A properly sized, good quality filter will be a nearly invisible restriction to the system. Pipe length, tube diameter, the bell mouth on the intake and heat management all play a roll and need to be considered
@@TheCarPassionChannel This is very interesting! Maybe fewer gains, but a good start to run stock ECU? And what about safety? Will the stock ECU compensate and not run dangerously lean and hot? :D
Those are bigger gains than I was expecting for those bolt ons and an ECU! I still prefer budget spoolie-bois for cost per horsepower, but it’s awesome to see real world results with these bolt ons! Great content as always!

YOU ARE THE MAN!!!!! This is the best channel for unbiased information using basic tools. You have answered so many questions in one video. I thank you from the Czech Republic. MORE VIDEOS PLEASE,,,,,,,
Greg, thank you so much for putting in the time and effort, thats crazy :D 25whp gain op top is very good for easy bolt ons and I'm sure there is some power left with even better fuel
Your energy is amazing. Took me all winter break just to do NB2 header, radiator and all the coolant hoses. Thank you. You are basically working on my exact model. This is fascinating.
The last intake was so effective probably because of all the other free flow stuff, it's really a measure of all the parts together each adding a little to gain a bit. That said great video, love your enthusiasm for the mx5 or as you boys in the US wrongly call it the miata. .......😂😃😄
Nice work Greg. Thanks for the dedication to educating us all. Quite impressive power increase, considering it's still a stock internal, high mileage, 20 year old BP. Can't wait for the next set of tests.
How can ANYONE give this a thumbs down???? Greg, your dedication to your followers is truly amazing - you are even more of a legend (yes, even more than you already were!!)
Awesome work! You've settled up half of our pub arguments :) If you want to continue with intake testing, would be awesome to try different lengths, diameters, filters and try it with closed hood,.. HKS mushroom and RamAir are my favourites because of the internal velocity stack.
Toby put that same intake on my car when I was there as well! I think it picked up 3 hp over my J-bend, but I was already at a whopping 140 whp. Only difference to your car is the BP5 intake cam and square top. It’s still ripping years later!
that vics is sooooo cool! I have a 99 miata and i always thought it almost sounded vtec'y near redline, ITS VICS!!! didnt know i had that. very cool. GREAT VIDEO!!!
This is a great reference to what can make a difference. I'll be watching this and messing with some things with my mp62 nb1 on e85. I wish I had access to a dyno because I understand that with e85 you really should spend time doing dyno work to maximize any potential gains.
One more thing that you can try for free. Is a back to back conparisson with and without power steering belt attached. It apeared to make a fairly notiecable difference in a frend's NA vvt swapped. Thanks for the video its really good content. Awsome dedication
A well tuned, full bolt-on NB is going to be interesting to see. As Greg says, the info is out there but scattered. Maybe an intake manifold mod, and a "Car Passion Cold Air Intake" combo :D
I remember watching this when it was new and I was thinking about headers and an aftermarket intake... I chose to keep it stock --- but the difference between its baseline 96 hp and 108 based on recommendations from a bunch of his vids, going from 10* to 13* timing, a spotlessly clean throttle body, used set of cleaned and tested injectors, new plugs & wires + 91 octane on my original unmodified 290,000 mile '91 was huge, especially between 2000 and 4000 in 3rd gear where it now pulls a lot harder than the dyno horsepower might indicate. Next comes a valve job (slight hiss in intake #4 and in the tailpipe on #2) and a new clutch kit - just turned 195,000 miles on the fresh OEM replacement that was in it when I got the car 20 years ago - still holds, but the pilot shaft and TOB are getting a bit noisy...)
my miata is basically the exact same as what you have but much lower mileage, this is giving me really good incite on how much power i can expect from my car when i start doing some performance mods
That's the exact reason why I straight up removed the air filter on my car (the intake isn't facing the road, so I'm safe from stuff getting in my engine) it's been 10K miles and it still runs great (for a 1985 4 cylinder diesel)
This is the absolute best video on bolt ons ever. We don't deserve this attention to detail you provided us. Instantly subbed with notifications on great work!
Hey, could you please share your AFR and ignition advance tables? I tuned an NB2 VVT engine running a Mega Squirt 3 ECU a couple of years ago. It definitely had more power with the standalone ECU combined with similar hardware (Racing Beat header, full exhaust, and intake). However, I never had a chance to tune it on a dyno. I would like to compare the shape of your AFR and ignition curves vs the tune that I put together.
I cant remember where I saw/heard it but I want to say that anything under 10% isn't noticeable but you're looking at almost a full 21% gain so you should definitely notice it when we were tuning my car 190k 94 NA we couldn't get past the 120 mark...... Toby slapped an intake on it (dont think it was this one) and we made 127 so by freeing up that intake restriction is huge, its the main reason i wanna go from 2.5" silicone charge pipes to aluminum 3" lol
You should try re-tunnig vics to see if you can clear that dip around 3k-4k rpm and if possible putting your fuel in closed loop would make more it more consistent
Yooooooooooo can't wait to see what you do with that intake!!! My NB2 is getting pulled apart soon for some work and i want to get as much done to the car while it's down
I sent it via dm on IG but I think you should try the Mazdaspeed Motorsports Development Shim under buckets from Miata Roadster on the dyno to see what a 35% reduction of the valvetrain nets on the dyno. This content is amazing Greg. Congrats on the plaque and thanks for putting this kind of data out
The unicorn intake setup you filmed is a lot different the the emilio super miata diy intake. His had a U bend with the filter sitting in between the RF strut tower and the manifold. Yours is going back across the rad to the hot side of the car.
Greg, this is just fantastic, thank you for such a content. What do you think about throttle body spacers? There is a lot of controversion about them and not a lot of solid proofs of they're actually do something.
Very interesting video! I have the exact same car. I am surprised that the 421 to 41 headers made so little difference and that you gained so much with just the ecu tuned (fuel and timing)!

