Citroen C1 Bigger Injectors Installed, C1/Aygo/107 Yaris Injectors, Easy/Cheap Performance Upgrade 

Haha. It’s actually one of the better mods tbh

@@StupidBlokeStupidVideos yeh I watched the second video I take it back 🤣🤣 just done the 8 quid reversing sensors, keep up the videos very entertaining 👍🤣

@@jcreswick haha another sic mod. Thanks mate.

Exactly! Easy to drive and too slow to hurt yourself in.

Yes I looked into those first but need the duration changing as they won’t trim. 115bhp n/a?

@@StupidBlokeStupidVideos yes, tuned an dynod at mana performance it is pushing it a lot so keep that in mind, it like to murder the exhaust valves quite a bit

@@alexashurst512 that’s some going. Didn’t even know that kind of power had been done N/A on these. What does it rev to? What torque is it making and where in the rev range is peak power?

@@StupidBlokeStupidVideos revs to just below 8k, peak power is at 6900, the torque is 152NM not an extravagant improvement if you think about it lightly but when combined with such a low weight it rlly is a blast on A and B roads

Sadly the gearbox did decided it no longer wanted to hold its self together last night so she’s currently sitting in my unit

Yea almost 70 in second. It’s long geared for a 1.0. Gets to about 35 in 1st, 65 second and 90 in third! That’s the same ratios as my old Volvo V70 T5!

My 330d 6 speed only does about 50-55 in second.

@@StupidBlokeStupidVideos my mum's old 106 was the same very long 2nd. My current is a 6 speed too. Not sure how I managed it... one day I was racing someone and hit such a nice boost curve I was doing 110 in 4th 😂 suddenly realised.. then 5th only goes up to 125. 6th will do me good for 140 bit it whines like a bitch so I don't push it that hard that often any more. I used to daily to work at 130mph for 3 years straight. Absolute tank 😆😆

@@MaNNeRz91 what car is it?

@@StupidBlokeStupidVideos Renault Laguna with the widely used 2.0 DCI in all the Nissan's Vauxhall's and Renault's. I bought it because I wanted a reliable turbo diesel that was cheaper to insure than most. It was cheap for its mileage and condition. (89k 1 owner) I gave it absolute abuse for 3 years (now 175k miles) and the turbo started showing signs of oil passing the seals (weirdly thatwent to the air filter and not the intercooler) 🤯 I've stuck a better turbo on it and decat. Egr delete and all that good stuff. Still pulling strong.

I asked him,.. but he said he’s too afraid and that he probably wouldn’t be able to handle the power.

@@StupidBlokeStupidVideos 🤣🤣 serious tho considering buying one of these as a rumabout

@@jacko2815 do it.

@@StupidBlokeStupidVideos I had one as a hire car in Italy with all my luggage 2 cad seats n kids n wife I fucking hated it but was up and down mountains in it was nt the car you wanted I went to the city in Italy in it and we great car. I'm in London so be spot n here as a rjmabout

Yea it’s unusual for them to have that but it’s just part of the filter. Different manufacturers sometimes change them slightly, but I can’t remember what make it is though.

@@StupidBlokeStupidVideos Thanks. It is quite unusual, yes.

I had already cleaned the old injectors previously. I show the process in more detail too in this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LXz0aCp4zOA.html I’m actually currently doing some more in-depth comparisons of the standard vs Yaris injectors for a future video too.

@@StupidBlokeStupidVideos ah okay, I'll check it out. Cheers.

Definitely yes. I only drove it for about 10 miles after fitting them before making the video, but I’ve driven it a bit more now and it’s not massive but a definite noticeable difference. It’s also smoother. I’m surprised to be honest.

Overtake? You mean 'keep up' surely? I'm not even sure why these roller skates need/have mirrors? By the time you look at whatever's behind you, it's already in front.

@@sally6457 not realy. I drive on autostrada and it is ok. In city it is great. I can easy overtake a vw golf 1.4..... or a sheet corsa 1.2. Top speed it is no more then 165 km/h tested by me but it is ok.....

@@dudurosca273 while your trying to overtake you are blocking my lane! Hahaha!

