Budget rotary, in this economy? Building a 13B Rotary i8: EP 2

[@cskinner89]

Having previously forked out the cash to build a lightened, balanced, ported, studded keg, I can very much appreciate how good it is to be lucky lol

[@CaleTeale]

This series will be awesome inspiration for my own build. Mines not quite as intense but still fitting an engine that was never supposed to fit where it’s going. The CAD and custom parts are on another level to me tho. So nice to watch someone who knows what they’re doing. It seems like you worked out how to do everything before making your video series - which I’m sure everyone appreciates.

[@CouchBuilt]

Bold of you to assume I know what I’m doing.

[@CaleTeale]

@@CouchBuiltsorry - you know how to pretend like you know what you’re doing* 😂

[@Nafeels]

If you somehow want to significantly port your 13B someday I highly suggest you’d go for semi-peripheral porting rather than bridge porting. The “bridge” in a bridge port isn’t meant for long term use considering the rotor edge only has that narrow piece of metal to travel along. Other than that, you have a studded block and lightened rotors. Wow. Can’t wait to see the rest of the project manifesting.

[@paulomedina1976]

I am obsessed cannot wait to see the next part

[@golfy808]

That's so awesome!! What a find... great to hear someone that is clear, precise and knowledgeable 👌

[@nobodyspecial5026]

probably REC in Canada did the studs with their CNC service. They also provide CNC intake porting as well. Given how nice the porting is it may have been their work.

[@CouchBuilt]

That’s interesting. The motor came from a JDM swap retailer in Canada. I’ll have to look into that further. Thanks.

[@gafrers]

Great score for sure. Most times you hear "horror stories" from 2nd hand wankels. Looking forward to more videos on this wonderful project

[@CouchBuilt]

I watched a lot of wankel horror stories at the drag strip in the early 2000s. I actually never gave them much consideration until I got sucked into Rob Dahms videos.

[@phenomanII]

Definitely understood that intro once you tore into it.

[@K03sport]

" he shoots and scores..." [in honor of March Madness]...can't wait for the real spicy stuff to begin 🌶️🌶️🌶️🏁

[@hathaway.1166]

This is actual engineering stuff, i love it

[@bloody_pinata]

That's a hell of a find dude. Sick motor

[@RedBatRacing]

Those studs are going to be essential with your front engine mount. I was going to post on your last vid that there is a reason the REW has rear engine mounts. They reduce the torsional stress on the engine. These studs will go some way to compensate for the backwards mounting.

[@madrew2003]

Not silly, lol. This project definitely has my interest!

[@Jamesashleycoyle]

🎉what a find! Pumped you’ll have a solid rotary

[@AngelLopez-uf7og]

I subscribed halfway through the first i8 video, can’t wait to see how it turns out. You need more eyes on this build for sure

[@GetUpFalcon]

Thanks for the explanation on surface prep and finishing. I bought an old vice yesterday which needs a restoration. Comment for the algo, lets get this channel up in lights!

[@censoredialogue]

ngl seeing everything from a rotary laid out on a small table has me thinking an FC RX-7 may be in the cards for me as a project car one day. they seem incredibly simple compared to a piston engine, and as a Subie owner i already have an affinity for high maintenance motors 😹😹

[@CouchBuilt]

After getting all apart, there was definitely a “wait, that’s it?” moment

[@censoredialogue]

@@CouchBuilt lol for real!! loving the past 2 videos. super excited to see how the build progresses!

[@sLim88CPC]

Fantastic job, I love holistic approach, meticulous, very satisfying to follow. Keep them videos from progress coming good sir!

[@youremostwelcome]

This project is unspeakably cool.

[@mclarksays]

my favorite video series, seeing behind the curtain on your socials leading up to them.

[@beforebefore]

Oh wow dude... I don't know how you're able to restrain yourself with that absolute win!! I just got a whole lot more excited to see how this project turns out! As an i3 owner, this would be a cool sleeper mod... if not for the very recognizable exhaust signature of the 13B.... 😮

[@AnthonyGriz]

Awesome to hear you talked with fellow aussie Jon Blanch, he's built and sorted a few of the worlds fastest 6-second rotary motors. Definitely both good and lucky with that motor 100%!

