- Part 1 of my guide to fitting motorbike throttle bodies to a car engine as I do the same, trying to do it as cheaply as possible! I go through each activity and decision to show you how!
I fit Honda Fireblade throttle bodies to my autotest mini with a 1600cc Vauxhall engine to get the BRARP BRARP noise and, if we get it right a bit more power, MO'POWAH!!!!

Hello from N.E. Italy 🇮🇹 (an expat married to an Italian lady ;-) and YOU my friend have just given me a great idea!! I’ve an ‘01 2dr Fiat 1.2L Punto ELX I bought from its og owner…my mother in-law!-) It’s done 160k and has served my family well. It’ll be my 3rd car in the stable so now I can mod it. It’s 860kg (light by today’s standards) corners very flat, and really revs fairly quickly up to 120kmh (fine for non ‘A’ road running). THESE ITBs however I think will be the secret sauce!-) Reliability, lower cost build and retain the ability to pass bi-annual inspections 🤓🤩🥳
The algorithm has delivered me a channel I wish I found a long time ago.
I wish I’d started the channel years ago! Thanks for watching and stick around... there’s plenty to talk about! 👍
Me too man
All hail the algorithm!
Praise be to the algorithm
Another vote for a video on fusion 360, designing manifold basics
Excellent! You have spoken! I have a couple already in the pipeline but it’ll go on the list!
Fusion360 for the win
You can use PVC waste water pipes/wlbows to make a prototype on your engine, they're cheap and easy to put together. Also work great for prototyping exhaust :D
I will have to do a new exhaust manifold when I move the engine, that’s a great idea!
Suggestion!! Cut the pipe into segments like what you can get from the pipe, stick them on a piece of foam tube or rubber hose or something, and you can use that for complex bends with many segments
This is going to be a brilliant project. Best of luck with this difficult engine mod. I’m subscribing immediately, thanks.
I don’t understand much, but pick up a few things every time I watch. Thank you!
I hope you‘ll be succesful with your channel, that’s incredible content. I was looking for some stuff like you’re doing! Especially because I’m into 3D printing and car Tuning!
nice.... I adapted two sets of Hyabusa throttle bodies (off eBay) to a Ferrari 308QV (bought at a Ferrari breaker) that I'm putting in my Lancia Stratos Replica
Easy peasy manifold fab. Each bank uses a Datsun 240Z air box. They Hyabusa ITBs are fitted with Honda S2000 injectors
Nice! Love a Lancia! There are only a few engines that will improve on the Stratos V6 and a flat plane Ferrari V8 is one!
Are you using the gearbox from the Ferrari aswell to keep the engine transverse?
@@MakingforMotorsport yep, the entire transaxle/gearbox assy.
Do you have a build blog or such for your project? Would like to see it.

This is so good!
I need you running an ad campaign for me! 👍 Glad your enjoying it mate!
This was exactly what i was looking for. Thanks
Glad you enjoyed it!
Wish i found this channel sooner! Great information! I am in the proces of installing the same engine in my Mini and would love to use ITB's. Is there any way you can supply me with the 3D model of the intake manifold? Thanks!
I'm on the same path in many ways. Using Solidworks and plan to use the 3d printed prototypes for lost "filament" investment casting. Decided to go cast aluminum for possibly adding boost in the future.
Nice work! Let me know how the casting goes…. It’s on my list for sure!
Just subscribed. I'd love to get a set on a daily 1.4i golf 😅
I'm looking to add ITB's on my 1988 Toyota Camry with a 3SFE, I'm looking for about 190-220 horsepower top end range but more importantly that really nice trumpet sound with the ITB's, im looking for a mid RPM power ban as for the most part it's going to be a touge build for the local touge scene
Holy damn bro, you need to keep uploading videos, no way you don't get hella subscribers in the future.
Cheers Bud, this means a lot! I am working on the videos and I’ve got a big list! 👍
Very nice video. I like to see more how you create the manifold in autodesk. I want to try it my self.
