This setup was build for a 5efe/4efe engine. The same concept can be used for any other 4 cylinder engine. Hopefully this video will give you some ideas and also help me develop them even further.

Dude you are a general ✊⚑⚑
Any more info?
Anything you would change or do differently?
@@dunkthebombI ended up making a set of adjustable linkages instead of the flat bar you see in this video... also switched from tps mode tuning to MAP sensor by using a vacuum line on each runner going to a balancer box from ebay ($30)
Made tuning a lot easier
Hey Matt, this is awesome! I am currently working on a ITB(from a BMW V8) setup for my C4 Corvette. I was kind of “stuck”, thinking only about one setup option. After watching what you did it opened my mind. I will follow exactly what you did(because you showed us it works!!). It is Saturday, 11pm, I am super happy that I found your video, it made my day! Thanks 🙌🏻!
This is exactly what engineering is all about.
Not calculated at all, yet still works lol
@@MattBerrymotorsport It isn't stupid if it works. It pains me to see people put down good ideas because they are executed poorly, not everybody has a machine shop with a multi axis mill. If it works and is done poorly then is it really done poorly? Personally I would do it. I am planning on welding GSXR throttle bodies to a Honda intake so yeah. Love the video.
@@BoostedPastime is that... possible? Wtf? How'd it go?
@@MattBerrymotorsport I was thinking of doing one for a rb20
When i saw the thumbnail for this video , my mind just thought these were gonna be bike throttle bodies.. then i started watching the video & i was blown away, never in my mind would i have considered using 4 standard throttle bodies together .... this is brillant! Well done
3 years later and you're still helping people 👍
We love it
This is what car videos supposed to be like!!!!
This is genius, love the enginuity.
I see what you did there
I dont mean to be so off topic but does anyone know a method to log back into an Instagram account..?
I somehow lost the password. I appreciate any assistance you can offer me.
@Simon Issac instablaster ;)
@Denver Alan Thanks for your reply. I found the site through google and Im in the hacking process atm.
I see it takes a while so I will get back to you later with my results.
@Denver Alan It did the trick and I actually got access to my account again. I'm so happy!
Thanks so much, you really help me out :D
That linkage is well made. Everything is well put together there.
You sir are a genius I was about to spend like 400 bucks on ebay to get an adapter plate made but to find that I can do this instead is amazing I have a 94 Corolla with a 4afe and ever since I got this car I wanted itbs. And to think this is all I had to do thank you
Legend. Good luck!
Well done! That is a truly elegant design and execution.
A suggested refinement would be to make the relative position of each throttle pin in relation to the actuator bar, so you could balance them precisely.
+1 for this. Being able to sync the itbs together is critical to a good tune. Multiple ways you can do it, but the logical way would be to fab the linkage out of all thread and use nuts fore and aft of each butterfly pickup to control sync.
Awesome job mate!I've got a set of 4age itbs that I'm trying to adapt to a honda k24.
This is exactly what I needed.
Thanks
Dam Matt , when I go down to the wreckers the first thing gone on them is the throttle body !!! Makes sense to me now hehe haha lol 😂 😜👍🇦🇺
Definitely bookmarking this one!
I was just to about to spend a lot of money for a set for my celica . This is great thanks for the video !
You are insanely talented mate! Phenomenal job 👏🏽👏🏽
Nicely done Matt!
This so amazing! Thank you for this, stay safe!
You too Edward
Cool video man. I have a Similar one showing how I make them for honda motors. Been using bike throttle bodies with good results.
Nice video! Going to try the same method on my 2e-e engine
Incredible work!
This is nice. Thanks for sharing. I'm thinking about doing the same thing for my qr25de. Only thing for future reference, headphone warnings if you're using that loud whistling music.
awesome video, makes me wanna do it myself for my e30
E30 would be cool!!
Very creative fellas. Very creative.
I think this will solve my problems with my 1zzfe to rwd good video
Amazing. This one inspired me.. Thanks bro..
Im surely will ask u if got a question 👍👍
Nicely done.
Nice work mate.
Good job guys. 😎👏👏👏
Great work bro! Very creative
Thanks man
Nice work!
I love you boss, you are awesome, it was very helpfull for me, respect you sir , pls we want more, my car is starlet ep82
Boss a great thank you, boss we want more details guide diy itb build , love you
Very impressive build!! I'm building a 4age using itbs as well
Wouldn't this basically suck dirt into your motor tho?
@@savagesock3598you put a filter over it
Thanks for this, i'll try to do the same for a Zetec engine
I've been trying to figure this out for my E90
thanks for the video awesome job
You are a very sick man!!! I Love it!!!
Thankyou mate
Want to smash the like button more than once 👍👍👍👍👍👍
I need to do this with my beams!
