Clutch Upgrade to Get FAST Revs From Your Miata! (& How To Re-Seal Your Transmission)

FAQ: You must match the 1.6L Clutch with a 1.6L Flywheel, they are not cross compatible with 1.8L parts. But they do bolt on with no modifications, and it's the perfect upgrade if you love quick revs and don't need a massive load of holding power. Even the 1.6L ACT Xtreme with the 6-puck disc should be fine above 300whp though. I also get asked a lot about the difficulty of driving with a 7 pound flywheel. Yes the engine does stall slightly easier when you take off from a stop, and the revs drop very quick between gears so you need to shift a little faster in order for it to be smooth. But if you enjoy driving manual, you'll get used to it in 2 days and it will feel totally normal.

Finally after years of watching you I got a miata this weekend and can put some of this knowledge to use.

[@devonswindell9735]

I'm sorry

[@testacorsa150]

Good for you man. I watched a few carpassion videos too, before wrenching, and now I'm on the 6th year of ownership. Love that little thing! Welcome to the club :)

[@elwindewitte]

Heck yeah dude! Have fun! What generation did you get?

[@bmanjohnson51]

I’ve been watching for years and know most in and outs of Miatas… but I still watch with enthusiasm to see if there a even a smidge more of information I can learn to make my experience even better!👌🏻

[@TheGameplaya2011]

I pulled my motor last month and cleaned and did a refresh on every gasket possible. I didn’t think about doing the transmission seals at the time. I ended up putting the motor and trans back in and drove the car for 100 miles. Turns out that one of the seals was bad and was pissing tranny fluid everywhere. I ended up pulling my transmission today and changed the all the seals. Wish me luck that it doesn’t leak! Also great video! I wouldn’t have tackled any of this issues if I have came across your channel, much love Greg!

[@taylorramey9498]

For the shim you can also use a dab of grease (I use automatic transmission assembly grease)

[@swiggityswagger1232]

I love your videos man! You're the best car KZbinr out there. You've inspired me to mod the shit out of my Miata! Love you bro!

[@slartbarg]

That magnet trick is pretty slick, I've never done a transmission servicing like this but I would have probably racked my brain for hours trying to figure out how to make it easy

[@coronel2076]

It's always a good day when miata Dad posts

[@mostlyuselessgarage]

Always practical and informative content! Can't wait to see you make 200whp naturally aspirated!

[@davidrodgers2511]

Finally got my Miata, after finding your channel during Covid lockdown back in 2020! Your information is extremely useful and centralized. Not having to read miles of form post is very helpful.

[@DrifterDavid]

Keep grinding buddy! Thanks for the update video! Enjoyed it! Learned something too, I know how to do all this stuff but still found something I didn't know. No idea about that weep hole on the seal and I just swapped my trans/clutch this weekend. Just went out and popped it out and put it back in right. Thanks for that! Take care buddy!

[@AndrewTheHoff]

I don't even have a miata anymore but you gotta love craigs content, top notch and always entertaining and educational.

[@lipvandip6480]

You mean Greg right?

[@AndrewTheHoff]

@@lipvandip6480 you must not have been here long.

Thought about doing this when I had my motor out. But my build has cost a little more than expected 😅 maybe next winter. Great videos man! Keep it up!!!

[@kevinmcinnis7180]

You are the best thing to happen to the miata community man!!!!

[@0DFMR0]

Man, real cool videos you have, ty for show the people the "how to do"!!! Love your channel. Im dreaming about buy a miata, and now i really want to buy one!! Keep doing this, because you are doing right!! Im from Portugal, and as every one see my English is not good, sorry about that guys... I send a big thumbs up from Portugal. Great channel!! 👍👍👍

[@Olysk8er]

Finally, a good example of a straight shot clutch line that isn’t a vague reference in an 8 year old forum thread.

[@VerticalGamingStudio]

Love it!!! This is a great example of a driving experience mod. I miss my miata, have an 01 Mustang now (lol) Fidanza alum. flywheel, smaller 10.5" clutch with an aluminum circle track pressure plate. Very fun!