@@dudurosca273 These stock aygos fucking shit on corsas. Every 1.2 I come across gets shat on. A lot of 1.4s get trashed aswell 😈

The ecu can be remapped but this hasn’t been, and I’d have thought similar,.. I’d have expected any differences just to be filtered out by fuel trimming but they just don’t seem to be. It’s done probably about 1000 miles or more with them in and definitely runs better on them. It’s mainly noticeable at cruising revs than anywhere else. It is also noticeably worse on fuel though.

Yeah it will trim it down, along as the difference isn't too large it should be fine

I doubt they would notice it to be honest mate unless they were looking for them, they look the same but green.

Sorry mate, no idea

Sorry mate I’ve not got the number. The way I found them was to search for someone breaking a Yaris TSport on eBay and message the seller to ask for the injectors from it, but these days they seem harder to find and more expensive. Probably cos people wanna buy them for their bugs 🤣 And thanks mate!

Yea I agree that I could have been more thorough with the comparison.

Not sure if you’ve seen already, but I did some more measuringtons. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-a3jBTvyxZm8.html

Not much. I paid about £40 for the injectors second hand.

Some of the later ones did have green injectors, but they’re not the same as the Yaris ones.

@@StupidBlokeStupidVideos I thought as much, where did you pick yours up. They’re dear as everywhere I’m looking. Thanks

@@jackdyet2902 I got them off eBay. I just typed in Yaris T-sport braking and message the seller asking for them

or maybe any other more common vehicles. that would fit.

Not sure to be honest, but I’m pretty sure the duty cycle would need adjusting by mapping if they do fit.

@@StupidBlokeStupidVideos i did found 2NZFE injectors (1.3 engine) i'm pretty sure they are the same as 1.5?

@@Jelle102 honestly not sure, but they could be.

What injectors did you try? Sounds like you could have gone too big and over fuelling?

@@StupidBlokeStupidVideos exact same ones you used

@@Thatsilveraygo didn’t have any air leaks around the injectors did you?

@@StupidBlokeStupidVideos might have done, the o rings aren't reusable

@@StupidBlokeStupidVideos that and I didn't cut down the slot where the o ring sits like you did

I think I would need much much bigger injectors to run on ethanol, probably about 150% flow rate but I’m not sure. If I could get hold of some I’d throw it in the give it a try though 🤷‍♀️

@@StupidBlokeStupidVideos Its maybe to late answer, but you need about 30% bigger injectors to run on bioethanol/E85. With ethanol, the engine will run better due to a high octane rating of 104. The engine internals will be clean so do the hole fuel system. Its gona be more reliable and have more power, and ethanol makes less wear on the engine than petrol

It’s a 2007 Citroen C1. If you have a Peugeot 107 then it’s effectively the same car as yours, same engine etc. The injectors are from a Yaris T-Sport

@@StupidBlokeStupidVideos Thanks a lot, great work!! Take care!!

@@evka3220 cheers mate, and you too.

I didn’t get the part number, but the injectors are from a Yaris 1.5 T-Sport. Around 2004 model. Probably better to get some used ones out of the correct car than buy new aftermarket ones I’ve seen on eBay in my opinion.

@@StupidBlokeStupidVideos Thank you

It should be easier for the Ecu to get the mixture with the bigger injectors than it was with the standard ones

that silver aygo has it running at 97/8 hp and my C1 is running about 90hp but needs more tuning to get the correct a/f ratio and a proper exhust that isnt just racing headers.

@@dillonlee3229 Can you explain the mods for C1?

That silver aygo has a channel about his mods as well as TSA performance having an instagram page where you can buy the mods. my C1 is running near the same setup with some diffreinces. my C1 has tspot yaris injectros, piper racing exhust, full 2.5" stainless exhust. bigger coil packs, stage 2 flash tune and a TSA Induction Kit (Non A/C). this set up could do with a dyno tune but im unable to fine the people to do it where i live so it does overfule on the tune but iv changed cars while i put a turbo on it.

I don’t think it would make any difference with that tbh, but it would probably last longer before getting clogged up

@@StupidBlokeStupidVideos If you are willing to try it I did some research and have suggestions

@@isymdvrI might give it a go next oil change

your pcv valve could be blocked, or its just reaching that age, mine is at 150k miles and i use a bit thinker oil and it stops it burning as much

@@dillonlee3229 i have changed the pcv valve and yes i do use thicker oil. Would an oil catch can help minimising oil consumption ?

