- Hello. Just wanted to make a video sharing a project I had worked on for my 1999 Miata. Hope you enjoy!
The setup has changed since this video has been released. New video:
• Honda CBR1000 ITBs on ...
The CZcams algorithm blessed me. Keep on making videos!
Well done, Ethan! You've amassed quite a bit of knowledge during your engineering modifications! Nice wheels too. Very tidy build. All the best, Rob (2009 NC 2.0 Sport)
I missed your comment!! Sorry Rob! Thank you as well, I bet your NC is very nice to drive
@@analoglyfe I think of my NC as a baby Gran Turismo. Can be comfortable over longer distances (we’ve been to France and Italy in her) but can be nice and quick on the country roads when one wants.
@@RobWhittlestone sounds like the best of both worlds
Just wow, great video! Will consider this heavily before turboing mine. Always good to see a fellow FSAE member with a miata😁
Thanks man! Fsae has been a blast these last couple years for me. Which school were you?
Very nice job! Good to see the attention to details, like the vacuum distribution block and the super clean throttle install. Well done.
Thank you! I have another video that makes everything look a tad cleaner too 😅
Better video than my first one, and you answered a couple questions i was thinking about.
You've really put some thought into this conversion dude.
A REALLY informative watch.
Good stuff, thank you. 👍
Yessir! I'm all about designing it well or not at all. Funny enough I have another one of these videos about some improvements
Beautiful NB , congratulations on the first video we support , we are watching from Las Vegas
Thank you so much!
We support the build fam we are car enthusiasts and automotive youtubers
id prefer to go turbo, but props man really creative way of fitting ITBs on a budget. mad respect
Heck yeah!! Stoked to follow development
Thanks!
very interesting video! i my self want itbs to so this was cool to see. Great vid
These are going to be game changers
Congrats dude! Better video than most of the small car channels.
Thanks man!
Oh god yes i love this its so creative im so glad i was recomended this.
Nice I am super interested in this! Please keep me posted if/when you come out with a kit I would definitely invest!
Update coming soon!
Yes! Kit please!
Do you have a kit?
Awesome job! the video only needed a little sound check of how those beauties roar but I already checked your other uploaded videos
Thank you! I definitely should've started them up!
I don't even have a Miata but hey here i am watching this and really enjoyed it! :D
I appreciate it lol!
my man fkin slapped on a motorcycle part on a car. Guys try to process that. This part is not even considered to be a "car" part. Its a FKIN MOTORCYCLE PART XDDXDX. Bro is a legend
Lol thanks man!
Very cool mate, looks very well done! I'm looking into the ITB route. If you're planning production of the manifold etc, I would be highly interrested. Greetings from The Netherlands
Thanks! I should be getting close to getting a first real product made, stay tuned
How’s the production of these coming along?
Thanks for this video, it has explained quite a few things I couldn’t find info on elsewhere.. Before I dive into it myself I wanted to know more on the rest of the set up other than the actual throttle bodies and this has given me a better insight! I have a straight 6 so my biggest challenge is finding a set of throttle bodies to make work.. I’ve thought about the idea of getting 2 sets of inline 4 bodies and modifying 1 off each end to make it into 6 but didn’t want to go buying them and then mess it up 🤣
Sounds like a fun project! Best of luck and glad I could help
Your idea of modifying two sets of inline 4 ITB's reminded meo of these guy's setup where he wentthe other way and combined 4 throttle to make a set inline 4's. Might be useful to you:
czcams.com/video/1dDZ4bqmeuY/video.html
This is obv old and my advice may be late, but instead of modding BOTH ITBs, just cut ONE in half so you have a 'stock' one and two 'half' ones. I'd recommend 3D printing a manifold adapter out of carbon fiber infused ABS
Edit: Wow I sent this reply ~30 seconds before he went and talked about his own carbon fiber 3d printed adapter! Well done Ethan!
Great overview mate. I follow you on the gram and am inspired by what your doing. It occurs to me that if you could divide the runner/adapter into two parts you would have a lot more options for printing it as it would probably fit in the bed of a standard prusa size printer. You could get some aluminium or steel plates laser cut that could hold the ends together ( maybe with a thermal break plate too ) to maintain rigidity tho it might not be needed.
