- Part 2 of my mission to fit motorbike throttle bodies to my Vauxhall engined Mini. I go through every single step from trial fit to start up so you can do it too!
PLEASE BE CAREFUL WHEN TESTING INJECTORS! Loose petrol is very flammable, and live switching the pump can generate sparks - you can see my extinguisher - I had 2! If you have a leak or spill mop it up and come back another day.....
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!!!!

Sr. This is one of the best DIY motorsport channels I've ever found! 🍻
Thanks well very much for saying Rene, it’s fairly early in the channel and we are growing the community so comments like that are great to hear!
I hope it helps you go out and get faster times and bigger skids!
@@MakingforMotorsport Agree I'm trying this
And its invaluable to have this UA-cam as a reference
We love you Rutger hauer
This is incredibly underrated information. Thank you for sharing this. This idea opens up so many options for small 4cyl engines.
They have a couple of downsides but if had to pay for “proper” throttle bodies, I couldn’t afford any!
I designed a manifold adapter for a Mikuni hsr42 to 3 bolt turbo intake to use on my corvair engine. 3d printed it and then sand cast it in aluminum. Just got the surfaces machined flat and some of the mounting holes drilled. Thank you for posting this it really helped a lot to keep me motivated and moving forward after a few initial setbacks!
This has got to be the best motorsports channel on youtube. This video series inspired me to give motorcycle ITBs a shot on my Miata instead of just upgrading the stock intake setup.
I'd be interested to see how you implement air filters in a future video.
Thank you, I am quite sure there are better channels but if I am demystifying a few things that’s great 👍
And I’m looking forward to working out the air filters too! 🤷🏼😂
I'm building a MS1 2.2 on my car and these videos are being great help with the little details. Thanks!
The car's luxurious interior was eye catching...just lovely!
Love the video...😁👍
best feeling ever. have exact same set on my datsun 1400 , just smaller blades. nice work
Absolutely brilliantly done, very cool video and giving me ideas for my printer
One of the best Video Series i found recently.
Highly underrated channel. Keep up the good Work !
Great to hear, it’s comments like this keep me making videos! Thanks a lot!
Awesome now my love for Itbs, 3D printing and 4 cylinders have merged into an amazing video. How is this channel not any bigger?
Great work can’t wait to see more
Cheers! A full throated 4pot snorting through ITBs is a beautiful noise!!! Got lots of ideas for videos... and one uploading now! 👍
My goodness I wish I knew about this channel so much sooner!
amazing... from brazil ! love your videos and i have a opel kadett 2.0 8v c20ne to
Have to love ITBs on a 4 banger! Reminds me of my old MK2 Escort with twin 45 Dellortos!!
There's something way more interesting about channels like yours where everything is made to a high standard or tested but using low end fabrication techniques. Probably because it feels closer to the average DIY'er :)
Thank you very much…. Everything I do needs to be do-able by my audience…. At least that’s my philosophy….
The idea of doing this to my 1.8L corolla is really gojng through my head. I plan to do some other stuff to make it a little more fun on the twisty roads.
Autotune is your friend for first few start ups. Great Job friend.
Thank you for taking the time to make these videos - this series is particularly interesting as it is something I am looking to try myself to replace a rather shonk steel fabricated manifold. I am very interested to see how the CF Nylon deals with long term exposure to petrol.
Glad you are enjoying it! I am spending a little time working out a few kinks so there will be a few pointers for anyone planning to do this. And I currently have a lump of of the nylon soaking in fuel so we shall see....
Nylon should be our best bet for this, my stock intake on my m52 is made from glassfiber reinforced polyamide 66 and is now 25 years old :)
Iam interested if the CF-nylon (propably some blend) filament is close enough to pa66 in chemical resistance :)
Great vid! excited for the tuning part, the speeduino engine management has me interested!
Looking forward to the tuning myself! I'll make sure I pick up on the Speeduino....
used the same engine(only much smaller capacity &turbo charged) in a nova for hillclimbing for many years. the inlet & exhaust manifolds were sealed no gasket and just a thin skim of silicone with no trouble. o rings will work but can fail.
