Great timing and inspiration guys! I pulled my FFS supercharged engine over a year ago and kinda hit a wall. Since then I’ve picked up a VVT motor and gear box and have been piling up parts… but haven’t really taken the leap . Plan is NA and eventually ITB. I had and sold a set of Jenvey’s for the old motor, drove the buyers car after the install but wasn’t impressed. Stock NA 1.8 motor though… that’s what corrupted me to the boost side… but I’m back because that isn’t what the miata excels at in my experience and that includes multiple other boosted Miata’s I’ve dealt with along the way. Looking forward to the results!
@@AGregariousPOS Really depends on what you are after. The powercards leave A LOT to be desired. Full throttle is okay but part throttle and tip in are terrible. Intake temps are very high, 220F + at full boost even with water/meth. You give up a good bit of power and mainly torque by having such high intake temps. The "ecool" is just an extra injector to fill in the lack of fuel that the stock injectors can't provide, the theory they project but have no evidence to back up, is that the fuel vaporizes... like a carb... and that cools down the intake charge. Best case, you get 30 degree drop, but in reality, as tested by FM, you get nothing because typically the fuel is injected before the supercharger. The distribution of said extra fuel is also questionable at higher boost levels, cylinder 4 has been known to pop on quite a few engines (also coolant reroute related). The actual blower mounting, belt, tensioner system is excellent however. It does work, it does make power, but you are pumping a lot of heat and a lot boost to make it. A properly intercooled hotside m45 with an ecu will make more and a hotside mp62 will make substantially more. Just for reference I've owned and helped tune a few UBER charger cars from FM with the big whipple blowers, that is a proper cold side setup. If you do supercharge the car, I honestly would recommend a Rotrex or an intercooled option if you value your engine, cats and TPS's. The FFS isn't a bad setup, it is just very limited and you have to be okay with that.
I know this doesn't really apply to adding ITBs to a 2.0 MZR but I'm just sucking up all the info I can on doing my Mazda 6. Love the videos and I know I'm a little late to the party lol.
Great to hear you’re doing an ITB build, looking forward to it. It does feel a bit like 95% of the internet’s Miatas are turbocharged, and while there are obviously good reasons for that, there’s definitely more room for a few all-motor builds!
You also forgot LS and K series swaps. ITBs are fun as shit to play with, a tad tricky to tune, but literally like the same as compared to turbo tuning. But with ITBs, you need to be more precise than with non consensual induction set ups.
I am so hyped for this build. I'm thinking about doing exactly the same thing to my car and I'm wondering whether it will just be better off doing an NA K-swap. I will be watching super closely!
I feel like I’m at the same crossroads as you with my turbo Miata. I’m curious what the outcome will be and how it will compare to a K24Z3 swap done as cheap as possible.
After comparing notes with Stefan's NA build I believe the overall cost is a bit less for the BP but also will make a bit less power and a lot less torque. However, we expect the BP to be a bit more fun because high strung engines always feel a bit more exciting. Time will tell.
Thanks for another great video!!! I look forward to seeing it!!! I have a built 2.0 by McCully Racing and I'm on the fence about ITB's but the money involved to get right is scaring me. So 1st I'm planing a moded throttle body on a square top. Best Always,
Their is a reason why Mazda dumped the “speed”. The *essence of the Miata is naturally aspirated. Revving it out. Smooth is the fastest way on a tight track never horse power.
No Gennie Cream Ale? Glad I was a piece in your puzzle (although all the parts are still strategically in shelf mode)! I may have to reach out to BOFI...
Definitely will be following this series! I just finished a Jenvey ITB install on our '91 1.6L, super interested to see how you guys sort out vacuum, idle air control, and tuning. Good stuff!
I'm very excited for this! Like you said the amount of people going all in on an all motor BP build is tiny. I'm sure a build series like this will be a valuable resource for anyone else crazy enough to build something similar
Will be paying attention to your build. Have you considered the Maruha Motorsports 87mm crankshaft from Bofi Racing? My plan is to use the 87mm crankshaft with 85mm pistons (equals 1976cc), exhintake cam, 1+mm valves, a bit of P&P and ME221 ECU. Almost forgot, the Hummelink-modifcation ITB kit.
We have considered that crankshaft but it came out a bit late for us to add to the engine. I might build another back up bottom end and include that crank.
I'm looking into the Hummelink ITB kit myself. I had the original Jenvey kit from Rev9 which was just a pile of parts that didn't line up or work at all.
Since those what look like Jenvey ITBs, there is a good amount of DIY on them, but it's worth it. I run them on my NB1. If you need advice for balancing and what not, please let me know, I will be glad to help as much as I can.
Really looking forward to this, I am currently ITB but mine is a mild build in comparison (some head work, stock cams sadly) so seeing what a full 100% build is capable of will really be exciting. I’ve been on the fence about taking the build further so this will be informative.

