This Mazda Miata is a Loud, Unpredictable RX-7 Impersonator | NA meets FC

[@NinerRacingDivision]

What I love about this build is how this MX5 basically got turned into an FC without hindering the original spirit of the Miata being a fun, direct, and communicative drivers’ car. Such an awesome build

10/10 build for me! Theres something about a small NA motor to me, the "less is more" theory! The ONLY thing he needs to complete the build are 2 holes in the hood to get in some FRESH air, that rotary engine bay runs HOT. And have 2 "snorkels" built in to the under side of the hood that have a rubber seal around the top of the carbs. He wont gain much hp, but you will RETAIN as much hp as you have longer by the cooler air. On a hot day that carb setup can lose 10-20hp from hot air intake temps.

[@Beansswtf]

Mx5's have actually been proven to have hotter engine bay/intake temps by having holes in the hood haha, same thing happens when people remove the factory plastic undertray also. Obviously not a factory engine, but in theory the science should stay true

[@ralkia]

@@Beansswtf Not to be that guy but... source? It could depend on where the cutouts are made since they may affect airflow, but the engine bay isn't going to spontaneously get any warmer when you vent it more lol.

[@tubejorrit]

@@ralkia Guy Bean is right, it all has to do with airflow and creating a vacuum so hot air gets sucked out of the engine bay. Just cutting holes could lead to a hotter engine bay.

That 13b suits the miata so well. Its light weight, high revving and powerfull it doesnt get any more fun than that.

[@itbmiata]

this exact project has been in my mind for so longgg, great to see someone else sees the potential of a fun low torque, high revving engine in a small light car similar to the rx7

[@ericnazario2369]

I didn't think I'd ever want to build a miata. Then this comes into my feed.

[@jaimegrant784]

What has he done to the engine? I see it has a Weber 48 IDA. This tends to hint at at least a street port. That will give you at least 180HP compared to the stock Miata 116HP. It definitely isn't bridge ported though. That would put it more in the 250-275 HP bracket. I nearly put a 300 HP peripheral port 13B into my na Miata years ago. Having a daughter on the way put an end to those plans though. Now that the kids are grown, I'm currently putting a race ported 12A into a highly modified Triumph Spitfire. Should be loads of fun

[@Mantenner]

Those power figures seem insane, is that really true? With the differences being strictly porting? I had a mate with a bride port renesis and he barely put down 150hp at the wheels, I know they're a bit gimped compared to a regular 13b but surely not 100hp different with the same ports.

[@jaimegrant784]

@@Mantenner the power figures I gave are at the crank. The figure you gave for your buddies renesis seems very low. A stock Rx8 made more than that. He may have had some issues with that motor. With each port, the power band changes too. You must rev it higher to get the power. My peripheral port 13b idled at 2500 rpm. And that was a rough idle. It smoothed out at 4000 rpm. But at 7000 rpm, it was like you got shot out of a canon. And it just got better up to 10, 000. A bridge port likes it up there too. Perhaps they didn't take it high enough on the dyno. He would need to take it to at least 9000rpm to see peak horse power.

[@chrishuyler3580]

@@Mantenner A good running renesis should put 185+ hp at the wheels. This FC 13b with just intake/header/exhaust is probably around 160-170hp at 7,000 RPM with the ports holding it back from making higher RPM power. And yes, an N/A 13b can make 300 crank hp (250+ to the wheels) with the right porting and supporting mods.

[@RoadsUntraveled]

Yeah it's been awhile since I've driven a stock NA. My power assessment was strictly butt dyno talking haha, my mistake. I doubt it makes anything close to 180HP. I was driving an ND MX-5 again last week and it was MUCH quicker than this NA. Like a lot.

[@iraqifoodcart8447]

2:30 "you have less power here than a stock NA 1.6" that is factually not true. I used to own a 1991 FC convertible, which was NA. That car made around 160hp when it was new, whilst the NA Miata only made around 110-130hp.

[@bigzoinks93]

Yeah i’m trying to see where he got that info.

[@RoadsUntraveled]

Yeah it's been awhile since I've driven a stock NA. My power assessment was strictly butt dyno talking haha. It should make slightly more power, yes. What I should've said was that it **felt** like it had less power than a factory Miata. Dumb mistake! Both very underpowered, but I'd take the rotary over the 1.6 or 1.8 any day.

[@FUCK_________googIe]

Yeah with downdrafts and a good exhaust that car makes 200 at the wheel. This channel is cringe

[@Ben-Rogue]

Mazda should have sold the MX-5 with the option of a rotary, and the RX-7 with an optional forced induction version of their K-series V6

[@jo-qp7mz]

I've been saying that for a while! They should offer the new Miata with the option for rotary!

[@pgtmr2713]

Yes and yes. RX-5 and MX-7/8/9. All they really needed to do was get rid of the junk distributors and go coil on plug for the KL. My KLZE is currently down, suspecting the distributor... once again. Still a fantastic engine for small light cars.

[@265justy]

Yeah it's a shame they never offered the K series V6 in a RWD platform. MX-3, Lantis /323F and MX-6 were still nice cars tough.. Only they were Fwd.. Mazda made beautiful Coupes in the 90s from the MX-3 up to the FD RX7..The 323F was never offered in North America. It was a timeless 5 door coupe design in the 90s.

[@tabdougherty8549]

I owned a RX7 and I always thought why did they not put this in a Miata it is a perfect match. If all you have driven is piston cars, The rotary takes a while to make sense. They are far happier at 8k then 2k and weigh half as much as a 2 liter. I wish I never let my RX7 go.

[@JNAMOTORSPORTS]

I said the next Gen Miata should be a rotary since the RX car isn’t around the ND Miata is begging for a rotary

[@darwonboyful]

Surely a stock 13b makes more power than the 1.6l 4 cyl from the na mx5? A stock carby fed 13b makes about 130hp and a stock 1.6 na motor only makes about 113hp. This 13b has a weber and headers etc so its got to be making about 150hp

[@chrishuyler3580]

Intake/header/exhaust on a bone stock FC 13b is gonna put down 160-170 hp to the wheels. The 1.6L is around 100hp to the wheels. This is a massive power boost if done right and it doesn't add much weight either.

Great video!

It looks like a blast to drive and that's all that matters as you can have big HP numbers but totally ruin a cars driveability. It was nice to see Chilliwack represented, as you were filming right in my neighbourhood where I go running, and I also use that same route to test out my project cars on! If I can get my act together( I blew the axle out of it last weekend) maybe you'd like to test out my 1972 Porsche 914 it's got a 300+HP 1.8t big turbo (for its time that I started putting it together early 2000's) Boxster transmission and is mostly fiberglass so it only weighs 2080 pounds with half a tank of gas. I need to put a new clutch in it as it started to slip and won't hold past 5000 rpm now, and now they sent me the wrong size axle as I'm having to upgrade to Porsche 930 CV's.

I don't think it's possible to get a rotary with an aftermarket carb to be as weak and gutless as the 1.6 that makes exactly 99.98WHP, so no idea where that statement is coming from. I can see maybe 120-135whp with this setup seeing as it's an S4 NA with a weber on it, but not sub-99.98WHP (If anything it's making that for torque at the wheels). If it really was that weak the engine would be barely running and likely dying every time you stopped.