Nice stuff!!! You definitly get fun doing it, it is clear!! I'm planning to do something like that on my mx-5 already power by speeduino. Thanks for the input!
It keeps me busy! The only thing I love more than modifying cars is driving them! (And Wife and Kids, obviously 😬)
Very informative and your a Genius. Keep it up Sir. Now that a Passion ❤️
XD I've got a pair of CBR1000RR throttle bodies, complete, with injectors, sensors, all that jazz for under 100 bucks (I bought them something like 5 or 6 years ago). Been needing an aluminum welder and some pipes to make myself a new manifold to mount it to my car. Once I get some sensor plugs, it'll be a plug and play deal on my integra. Just need to make myself a vacuum manifold. Honda parts are great. Even the TPS sensor is exactly what's needed for my old integra to run them. Heck, even the throttle cable hooks right up, no issue. It just needs a small bracket to hold it in place. Mine's the early model from 04-05 CBR's
More itb videos. I got a 1992 celica st with a 20v 4age swap with open ITBs, they sound so good.
OEM’s mainly use nylon 66 which is a glass fiber filled nylon plastic, lost core molding is possible for one piece complicated designs. It is Strong, Dimensionally and heat stable, can be friction/ultrasonic welded and accepts heated brass inserts for threaded fixings well.
Hey mate, just discovered your chanel and I'm quite enjoying your work :)
I thought I might be able to help with a couple of suggestions; the big difference between high and low impedance injectors is that low impedance were originally about shortening the transient time as much as possible. These days a lot of this stuff is characterised quite well in OEM computers, so doesn't matter as much, but you can actually use your characterisation rig to do the same thing... Just run the injectors for 0.5ms on, 10ms off for a minute or two, then 1ms, then 1.5ms and keep going until it graphs out to be a steady state flow rate. That can be fed into the ECU to correct it and that'll help a LOT with idle tuning.
With regard to the cable travel stuff, have you considered just changing the ratio at the pedal? That'll get you the ability to tune the throttle travel to get the effect you want. You can also replace the throttle cam (on the throttle body) which will give you the ability to map the cable travel to throttle blade travel in a way that makes you happy as well :)
about 6 months ago I designed a manifold in CAD for my 106 xsi. I never produced it cause of the material. In the end i was going to go with a pa11 nylon but you have taught me about the fibre reinforced nylons so i'm going to look into that now
I am not quite ready to declare it an absolute success but I was out tuning the car on Sunday and the manifolds performed really well...
If you can find high temp CF nylon like that from eSun or Essentium rather than the ePA from Sainsmart then it would be even better
Great video and very informative.
But if you where making a itb set up for a V6 what bike itb would you go with?
Love your work and information.
How did you set the idle?
Through tuner studio with speeduino there is a test screen for testing your injectors too. I believe you can pulse them at a duty cycle as well.
Did not know that! I will have a bit of a poke around... in fact that would make a nice little project to do a custom board with a spare arduino... 🤔. Thanks for the heads up👍
Great project and explanation! Really enjoying the content. I'm currenty making something similair for my mk1 Golf, but do you still use the Honda Idle control valve? My guess is that you won't need is anymore but I'm hoping you can help me out..
Keep up the good work!
Kool video🇦🇺🤜🏼🤛🏼🍀😎
The skies the limit with 3d printing.
Interesting video. I'm in the process of converting an air cooled motorcycle engine to fuel injection. I was planning to use the forged carbon fibre method for the intakes using 3d printed moulds but I might have a go with the carbon filled nylon, depending on the price of course. My only concern is the cylinder head temp on an air cooled Vs liquid cooled. I might cut a gasket from some ptfe sheet if necessary. I suppose I can also use tophat style ptfe heat isolation bushes around the fasteners. My biggest concern at the moment is the rotor for the crankshaft sensor. I'm using triumph tt600 fuel injection parts and I don't have enough space for the standard rotor so I'm going to have a go at machining a scaled down version. Good thing I have a CNC mill. Wish me luck.