Thanks! A bit of work seems to go a long way in waking up the experience. Add a six speed and I think you’ll be very pleased.
How did you like the FFS kit? Have had my eye on it for a while.

@@NappMotorsports certainly I now want to keep my VVT for better driving ability

"So delicatly fluffy" Nitro Pepsi - GET SOME. ROFL - this was funny.
😂
That’s exactly what I want to do to mine. 2.0 ITB. Mine is not VVT tho!!
VVT IS THE WAY!
Yeah this is gonna be sick. Always wanted to do ITB's but kinda seemed like a pain. Interested to see what all goes into this.
Thanks Alex, should be a good time.
All I got was something about boys massaging their head and some "so delicately fluffy" liquid.
Hahahaha. It’s a miata owner thing.
Itb?! Tight
I am so hyped for this build. I'm thinking about doing exactly the same thing to my car and I'm wondering whether it will just be better off doing an NA K-swap. I will be watching super closely!
Just forecasting, the cost will be almost the same.
Welcome to the club!!!
Thanks!!!
I legit was having this Convo with myself the other day.....itb or turbo.
Fucking go for it!!!!! Can't wait to see it.

Very exciting and great timing. I’m toiling between turbo or ITBs at the moment, so this will be an informative series. Best of luck with the build!
Thanks. Feel free to reach out with questions via Instagram.
Okay, just ran into this...I'm subscribing & don't even know where y'all are in the build! (Lifelong gearhead, grew up on small block MoPars)
🤙🏼
FINALLY, NA MASTER RACE
NA ALL DAY!
Really looking forward to this unique ITB + built motor build. Should be a ripper! So awesome that you build but also track your cars.
Thanks, thats the plan. Hope to do a shake down at the track next weekend.

I’d agree but most of the internet I think wouldn’t but no worries. Took me trying the turbo to realize it wasn’t for me.
No Gennie Cream Ale? Glad I was a piece in your puzzle (although all the parts are still strategically in shelf mode)! I may have to reach out to BOFI...
It was awesome being able to hand off the setup to you. BOFI is awesome, good parts and great people.
So many goals
Thanks! One step at a time.
@@NappMotorsports first step is to manual swap the automatic out of my 90 miata
Definitely will be following this series! I just finished a Jenvey ITB install on our '91 1.6L, super interested to see how you guys sort out vacuum, idle air control, and tuning. Good stuff!
Great! There are a couple of options, we will be sure to highlight this in the series.
I'm very excited for this! Like you said the amount of people going all in on an all motor BP build is tiny. I'm sure a build series like this will be a valuable resource for anyone else crazy enough to build something similar

The 180 HP motor would be a great car just to drive an have fun!
Couldn't agree more.
I’ve never needed to see the next episode of a miata series ever before
Baaaaa. Thanks for the high praise. More to come soon!
Is the engine coming from chikara?
Nope! Custom engine rebuild by us. More details to come in next episode.
Yes! Eager to see all your hard work on this.
Thanks! Can’t wait!
Following for sure - everything y’all do is top notch, this is such a sick idea
Thanks man! Lots to come!
I am really glad that you finally got some serious sponsor! I hope you can achieve your goals in a short period of time.
BOFI is really a partner with the project. We wouldn't be here without Dan's help.
Since those what look like Jenvey ITBs, there is a good amount of DIY on them, but it's worth it. I run them on my NB1. If you need advice for balancing and what not, please let me know, I will be glad to help as much as I can.
Appreciate the support Travis! I believe I just found you on instagram. Will reach out if we have any questions.
@@NappMotorsports Deal! Surprised that I was easy to find on IG.

How do you like your current setup?
NICE! gonna be great!
Awesome!
0:52 1.6 gang🦍🦍🦍💪💪💪
Just got to 1:22 it was operator error. No way that engine failed
Hahaha. That long nose crank is a known fail point.
@@NappMotorsports short nose cranks ftw :)
At last!
Late but still going to deliver!