[@GiveItBeansGarage]

I’ve watched your video on how to change a clutch until I memorised it too every last second. It took me 3 days to complete but my car is working better than ever!

[@jordanward1858]

What’s up man just litterly got back in from taking out my gearbox I’m putting a 1.6 into it didn’t know if it would work now I’m happy to see this thanks so much hi from Ireland 🇮🇪

[@aaronm2452]

Another fantastic miata monday!!

[@raymonddonovan3297]

This is the best car channel ever. No joke, Miata Dad >> literally everyone else on KZbin.

[@TheCarPassionChannel]

I appreciate your kind words especially on this most basic video 😆

[@nickv22]

Just got a spare 5 speed (and fm turbo kit for my 2000 NB) I plan to reseal the trans so I am excited for this video

[@chadb.6165]

It's crazy I have a ACT clutch and lighter flywheel on the way (Wed 🤞) and you drop this :) this will be my first time doing it and not going to lie little nervous lol thanks for the video

[@TheCarPassionChannel]

Good luck man! Check out that full install video I got and it should give you a few helpful pointers!

I love the TransPassionChannel. ❤️

[@fatninja987]

I’m here dad

[@DjNoize21]

missed your video´s🤤

[@DarthKoal]

Honey wake up Craig posted!!!

[@hewbambam]

Greg, a magic trick to hold that shim in put a smear of grease on it and it will stick in place so you can put it back on.

[@candycornpeeps]

I have the same exact clutch flywheel combo. Very responsive.

[@whitebear96]

i have the exact same clutch/flywheel setup on my VVt and havent noticed any change in rev speed, when reving the engine just while standing. I did take video of reving before and after install, and the speed of rpm raise and fall is the same :) rev matching between gears seems to be better and more responsive though it seems. one con is that if you daily the car, snailing in traffic just with clutch is impossible, always need to rev it to move.

[@faststang4892]

i wish i had a friend like you to help me with my miata :(

[@zacharytribou2728]

You can stick that thin metal washer into the input cover using grease

[@bizkify]

Babe sorry i can't make it tonight papa greg posted

[@raymonddonovan3297]

Can’t wait for that bolt on only NB dyno day :)

[@paulkimble4548]

Keep it up!

[@hewbambam]

I did the seal job on mine, it didnt have a shim, or a gasket. Just straight rtv silicone is what's sealing my cover plate on.

[@3576alan]

!:58 '"And, it's 'mated up with'... "Tony Danza"'😁

[@jaredfinucane9319]

Love you❤️

[@the0844]

I recently did the same job on the transmission of my NA…replaced all the seals…and then it started leaking from the little seal inside the output for the speedometer cable >_>

[@ricks_toys]

I can feel the NB is getting ITBs.

[@hewbambam]

That looks like a 5 speed housing? It has no extra bracing on the outside.

[@craigdishmon1513]

Can you help. 04 Mazda speed 6 speed. I pulled wrong bolt out of trans to fill with gear oil. I pulled the 8mm Allen on opposite side, and now it won’t go back into gear or shift. Who can I call for help? I did pull trans back out & ordered a Small Camera to try & line this long adjustment bolt back up in right place.

[@hdhellion4128]

I might have missed it, but what's the current set up on the turbo 2.0 NB now?

[@jv6miata]

Will the Stainless line snap into the holder on the firewall?

[@samfitburr]

I am only running stock nb vvt power and my clutch is coming to an end soon. So i wonder if it would be worth it to go for a 'Xtreme Clutch 1.6' and a light 1.6 flywheel of some sort. The clutch only costs 300€ so its not that big of a price gap to a normal aftermarket one. But i also dont feel like throwing out money for no really noticabily difference

[@seayata]

Still not giving up hope there will be a NC on the channel one day 🥺

[@TheCarPassionChannel]

Definitely will be

[@crix4593]

probably a bit late but does the 6 speed have the gasket and seals behind that plate?