LOVE your shirt dude!
Cheers! The wife got it me!
Love your videos!
Cheers bud! Love your comments 👍
Good to see a great Aussie innovation - the Speeduino in action. I've go one on a 125cc scooter. Great video series with heaps of ideas. Can you tell me the overall width dimensions of your Vauxhall engine - I'm assuming its a Corsa motor. I have an aussie kit car called a Pellandini which has a classic Cooper 1275 in the arse of the car. The Cooper is great but I'd rather a modern twin cam without tge eye watering expense of a a-series aftermarket 8 port head coupled with running the engine lubricant through a helical cut gearbox.
i'm just speechless for ur effort bro, u've just made me buy speeduino for try installing it on my fiat punto gt 1.4 turbo. My ex-co worker told me it should be 1 little vacuum pipe each cylinder instead of 1 bigger on 1 cylinder only, cos of compensation of the air it sucks. Just asking if u agree on this. Keep goin bro!
Great videos love them, helped a lot past month. I'm doing same conversion on my 4A-GE corolla. Only issue I have is throttle pedal path, can't get more then 2-3cm from full closed to full open throttle butterfly :(
Cheers Bud! I have the same problem with pedal movement… currently working up a solution with a stand alone drive by wire!
@@MakingforMotorsport thanks for answer :) glad that you have solution for that, I want to solve this issue without any electronic components. think I will try by putting a bit bigger throttle rotor
This is awesome :) i just received bmw k1200 throttles for my m42b18. I also plan on using nylon for a custom adapter from the head to the itbs. Looking forward to your next video!
I should have it out in the next weeks, but it's all going well so far. I used to have an E30 318iS with the M42 engine, it was great! Love that engine! A E36 318ti is next car on the shopping list so I'd be interested to know you get on... let me know!
@@MakingforMotorsport yesterday i completed the proof of concept, all printed in petg. Still running all the stock sensors, printed an airbox for the AFM, vac manifold etc. After some Vacuum leaks trouble it ran and got a stable idle. I did a couple of short rips up the street with everything cold so the petg doesnt soften and it ran as good as stock, really pleased with this first result :)
For the throttle movement i designed a rotary coupling with the correct factor to make the pedal throw fit the itbs :)
Next iam starting to learn printing the polymaker pa6-gf and make the manifolds in proper material.
Looking forward to an update on your mini! First drive maybe?
Fantastic work! Great to hear they are working well and I like the sound of that filament, I must check it out! Using the AFM and a plenum with ITBs is a great OEM solution but I’d be interested to know if you get a noticeable improvement in performance without a remap, let me know!
I’ve had my car running and driven hard on a mapping day and the nylon induction manifold worked faultlessly (and sounded awesome), the update would already be out but the Speeduino video has blown up so I am following that up. I have an event in 2weeks so there will be an full video following that! Well done on yours tho, keep me informed! 👍👊
@@MakingforMotorsport ua-cam.com/video/tHUrcE-snic/v-deo.html
Progress is slow right now, but it was awesome to see your setup in action! Gives me motivation to go ahead faster! :)
Great channel and great video! Subbed
This is an interesting series. I did the medium (to high) cost method to put ITBs on a 3SGE beams in an Altezza using 'off the shelf' bolt on parts:
- Throttles from a 4AGE blacktop (Imported from Malaysia).
- Adapter plate for those throttles to the engine, along with some throttle pulley changes and velocity stacks (All from Australia).
- Link plugin ECU as the Altezza uses a weird internal protocol and I wanted to keep my factory dash working.
- Wideband O2 and lambda controller
- IAT sensor
- Pipercoss filter
- Baffled catch can
So all in on my spreadsheet, it cost £2,796 including tuning by a specialist garage.
An ITB kit for this engine costs £2,400, and with ECU, sensors and tuning needed on top of that it would likely cost over £4,500, so I did save some money compiling it myself.
The noise is worth every penny, and the stock Altezza throttle is really laggy as it is partially DBW so it feels incredible now it is entirely cable driven. Unfortunately covid put a stop to planned dyno sessions and track days to test the change in performance.
