Satisfying because it’s the sound of the motor about to fire up within a few turns whether it’s stock or highly modified. It doesn’t matter, because all Miatas start the same.
I want to go with ITBs on my NB so badly, there is something so special to me about a reliable naturally aspirated clean engine bay that sounds amazing. Im just worried I might regret not going turbo for more power later on down the line...
Forget forced induction, any monkey can do that. And don’t lament not having the most power. A naturally aspirated motor like this is special, and more in keeping with the spirit of the Miata, and all the little sports cars that came before it.
I see this is old but it seems the only way would be to make a MAP 'plenum' where you take vacuum from the engine side of the throttle bodies and combine them to a single small tube fitting stack, so you have 4 vacuum lines in and 1 line out to the MAP sensor.
I'm guessing that megasquirt is also getting the RPM as input using a crank position sensor? how would it otherwise be able to calculate the Mass air flow...
Questions. What kind of breath filter is that I heard it's actually not healthy for the engine? After you got this ITB conversion, what kind of tuning did you do? DId you take out the engine or could install it like that? Looks amazing!!
That is a smooth idle on an ITB setup!
I was thinking the same thing! Smoother than my stock idle.
Why is the starter of a miata so satisfying to hear
I wish my Miata starter sounded like that. I have a later NA8C with a different starter sound
@@acerusea5156 Aren't starters compatible?
It's satisfying almost every time it doesn't make the alternator pulley scream at you

Because Mazda 😍❤️
Beautiful man, just beautiful!

imo the Miata isn’t abt all power, what makes the Miata fast is the driver. If you can gap the higher hp cars on the track that’s mad impressive.
@@calvin9940 I really do like the idea of ITBs... strongly considering it on my NB

I can’t find ITBs anywhere for my Miata
Nice setup!
Do you have more info / videos on this build? I'd love to know more about the motor
That thing revs quick for a Miata
Jack do a full review and video of this
good ol skeletor
Thats nice only through map
Does this use stock injectors with a mega squirt, and what changes to the throttle cable?
veddy nice
Are the 4 vacuum ports linked to a vacuum tank ?
Same question
Go get some gas man. ⛽️
Should have talked chris into doing itbs😂
Im running the same OBX itbs!!! But im using dual maps. One for Speed density and another for aTps fueling. What other mods you have?
SuperWepawepa m
SuperWepawepa how do you like the obx itbs
Do you have the seats mounted to the floor
How could you get it to work with map sensor only? Please help :( haha
where or how do you actually place the map sensor in an itb setup? i'd love to learn more about it!!
+1 would love to see the plumbing on this. Hopefully @jack cecil can show. TIA!

@@akkudakkupl agree with this as well. just curious on how he did the plumbing for this and his "plenum" size/fitment.
@@akkudakkupl would love to see the build notes on this
How did you connect to the map sensor?
Which flywheel is it running? The revs are definitely a little faster than mine which is turbo with stock flywheel
turbo is gonna take longer to rev anyway, itb revs quicker cause the air has less distance to travel, he very well could have a flywheel as well idk
I'm guessing that megasquirt is also getting the RPM as input using a crank position sensor? how would it otherwise be able to calculate the Mass air flow...
uhhhh....yeah. It has to know when to fire injectors....
0-60: yes
So with ITB do you need a air filter. How does debris not go into the engine?
you should use filters on them there’s nothing stopping debris from entering
Needs a lightened flywheel
Can it run properly with stock ecu?? Sorry for my english
No vacuum line connected to the fuel pressure regulator? Cause I am about to setup mine.
Not needed.
Is it run off a vacuum balance bar to the map?
Where did you put the MAP sensor?
you dont need it with an aftermarket ecu
I was just gonna ask which Map are you using off what, video says running on map only?
you usually have 4 pipes tapped in after the butterfult valves all going to a map sensor
Questions.
What kind of breath filter is that
I heard it's actually not healthy for the engine?
After you got this ITB conversion, what kind of tuning did you do?
DId you take out the engine or could install it like that?
Looks amazing!!
They’re trumpets. The problem with them is that they lack filtration.
Wow, how did you make the the map signal smooth? I see you fuel pressure regulator is not connected?
In line restrictors
@@Pooooooops thank you. I will try the same, with extra vacuum manifold. I hope I will get it running as smooth as this.
How many powers?
Why not run a TPS ?
What throttle bodies ?
look like jenvey
What happened to the oil gauge as you revved the car, dont look right.
Lukewilson57 how so?
Thats oil pressure, which climbs when the engine is revved
Samuel Ashton that's what oil pressure does when you rev an engine.
Yes, I know.
The NB miatas have a dummy oil pressure gauge that doesn't move like that it stays in one place because of the sender unit
Can you run a itb on a daily driver miata with a stock engine bay
just curious
Mother_Herd you can run ITB’s on a stock engine, you’ll need a aftermarket ECU though
I can reprogram my ecu to deleted the flowmeter?
1.6 or 1.8?
Looks like a 1.8 based on the valve cover
MAP vs TPS, why choose one over the other?
how much HP is this making?
Cramer Ward-Collings 145whp
Jack Cecil id love to race my miata with urs lol mines got a slightly built motor.
With some cams, upgraded valves, upgraded fueling, p&p, and shaved head should be able to achieve 180+ whp n/a at nearly 8000 rpm, stock bottom end
Could I do this to a stock miata
They’re all stock in the beginning.
@@JackCecil ok
Oil temp goes up and down as fast as the revs! 😂
That would be the oil pressure gauge
@@Alysavos-rd4tp oh lol.... thanks
That’s oil pressure, not temperature.
If yes how?