[@kirkharrell7726]

Maybe I missed it, but I don’t recall an episode to follow up on that last dyno day for the NB1.

[@TheCarPassionChannel]

The one where it lost power and then showed terrible leakdown results and needed a valve job?

[@hildamcsulla2741]

Pretty sure my brand new throw out bearing exploded today... funny coincidence! (holding back tears)

[@Atrocities85]

Does a newer miata 6 speed fit into an NB ?

[@andrewatkins1438]

I have a turbo Miata that's quite laggy, if I go a lightweight flywheel will it give the illusion of hitting boost sooner as you hit the rev's quicker? I know boost still hits it's peak at the same rpm but getting to that rpm quicker would make it seem less laggy??

[@shirtz69r]

man greg, you have had some gear boxes in and out in your life. how many do you reckon you are up too?

[@TheCarPassionChannel]

Certainly double digits just on my red NA alone, between upgrades, fixes, and troubleshooting. Way too many 😆

[@boostedrr7205]

I have an boosted 02 accord. 240cc stock injectors, no tune. Using an FMU. 12:1 I heard there only good for a safe 5psi. Is there anyway I can use add more boost safely ? I want to add atleast 10 pounds. But I know the fmu wouldn’t be able to support that much fuel, and I don’t want to spend the money to get a stand alone or tune ?

[@TheCarPassionChannel]

Most stock ECU's can handle about 20% larger injectors so you may be able to cheat a little extra fuel that way, and also the 12:1 FMU might be maxing out your pump pressure, if that's the case you can upgrade the pump but you might actually need a lower ratio disc so the fuel pressure doesn't go too high. Each part in the system affects the others

[@Squirrel765]

Pressure wash that bad boy out. Screw doing it by hand!

[@RyanIncoming]

Whats up everybody its miata dad with miata dad here and we're gonna miata dad lets jump into it

[@zankyzander]

Is there alot of chatter since your using such a light weight flywheel?

[@motomattic]

Any info on the rest of the seals on the trans? Mine is leaking in the middle of the trans near the drain plug where two sections bolt together

[@TheCarPassionChannel]

I do believe that's RTV from factory. If you look up my "Gearheads Garage Collab" you can get some visuals on cracking a 6-speed open

[@joryaugustin7114]

YESSSSS

[@denniskulcsar9778]

How would you rate this clutch/ flywheel for a daily? In terms of drivability and pedal firmness

[@TheCarPassionChannel]

Unless you're 100 years old or only care about having the easiest possible clutch to use, it's completely daily friendly. I wrote up a little info in the description as well since I get your question so often

[@miatafied]

I been wondering why all these companies do the 1.8 clutch and always recommend the 1.8 clutch. Both the 1.6 clutch AND flywheel are noticeably lighter than the 1.8 stuff.

[@TheCarPassionChannel]

Because usually when you upgrade your clutch you need more holding power, so going to the 1.8 size is an easy way to gain extra. But if you don't need it, and you love quick revs, the 1.6 stuff is what's up!

[@histandard31]

KMiata shirt... 🤔

[@theo_korner]

I dont want to sound stupid, but dont you have to balance the crank and clutch assembly for a whole clutch and flywheel change?

[@jhonnilund3.blystkjrskolen511]

You don't balance them, as far as I know there is no easy way to add weight to it

[@theo_korner]

@@jhonnilund3.blystkjrskolen511 you just remove weight by drilling holes on the clutch assembly and drilling hiles in the cranklobes

[@TheCarPassionChannel]

It's recommend yes. The parts are balanced well from the manufacturers so 99.9% of the time you won't have any issues. When I build a whole engine, I have it all balanced

[@endicuddy]

1.6l coming in clutch lol

[@fam4sta611]

Seal pullers are cheap... Just buy one instead of using picks

[@Thomas-rp9qp]

How does your gf put up with all of this?