Wow! The full package! I haven’t played with BEAMS engine but they look really good, did it respond well to the ITBs???
If you want to stay stock with the car and go with ITBs it can be tricky as cars are so integrated now (ECUs running alternators etc...) so I am not surprised you needed an extra box of tricks, especially as a daily driver... did you have any problems or did it just bolt up?
Hopefully you get back out on track soon so you can enjoy a little BRARRPP!!!!
@@MakingforMotorsport Sorry I didn't realise I didn't have comment notifications on, didn't see the reply!
Everything bolted up fine until I wanted a big air filter. The sock filters got chewed up when it was being tuned and I wanted some protection from the worst particulates going in. I ended up having to remove the attached reservoir, grind off the mounts and pipe it to a reservoir elsewhere.
The engine feels so good now in comparison. I'd love to see how the dyno graphs have changed (hopefully in the next few months) but it feels incredible. It does struggle when cold as I have no IAC but as soon as it is up to temperature, it is spot on!
It would be great to see before and after but if it’s made it into a different car then you’re already getting the benefit! 👍.
I am making no allowance for idle control, my first 3 cars needed constant blipping when cold so this will be quite nostalgic!
Brilliant video. I’m planning to run my xe with Hyabusa throttle bodies wit a Speeduino so my eyes are peeled.👍
Thanks for watching... the Speeduino is a great option, cheaper and easier to build than a Megasquirt and it’s been 100% reliable... even with my soldering!
You’ve gotta love an XE! What car is it in?
@@MakingforMotorsport It’s going in a escort mk1 with a Mazda RX8 gearbox.
@@DylanWilliams-qk8sj I am green with jealousy! I had a Mk1 running a YB and silly boost but sold it for a house deposit (the most sensible bad decision ever made!) I keep trying to talk the missis into buying another but they have doubled in value!!!
The YB was silly but free breathing XE would be beautiful choice! How are you mating the g’box? Are there conversion bell housings?
@@MakingforMotorsport i have bought a adapter plate that works really well.
I’ve had the car for 15 years .
I didn't know you could just swap the 5V/GND pins to flip the output of the TPS - thanks! I also 3D printed some adapters to fit bike throttles to my car, running off a speeduino ECU, so it was cool coming across this video.
No problem, glad I could help! Nice to hear people using 3D printing for something other than vases!
Love the channel so far, exactly the kind of content I'm looking for.
Also would genuinely like to know what's going on with that alternator wiring? as I'm in the middle of something similar.
Excellent! Good to hear it’s hitting the spot 👍. The alternator wiring is a good one, the alternator is from a Daihatsu Charade (Vauxhall was was too big and heavy!) but it is a fairly standard Nippon Denso item so just needed to get it working! If you’ve got a specific questions just let me know...
Same thing. Got a twin leg Denso with a three pin plug but the old unit was two pin plug. Guess you just completely disregard the extra pin in our case?
I don’t use the 3rd pin on the low power connections. I pretty much followed this for the “Four connector a”, I think, I will check after work. 👍

This answers every question i had😅
thanks 👍
Great channel, very interesting.
Cheers buddy! 👍 you keep watching, I’ll keep making them!
I am working on doing this for a classic car V8 and this has answered a lot of my questions. Excellent video thanks. PS What bike were these from?
14:27
you can built a simple converter chainring like the gears on a bicycle to multiply and reduce the cable run
Great video mate I’m now convinced but I will buy a built board 👏
👍👍 thanks a lot! Fair enough if you want to buy a built one, don’t blame you at all... but gimme 2 weeks and I’ll show what it takes to make one!
Ok I’ll sit tight 👍
His laugh at the end , hell yeah
love the idea will try doing it my self but my main concern is wont petrol damage the 3d print and warp and melt it and second is the heat from the engine as i am planing for an aircooled engine which gets crazzy hot any help would be appreciated
Hi 👋 how do you find the vac with a single take off ? Would have presumed you would have taken 4 into a small vac tank and came off that to the servo ? Does one work ok with the single one ? Would assume it to pulse abit or alot lol
Love the videos! Subscribed and following. I'm going to be doing something similar in the future for an old motorcycle. Do you have a favorite software for sizing o-ring grooves?
