD though. If you have dccd I would try and get a dccd 6 speed also.
additional question, can I use the 6speed trans, driveshaft, rear diff from a 6 speed legacy with dccd on a bl5 legacy?
@@malxsox791 Legacy 6 speed will bolt up in a Legacy yes. Rear axles are pretty important in that swap. Don’t think any Legacy came with DCCD though
Hi, I have the same v5 type ra and want to get the identical transmission with DCCD. Is the code Ty856wb1ba. If not can you please tell me?
Yes that is the bugeye Type RA so it has DCCD and female axles. Unfortunately I am not 100% sure on the transmission code we used but if it has dccd and have the stubs for the female axles in the transmission it will work. I want to say it was B3KA but here is more than one that works, here is the link with the different codes. www.rallispec.com/downloads/Transmission%20ID%20Chart_Public.pdf
@@OkiSubiesthank you so much. I am just trying to source a DCCD 6 speed trans that uses the female axles so I can direct fit it just like you did
the roof vent is only rated at 80kph during opening , its undamped and will fly open and damage the latch. once its open it can hang on even at over 200kph. ive tested it.
With it being rally inspired we wish that was the case but unfortunately that is not true. The Japanese writing on the lid literally says to keep the lid closed while going 80km or higher. We have had more than one customer not know about that and it break when running it while open. I am glad yours hasn’t been damaged while running it while it is open though.
@@OkiSubies there seems to be a misconception. it will only rip the latch or damage it if you open at speeds over 80kph... due to the sudden rush of air hitting the half opened hatch. if you open them at lower speeds before 80kph, they will hang on just fine even at higher speeds . I tune plenty of group N Subarus with these vents and crews run them at quite high speeds never seen a failure when properly used. It’s been a topic in GC8 and spec C forums for years and that’s was the general consensus.
@@kUNCHRIS I hear you loud and clear but this isn’t a misconception, the Japanese written on the bottom and our experience says other wise. I have seen multiple GDB Spec C’s and GC8 V limiteds break by simply driving at high speeds not opening them. I totally understand where you are coming from but with these cars and plastic getting older, the need to follow the directions written on the vents will be increasingly necessary.
really wanna 6 speed swap my gc8 too
It is an awesome change. Reliability and the gears are shorter so it is also performance upgrade!
then 6speed twinplate clutch can drop into 5speed?
Sorry we haven’t tried it the other way around😅
I have a 95 GC8. It has no stickers because it has been resprayed. It has that roof scoop and a few signs of a type Ra. What other way can I know it's type Ra?
Really depends on if it is the STI or WRX but the best way is checking the vin plate.
@@OkiSubies it is a GC8C4DD engine is a EJ20GD TRANSMISSION IS TY752VB4CA. Am new to Subaru so it's a bit difficult to understand them 😅. Hope that information will help me understand what model it is.
@@kasimbamunthali952 haha well that should have been obvious for you man!! That is a DCCD 5 speed so yes sir, you definitely have an RA if that is what is on your vin plate.
@@OkiSubies 😅 thank you. As stated I am new to Subaru. Your pdf of the transmission has also helped a lot. So if I want to switch to a 6 speed transmission, do I get any Subaru Impreza transmission or I get the RA 6 speed transmission only?
@@OkiSubies it's not for racing it is for daily driving.
hi guys, but this is not the TYPE RA STI V LIMITED, Because the speedo isn't blue and engine bay is white, that's mean this is a TYPE RA STI
Oh wow might be right! We thought that the RA STI’s didn’t come with power windows unless it was a v limited so we didn’t think to much about it.
@@OkiSubies maybe this car frankenstein, it has long life, doors could be swap't out from different car. but for sure that is not the type ra sti v limited cause they come only in 74f sonic blue mica to my knowledge. thank to your attention🙂
19:19 must’ve turned 5pm
😂😂😂you are correct!
