IMHO run a blow-off valve, your turbo will thank you for that. You may not get those cool compressor flutter noises, but you'll we well-compensated by the "woosh" of the BOV (that is, if you vent to air). Love the progress you're making!

Will it stay muted after turning off and back on?

I love your videos and been following pretty closely to the point where mine looks similar but hopefully I’ll be done in roughly the same timeframe as yours

I can't imagine a rollbar doing squat if it isn't attached to the frame itself and not just bolted to the chassis. whats that like 16 gage steel in a floor pan?

Id say a blowoff valve would look and sound good and would be better for the turbo. Also stupid question, but you rebuilt the engine ages ago. Does it matter if the assembly lube sits in there for ages? Will it start just the same as if you rebuilt it a few weeks ago?

2:30 What is this bracket called? The previous owner removed it, and put in a shoddy CAI, and now I’m in the process of fitting a better one, but would like to find a replacement bracket to properly fix it, as you have.

This is definitely the best Mx5 build on TH-cam. Even better its in the UK. Just sped run the whole series til now, cant wait to see this thing actually being driven. Great car knowledge from you!!!

Something im toying with on my mk1 is running a custom pipe from the tsi intake into the filter and then on into the turbo

Is mayonnaise an instrument?

I know tegiwa sell 4" velocity stacks that come with air filters on them, so you get the best of both i suppose. The filters look like they would fit in that space easily

My Vote is for HKS, no filtration all the noises

Titanium bell with mesh behind it to protect the spooly

I do like the burnt blue one with the blue pipe. OR how about that massive silver bell mouth but have it chrome gold ❤

THANKS!! Nice clear instructions and easy to follow. BUT ..... I've found some little bits of glass, which tells me that at some time in the past, the window has been smashed. Now, whoever replaced the window has not done a very good job. The original bush was no longer connected to the window and was sitting at the bottom of the guide rail. (I have the new bush from Moss.) Also, the two plastic "window stoppers" are completely missing. Now I just have to find them and the metal bits that the bush screws onto! Any ideas??

Are the bulb numbers the same on a nb1?

M8 that’s how aircraft engine works. Have a look some videos. It’s all about pressure and velocity of the air. The air speeds up as reaching the tighter dia.

What's the difference between the 221 and 441? Iirc the 441 costs £400 more and is like a grand.

Think of all the effort and money you've put in to this build, and the skill you've used to build it. Think of all the engineering knowledge that has gone into the parts you've used by all the independent manufacturers. It's been a massive undertaking and it's become a thing of functional and physical beauty. When you're at car meets or shows, when you're at photo shoots, or if you're standing around B&Q car park with your bonnet open late at night, by all means, fit your velocity stack. But come on, behave yourself. Put a filter on it.

I think that aluminized velocity stack would do ya good with just a short run intake pipe to behind that headlight , but I like the burt look .. I feel the aluminized bigger bell will actually do more for ya as to flow tho tbh .... I just run a turbo guard , but I'm a dingdong anyways lol 😆 🤪... really brotha it's what makes you happy , but performance wise , I think the bigger bell and a short ram will do you the best for flow .. and they make turbo guards big enuf for velocity stacks if you worry of that (street drive mine so I atleast did a guard , but a filter was restricting my flow so that's on you if u go full filter or just a guard ) but yeah man , it's looking good and hope ya can get to rip it soon brotha .. peace and love bro , keep it rad , stay safe , and build on .. l8z

I like the bell-mouth (the burnt titanium one) BUT how are you going to keep stuff from being ingested into the turbo? At the very least put a screen on the opening. If this was my car, I'd put a filter on, no matter how "bad" it might look.

Any pointers regarding the crank pulley with an NB 1.8 auto? I don’t have the option of holding the engine in gear in the traditional sense. The bolt hasn’t been off in 22 years and looks really rusty along with the pulley 😆

How did you jack the car up off the pinch points without bending the body? I tried once and it bent too much

Got any tips for those two bolts behind the wheel arch cover? Couldn’t get them off for the life of me

It’s kinda insane that there is a very limited amount of air intake kits that aren’t expensive but they are getting harder and harder to find

Looking to purchase the kit soon for my mk2.5 svt, i'm aware they don't come with ABS brackets and i can't for the life of me find any solid info on how people rectified this. Did you completely remove your abs system or just disconnected sensors and fuse as stated on a few sites? 😅 Keep up the good work dude 👍

I don’t know if this will help anyone but when taking off my hoses to replace them a lot were seized. WD40 and a screwdriver to work them off done the trick

Thanks for the video, very helpful. Its 29mm not 27 BTW!

I'm dreading doing something like this too, I'm at the level of your old coil harness for now 😅

I know it's not really the focus of the video but do you mind if i ask about your ME ecu? Do you think it's better than mega squirt? I'm in the middle of a build and trying to see what someone that has experience thinks about it?

As a turbo miata owner, this is a game changer for servicing

That is amazing work. Your capabilities on a technical level are tremendous! Keep it up, learning a lot from you over here.

Right on bro ...I ha e mine tucked to the sides aswell , but I did not shorten and clean up like u did .. I just tucked the extra 😅... ya deff did a rad job bro and clean too 👌🏽..mad props brotha .. peace and love bro , keep it rad , stay safe , and build on ... l8r brotha and keep having fun

no grease??

Am I insane to buy an MX5 with limited ability to fix the thing myself? Probably... Are they all rotten? probably.. Do I want one.. yes.

Imagine not saying the sizes... could have been a perfect tut

Mannnnn you a life saver! Thankyou so much!!!!!!!

Every product I purchased from ultra racing doesn't seem to fit properly ' or needs some type of adjustment ' don't think they even bother to check the fitment ' so now I have swapped it all out for hardrace items

Bet your neighbours wereloving that 3am cold start 😂😂😂

Was following this vid, and at 6mins 30 you swap a hose for the brake booster, is thst one meant for that? Does it have a valve in?

How do you get that twist action out if my window does the same?

malaka, simply amazing stuff here.

But how did you plumb in the return line to the tank?

Nice - but at £30 seems a tad expensive!

Your video was so helpful and couldn't have done my brothers mx5 without your knowledge. Managed to only snap 2 bolts both sides using gt85 then wire brushing. I had no idea how to get the last bolt that is hidden holding the front r arch to bumper. You sir are a legend. I love mx5s but not as much as rust does 😂😂😂

Clear and to the point!! Included useful information like torque specs and bolt sizes. Definitely my favorite style of mechanical instruction video. Hope you guys keep making them!

Hi It looks like the stock intake to the air box is more or less in the same place as the new one. So effectively, all you are doing is moving the filter from mid flow to the start of the air flow. How or why does this make a difference. I believe K & N filters provide better air flow than stock. Does the foam filter provide even better flow?

was that just sealant you used on the top of the engine in between the head and the head gasket?