Thanks for the sub, glad you are enjoying them! I didn’t use software for the o rings, I just did abit of the google instant-expert, found a data table and used that, I reasoned it’s just vacuum so not ultra-critical. I used this www.row-inc.com/sizes.html
@@MakingforMotorsport thank you. Something else that I was thinking about, it might be nice to see how fuel resistant that particular nylon filament is.
Did this same thing a while ago with my civic, made my ghetto manifold with aluminum tube and scrap plate
Great series. How would you go about increasing the pedal travel to cable pull ratio, to make it a bit easier to manage with the reduced travel needed to fully open?
It's a great question, I've just done an event in it and I am planning this as I type, once the next couple of videos are out expect to see something!
I have been working towards putting ITBs on my Imp engined Ginetta G15. I picked up some kawasaki Ninja ITBs a few years ago for £45, and was planning to fabricate an inlet manifold, but then an Ender 3Pro came my way, so found the information on upgrading and printing carbon fiber nylon very helpful. I have drawn up an inlet manifold that I am quite pleased with so far, it fits my spare head and looks awesome in my opinion. I have also modified a Lucas distributor to remove the advance/retard so can be used as a cam sensor and drawn up and printed a prototype Distributor cap and vane to us with a slotted opt. Speeduino and stimulator are build up and seem to test out ok.
Thanks for your work
Peter
Wow Peter, we are just peas in a pod! Same printers, same plans! Except only one of us has the best car! You don’t see many G15s about! 👍👍👍 let me know how you get on! I am tuning mine this weekend 🤞
@@MakingforMotorsport I'm very interest to find out how durable the inlet manifold is
printing parts directly to car would be awesome, nylon can do that i understand? first i need to move to the new garage and build an enclosure that i need so much :D
Found your channel yesterday. Love the content. What is the racing you are doing in the mini called? It looks like a hoot!
It’s a strange sport called autotesting, I did a video on it, but in a nut shell it’s precision driving against the clock, low speed, high skill and low cost. It’s one of the few motorsports with very open rules so I am free to create Frankenstein’s monsters like the mini! 👍
@@MakingforMotorsport ahh, because the name is so generic I thought you were just saying you were going out to test your car (autotest) thanks. As I am making my way through your videos I am now really tempted to create my own intake manifold
Really nice channel with super informative videos. After watching your videos, i decided to buillt my own ITBs with some motorcycle ITBs.
Only question i have, how can you control your idle speed?
There are several ways, my ITBs came with an idle control actuator that was vacuum controlled, so you could use a PWM valve to control that. Also you can build a bypass valve and pipe that into the runners after the ITBs... but my car idles okay without anything (I’ve not tried it in the winter yet!)
@@MakingforMotorsport Does that mean that your idle is managed by a mechanical system on the ITB assy. without any interferance from the ECU. I am planning a ITB build this winter, and idle strategy is what puzzles me the most. I am planning a more "street oriented" build, so would like decent idle control at a larger temperature range. Is there some specific ITB's that are worth looking at to get those systems as "part of the package"? Looking for a set of bike ITB's between 32-36mm
Any concern about the fuel corroding the plastics and having it fail?
Great video! Have you considered the effects of gasoline on your 3D printed materials? Also any CFD analysis or are you just going off of best judgement?
Hi, saw your comment on Reddit, thanks for watching! I did research for chemical and gasoline resistance and nylon is one of the best but 3D printed it might be different so I have a stress test at going now and I am soaking a section in gasoline as a qualitative trial.
I didn’t use CFD just good practice and judgement, the 3D printing is a technology trial as much as anything, “what do you need to do get it to work?” Iterative optimisation would just complicate it at the moment. But once all the kinks are sorted it’s a great idea for a study!
Awesome stuff, new sub for you 👍🏽
Cheers Slim!
