How To STI Swap Your WRX

[@StreetInspired1]

Everything you will need to do the swap can be found in the description of the video, however heres some things I forgot to mention in the video: You will need a Re-Tune to account for the gear ratio change. You will need to bleed the new slave cylinder. All you need is someone to pump the clutch pedal for a few times, hold it to the floor and Crack open the 8mm bleeder nipple on the cylinder for a second and continue this process until clear fluid with no air bubbles comes out. Exhaust Hanger is on the wrong side on the sti transmission and there's no mount on the opposite side so you'll have to fab up your own exhaust Hanger mount or run without it. Transmission carrier is different but interchangeable. You'll need to re,-use your wrx one or your exhaust will rattle on it. Youll need the Sti dust shield, no dust shield, or bend your wrx shield (I bent mine and have no issues)

[@chasecenteno]

Super informative video! Thanks for the breakdown. Quick question, I heard of issues of the display cluster reading the incorrect gear even after a retune. For instance I heard 5th gear will still register as fourth gear on the cluster. Have you ran into this issue? Was the tune able to fix the display? I appreciate the insight!

[@StreetInspired1]

12:00 this gives me flashbacks to the nightmare of a time I had trying to do the same thing with my car (05 WRX -> 04 JDM STI). Trying to maneuver around that massive STI transmission with little to no working room due to doing the swap on jack stands was horrible. I swear my back hurt for a week once I was done with everything from rolling around on the floor. The rear sub frame wasn't any better. I balanced the whole thing on a jack as I tried to bolt everything into place.

[@StreetInspired1]

That has to be the worst part of this swap! A lift with a transmission jack would've been great haha

[@rjlanhoward26]

Badass man, that swap does look pretty easy.

[@StreetInspired1]

It's honestly really easy. The part that took 80% of the time was searching for a tool I just had in my hand 2 seconds ago and getting the transmission in the car haha

[@MachuPichuu]

Great Video, Would of be helpful if you released this about 2 months ago before i finished mine! Easiest way to separate the transmission from the engine is use a 2x4 or 4x6 piece of wood and prop it against the pitch stop mount on the transmissions and hit it with a sledgehammer. Then only use a pry bar or ultra thick screwdriver to superate it. It is definitely easier to just remove the shifter cables from the box and leave them on the transmission. You also don't have to remove any bolts from the rear trailing arm. Just remove the Diff mount bolts and lower the Diff. it would be good to mention that you should put the reluctor wheel on the correct way and lined up (for the crank position sensor). I put mine on backwards and the car wouldn't start and i had to take everything apart again. I did everything completely by myself and it was a royal pain to line up the transmission and i had to do it 3 times! It helps to use a transmission lift and a jack to line up the angle. Then basically keep wiggling and pushing. I use the longer bolts to slowly bolt it back together with minimal force. If it got too tight i would loosen and then wiggle and adjust more. when it was less than 1/2in together you can pretty much just bolt it together. You mention that the DCCD stays in automatic mode with that wire harness but that's not exactly correct. It's going to be sitting in the mostly open settings with significantly less power to the front wheel. As the DCCD controller applies current to locks up the DCCD more. Without a controller there is no power going to the controller. IF you have a 2018+ tranmission then the lockup is even less without a DCCD controller. As the 2017 and older use mixed mechanical lockup and electronic and the 2018+ is almost all electronic. You really should definitely get a DCCD controller. I used the DCCDpro spider plus with taps into the ABS. You cannot use a STI replacement Gauge cluster on the 2015+ WRX that works with the DCCD. The best thing to do is use the OEM DCCD controls and then a separate LCD for for the lockup display. DCCDPro also has an option to use the OEM DCCD controllers without a LCD display for lockup and you can guess the lockup amount by the color and intensity of the RED glow on the controls .