Well i bought my self a printer and i designed my manifolt. What kind of filament did you use.?
love it , be good to get a more indepth vid also what material are u testing with against final one , Petrol melt one ??? , all very interesting , please lets see more , subscribed :)
Perfect timing! Tomorrow there’ll be a video out looking at all the 3D prints which have been on the car all year! Thanks for the sub 👍
Ohhh this is getting done to my Punto HGT
I don’t know you or your car but I can clearly see it definitely needs it!
Fantastic channel! Would love more information about fusion360 and designing the manifold.
Thanks! I am giving it another few weeks and I will call the 3D printed manifold a success (signs are good) and I will do a full round up, including the modelling... 👍
@@MakingforMotorsport brilliant, I was planning to fabricate an inlet from aluminium but I have a 3d printer sat at home.
👍👍 I’ll cover off the making the flange CAD aswell, that’ll be useful for marking out or sending to a laser cutter
Would it be correct to state the throttle spacing from the donor ITB's coincided with the engine you are using? i'm going through this process except i have a 94MM bore & port spacing on my engine. and the donors are 80 MM. It comes around to using the 3d printed adapter to save the day! or seems too, I hadnt realized fusion 360 was free all these years
Great video, I’ve got exactly the same plan but I’m no good at Fusion. Can you show me the steps how you did the modelling?
I can do, I am likely to make a few changes following the test run so I will do a video that covers from the start to the end. Thanks for watching, hope you enjoyed it!
How far away from the throttle blades does the air flow straighten out so it doesn't bias the flow in the intake port of the head?
Yes yes yes we need you to go through the print process what type of plastic whats fuel proof will it break down
Its weird your doing exactly what I wanna do
Synchronicity is awesome
Do an na MX-5 with kawasski zx6r itb's next
Ill die!!!
James, I’ve got you covered with all of it... Apart from the MX5 bit (for the moment 😉)
We're looking to add itb to our na 5efe starlet. Any help massively appreciated
Can you do this with a 2jzge? I’ve been trying to find throttles for my conversion
I want to convert my carburettor to this type of throttle body for my Vauxhall Astra, can it be done?
What kind of filament did you use?
G’day. I’ve designed some ITB’s for my car that just so happens to run a 1.8 Vauxhall 8v motor. Plan was to print patterns and cast both the manifold and the ITB’s but after watching this I’m think about printing the whole lot TB’s included. Obviously some surface will need machining still, I haven’t used cabon/nylon yet. Do you think it would stand up to areas like where the throttle plates close against the bore or would it chew out?
Great work! Video please about Fusion 360
No problem, is there a particular thing you about it you are interested in?
@@MakingforMotorsport it would be interesting how you designed the manifolds from skretch. I am thinking to start with airhorns :)
@@ApexRace no problems, I am planning to touch on the trumpets/horns in the next couple of videos, including talking about the pulse tuning they are useful for!

Nooby question, Does bike fuel injectors work for a car, or can one fit car injectors to a bike trottle body?
I tried Fusion 360 once but I couldn't figure anything out. I use tinkercad for all the things I make but I doubt I could make an object that complex with it.
I will try to fit it from zx6r to my clio 1.4 will see how it will end up
Have you considered printing in pla or something soft and then using the investment casting process to then make a shell around your print using a special slurry and refractory sand then melt out your print and fill with molten aluminium?
I have considered it, watched multiple videos on it and put it firmly on the to do list to play around with but if I can make it work with just fancy nylon that preferred in the short term....
@@MakingforMotorsport I’m hoping to try it myself. I’m sure it’s not as easy as it looks. I wanted to ask, is there and book or place where I can learn about ECUs and function etc etc from start to finish, a definitive guide so to speak as I really don’t know where to start and know it’s going to be an essential part of anything I do and unless I’m able to build/program myself I’ll be severely limited in what I can do.