Very inspirational video! If we connect vaccum from all TB don't we kill the individual term of the equation? I mean speaking about the interaction of pressure/vaccum that happens on each throttle body at different timing.
Maybe not if there's no valve overlap!
Thanks again for the video.
Yeah, you are after an average across the cylinders and across the engine cycle, on a high overlap engine this becomes very hard because of the pressure spikes from reverse flow at low engine speeds.
That said, I only really use MAP for information, as I run pure Alpha-N 👍
I know nothing about bikes, is there some year model I should look for, or are there a particular version of Fireblade throttle bodies that you used?
I'm trying to source some throttle bodies now I wanna try and keep the stock ecu. So I was wondering would the fuel injectors that came off the cr firebird fit my wiring harness or would I need to add new fuel injectors plugs
Hmmm… possibly?? But probably not. Depending on the type the connector will or won’t fit, but that’s no an issue as they can be bought and swapped out, as long as the resistance on both types is similar 8-14ohms then electrically they should work…
But the bigger problem is likely flow rate, it’s highly doubtful they are the same, so even if you can use the same ECU (which also has some issues), then the ecu won’t be adding the right amount of fuel, standalone is really the way to go here…
Check out my video on the Speeduino for a full standalone for not much money 👍
@@MakingforMotorsport should I go for a 0.4 or 0.3 board if I'm keeping most of my harness intact
Another proper video
Thanks! Glad you enjoyed it!
Excelent my dear friend
Hows the alpha m working? Wouldnt it be better to make a little vacuum pot and run all your vac lines through it?
Hi there, I have no problems with the Alpha-N. Where is becomes tricky is when you have an extra idle valve, as the ecu cannot track that extra air.
So for my competition car alpha-N is fine. If you want a perfectly behaving road car for winter and summer, alpha-N (and throttle bodies) might not be the way to go….
Great practical content. Sub'd.
Thanks for the comment! Welcome along!
@@MakingforMotorsport Great choice of car platform. I've owned a '71 clubman and an '04 MCS and am rebuilding a zetec for motorsports right now. Literally ordered the NylonX with the same intake idea just before watching your first video on the topic.
Good to hear you trying manifold, I have had a couple of issues I am trying to sort out with it, nothing critical but just takes time, it’ll all be in the next video on the topic...

Quick question, dose you ecu manage spark only? looking to run a coil pac engine on old individual bike carbs.
Love the vids, really interested in the 3D printer and what they can do for us in a motorsport environment.
I was running spark only with the Speeduino for a year or so, in combo with bike carbs for simplicity…. It’s very simple and needs only throttle angle and crank trigger, especially with wasted spark…
@@MakingforMotorsport how did you overcome the throttle angle sensor? looking to use a set of carbs off a gpx 600 r and does not run one.
When I picked the carbs I made sure that I got one with a TPS, they all work pretty much the same way…
@@MakingforMotorsport I am looking at the NODIZ, super easy to install and has the option of spark only. Allowing my to optimise the COP set up.
The NODIZ seems like a good piece of kit and definitely a cheap off the shelf option. Naturally as Head Speeduino flag-waver I will recommend that but if your not into DIY then a NODIZ will be easier… (although a prebuilt Speedy won’t cost much more…)
Have you played around at all with "fly-by-wire" with a servo controlled throttle so you can map arbitrary pedal-throttle curves?
Great channel, I've only recently fallen down the DIY ECU rabbit hole and between you and SuperFastMatt a lot of the mystery of engine computers has been dispelled.
Thanks! Glad you’re enjoying it…. I am playing around with exactly that at the moment… in my latest video, which is an event report I come to the conclusion that I need more control over the throttle…. I put it to the audience… DBW wins!
Drive by wire, you're not flying.
I planned to do that but I ended up selling my artillery sidewinder I never opened it, what cad u used? Just fusions enthusiast version?
There is abit more development before this can do reliably for the long term but the signs are good! I am just using Fusion on a personal licence, I’ve used inventor before so it makes sense to me...