[@Tony-tk4ht]

Its about the journey bro

[@occamsrazor1285]

10:46 The old diff is an R160 type (means the ring gear is 160mm), the new on is an R180. This is the reason different axle are needed. In truth, that's not precisely the reason. Theoretically it's perfectly possible to have an R180 LSD (since the diameter of the LSD is what determines the diameter of the ring gear) with 25 splines, but that's just not the way they're manufactures. As a result, the 180mm ring gear is implicitly the reason a 27 spline axle is required. And when you change the axle spline count from 25 to 27, you also need new hubs. I'm not sure about your year, but in the case of the GC8s, a 27 spline hub is available on the 2004 STI AND should press into the GC8 axle housing without issue, enabling a conversion of a 98-01 2.5RS coupe to a Type R(A) R180 drive train (I don't know for certain yet. It's one of the paths I'm looking to explore. The other option is to either replace the axle housing entirely or build a custom axel with an R180 diff/DOJ 27 spline and an R160 25 spline on the ball joint side to enable insertion into the 25 spline hub)

[@evan_n6136]

great vid when you're undoing those struts though I would put something underneath the arms so they don't drop like that. i've never had it happen on my wrx, but I did that once on my civic si and popped the cv out of it's inner joint. if that happens you have to do either A) rebuild the cv or B) (the easier option) buy a new axle. really can't knock you for it much though, this is a hell of a video you put together

I usually grab a hold of it and don't let it drop or keep a jack under it but I was really rushing this swap since I only had about an hour per day to work on it and new I was replacing all 4 axles anyways.

Great video on the STI swap, this will help me not make those same mistakes. Glad it all worked out. One question, the trans carrier you used was the wrx or sti carrier? How did you sort the exhaust mount situation for the wrx exhaust?

[@StreetInspired1]

I used the wrx carrier and as of now I don't have an exhaust mount. So far it seems fine but I'm sure it's extra stress on it do I'm hoping to come up with a solution soon!

[@MachuPichuu]

@@StreetInspired1 It works fine without the exhaust mount but its a PITA to line up and bolt up the mid pipe. i had to use a jack to get the midpipe in place. I believe that mount is mostly just to help get the exhaust in the correct position and line everything up. You can use the Stock Exhaust mount, hammer it flat and drill a new hole where it lines up. There is a similar bolt you can use on the left side STI Transmission for the mount.

I didn't adjust my clutch at all however with this setup the clutch pedal didn't have much give and was right st the floor. I'd you're having trouble you may need to adjust your clutch pedal. But before you do that you could check to make sure your slave cylinder is functioning properly by having someone push your clutch pedal down and make sure the slave cylinder is pushing the clutch fork. It could be a few things, a bad slave cylinder, a bad master cylinder, air in the clutch line, or the clutch pedal itself needs adjusted. I would start with the adjustment as that's the Free option and see if that fixes it!

TOTAL COST -$16,000 Add mods to sti to get it to the same power as my current wrx: $6,000-10,000 NEW TOTAL COST: -$22,000-26,000 Cost of entire 2020 sti drivetrain swap and new clutch: -$7,000 Total difference to trade in to buy same year sti with similar mileage instead of buying the swap: -$15,000-19,000. So I saved $15-19k by swapping arguably the most important part of the sti into my wrx.

@@StreetInspired1 Nah, that’s dumb.

[@StreetInspired1]

@@richardburns9772 it's dumb but it's true...

[@MachuPichuu]

@@StreetInspired1 Quite true, but a little exaggerated. Definitely not cheaper with a 2020 WRX. On an older like 2015 it's usually not much cheaper. I spent around 1k on my Brembo swap. I really like the Stock block FA20 and believe its a much superior engine.

How to STI swap your 15 WRX: sell your WRX then go buy an STI. Done and easy. But why though? The WRX has a better 0-60 and quarter mile.

