J-Series V6 Miata Overview

This is a video overview of our J-Series V6 Swapped NA Miata.

[@id744]

Absolutely the cleanest J swap Miata! This is what the complete kit should be. WOW!

[@gorillaKBC]

That intake manifold is fire I would like one like that. Totally matches the valve covers

[@VictorPitstop]

I’d wager you would do well selling those manifolds and get more peeps on board with the swap. Very clean setup! I’ve always loved the idea of the J series swap, but always thought the fab work was half-assed on the examples I’ve seen. Good power, cheap but not always easy.

[@pqjade]

Agree 100% on selling the manifold.

[@accordingtoabe2211]

I'd buy this manifold right now if it were available

[@mazdamiata2293]

Would like to purchase *1 Intake manifold *Miata power steering pump mounting brackets for my future swap. I have a J32A in the corner waiting. You're welcome to sign the intake manifold. Not kidding. Great work!

[@JrVtec]

That intake manifold is awesome man! Very clean build.

[@pqjade]

This is the cleanest swap I seen on a Jmiata , very nice. First question! How much for that intake manifold? Please make a couple and sell.

[@chrisg6474]

I second this.. got a j30 I’m trying to throw in

[@jasperduncan5846]

I third this, it would be very much appreciated:)

[@humbletrends2937]

Hey man thats your niche , you should definitely sell that manifold as your product. I agree with them, its very clean!

[@sirlyndon124]

Also keen

[@shawnlynch9826]

We're waiting for these things to be posted

[@davidmccaughan2710]

Patrick, awesome video, thanks for posting. I'm getting obsessed with this swap for my '95, I too don't want a race car and ultimate performance would not be the goal. Between you and Jason I think you guys have solved the major hurtles, both cars have some great solutions. Not having the machining experience or shop availability, clearing the hood is the last issue keeping me from pulling the trigger. Great car, enjoy!

[@pineconearmy7561]

Patrick this is an awesome video well done bucko great seeing you pave your way through the world kiddo.

absolutely love that intake

[@CameronsCars]

Can’t wait to see more driving videos. You earned a subscriber! I’d love to see a custom intake hose made!

[@PapiDoesIt]

That is a crazy clean swap! You definitely need to sell those intakes.

[@beatdaoddsremainhumble1724]

Nice job on the manifold 🤘

[@noahalcoser1977]

Thinking of getting a Miata and doing this swap. You remind me of someone from 2008 lol

[@djroland1]

I watch this video over and over and as I get closer to starting my swap, I watch this every day. Tons of detailed info and inspiration. Thanx for this vid. Any chance you'd recall what hoses you used for the coolant to the heater core?

[@patrick.woolfenden]

Sorry, I don't recall exactly. I think it was a combination of the stock Miata heater core hoses as well as a hose from my local O'Rielly auto parts. I asked if they could take me to the back of the store where all their molded coolant hoses are hanging up to choose the one that looks like it would work. I think I ended up with a pretty long hose with a bunch of bends that I cut a section out of.

[@idriwzrd]

Love that trunk rack. And the FD.

[@RobWhittlestone]

Patrick: super clean setup! I'd love to have a V6 swap for my 2009 NC Sport. It's a refined car and a refined engine would make it awesome. Engine is a Honda J32-2-series V6 right? 3.2 liter displacement. Over 260HP?! Beautiful engineering solution. 28:19 sure has enough torque for a light car! Excellent work! All the best, Rob

[@DaRealChrispy]

This video is going to be the bible for my swap

[@mazpr2025]

Noticed only one video, any possibility of showing or explaining more on gearbox, reliability, tuning/engine management? Is there a link to a forum with more info?

[@MichaelBLevi]

You've done a terrific job here guy. Well done and thanks for sharing.

[@Morboeatspeople]

Great video! I'm supposed to meet up with one of these from CT.

[@JohnDoe-je3cr]

just found this, beautiful car!