How i can calculate this cc/min in a carbureted system? I want to do this with 4 150cc (or more cc's) carburetors (1.6 80hp CHT Engine (same as Renault 12))

@@MakingforMotorsport Had it in a kit car for years...
It's just another day...!!!
I was thinking about using ITBs on a Honda k24 with compound turbochargers like Eric Jarvis did on his high horsepower K24 S2000.
hello can i buy the manifold for vx engine with the normal 1400ccm
the whole oversized injector thing is easy, just drop your duty cycle down, that's what the tuner shops do on haltechs. pretty cool video though!
Thanks! It’s true that you can trim the whole thing up and down with the “required fuel” and that will put the duty cycle up or down aswell the duty cycle gets so small (1.5-1.6ms - and remember 1ms it’s opening so no fuel flows) that it loses precision , e.g the changes become proportionally big compared the total).
I am tuning my car at the moment with the injectors which are too big and it’s running fine, but my idle and emissions could be better with better chosen injectors 👍
14:25 Regarding different operating ranges for car throttles versus motorbikes, how about shorten the "lever arm" on the gas pedal, or if you want to play around, create a "mechanical divider mechanism." The divider would just be a pivoting lever or balance beam, with input from gas pedal on one arm, and reduced-throw output to bike throttle body.
A-ha!!! A very good idea! I am making the final throttle body video now and I will discuss these options, but I will also throw the idea of full drive by wire in there aswell... I’ll probably let the viewers decide... I reckon I can guess which they’ll pick!
Nice, have a c20ne with more or less same setup megasquirt with cbr1000 itb.unfortunately intake manifold is cracked.
Was your manifold 3d printed or fabricated?

Hi bud, how have you fitted a coil pack to this engine. looking to put bodies on my K10 micra and keep running into that issue
Hi, I use wasted spark for this and the later models with these engine had wasted spark coils fitted where the dizzy was. I could’ve used any coil, but as you can imagine, this one just fits as it’s OEM.
Do you need a new fuel pressure regulator for the itb
I didn't as the ITBs came with the fuel rail and a pressure reg so I've just used the current one, gave it engine vacuum and it's working well...
17:02 nice Colin Furze cackle :-))
Nice work! I will be back.
Thank you! If I am half the cackler Mr Furze is I am a happy man! 👍
Great vid and I am designing a manifold in 3d using carbon nylon filament (on the final print).
What percentage of infill is recommended and did you cure the manifold in an oven before using it? Many thx and looking forward to the next installment.👍
I went for 30% gyroid but I thickened up the walls to 8layers, really slowed the print but helps soooo much with point loading strength. The fasteners basically clamp through to the head on solid material and the runner walls are also solid, due to the wall count.
I have had to make some changes (due to the coolant port in the head) but I have had it up to temp and it was going well until it started leaking coolant!
I also plan to support the throttle bodies weight directly to the head on the cam cover bolts, otherwise there is lots of vibration that will likely be an early failure mode. (That’s a sneak peek of basically the next vid!)
Best of luck with yours! What car is it on??
@@MakingforMotorsport Thx for that and I am making a manifold for a Triumph Stag and as a V8 should support the weight of an efi carb.
Also making a Triumph TR6 manifold running BMW S54 throttle bodies so a couple of things on the go
@@MakingforMotorsport I was thinking of making a bigger flange/washer to help clamping force so to evenly clamp it down to avoid too much crush at the bolts on head
A TR6 on M3 throttle bodies and a fuel injected Staaaag, love it! I would love to do a resto-mod GT6 but that’s a few projects away!
Looking at what I have seen I think oversize washers or even a full plate to sandwich the manifold flange would be a good idea as the current flange is showing some deformation. I had also thought of steel “top hats” for the fasteners so the fasteners can be torqued properly without all the clamping through the print...
I am just going step by step so I can see what is and isn’t needed.
Hopefully it’ll work out!
@@MakingforMotorsportyes having some tubular inserts and the viton type seals that you have look great and the way to go and will do a vid as well when closer.
ah... 2years ago... where has this been!!!??? make it look easy enough even i want to have a go... but most likely won't lol
Please Sir, may we have a how to tune the speeduino with alpha n?