Ethan Vermillion nice one! I'm curious, where are the injectors on this setup? Are they on top of the printed runners? I'm a industrial designer so I do a lot of solid works/ printing etc for work too; so happy to help in any way. I have a couple of other ideas as well that could potentially help make the runners if you wanted to discuss let me know? I'm based in the U.K. so my miata is rhd, not sure that your current positioning of the manifold will clear the brake master cylinder.
@@nehok that's cool. I'm not sure about the booster clearance like you said. For the 1.8L, the fuel injectors have a spot on the head they bolt and sit on to, so I actually just leave it alone as configured stock
Ethan Vermillion oh right that's nice, I didn't realise they go straight into the head. That makes life easier. Yeah I'm sure you could do a slightly different runner that brings the itbs a little further forward if needed to clear the bmc.
@@nehok yeah I definitely want to make them more compatible with other gen Miatas and rhd too
Ethan Vermillion great stuff. I'd be happy to do some mocking up on my car if that's helpful. And like I said I do a lot of printing and make functional pieces for R&D etc so could discuss some printing ideas if you want too.
Good stuff! serious business for a first youtube video
Thanks!
Very informative ice job 😊
Thank you!
That’s amazing, love it, what a chance !
Yo ethan you just showed up on my algorithm 💀💀
👀😳
Well spoken, informative! Thanks
Awesome brother !!! keep up the great work!!!
really nice job
Very impressive dude!
Thank you!
I’m attempting to make an adapter with my Brothers help for Yamaha R1 throttles with DBW for my NA8
With Haltech I can get idle control without an IACV just the DBW among other great features
Sounds fun! Best of luck. Any reason you're sticking with dbw throttle?
@@analoglyfe
So I currently have 4AG ITBs and I’m not particularly impressed with idle control. DBW greatly improves and simplifies idle control no longer requiring a IACV.
Once I learned Haltech can do other neat things like easy to implement traction control, cruise control and anti stall with DBW I was fully convinced it is better and simpler. Valet modes can be set where the throttle % is limited and tuning is made easier by being able to set to throttle position exactly.
Also DBW is safer, stuck throttle can be detected and engine shut off whereas that is near impossible to detect in a traditional throttle body.
Howdy howdy howdy.
That’s dope !!!!! I should ITB my single cam ! But I’m trying to beams swap!
Beams swap would be cool!
Great video buddy 👌🏻👌🏻
I want to print this intake for itb's and then put boxed system on the velocity stacks to boost it.
Good work!!!
Thanks!
Plz make a kit! This is so cool and ive been wanting ITBs but been having issues on price and all.
You got it!
My 2014 is a NC with only mod is the GWR catted header and the Fab 9 Versatune mod. Thanks
Sorry my mistake. I couldn't remember if 2014 was the switchover year or not. Nonetheless I'm not sure if I would consider one
@@analoglyfe Thanks
Nice man subd for updates. Love to hear about another option. I'm going to try gsxr1000 boots soon on my VVT spare.
That sounds sweet! Hopefully I'll have an update within the month
@@analoglyfe nice! If you get something out by then for cheapish I may go that route first. I sorta want to see if I can't just tap a flange for the boot's holes and port match while reusing the bike injectors. Wouldn't be a ton of room for stacks etc and I would probably need to add some additional support to the itbs but would be the cheapest/simplest route. Hadn't thought to measure the area of the ports either so glad you mentioned that as I think the boots I'm looking at might neck down some too. Also I want to boost it with the ITBs so your channel is perfect. I'm planning to run water air intercooling as well, might keep my AC just for that lol
@@accordv6er awesome, I've see a lot of people do the gsxr throttles yeah. I thought about it too, but I just preferred some other pieces the Yamaha set had. Nonetheless, it'll be cool either way. The one nice thing about the gsxr throttles is I've seen people space them out to the Miata port spacing, whereas the Yamaha ones can't. I'm targeting no more than $300 for the manifold and I'll have some add ons too like a throttle bracket and what not. You can pretty much piece the entire rest of the kit together for another $200-300 including the throttles
@@analoglyfe that's a noble goal and I think a lot of people will go that route given the how ubiquitous turbo cars are now. Yeah I picked them for the large runner and spacing is very close. Enough that I may do blending on the head even if they can bolt straight to a flange and the injectors work out.