@Maverick Moshe no problem =)
Can't wait to buy an official TheCarPassionChannel intake!
Did he ever post exactly how he made that intake?
Note to self: Buy the biggest possible air filter and cut a huge hole in the hood
I think the velocity stack inside is the key.
Biggest filter possible is always a good idea. I need to get a bigger one for my intake.
Ehh I have been running without a filter on my turbo inlet for a year or 2 now. No issues
A properly sized, good quality filter will be a nearly invisible restriction to the system. Pipe length, tube diameter, the bell mouth on the intake and heat management all play a roll and need to be considered
But all the guys on facebook said these mods only lose power.
Greg: “I don’t think I brought the bathroom scale.”
Me: “Haha that’s funny”
Greg: *Pulls out bathroom scale*
the dedication is unreal, i like it
Miata dad spending quality time with us, his children! 👊
Dad!! This is the best way to start my weekend!!
Would have liked to see the result putting the stock ECU back on with those mods to see if its worse or better than stock
^^^^^
Must be the first test in the next session.
This will be done in the next dyno video.

The ECU is not a surprise, the stock set up is designed to account for a variety of fuels, driving conditions and is pretty conservative as a result.
@@foamdataservices yeah I know, I have a stand-alone in mine. Before I turbod it it made a noticeable difference. The combination of everything is what really surprised me
Budget spooly bois will work that much better with a higher power NA engine, which he alluded to with the intake runner system tuning
Greg, it’s people like you that make me proud to be a part of the Miata community. Thank you for your dedication.
It would be interesting to see a video on how much advancing a Miata's timing from 10 to 14 degrees increases power.
I think that's going to show the real value of standalone ECU.
@@alexjohn5086 you can do it by rotating the cam sensor! It's a common Miata mod. All you need is a timing light. It makes it a little snappier
i believe it just shifts the powerband to come on sooner. but then again, just info i've read before, not anything i've done or experienced
@@psrb226 You are correct, but in reverse. it gives more top end. great for racing or autocross

Just bought an nb 3 days ago. You're videos give me so much inspiration
4,2,1 header. 64mm throttle body. And a VMS crankshaft pulley. And a good exhaust.
Wow dude. THANK YOU FOR THE WORK! Many folks here won't understand the work involved with dyno tuning.
You're like the Richard Holdener for Miatas, my favourite type of video! I never would have expected that kind of power.
He really took one for the team with this one.

Miatas with cone filters just sound so amazing
And thanks now i know why my miata gets such an angry sound from 4,800 or so
let's take a moment to admire the amount of work that is involved in this video. Greg's Unmatched on youtube Miata content.
Any chance you could dispel some myths about the NB fueling, like how much the stock FPR can handle and how badly it drops pressure stock?
Just made a cup of tea, one minute into the video I am hyped. Thank you for this!

Respect! Doing that much in a single day. Looking forward to the next dyno video!
What was your tuned AFR targets at WOT. would liked to see what you have found, confirms my targets.
Dads dad jokes are just next level. He pulled out a freakin bathroom scale 😂🤣
Total respect. Such a useful piece of really hard work. Thank you
