- An often overlooked part of adding character and pace to a track/spirited road car! So many cars from factory come with engines nerfed by super long gearing but there is often a way to pick and mix oem components to wake things up!
One thing to note if yo uare swapping the 5 speed out for a 6 speed that I didn't mention in vid is you MUST change to a 6 speed prop shaft too... I found out too late haha!
Edit: Stage 3 not stage 4 clutch, my bad!
Don’t have an MX5, still love these videos so much.
Haha honestly made me smile so much reading that. Thanks bud :)
Arhhh ... I love my 2.5 swap nc2 with 5 speed & 4.1, it's great around Blyton, I'm guessing I could try a 6 speed for Silverstone but hey I'm a novice 🏳🏁 I wouldn't know 😲.
Great vid, keep them coming 👍🏻
Excited to see what a properly built 2.5 is like in yours bud! I bet it’s bloody mega!! I wouldn’t rush to do it but maybe at an opportunity when the box needed to come off for another reason it could be worth a go! You are far from a novice mate ☺️🙌
Awesome video, talked me down from ordering a lightweight flywheel I've been eying for my NC, and it's for the best.
Thanks Ricardo! You really do have to weigh up the pros and cons don't you! All comes down to how and where you most like to enjoy the car.
Is it worth to modify an nc 1.8 or it’s better to change it with a 2.0 and then start the project
Such a tricky one but personally, I would start with the 2.0 sport. You can get a lot of enjoyment out of the 1.8 though... I'd make sure it has the LSD before spending big money on coilovers etc... Luckily though if you did find you wanted to go for the 2.0 you could always take off the mods you had put on the 1.8.
@@CIRCUITDRIVERCARS because I bought in 2018 an nc from 2006 1.8 totally stock for 6 grand . And after 4 years I’ve done just maintenance and the muffler . But when I start thinking about modify for better performance I always change my mind because it has a lot less than the 2.0 , starting from the shifter that has 6 instead of 5 shift , the differential , the power , the sway bar (duomi) and that would be crazy money to add just this things before enjoying better coilovers and everything else .
Hi there agin I have been looking in to the Diff swap to a 4.1 a lot. Can I ask at 70mph what is the rpm I only ask as I saw a new UA-camr in USA whos swapping in a RX8 4.44 diff. He’s doing this as a part of swapping out his hubs owing to a fracture issue😱.
Looks scary
Hi John, oh not sure as I had the 4.1 already in mine and just swapped the gearbox over from the 5 to the 6... Regarding the rpm at 70mph... I sold the car so can't tell you. All I would say is don't worry about it being ott or too high rpm for cruising... It's only a slight improvement over being revolutionary. In 6th cruising at 70mph will feel fine :). We had a 4.7 in an old mk2 mx5 and that was chaos driving all the way to Germany ahha! My MK bike engined kit car was also geared to top out at 118mph.... 6th gear you'd be cruising at 9,000rpm ahhahaa!
Great video Will - full of info. Totally agree with you about the gearing. I've kept the 4.1 and put in an aftermarket LSD plus a lightened flywheel in with my turbo mk1; so much more crisp on acceleration than a 3.6 or even a 3.9 (although it's a bit buzzy at motorway cruising speeds!). I'd much rather have the extra torque from the better gearing than a quieter car when cruising ¦:¬D
My organic-faced stage 2 clutch is still holding up but perhaps I don't do so much hooning around as you!!!
Looking forward to seeing how your mk3 does after the tune......if it's not enough.......they do take well to a turbo!!
Thanks Phil! Certainly sounds like we are after the same thing/experience haha! Yess incredible how important it is considering how overlooked it is. So many cars are utterly ruined by gearing... the manual v8 m3 being one of them imho! Running into issues at mo with the mk3. An odd misfire hiccup! Currently trashing the love for it 😅🤮
Yeah either people don't even know it or don't want to do it for some weird reason.
Have a 6speed and 4.1 diff in my NA and love it.
Mad isn’t it! Maybe just seems like a lot of effort without understanding the benefits! It can be hard to explain it to someone the real world benefit. Much easier to hand them the keys and let them see for themselves!
You're making me think what could have been about putting a Spoon 5.3 in my DC5 instead of just selling it on. Nevermind, that is being sold soon for a M240i anyway 🙄
Atleast in a FWD car it's a chunk more involved to do over just swapping a rear diff over like in the RWD stuff. Congrats on the m240i.... belting choice, I adore my little m135i!
@@CIRCUITDRIVERCARS haha you say that but I feel like I'm going to want to fit a mechanical LSD to the 240i anyway 😆
@@aevans148 oh but ofcourse! I have a Wavetrac and Powerflex inserts on the workbench ready to go in the M135i this weekend haha! Never ends!!
Got any info on the DC5? I’ve been looking for one myself for a while
Where did you get a 6 speed for £300?😮
Was a pre 2009 one so not the perfect option but certainly felt a bit of a bargain until I fit it. Unfortunately it was very whiny/noisy so I probs got what i paid for in reality haha. Hard to simply find one for any money though isnt it!
5 speed final drive with a proper plated diff would probably be my first mod.
Yess! That would be fantastic. I've just spent my money on a wavetrac LSD for the M135 instead haha.
@@CIRCUITDRIVERCARS Haha. Just spent mine on an m-performance diff for the M240i 😃

Question as you prob know better than me.
I have a spare 3.7 LSD and 4.1 open. Can you swap te 4.1 final drive gears in to the LSD or is this not possible.
I only ask because I just can’t source a 4.1 lsd
Sorry bud, I don't know myself but you would assume so! Will ask a friend who often rebuilds them and get back to you. I'd imagine it wouldn't be cost effective at all.... But if you are struggling to find a 4.1 and there is no other option I totally get it!
@@CIRCUITDRIVERCARS ty would be appreciated… I have a spare LSD with the 3.7ratio and coz I know the open diffs are cheap as chips I was hoping I could francinstine it together as a experiment.
Good luck with 3/4 speed shifts. 6 speed gearbox NC1 specificly is terrible for shifting at track. I have one and i'm going to swap 5 speed.
Ahh not good! Maybe upgrading to the 09 onwards is a good option as they revised them didn't they.
@@CIRCUITDRIVERCARS They are better, but i can't find any for sale in EU.
