How to build your own custom ITB intake manifold

Lets be honest, 98% of us just want the ITB noise under our bonnets, without having to spend thousands of dollars. Today im going to show you how to make one on a low budget.

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.

Any more info? Anything you would change or do differently?

[@MattBerrymotorsport]

@@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

[@IRONGUS__]

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 🙌🏻!

[@BoostedPastime]

[@MattBerrymotorsport]

Not calculated at all, yet still works lol

[@BoostedPastime]

@@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.

This is what car videos supposed to be like!!!!

[@carl_marks1626]

That linkage is well made. Everything is well put together there.

[@lloydrmc]

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.

[@chriswhite6546]

+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.

[@MattBerrymotorsport]

Glad you liked it!

[@watahyahknow]

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

[@MattBerrymotorsport]

Yeah I've since gone to adjustable rods 😊

[@mikepowers572]

great idea, using the throttle bodies. the mesh in the stacks kills flow bad, find another way to filter it.

[@cre8tivegarage157]

Nice video , keep pushing and building we look forward to more content

[@prafdinsteleverzi]

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

[@MattBerrymotorsport]

Read top comment, I made an air box with an air filter

[@zeroswings2]

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

[@MattBerrymotorsport]

You are 100% correct. It all depends on how much time people want to spend on it. It's all done now though 😁

[@Ricerguy]

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 :)

[@MattBerrymotorsport]

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?

[@Ricerguy]

@@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.

[@MattBerrymotorsport]

@@Ricerguy 133 HP from stock 5efhe cams?

[@Ricerguy]

@@MattBerrymotorsport 5efhe cams (set to the 4e timing mark retards the valve timing 2.2degrees approximately and shifts the powerband higher up.) Yes.

[@MikediFazio]

[@matthewk9563]

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

[@charliehustle2579]

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?

[@MattBerrymotorsport]

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

[@kool-aidsphuckery9596]

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

[@Andrew-hh3ol]

I think I’m gonna work on a functional hood scoop direct to the air box , won’t be much more power but then my motor won’t be trying to have air , it’ll take when it wants

[@MattBerrymotorsport]

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

Should have flipped it, so the throttle cable is on top of the itbs not below. Like the stock 4AGE 20v have them. I have a 92 Celica st with the first gen 4AFE engine looking into a complete 4age 20v swap or adapt the 20v Silvertop ITBs over. Now with this video I'm encouraged to make custom itbs.

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??