[@StreetInspired1]

I wouldnt give that credit to the transmission 100% The wrx has a twin scroll turbo that spools instantly. That really helps the 0-60 times. But it's a very common swap. Wrx transmission can barely handle the factory horsepower, as soon as your start modding most people have issues with it, such as myself. And rather than spend $2-3k replacing it with another split case wrx transmission that will blow again in another 10-20,000 miles I went with the sti drivetrain swap for $6k. The sti transmission has been supporting 700-1,000hp cars for years. And I got a 2020 sti transmission so it's even stronger because in 2019 they switched to beefier carbon synchros. My hope is that this drivetrain will support any future engine build I go with.

[@Blue_Ghost-X]

@@StreetInspired1 fair enough. To each their own. If you plan on making higher than stock power I can see why you would want to do this but again it’s alot of work when you could just buy an unmolested STI. Overall great vid man and I hope you have a nice Christmas.

[@StreetInspired1]

@@Blue_Ghost-X Thanks man, you do the same!

[@Carnagex91]

Why not just buy an STI right off the bat? smh

[@StreetInspired1]

Because not everyone wants an sti. Because I bought my wrx with recaro seats and brembo brakes for $8k less than the base STI. Even with the sti swap and all the money I have into performance mods I now have the most important parts of the sti. The drivetrain, the brembos, and the recaros. At this point now yes, I could've bought a stock STI. But instead of having a modified 400whp car that gets 25mpg I would have a stock 260whp sti that gets 15mpg. No one plans on blowing up their transmission when they buy a car. So the more appealing option is the wrx. After the transmission explodes it makes the most sense to replace it with the sti transmission rather than replace it with another wrx transmission and then sell it for an STI. Good way to lose a boat load of money.

[@MultiLuispo]

Why would anyone go through this just buy a sti from get go or sell the wrx and upgrade imo

[@StreetInspired1]

Because buying a new wrx transmission for $2-4k to replace my broken one. And selling the wrx to get an sti would cost somewhere in the neighborhood of $15k-20k. The sti. And then it would cost another $10-15k to get the sti making the same power as my wrx. Just seems really stupid. I'd much rather keep the car and make it better. We live in a throwaway society where everyone says "this car isn't as fast, or this car broke" and they sell it to buy something else. I'd rather keep this car and make it better and better.

[@beefster1882]

Orrr orrr. Spend 6k more and get an STI! Save your money and stop wasting your time

[@StreetInspired1]

I sort of partial to the FA Platform more than EJ. As far as I'm concerned I just made my dream setup.

[@lucian7182]

If you can find 2021 still they are not 6k more than a Wrx base. My 2020 Wrx base was 27k my 2021 sti limited was 44k with a few options.

[@StreetInspired1]

@@lucian7182 exactly. It's roughly $15-17k more for an sti not to mention everything that's done to this car would just be useless and a waste of money and then I would spend $10k on an sti to get it to where my wrx is right now lol

[@MachuPichuu]

@@StreetInspired1This is how i felt. love the FA20 platform but just wanted everything else upgraded. Great Gas mileage too. I Just built the car how i wanted it. The only issue currently is the steering.... Maybe i can use the the new 2022 WRX electronic steering in my 2015 WRX.

[@300zxdriver]

Just buy a STI.

[@StreetInspired1]

Sure, let me just replace my broken transmission for $2k and then sell my wrx and buy an sti and lose $15-20k instead of getting the sti transmission for $6k 😂

[@mikeboost1]

Sti swap? Sti transmission swap. Not engine.

[@StreetInspired1]

Correct. Most people who own a wrx call it an "sti swap"

[@kakkeemusic]

Your not going a STI swap!! Your just doing a STI Trans swap!? Click bait.

[@StreetInspired1]

How is this clickbait? Because I didn't say "STI Drivetrain swap"? Literally everyone calls it an "sti swap" that's the only "sti swap" you can do on this car. No one is going to swap out their FA20 for a 20 yr old EJ25 lol

[@jank1464]

:How to STI swap your 15-21 WRX... :Trade it in for a 15-21 STI. Problem solved.

[@StreetInspired1]

Might be the right move for some people but I don't have $15-20k to switch cars for a broken transmission.