Angus, you are reading my mind, I am literally making that video now... gimme a week or so... I’ve got ya covered
@@MakingforMotorsport thankyou 🤙🤙🤙
Nylon glass fiber is the filament to look at. What % infill did you use ??
30% as I recall, but I went heavy on the wall count (8) so there was solid material round the bolt holes... CF-nylon is my favourite filament, I just wish it wasn’t soo expensive!
@@MakingforMotorsport great channel by the way, looking forward to more content
Cheers buddy! Working on it now!
I'm currently working on my 1992 suzuki bandit 400cc (4 cylinder), in order to replace the carburators to EFI. Do you think that I can print the injection bodies with CF nylon? Using the mobile parts of a backup set of carbs that I have. Thanks for reading!
what type of filament did you use to the final work?
I used Sainsmart CF Nylon, its great stuff and has bared up really well and it's lovely to print with.
Changing the ratio of your throttle pedal with a mechanical acc pedal is brain dead easy. Just length or shorten the pick up point of the cable on the pedal that is above the pivot point to get the throw that you need. Its no different than some cars brake pedals from that era that had power or non-power brakes, the clevis pin had two spots it could connect to the pedal to change the weight of the brake engagement.
When testing the flow of the injectors shouldn't they be pulsed like they run in reality rather than locked fully open ?
When cleaning and testing vs specs you would need to pulse to check the open and close time is to spec and there is no leaks between pulses, but I was just interested in the full bore flow rate so that’s why I went fully saturated. To fully test you would test over a range of speeds/duty cycles.
I am still guessing what the opening time and voltage curve is for them, to find that I would need to pulse and compare the values to a calculated value but I don’t think I am far away, a task for another day I think...
How do you think the nylon will hold up to temperature?
That’s the big question! You may seen on a another video, I tried annealing and tested for heat resistance, was very good, 170c plus in my little test.
I have run these up a few times and they have done a few heat cycles and all is good so far... but it’s going to need some specific aspects to make the inlet work long term.
I heard when tuning it s that tune via tps position and map is maxed or something
Yeah, commonly you use Alpha-N (just TPS) because of a variable map signal, especially if there aggressive cams installed with lots of overlap and the lose vacuum with low throttle angles, especially at low engine speeds. This has implications on how you fuel it, which is the main subject of the third video 👍
3d print using ABS Filament?
What filament did you use for flanch to head?
For this I used Sainsmart Cf-nylon. It does the job but I prefer the eSun version of the same that I have used recently
@@MakingforMotorsport is it work without any problem, or deformation? Temperatures are OK with this material? and also mixture with fuel?
Now make one for the 2.0 TDI. I want that blow off valve.
Very cool and interesting video, but earth is what you have in your electrical wiring at home, in car electronics Ground is used ;-)
I know this is a DIY project but I lack all the tooling and other equipment to do this by myself, but is it possible to have a set of itb's for a 2020 mx5 nd? I wouldn't mind the funds to support such endeavor.
Hi buddy, I am sure it’d be possible to put them on your car but it is so new that means the ecu will be far more interested with everything on the car. Your only choice then is to find a supplier that does one off the shelf ($$$$) or custom code your own solution with Speeduino as a base! But for the money you will spend you could buy a cheap mx5, AND the tools and learn!
@@MakingforMotorsport thank you for the advice, learning how to do it sounds like a great option, Maybe in a a couple of years it could be a great project.
Where can I buy your Tee-shirt????? Love it!
The “problem - solved” one? A present from the wife! Etsy I think!
I've been thinking about doing this to my Peugeot 206 track car.
Problem is the $2000-3000 of ECU I need
Top tip - check out my $160 standalone video! 👍
you dont need a crank position sensor?
Weeeeellll, yes and no. I have one, but if you're going from a plenum to ITBs then you'll already have a crank sensor, and as I just looking at ITBs rather than full ECUs I only looked at the sensors for ITBs...