[@roldannunez9866]

Great Job 👋

[@dominicandawg3455]

Dude great job on that intake! I have a j35 I’m pulling from my odyssey and going to build up

[@LenbIix]

cmon patrick more videos brother this swap is sick

[@EdA-bz3bu]

Like a lot of detail. Like little long winded. Like excellent job, keep it up. Like 👍👍

[@nickespo89]

The manifold is awesome.

[@mr.adventure559]

It's quick, a lot engineering though to get it working right.

[@craiglawson6103]

Nice intake for sure.

[@mulonru2965]

Really loved your video

[@wils_builds]

Dude this thing is awesome!

[@PedalMafiaM]

I would also like to buy that intake manifold!! you should really sell these ;]

[@thejimmyd]

Patrick, I am planning a similar build myself. Can you contact me and talk to me about the manifold you have built. I would possibly be willing to either buy the plans for it, or if you wanted to make another one, Possibly just purchase it straight from you if you like. the car looks clean and Congrats on making it happen

[@davidlowe3793]

You should make some more manifolds and sale them !! Bc I would buy one

[@jv6miata]

Hey man, do you have some practical daily type info you could share? NVH, how does it handle highway speeds at over 3.5k rpm and the gas mileage. Also do you have a J32A2 or J35A5

[@benjaminvaughan4481]

Hey man, love the build and the attention to detail involved with it! I have a question about how you flipped the throttle cable mechanism on the throttle to get it to open the other way? This is my last step to getting my j32 rx8 driving down the road

[@qrs3658]

Very good swap. I applaud your effort and dedication for doing such a swap. Niceeee. Put a TorqAmp Supercharger on it now

[@projectmiata]

Very nice !

[@peterbonnez]

Excellent

[@muzixman2011]

how do you feel driving under this noise for 30 mins? how much heavier is this engine over the original one? is the 2.0 Skyactive engine of the ND more practical for this car?

[@mulonru2965]

I wonder if the rear end had a 308 gear ratio with v6 if fuel economy could be in 40mpg range

[@alejandrogomezdominguez6299]

Do you sell the customize manifold?

[@camerond8894]

Amazing bro

[@craiglawson6103]

Would like to see this at Import Alliance 🧐

[@davidlowe3793]

What is that intake manifold? I love it

[@Boxplotmusic]

commenting just in case the intake manifold goes on sale

[@shadow-fq7nk]

Hello Patrick! I wanna ask you about the swapping of the engine mounting kit.. what did you come up with. Let’s say I have Honda prelude I wanna do the same swap. Is there a source for that? One more thing, what transmission do you run? Thank you that’s a very clean swap... Sweet! I love it!!

[@patrick.woolfenden]

I am running the stock Miata 5-speed transmission. For the engine swap I used the MiniTec JV6 Miata package. This came with a new front subframe, engine mounts, and adaptor plate to attach the Honda V6 to the Miata transmission as well as other parts. www.superfastminis.com/store/p_982283/jv6-miata-package J-swapping a prelude is not something I know about. There could very well be kits to do it. It's just something I have never researched.

[@DidierBan]

Hey , awesome job done Patrick , does this swap uses a adapter plate for the transmission?

[@patrick.woolfenden]

Yes, it uses the adaptor plate for the Miata transmission that is included with the Minitec kit.

[@abc_builds]

What kid did you use?? Does it clear the hood and also do you get to retain the AC?

[@patrick.woolfenden]

It's the Minitec kit. I think they make an AC compressor mounting bracket if you want to keep AC. I made my own intake manifold, but they also sell one. With the Minitec manifold I think a bit of the rib structure inside of the hood needs to be cut out to clear.

[@cookie327]

Amazing build man. J32a2 or a3?

[@patrick.woolfenden]

It's a JDM J32a equivalent to a USDM J32a2

[@cookie327]

@@patrick.woolfenden Overall, would you say this swap is worth it? Level of complexity? I know you did a custom build with many custom parts, but what would you say your overall spend was? My plan was to go with a megasquirt PNP3, so similar custom ECU workload and cost.