I'd be interested in a kit if you sell them. Also can you do methanol injection on the r1 injection ports?
Great work! I am inspired. Where did you put the IAT?
The iat was just moved to where the filter sat, it wasn't anything crazy 👍
If you ever develop a kit for it, I'll be interested in buying one.
Good to hear! It's taking longer than I planned, but I plan to come out with one soon
Can you make any more of those manifold spacers? You could deff make some money
I am currently in the process of doing so, it's taking a while but I will have them soon
Blud said front wheel drive 😂
Those moments where you just say the complete wrong thing haha
Hi there , great project. Do you think these itb would be suitable for a 1.8vvt?
Many thanks
Absolutely. I'd expect very similar power numbers compared to my bp5a. I have an updated kit coming soon with some new changes too
Hey set up look great, you ,making any manifolds
I will be for the newer CBR setup I made. I have a video on it
hey man i was wondering what center console delete that is? looks awesome!
It's the Carbon Miata short console
Aye konig Dial Ins!!!
I'm interested in a manifold to fit Toyota silvertop ITBs to a BP4W. I'd like the resulting installation to be angled up and to have an integrated vacuum block. Can you help me?
I can't help with that, but a company in the UK called DanST engineering can. He can likely make what you need if he doesn't already make it
Great info. What year of Yamaha R1 did you used?
I used 2007-2008 throttles
FSAE miata gang 👊
What school are you? I go to Cal Poly Pomona
Nice man!, what year model r1 is this?
They are 2007-2008 throttles
A follow-up question, is there a reason for the connecting manifold to be so long?
Or you made it longer to help with the angle on the outside runners?
There is a point to some extent. The outside angle as you mentioned is one. Another reason is to angle the itbs up but not too much with enough space to clear the fuel rail above, clear the shock tower for when the itbs are added, and to match the port entrance angle on the head as close as I can so air enters as smooth as it can
@@analoglyfe makes sense. was just comparing it to other Miata specific (and super expensive) solutions and I noticed your stick out much further.
Definitely looking forward to the kit, do you know if it will work for the 1.6 as well?
@@slashles1 The 1.6 is a bit tougher to implicate, but I am looking into it nonetheless. The part that makes it a little harder is the fuel injector seats. On the 1.8s they sit on the head, so I don't have to worry about them. But as you know on the 1.6, the manifold provides the seat location. So in order to make an adapter for the 1.6 I will need to add those seats. The planned idea is to use the stock location so one can keep everything stock and bolt them on. I'm going to come out with the 1.8 kit first, but in time I will see how a 1.6 manifold could be made
What are you doing for your injectors? Are you using the OE injector location?
Yep oe location and stock injector setup
@@analoglyfe what is the distance from the throttle plate to the injector?
@@GerryElegadoJr Not sure exactly, but since I run the stock setup, it's about 5 inches or so after the throttles
50$ at a junkyard will get you a honda cbr 1000 itb setup. Did my entire setup for under 150$ using actual steel pipes lol.
Awesome! Would be cool to see how another person set up theirs. How did you deal with velocity stacks and filtration?
Question, as far as i now raw fdm 3d prints are not airtight, was something done in postprocessing to the manifold, velocity stack ecc..?
That's correct for most materials. For carbon fiber nylon however, it's higher printing temp relieves the user of that issue. There is also a sintering process that can additionally be done for it to be extra airtight. Thickness also helps. For the non carbon fiber nylon parts in the setup, they're not experiencing vacuum and therefore don't need to be vacuum tight
@@analoglyfe got It thanks, adapting intake system from a bike to a car is beyond cool, well done!
Very cool video. I have the LRB doors too, but took them off for now. I couldn't figure out how to make them stop squeaking as I went down the road. They were rubbing on something on the backside. Might try them again with some felt on the back side or something. I really miss the arm room I had with the flat doors.
Thank you! And yeah I loved them, luckily didn't have a squeaking issue
Getting to the point; how much for the 3D printed parts you made and actually and list for everything you got to make a working system.
