I've got a bugeye wrx with a v7 ej207 that needs a refresh that I am going to turn into a race car. Really considering pulling the ej207 and k swapping it after seeing this. Still would need to build the transmission though.
@@BlackthumbTV yeah. I feel that. Filming can take a one week project and turn it into two weeks. Love the concept though! I would like to do the same thing with a B series. Can't quite afford the K. But I can't find an adapter plate and flywheel for the B.
@@BlackthumbTV you are absolutely right, the D and B series both do rotate counter clockwise. That detail had slipped my train of thought on the subject. I would say your guess is right on the bullseye.
How did you learn all the skills it took you to make the car? Welding, casting, 3d printing, wiring, coding? You are like a jack of all trades. Some of those things can be really hard to learn and can take a lot of resources like money and space. I'm in college for business but want to be doing stuff like this. Should I focus on a major like engineering? I've had a saabaru w an ej25 pushing close to 350hp. I sold it for college even though I couldn't really ask for a better car. Currently, I have a NA GC8 wagon and the 5spd trans just killed itself. I want to EJ swap the whole thing for simplicity.
I'll start off by saying that I didn't go to college. I don't have formal education in any of this. My actual job has nothing to do with cars, in fact. This is just a hobby. The main thing I can say is that you need a goal. I tend to hyper-focus on the goal and learn everything I need to achieve my goals. I myself started with Subarus, and my first project car was an automatic GC8. I started by manual swapping it. This taught me the basics. I ended by turbo swapping it. Something that actually taught me a lot was trying to be cheap. I learned that if I bought an expensive standalone ECU I could cheap out on many other things and get away with it. I couldn't afford an actual WRX engine, so I built a turbo engine with a junkyard EJ22 and Craigslist EJ205 heads. I opted to wire the standalone in by hand which ended up teaching me more than anything I've done to date. When I did all this, I bummed shop space off of friends. As the phrase goes, "Jack of all trades, master of none." I'm sure many people watching this could point out many issues with this and my other builds. But at the end of the day, it runs. It drives. It's fun. That's what really matters.
Does the factory K oil pan work? Reasons to go with a K series vs a J series? Someone J swapped an sti recently, and I love the j35 in my accord. But a J will never have the subie rumble like a k could
Factory K went oil pan was fine. Wired in an oil pressure sensor and the ECU never tripped low pressure safety. I haven't played with a J yet, but I think they're pretty neat and would like to mess with one at some point.
I’m curious about the throw out bearing situation. I saw the clutch looks like a normal push in style operation vs the usual EJ pull style throw out bearing with the lock ring. Did you adapt the fork and slave to accommodate a push in style? Or just adapt the clutch to a pull TOB? Or am I overthinking something simple cause I’m a smooth brain? Love the content keep it up!
Subaru EJ transmissions come in two styles: push and pull. This is a naturally aspirated 2.5 RS trans, and is a push-type. Judging by your comment, you probably own a turbo model like a WRX or STI, which are in many cases pull-type. The adapter kit comes with a flywheel that works with regular Subaru clutches, just pick which type when ordering.
yup nailed it. I have a wrx and didn't even stop to think the NA bois were different. classic smooth brain moment on my part. thanks for the reply! can't wait for the next vid! @@BlackthumbTV
Hey.. I have an impreza gc3 1.6 fwd with sport suspension rollbars, strutbars, poly bushings etc. I always had the idea of changing motor but leaving it fwd as a rare impreza with performance. I bought it with 60k miles and put 30k miles on it.. so the small engine has plenty of life that I intent to enjoy. but this swap is cool! I wonder if there would be any issues given the power would go only to front. I dont know if gc3 gearbox could take it either.
I'm sure it would be fine. There's even a chance the original honda transaxle would fit, but I'm not that familiar with their setup. Good luck with your project!
Question since you mention on the other video "the boostedbois" build You did drop the subframe(thiers i think is maybe 2" 1/2 inches i could be wrong) Or i missed the part where you mentioned?? Also Skunk 2 sells a low profile valve cover just in case you want to find a solution to the motor being exposed
I did indeed drop the subframe, around three to four inches I believe. The lower profile valve cover wouldn't make a difference. The actual timing gear is well above the hood line, so no matter what it's going to be sticking up. It's simply a tall engine, so it's part of the experience.
Extremely efficient; I believe this one was much too big for the power level I was running. Intake air temps rarely moved much more than ambient which was fun to watch in the datalogs.
Sooooo I know you don't answer questions buuuuuuut: What is the best fuel mileage you're getting if you drive like grandma? Also did you happen to route your coolant hoses into the old heat exchanger system to allow you to have heat? Also please post a bunch of High def pics of your engine bay on your website, the masses are dying to see more :))
You should probably watch the most recent video on this car 😅. I think I got 15-20 mpg, but that was on E85. Never drove it like a grandma though. I did indeed have heat working, line routing was easy.
Great question! Just pulled some datalogs and it seems to be around 20mpg to 25mpg, on E85. Which means if I were running normal 93 it'd be probably be around 25mpg to 30mpg ish, maybe? Either way, I feel like I don't fill the thing up often at all, especially when compared to my 2005 WRX.
Since I cant currently reply in the Roasmycar thread I'll reply here. How original K swapping a Subaru, whats next LS swapping an RX8, oh wait. Gonna LS swap a Mustang next? At least step a little outside the box, like that dude who Rotary swapped a C7.
Can't wait for you to blow up. Your content is so entertaining and your comedy is on point! You'll get there.
Your personality and humor is amazing. Please keep making content!
Look forward to a video about a legacy I'm H6 swapping!
Bro, I don’t know how you don’t have more subs. Your videos are gold.
Dude keep making these. Your Channel is gonna blow up with your sense of humor and comedy. Also where can I buy a “this blows” shirt
Thank you for your kind words! I make the shirts myself. Shoot me an email and I'll hook ya up: bt@blackthumb.tv
Subaru leagues way more oil than Honda specially, head gasket
Idiots don't maintain their handas and Subarus so the concensus is based on that generality
I’m with you. Built a 2wd ford ranger ls turbo 5spd autocross style truck 100% me. Custom everything. What a journey
Love your Suttle humor 😅 glad to see this car holding up pretty well, can't wait to see what more you're gonna do on it
It needs a nice Hood scoop to complet the look.
Just recently discovered you and love how concise and humorous you are, u got a new subscriber
I've waited to long to subscribe lol I'm in man. Love all the DIY and knowledge brought together inside of classic comedy. Your gold
awesome video. Glad I found you.
Lol now I get why you left the clearance hole open!
Mine only gets attention when the hood is popped