[@iankirwan8156]

Fantastically lucky with that engine, well done

[@KurtAndresKA]

Sick 13b, and for that price wow!

[@toxinism]

S4T rotors nice. Front CW is slugged as well should be a good motor. Xtreme make the best stuff.

[@Syscrush]

Can't wait to see the manifold design and fabrication.

[@user-oz5yk9bm5c]

the algorithm really needs to pick up this video. commenting for the algo!

[@mike032390]

The Facebook marketplace and eBay searching “ searching only to find used up parts for top dollar” 😅😂 I felt that shit😂 that shit was 😂wayyy too accurate and the comment I’m just a dude in a garage trying to make some cool shit 😂I like this guy

[@hobbawobba]

Bloody good score there aye bro. Definitely a few nice bits included 🤙🏼

[@CouchBuilt]

Yea it was a great score. No small part of why I was able to choose inconel over stainless for the turbo manifold.

[@kz6fittycent]

0:22 - Hey! I know that reference - Outlaw Josie Wales - Lone Watie said after they thought about it a long time, they declared war on the Union.

[@martynclinton8092]

Your cad/ fusion workmis amazing Im guessing that this is your line of work… not just a hobbyist! Let me know if you would be interested in some work.. Looking at building a rotary motorcylce feom scratch but need help with the epitrocioid!

[@BLoudermilk]

Epic

[@Johnnytomatoseed]

5:09 seems to show a crack stemming from what might by passage for something

[@CouchBuilt]

Its not a crack. It's the partial outline of the passage from the rotor housing. The shapes of each casting dont perfectly align. It's just more pronounced on that side compared to the other.

[@GoPotato69]

do you have any engineering background of anything or just self taught? cant wait for more updates on this build

[@CouchBuilt]

Business by formal schooling but self educated on the technical side. Just always took a deep dive on any topic related to a problem I had to solve. 20 years of that accumulates.

[@GoPotato69]

@@CouchBuilt great to hear, I'm comp sci by schooling but passionate about everything mechanical/hardware/eletronics/cars Autodesk, 3d printing, and the like all from just being curious/a few classes back in hs rest is KZbin degree ig lol, wish u luck on your problem solving adventure

[@3toedSloth75]

Super lucky. That's easily $5000 of work and parts (assuming you close the engine yourself).

[@AdamBath]

Not sure those are REW rotors, should have machined surfaces in the pockets on each face if I remember right from the REW rotors I ran in a Turbo II build years back.

[@AdamBath]

Yeah, just confirmed that with a quick Google search. Guess it would make sense if they were doing a low compression high boost build.

[@CouchBuilt]

Interesting. I’ll have to look into it. I wouldn’t mind a little higher compression as it’s not the early 90s anymore and tuning is a bit more precise. Lower compression and more boost would be just as good.

[@CouchBuilt]

After researching, these appear to be 87-88 turbo rotors, so 8.5:1 vs 9:1 of the REW parts.

[@jmirsp4z]

looks like they could be done by REC

[@CouchBuilt]

That seems pretty likely as the motor was shipped from Canada. Someone else dropped REC's name a few months ago and I reached to see if I could get any history on the motor. Unfortunately, I didn't have enough info for them to connect the dots as it's a pretty standard higher HP spec setup.

[@simmonsdavon]

I’m just a dude in the garage trying to make some cool shit❤

[@E36Variance]

Small recommendation to take your editing to the next level: try to remove the instances of lip-smacking, tongue clicks, and other mouth noises from your voice tracks as much as possible. Since they have a tendency to immediately follow a period of silence right as you start speaking again, they're a very sharp, distracting noise that many viewers will find off-putting. That fact that your audio quality is generally very good makes it even worse. I believe that most modern video editing suites have filter either built-in or available as a third-party addon that can automatically remove these, but you can also manually remove (or at least, muffle) them by zooming into your audio track and searching for instances of peaks immediately following a period of silence.

[@CouchBuilt]

100% agree. Figuring out this editing stuff as I go. Most of my audio efforts have been clipping out excessive uhhh ummm moments. 😅

[@ChrisCanDoIt]

@@CouchBuiltyour audio is fine. Keep up the good work. Keep your focus on building and don’t lose too much sleep on that little sound detail. Not annoying at all, didn’t even catch it.