Not sure if you know already but there's kits available to adapt itbs from 20 valve 4age to the Beams
@@irabrook absolutely already know that, there's not that many bt 20v throttle bodies available and why would I use them on a 2L motor when they're designed for a 1.6L? I know they "work" but surely they aren't the ideal size for a beams
Cool thinking!!
Did you need to retain a lot of vacuum from the original single unit t.b? I showed this to one of my friends for some tips cause i really wanna do this on my corolla and hes talking about a vacuum block for the fuel pressure regulator.
Very cool
I thought about doing three throttle bodies on an XU1 manifold for a holden 202 ....
Nice work,,😁
Awesome project. Good work bro. Did you notice any performance difference?
Really 😎!!! Future plan thanks...
Finally a DIY to make an ITB setup for my 1uz.
Tell me how it goes
@@propaneblanco5373 I’m trying to source a sub 800.00 piggyback or aftermarket ECU since the MAF will disappear
Megasquirt
Love it!
Matt
What did you do for wiring up your itb ?
Are you on the stock ecu?
Stock injectors?
Upgraded fuel pump?
Im gonna dowload this if ever I get to a time I can build my own engine
Gotta love trumpets
nice idea. i will like to see someone try that with a honda j35 engine
cool work you should look into aluminum brazing.
Matt can you help me what can I used to replace the distributor with for a camshafts sensor segnol
On the throttle bodies how did you make that bracket to sync all 4 of them together when you pull on one of them? Was it an OEM piece you just drilled into or was it fabbed up too?
awesome!!!
Thanks for sharing
Absolutely unreal, explained so clearly and so easy to understand.
I really wanna do this to my n43b20. Its a really low mileage 2009 e92 320i. Has the looks just not the power. If i wanted to do the same, do you think i would have to buy 4x n43b20 throttle bodys or use something else. And does it have to be mapped to ecu or something? I seen the connector on the 4efe throttle body.
Hotrodding on a budget, I love it.
Will it have any issues since there are no individual vacuum hoses on the throttle bodies?
I'm building a 4age 16v with itbs and I think I may have to do this! Thank you!
Hell yeah brother i just got a 4age myself and want to get the itbs on too, the noise is awesome!
@@MattBerrymotorsport awesome! Yeah I cant wait, I'm building an aw11 up like the 80s Trd ae86 n2 cars, so trying to get the engine close to that
You should try tuning without the mesh "filtration" from what I've seen mesh in the intake stream disrupts flow and kills power, without those trumpets you have plenty of room to build a plenum which could utilize the oem ducting and filter. Just a thought :)
We tried it without the mesh, made less than 1HP difference. I think id rather lose the 1hp rather than a rock going inside lol. so was 133 hp build with a turbo or just N/A?
@@MattBerrymotorsport no turbo, I've always been n/a. I'd suggest a flow test then maybe, i think another youtuber did a dyno with and without a similar mesh and lost a fair amount of power. I was suggesting you could use an oem cold air setup and filter by building a plenum to keep the debris out and duct in cold air via the oem filter.
@@Ricerguy 133 HP from stock 5efhe cams?
@@MattBerrymotorsport 5efhe cams (set to the 4e timing mark retards the valve timing 2.2degrees approximately and shifts the powerband higher up.) Yes.
Really cool. But what I never understood about this system is what happens with all the impurities that get sucked into the intake, dust and all that. Sometimes when I change the intake filter in my car i literally find sand in there that gets sucked in
Read top comment, I made an air box with an air filter
number 1!
I'm gonna do this to my sr20 but the fuel injecter holes are on the intake manifold
i want to put itb's on my 318is e36, the problem is that i don't know what throttle bodies i should use and i really don't know what to do with the tps sensor and the flowmeter, do you know how can i find what type of throttle bodies i should use? and what do i do with the sensors?
I luv it awesome
Great build, keep up the good work ! Can i ask where did you get every single throttle body from? And what is its price?
I have a lot of spares at home. the only parts I had to buy was the trumpets/velocity stacks... they rest was just parts and things I had lying around
Oh okay, thanks for the reply !
Man what a nice setup, I've got a 96 Tercel with the stock 5efe second gen, I'd love to have an n/a build, would you recommend this engine or the n/a 4efe which I can get for cheap and swap it myself
Hey thanks Javier, they are a bit overkill for size, but still they sound fantastic and were pretty cheap to put together.
the second gen 5e don't have very thick rods... they will rev to 7000 all day every day, but if you want to run more rpm than that, go for a 1st gen 5efe with the thicker rods...
If I was to do another one, id probably do a 4efe so I can rev it a bit harder... anyway I had to start somewhere so lets see where it goes lol
Hey 👋 Panamá. Lo hiciste?
You sir are a genius! Been wrenching for twenty years and I would have never thought of that. Quick question are those the factory throttle body that's meant for/ or comes in that engine?