Would have loved to see a build video on this thing. I wanna do this to my outback. I'm done with the EJ25
Maybe at some point. The problem is that when i start one of these projects, I basically speed-run it. No time for video cameras and such lol
@@BlackthumbTV yeah. I feel that. Filming can take a one week project and turn it into two weeks. Love the concept though! I would like to do the same thing with a B series. Can't quite afford the K. But I can't find an adapter plate and flywheel for the B.
That's likely because the B series rotate counter clockwise, and the K and EJ rotate clockwise, if I had to guess.
@@BlackthumbTV you are absolutely right, the D and B series both do rotate counter clockwise. That detail had slipped my train of thought on the subject. I would say your guess is right on the bullseye.

Let’s go waiting for this video 😀
I would have put a comical sized hood scoop on it lol
Does the factory K oil pan work? Reasons to go with a K series vs a J series?
Someone J swapped an sti recently, and I love the j35 in my accord. But a J will never have the subie rumble like a k could
Factory K went oil pan was fine. Wired in an oil pressure sensor and the ECU never tripped low pressure safety.
I haven't played with a J yet, but I think they're pretty neat and would like to mess with one at some point.
@@BlackthumbTV good to know they don't have oil issues mounted the other way. Thanks for the quick response 👍
@BlackthumbTV Ohhhh You neerd.... and I'm neerd too becuse I noticed this. 0:00 Portal song reference
I'm making a note here: Huge success!
God this man is so attractive
i wonder if i could fit a k24 under the hood of my lifted outback. drivetrain and subframes already dropped two inches
That would be slick!
@@foxisretrofitting4556 yea if this ej25 ever actually throws the noisy rod I will.
@@malibusswagon If you ever do you've gotta make a video on that.
What adapter plate and flywheel kit did you do and or do you have a build list, please?

@@BlackthumbTV Fair enough ✌️
For your SubaruGears adapter plate did you go with the stock 15 degrees rotation or the 0 degrees rotation and why?
No particular reason, other than symmetry. Something like a 14deg would probably be fine as well.
I like boost boost too
How efficient is the ebay water to air intercooler and how much power could it support
Extremely efficient; I believe this one was much too big for the power level I was running. Intake air temps rarely moved much more than ambient which was fun to watch in the datalogs.

You should weigh it too
7:45 7:50 7:52
I nneeeeedddd it!
it's not "built not bought" unless you cast your own parts lmao
Did you measure the gas mileage?
Great question! Just pulled some datalogs and it seems to be around 20mpg to 25mpg, on E85. Which means if I were running normal 93 it'd be probably be around 25mpg to 30mpg ish, maybe? Either way, I feel like I don't fill the thing up often at all, especially when compared to my 2005 WRX.
@BlackthumbTV is that US mpg or Imperial mpg? Thinking of a swap for my Forester to improve reliability and running costs as a daily!
Not sure of the difference here, but that's a standard measurement we'd use in the US
@BlackthumbTV US gallon is 3785ml while Imperial gallon is 4546ml. Just depends which you're used to really but that's super impressive!
Since I cant currently reply in the Roasmycar thread I'll reply here.