Your voice is quite soft while the music and such is loud, What I really want to hear is your voice. This is good stuff and I don't want to miss any of it. Fusion 360 changed and I have lost vast amounts of work due to their lousy clowd storage and removal of any useful storage local file types. I tried design spark, MUCH easier to learn and free as well with local storage. Too bad, I liked fusion... I am interested in how well the printed parts hold up under the hood in real world situations and how well the prints hold together. I have been using bosch K jet injectors, an all mechanical system they used on vw rabbits and can support around 200 HP. It has lasted 30 years. The intake runners were made from white drain pipe and the fuel lines are steel wrapped ptfe line (do this at your own risk!) The K jet can build 190 psi fuel pressure if something goes wrong and everything has to be able to hold up. Fire suppression is a must. The engine bay needed a paint job anyway.
I like the K-jet, I’ve played with some Mk1 & 2 Golf/Rabbit... I’ll have a look at Design Spark, not heard of that one! And I’ve bought a much better microphone since this video 😉
I'm a bit conflicted about going the ITBs road since my gameplan involves turbo at the end.
Although I think I will just do everything since I want to learn that stuff. I can always create an inlet for a turbo.
If that's what you are planning I wouldn't go on the itb route, there are some serious disadvantages when using the both of them together, I'd research on it a bit more if I were you
These are for example, longer intake runner length, more turbulent airflow near valves (which might not matter much or at all in some cases), sensors can make incorrect measurements, extra weight, complexity and costs
How long did the print take?
Will the 3d print stand up to the heat over time? Have you considered using the 3d print to cast an aluminum part?
It’s a great question and where most of my thoughts have been. I have a couple of plans, first I am just gonna give it a go with nylon to find out, then I may try some Polycarbonate as a spacer plate which has a higher usable temp, 3rd option is exactly as you suggest, but casting isn’t something I can do... yet!
A lot of OEMs use plastic inlet plenums, so if equivalent materials are available, there's no reason why they shouldn't work as 3D printed pieces.
Hi Emma, they do and Glass fibre Nylon is a common material but it’s the how it’s made that’s the difference, injection moulding gives much better strength characteristics than 3D printing and there are many blends of Nylon, some are more temp resistant than others...
All that said, I am with you, it should work, and if there are issues we should be able to design around them! Only way to know, give it a go!
I thought of going down this route many years ago but was naive at the time not knowing how the ignition would work with the setup. I actually went and bought a set of R1 carbs but never got round to do it. I still currently have the Astra GSi XE, And would love to fit the SBD throttle bodies but the cost man! How much would your R1 setup costs and what power gains? I have mildly tuned the XE, so the SBD Would definitely take it well over 200bhp. How about the R1 gains? I’m not very familiar with how the ignition works with carburettors. But the SBD straight to head kit includes ECU standalone and will take a standard 150bhp up to 208 according to dyno runs. Mine has to be 170 with its current cams and inlet and exhaust modifications. Any thoughts? 3.5k on a specialist throttle body kit, or half that price on R1 carbs?
Aaahh the C20XE 😍😍😍….
A hell of a lot of work has been put into those kits so they just work, and if the engine is healthy, then the power is pretty much guaranteed (bear in mind, it probably requires a different exhaust manifold as well, which you have to make or source to their design).
But it’s not witchcraft, and the well designed manifold with the R1 carbs or other motorbike ITBs Will free up breathing which will make more power (and a great noise as well 😉).
Which would I do? I would do the bike throttle bodies. Because I have done it before and I have the means to do it.
Which should you do? That depends on money, ability to have the car off the road whilst you develop it, practical ability to get it done or have someone do it for you, Do you want to faff about with it?
Plus the elephant in the room of how you control spark. When you take away the airflow meter your normal ECU would use?
What would I suggest? Have a look at Bogg Brothers or danST as they’ll both do inlet manifolds for the engine will guide you to what carbs or throttle bodies are right (or make them?) and look at what ignition system makes the most sense for you (I ran my speeduino in spark only for awhile)
Best of luck , let me know how it goes👍
I also want to install an ITB on my engine. I also made a common ramp for each runner for the idle control, but I don't know where to drill the runner? Does it matter?