Hello thankyou Charlie. Yeah they are the factory throttle body x4 . That way I can use the factory TPS, plus I had a lot of spare parts to make this
I found that you can also try to use motorcycle throttle bodies. Especially if you are going to have to use an aftermarket ECU or piggyback
Ovo je materijalizacija, onoga sto sam zamislio... Svaka cast majstore! 😃
Looks good just needs a good PNP port matching job and did you say that was 7AFE engine it looks like If so that's so cool I have one of my 25th anniversary that I'm gonna try to mess around with before I go V6 walk
Hey man is there a way i can talk to you. I have a 5a-fe and finding itb vids on it are very hard i notices yours is a 4 a cld you maby give me tips and what i have to do for an itb setup on my 5a
Where can i buy these velocity stacks, i need it
Nice video , keep pushing and building we look forward to more content
What vehicle are the throttle bodies from?
very good work!🙌🏻
Do those screens do a good job in protecting the engine from sucking in debris?
great idea, using the throttle bodies. the mesh in the stacks kills flow bad, find another way to filter it.
Hey buddie, I noticed when you said you used 2 manifolds and just had them machine to the runners. One must be the manifold to the head but what about the 2nd one before you slap on the adapter plate.
Are anything related to the great allen millyard?
Perfect
What throttle valve? Of from model Car to the modifi itb
hey i just wanted to know, how would you get all the butterfly valves to open up as you put your foot down, is this done with a throttle cable or something
on throttle body number 3, i have the stock cable link still attached to the throttle. In the video i made a new cable bracket to hold it in place.
Hi Matt
very pleased in seeing some great diy guy like you. I would like to ask you some questions as it would be interesting to see if something like this is feasible for a S2000
subscribred in the meantime :)
nice idea , be cheaper then using hyabusa motorcycle trottlebodies (there larger too) or adapt some bmw ones , you still want some adjustment between the trottleplates to get the vacuum right between all the intakes , it still should work as is though
Yeah I've since gone to adjustable rods 😊
How do you balance them?
An amazing video man
Thank you for these
I thought it might be complicated or hard but never in my life thought of doing that *i know about the bike ones*
Thank you
Glad you liked it!
that's very cool and I don't want to detract from what you've done but... maybe blending out the holes between the various flanges to make a smoother transition would be better... still nice though
You are 100% correct. It all depends on how much time people want to spend on it. It's all done now though 😁
Thinking of doing this to the 2j in my is300
Man that would be awesome. Ive never seen a itb 2jz. Great idea
Genius
Giving me ideas for my k20... I wonder how hard it would be to get 4 TBW throttle bodies to work together.
K20s are electric throttles right?
Is it possible to do this to a 2009 VW Golf GTi 6?
I’d be curious to know if a standard cable and pedal will pull all of them. I suppose you could add a spring for assistance. Very cool setup and video!
I removed 2/3 springs off each TB. The pedal feels a tiny bit heavier than standard but i barely notice. Using all of the factory return springs makes the pedal quite tough
@@MattBerrymotorsport I plan on doing a similar setup to a 92’ GTI 16v this spring
@@svrider2006s how it it go?
Awesome. Any videos if it running, or pulling?
Lots on my channel :)
Starting up a Locost build with a Duratec 2.5, may take a crack on DIY ITB's Given the cost of the kits, I might give it a try with the help of 3d modeling and SendCutSend for custom plates
that’s so crackaa man not gonna lie!
crackaa?? lol
Nice video, but I got a question. I'm thinking about converting my 4afe to ITB with a 4age 20v intake manifold. Got an awesome offer on one. But I'm not sure about the air flow meter/ECU and how to get it running right.
Is it even a problem, or am I just making something up.
Hope somebody understands and can help.
Cheers
That sounds fun! Best thing would be to remove the air flow meter all together and go with a stand alone ecu. Don't waste your time trying to get good power gains from a stock ecu on a different engine.
Good luck my friend 😁
Hi Matt, I want to do the same thing in my car that you used throtter body
Hello Matt. Do you think one of these can be easily fabbed up for a 1.6L or 1.8L Miata engine? What ITBs did you use?
Can easily be fabbed to anything if you have the tools
Great concept! Well atleast if the fuel injectors are directly on the cylinder head like on the 5EFE. This will not work for example on a 4AFE were the injectors fit on the intake manifold. Any thoughts??
Buy the weld on injector bungs and put the rail wherever you like
How does the idle work?
How do you balance them?
EDIT: Running on tps or map?
I was firstly running these on TPS only so I didn't need to balance them. I have since hooked up a balancer box by drilling each runner and putting a pipe in there to fit a vacuum hose to, then hook all four up to a box so that I can run map now
What car are the throttles you used?
Awesome Matt thanks for sharing your knowledge mate !!! I’m a Toyota nut 🥜 so loved the video 😜👍🇦🇺
haha cheers!