Better yet is your kit ready to ship??
I won't give an exact number on the 3D printed cost just because I plan on selling a kit soon, but in total the setup you see in the video was just under $450. That includes every part needed (besides an ecu). When I come out with a new kit that will have an aluminum manifold among other things, I will make sure to post a detailed video on everything you would need. That should be coming within the new year. The actual kit will include every adapting piece needed, and the normal parts like vacuum lines and velocity stacks will be in the hands of the buyer to decide for. I'm targeting to sell the kit for around $400
Hey I have a question I'm trying to run itb on my svt focus. Would you be willing to make a intake runner for my car ? Also if you go. On ebay they have really good itb velocity stack different lengths for better power low high there tunable
Unfortunately I wouldn't be able to make a setup for your car, as my resources only extend to Miatas, but perhaps you could have DanST Engineering do it. He has a shop in the UK that makes all kinds of ITB kits for various cars. Thank you for the velocity stack info, I haven't seen them on eBay yet. Would you happen to have a link? I might be interested.
Are you running the Megasquirt in speed-density or alpha-n mode? I'm curious if that vacuum manifold is enough to run it using primarily the MAP sensor.
I used to run just speed density, but ended up switching to itb mode, which uses both alpha n and speed density. Speed density is used for anything under 87kpa, and alpha n is used for anything above 87kpa. I'm not sure what you mean by enough to run it though
@@analoglyfe cool thanks for the info. I'm working on my own Miata project using a 3d printed manifold and CBR1000RR throttle bodies, and stumbled onto your video. The design of the manifold you choose could in theory condition the signal to work better in speed-density mode so I was just curious how that manifold worked out for you.
Super cool project and thanks a lot for sharing your experiences with it.
@@MachiavelliPWNS no problem, good luck to you! If you're curious I also recently swapped to the cbr 1000 throttles and made the same kinda video on my channel
@@analoglyfe thanks! I just saw your video on it and SoW (I'm from SoCal), funny coincidences.
@@MachiavelliPWNS haha yeah cool!
Have you brought these into production yet, from reading older comments? Would you be making this setup for NA and NB or NB only?
I decided against it as I did not have the time to allot for such a thing, but I did make a video this year releasing all my files in a later design. That would allow anyone to have a go at making it themselves 👍
@@analoglyfe Sweet! Will look into it. Would probably be much cheaper than going the Jenvey or some other produced route. Did you even get on a dyno?
@@jonathanrice-exec11 yep I have all the information in the videos. On the last setup the car made 148whp on a stick engine with an exhaust and the ITBs
@@analoglyfe Jesus, that's good! Thanks!
I’ve been wondering about doing ITBs on a Subaru Flat 6 like the EZ30. How would you go about making the ITBs work by drive by wire instead of through cable? The car the ez30 is in uses an electronic throttle so I wouldn’t be able to use a cable.
It would likely require a lot of in depth calibration. You might be able to wire it up successfully to the oe harness, but then you'd have to find a way to calibrate it and make sure it's being controlled well. I don't know too much off the top of my head though
@@analoglyfe I researched a little bit an saw 2 different use cases where they used triumph triple speed motorcycle throttlebodies, so I wonder if those would work. I don't know if they're wire or cable though. Looks like there's hope! Oh, and one of the guys I saw using them on the ez30 ended up CNCing the connecting piece between the motor and throttle bodies. He did have full time access to a CNC machine though.
@@inaNis_ that sounds promising! Since that bike is pretty new I'd be willing to bet it's drive by wire
Does it take longer to print with the CFN? I've never tried it
Nothing I've noticed about an increased print time. Just requires printer upgrades
I have a 2014 miata GT. Is it possible to have an ITB for it for less cost. Thanks
It might be possible. I'm not sure if/when I would look into NDs as they might have some extra hurdles compared to the simpler NAs and NBs. Since my personal vehicle is an NB it's easy to make one for it
Would you be willing to share that STL at all...?
As of right now I won't, possibly in the future
How is the 3d printed manifold holding up ? What exact brand did u use
It's holding up great. I've used the SainSmart and eSun filaments. Both were great
@@analoglyfe did you print them yourself ? What was the infill density etc ?