Hmm... I have never had to change that, but had a think and I would likely keep them close to the injectors and butterflies. If the connections are for idle air then it will provide some mixing, if for MAP it will give the smoothest pressure signal (especially if you have an aggressive cam) so needs smaller plenum.
Best of luck with your project! Let me know how it goes!
@@MakingforMotorsport I think so too, thanks, I'm waiting for the next video. I hope you show all the stages of the assembly! And while I wait for the summer (
with direct injection it would be even easier right?
If I have a two litre engine, would I have to get throttle bodies that match a 2000cc bike? I'm assuming larger engines have their inlet ports further apart?
Port spacing is always a problem as bike engines by their nature are generally smaller but it shouldn’t be main driver of choice, that should be airflow and therefore the diameter..
Generally power = airflow through the engine so picking throttle bodies off a bike with similar power to that which you want to achieve is good starting point... if from that pool you can match port spacing for straight runners then bingo, otherwise you’ll just make up the difference in the manifold as smoothly as possible...
I think you're matching the power rather than the engine capacity.
I would love to see the cad design process
I am going to roll the inlet manifold design process into the velocity stack video aswell so I will cover both of them off at the same time 👍
So.... what you're going to do with crankcase ventilation ?
Hi, the crankcase (and head) vent currently goes into a catch can (old water bottle) and the then atmosphere, ‘cus it’s not a road car I don’t have to deal with any emissions issues 👍
How do you adjust your idle and where you attach a map sensor
The idle was just adjusted on the stock idle position for the ITBs…
I know I'm late to the conversation but I would like to know more about how you make the intake in Fusion 360. I already use this program at work. Maybe you could share the model as well? lol
Hi there, I covered the principles pretty much step by step, but it’s all very low level modelling because I am not very good! 😂🤦♂️

Hi, this itb Is for 1.0 engine but Is good for 2.0 liter engine?
Pretty much, it’s all about airflow and remember, that 1 litre engine revs to 13000 rpm and makes 170bhp! Airflow and Bhp are pretty much directly related so it’s as good a guide as any!
Can you post a link to your laser cutting guy on Ebay, much appreciated

Nemoj legendo stavljati ništa na taj motor, blago rečeno je đubre od motora. Ništa snage nećeš dobiti samo sa itb-ovima.
Bolje ti je da nađeš i ubaciš m20 motor, uskoro u Srbiji nastupa novi zakon gde je motor zamenski deo pa će takva modifikacija biti dozvoljena. Cena projekta ti je otprilike ista, a m20b25 ima 170 konja, i uz pomoć turba gura 300+ lagano.
P.S. BMW M50B25 (193ks) paše savršeno na menjač od M20b25 ali je to malo teže za legalizovati u Srbiji, verovatno bi morao na Mašinski fakultet po atest neki. Po meni dosta bolji motor od m20, ako ti je kocka drugi auto isplati se malo muke. Čak imaš i opciju da ubaciš radilicu/klipove iz M54B30 u M50B25 i da bude 3.0 bez da iko osim tebe zna. I pumpadzije naravno, takva mašina lepo troši.
@@lazar2175 Hvala na komentaru. Razmisljao sam i o turbu jer sam video po netu nekoliko njih al nema sanse da prodjem tehnicki sa tim, vidim da ce morati da se ubaci m20...
@@user-wm7gu8zi9n Ma prolaziš tehnički sa turbom, jel stvarno misliš da kod nas na tehničkom to zagledaju pod haubom. Ako ne viri turbina iz haube prolaziš 99%, ima onaj lik iz Novog Pazara Opel Corsu sa 1350ks i registrovana za street race zamisli.
Nego se ne isplati stavljati turbinu na taj motor, ne možeš puno konja da izvučeš a koštaće te boga oca i kvariće ti se jer obično to tako bude sa budzenjem turbina. Pre godinu dana sam sklopio e34 525i turbo za drift, to stalno curi ulje antifriz pa zajebava mapa, nema ko ovde da tunira dobro itd..