[@patrick.woolfenden]

@@cookie327 My total spend (not including purchase price of the car) was probably somewhere between 6-8K. It was worth it for me. I like how the car turned out and it was a fun project. You will get more power for the money by tubroing the stock engine. It would also be less work. But the J-Series Miata is a pretty cool thing and is a totally different feel. Lots of instant low end torque. The most complex part was the wiring. I referenced wiring diagrams and combined a J32 wiring harness with the NA Miata's harness. The AEM Series II AEM30-6051 is kind of old at this point, but it is plug and play for the older J-series engines. With the Megasquirt you will need to configure everything for the engine and setup an additional relay or something to actuate the V-Tec solenoid. V-Tec requires switched 12V. Typically ECUs switch outputs to ground not 12V.

[@Oldieeeee]

Okay cool build and all... But seriously how hard is it to change the timing belt? It looks like a tight area lol

[@patrick.woolfenden]

I honestly think it would be a lot easier than a car with a transversely mounted J-Series. The radiator can be removed with just a couple bolts, an electrical plug, and a couple hose clamps. Then you have tons of room and easy access to the crank pulley bolt.

[@Oldieeeee]

@@patrick.woolfenden when you put that way, you're right lol

[@jasperduncan5846]

How much to get one of those intake manifolds bro?

[@eric1138]

Great job! BTW, I'm hearing numerous rising intonations. Keep in mind in your presentations that you are giving information not asking questions.

[@Backupnow-gf7wb]

Where is the intake for sale at ?????

[@pixeldennis2862]

that coolant hose?!?!? where what is it? custom or you find something that fit just right? couldnt agree more about the ugly intake setup .... can you do this and keep ac too? we really need to come together and get that LS intake with block off cheaper.... or convince minitec to design a better intakemanifold. ive talked to him directly he said they have tried a lot of things.. they just cant seem to get the right combo. you can see one of their intake designs on their site with photos...

[@patrick.woolfenden]

The upper radiator hose is from a I.L. Motorsports Miata coolant reroute. Its available separately.

[@adamramirez8335]

Hey buddy where did you score your engine? I am seeing a bunch of options online just don't want to get something busted.

[@patrick.woolfenden]

I got it from my local JDM engine importer. I think it was only $500.

[@abc_builds]

What intake manifold is that?

[@patrick.woolfenden]

It's a custom billet aluminum manifold that I machined.

[@charliehustle2579]

How much to do this swap? As in the complete cost

[@loganhunt2528]

I've heard from 5k to 9k

[@icebergtactical1096]

Depends on how much you can do yourself vs a shop doing everything. As well as things such as higher or lower end parts, if you have a j series on hand or need to buy one, etc. But I've done the math for myself and I'll post my own research below. If you want the TLDR, 9k N/A and 15k supercharged. Both figures are parts and associated shipping only. Engine: 1k average ebay motors Subframe to mount engine: 3500 Tranny rebuild (required for horsepower gains): 1300 Coilovers : 1k Bigger tires and wheels : 1k Big brakes: 900 Here is where mine varies, I want to supercharge it eventually. You still need a better radiator but could go much cheaper here. Custom intercooler (to handle much much more heat, and cool oils) 800 Supercharger: 400 Supercharger adapter: 600 Aftermarket cf hood to fit package and handle heat: 800 Heat shielding: 200 Aftermarket ECU: 750 Upgraded fuel system: 1700 Additional parts not listed: sensor upgrades, brackets, relocating accessories, exhaust work, etc: 1k Bottom line non boosted: 9k ish parts only. Boosted 15k

[@johntheawsomeful]

Will you be my friend?

[@volatile2805]

I never understood the obsession with JDM engines. They are almost always abused on the oil changes and have so much carbon coke in the engines. Its always been scary looking inside when I open them up. I can understand if its something we dont have in the US but if there is a US variant, there really isnt a benefit to buying a carbon coked JDM motor just for some kinda "Clout". Regardless of me not getting the JDM thing, damn that car must be fun to drive based on my exp with other J swapped vehicles I have driven.