@@choco107 I had a friend print them. It's 100% infill (solid). I can't remember the exact settings that were used beyond that
Interested!
Join modified miata na or nb group on Facebook. We'd love to have you in the group. Is there a file for the intake to be 3d printed?
Thank you! I don't currently have the Miata anymore, but I used to be on those pages. I do in fact have a manifold file and all supporting parts for print, it's in my latest itb video, there was a major design change since these R1 throttles
When are you selling the kit?
I'll be releasing another video soon with the details, sorry for the wait!
quick question, did you bake/dry your cf nylon before printing?
I did not, just took it straight out of the packaging and printed. I believe it's more of a concern if it sits out of the packaging for an amount of time
@@analoglyfe thanks for the quick response! I guess I’ll start printing my manifold now then. One thing I’m worried about is that the bike ITB’s i got are 16% smaller than my ports. Do you think that would hurt my performance much? Would they be worth running now? Or should i just start looking for new ones?
@@nes3382 what engine do you have and what size are the throttle bores for your itbs?
@@analoglyfe i have an m44 (twin cam 1.9l) which makes 138hp from an e36 318is and the itb's are 41mm but they taper down to 35mm for some reason which i did not consider.
@@nes3382 you will likely need at least that 41mm all the way through. From my testing and observation, 35mm would be too small
Rip smog 😂
The necessary evil 😮💨
i see no evil!@@analoglyfe
Would you make an adapter for gsxr tb and a plenum? Would love a set of itb on my turbo miata
I might consider it, but it wouldn't be super soon. I considered the gsxr throttles a while back but I leaned toward the Yamaha stuff because their slightly different design made it easier and more seamless to adapt to the car. What would be a more realistic thing for me would be making a plenum for the R1 throttles, so you could essentially do the same thing you described
@@analoglyfe would be awesome to see. The large r1 bodies seem like a good upgrade for a boosted miata.
@@X7rocks manifold should be coming soon 👍
@@X7rocks I've got a 1.6 Miata manifold -> GSXR ITB adapter that I'll be releasing soon, along with videos discussing it on my channel. 1.8 versions coming eventually too.
Hey, can yo ushare the STR file for the manifold or are you hoping to monetize? I have access to a high quality 3d printer.
I might have done it earlier, but I might actually be nearing a small production run using aluminium. While I won't give you the full model, I can give you the Miata and R1 flanges as whatever file type you'd like to make your own manifold with if you're interested.
And of course if you're interested in purchasing one down the road once I have it all sorted feel free. It would be no more than $300 but I still have to factor in the final production costs. I'll be making another video as well to announce it
@@analoglyfe I'll follow along and wait to support you then. Congrats on developing a really neat part.
@@KGB908 thank you I really appreciate it
@@analoglyfe Hey could I have the drawing file for the flanges? My email is evanhuang117@gmail.com
@@FIN0LKI11 sure, what file type?
how do you measure intake air temperature?
I have the stock iat sensor sitting in the general area of the filter. Not really mounted into any tube like stock but it just sits there
Can you live with it? (the noise) :D
I couldn't live without it 😍😂
What bore size are the R1 throttle bodies ?
The throttles themselves are 45mm but I was using their rubber boots which necked it down to a 42mm bore size
@@analoglyfe Many thanks Ethan, great project. I have been toying with the idea of doing something similar for a while but to a car not too common, an Isuzu Bellett. 1972.
@@glennp9904 sounds fun! Best of luck!
Would you sell a manifold Adapter? I will buy it
I'm currently in the process of making some. I plan to have the first part in my hands in a month. I do plan on selling them soon after that. I'll come out with updated videos as time goes on
Your induction is really impressive, but the bodywork on your car is not so good
Oh yeah the bodywork sucks more than the induction setup but beauty is on the inside 😉
👎🏼
I didn't hear a thing.. 👂
😑
Does this mean the video doesn't have audio? I'm not sure what to do about that unfortunately
@@analoglyfe I could hear you fine, but as you said, they make no power. So, why would anyone do it? Because it sounds cool. (plus throttle response) Start the car and let your audience hear what it sounds like.
@@iliveinthewoods ah ok, I made separate videos for the sounds. But I appreciate the feedback