Na kraju skinuo turbo kit i prodao BMW za smešne pare, čekam neke srećnije dane da imam svoju garažu pa da radim to natenane.
Za kocku ti je najbolje rešenje m20 motor i menjač, to je relativno teško naći kod nas ali nisu skupi, za par stotina eura se može naći neki ok. Isto ti treba i diferencijal, kardan i nosači motora, zajedno sa kompjuterom.
Najveći problem je struja, dobar auto električar će te ošuriti da ti poveže sve to i da ti pritom sve radi kako treba, ali ako se malo razumeš u elektrotehniku možeš i sam to da uradiš.
Sve u svemu, treba ti oko 1000 eura da ubaciš m20 i da završiš papire sve, ako radiš kući sam ili sa ortacima. Majstor bi verovatno uzeo još 200-300 eura za ruke.

Is it a Vauxhaul Cavalier motor?
It was in the Cavalier, the 1.6 would’ve had an older version of this engine, c16sv maybe and this is the z16se which I have is a modern equivalent with some emission bits in it…
This is not to be critical ,it is an observation based on collective information gained and peoples mistakes that were rectified.
From what i've learned so far from triumph spitfire forums on EFi conversions the TB needs to be matched to the intake tract of the original,spitfires using twin SU HS4 carbs switching to individual TB or single TB and plenum that have a throttle plate/choke size that is too big,get all pedal response in the first few cm even mm of pedal travel,the TB used here "look" a bit big,though choke sizing as per weber carbs would restrict air flow to a wider pedal movement/throttle range.
As for the fabricated runners for non 3D printer makers,you can use aluminium tube bends or straight tube as per need,and need not weld;hard soldering rods wrongly called aluminium brazing rods(soldering process expands parent metal pores to fill with filler rod medium,whether lead/tin ,brass or ally alloy) this method seems from what i've seen on youtube to be more than strong enough,all tubes need to fit inside flange plates for max strength.
I'd like to tig or mig weld the ally but pure argon is not cheap,and as only a blow torch that can heat to 700 degree C is needed and a stainless wire brush,a whole host of ally goodies can be made now,even fill in rivet heads and smooth to look like button rivets.
If i can get a few of the disposable argon bottles for the gas/gasless welders i can tig or mig,only if i can get it cheap enough though and i am still biased towards the hard soldering with a small head torch to minimise heat spread distortion.
Are these reliable? Compared to proper itbs.
Well bikes manage well with them….
"is a Honda reliable?" Asks the man with a French car.. sorry we always had this joke about French cars at work..
Could you have sent the final manifold design off to a metal 3d printing supplier?
I could have and I'll be honest I don't really know how much it would cost, but it's likely more than I'd want to pay 😂 (but I am cheap!) I might get a quote at some point just to know....
Hello. Great work, but I guess you can face some problems with 3d printed manifold I guess. There could a problem with layers overlaying during printing and you can get a lot of leaks of air through layers. I`ve seen almost the same situation in ruclips.net/video/Qu79vUbcXCU/видео.html (timing is important). Just FYI. I`m not experienced with 3d printing.
Hi, just watched that video! He’s doing great stuff, thanks for the link! He is using a different 3d printing tech than I plan to, I will use FDM (Fused Deposition Modelling) with Nylon but it’s all an experiment so we’ll find out together! I have my tests done and bought a couple of the bits I need so I am about to start putting it all together!
What about using the 3D print as filler with 1 layer of CRP inside and out? That would be surdy and heat resistant. Not to mention light.
@@edwincolon7782 it’s a great idea, I did think about coating it in a resin or something and just using the print as a buck or former, and there are plenty of epoxys out there which will do it, I am just trying to work with what I have at the moment. Honestly I don’t know if it will work but I am happy for it to fail but I won’t give up! Thanks for watching, I am working on part 2 now!
@@MakingforMotorsport Hey mate, great video!
I'm in the process of installing a dual carburetor on my Opel Kadett C 1.2L. I 3d printed a manifold I designed out of PLA and plan on casting it in aluminium using the lost PLA casting technique.