Yaris T-Sport 1.5, about a 2003 or so iirc

I’d love to do something like that but I’d have to get a lot more views than I do currently, to help pay towards it 😂

@@StupidBlokeStupidVideos I feel you lad, but it could make for one crazy ride! Love your vids, keep them going :)

@@z-trip5457 I’d love to fit a supercharger or a turbo, I could get a cheap shitter off eBay for couple of hundred quid but I’d never find the time to do it way things are at the moment. Maybe one day and cheers. As long as I’ve time to make them and stuff to film, I’ll keep them coming 🙃

@@StupidBlokeStupidVideos I heard good stuff about the amr500, cheap af and not too hard to install, who knows!

@@z-trip5457 yes. I’ve looked into these. About £200

Thanks. I don’t have a link to the injectors unfortunately as I got them from a breaker on eBay. I just searched for someone breaking a Yaris T-Sport and messaged them for the injectors. I did however make another video doing a more in-depth comparison of the performance gains it’s. Here’s a link to that if you’re interested: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-a3jBTvyxZm8.htmlsi=S9qyt-1pASJ-d9oL

@@StupidBlokeStupidVideos yeah no worries, I have watched both videos and am looking at getting some of these for my '08 107. Will find some on Ebay and post here for others 👍

@@harveyfisher23 I’m not sure if these are the right ones, but yea if you find a readily available set that work, deffo post the link on here www.ebay.co.uk/itm/225790379957?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=wx8rzbjssus&sssrc=4429486&ssuid=B24T_G0JTKS&var=&widget_ver=artemis&media=COPY

This one even has a 3 jaw chuck for auto centralisation too!

What year is your car? I’ve not heard of anyone else having that issue and it’s quite a popular mod on these cars. Was it definitely running rich and not lean? I’ve seen people have lean issues due to the seals not fitting right and drawing air in.

@@StupidBlokeStupidVideos 2009 mate, it was blowing white smoke, smelled of petrol and exhaust tip was black

@@StupidBlokeStupidVideos is it one of those codes where you have to clear it with a reader?

@@gregcornes8912 interesting. White smoke wouldn’t indicate overfueling. It was probably just condensation if it was cold. It’s not a big job to fit them. I’d reset it on a code reader and maybe try again after a bit of a drive.

@@StupidBlokeStupidVideos Only problem is I'm trying to get it through its MOT🤣

This is something I have already considered 🤣

only after upgrading the brake and suspension systems to cope surely?

@@rodneyhull9764 probably not a bad shout but tbh the brakes are actually overkill as standard anyway.

@@rodneyhull9764 springs from a biro and Shimano v brakes would be an upgrade. I suggest the old Reliant method; find a speed trap at the bottom of a long steep hill, wind the window down and shout....meowmmmm, as loud as you can while you pass by. Send your parking fine on a postcard to, PO.box 2 slow 2 FL45H. SP30 TKT, London. Hahaha

You’ve just got to find someone breaking a Yaris T-sport to make sure to get the right ones but prices seem to have gone up since I made this video

@@StupidBlokeStupidVideos : I found a 220£ option and a 20£ option. Any idea why the huge difference? Which one to go for ? Links in the following

@@sayanpal9491 I think since people realised you can fit them to these cars, the prices of used ones has rocketed.

That’s a good idea.

Hi, they’re the standard injectors from a mk1 Yaris 1.5 TSport

@@StupidBlokeStupidVideos ahhh sweet can you happen to pm a link with on fb or Instagram with the ones you bought cheers

@@Tiggerr88 I would but I don’t have a link as such. I just searched eBay for someone breaking a Yaris T-Sport, and messaged the seller asking if they would sell me the injectors.

@@StupidBlokeStupidVideos cheers much appreciated

@@Tiggerr88 no problem mate

They have now 😂

Good question. Cars from the factory are set up as a compromise, and usually performance is held back in favour of fuel economy and more so emissions. These definitely made a noticeable difference without even mapping them in.

Get e85 fuel with no reprog 😉

I’m hot on the heels of Chris Fix and Garage 54, and thanks for the help 😃

Stupidity can run around the world, before intelligence gets it's boots on!

It’s ok, I’ve just counteracted that by uploading a really unscientific video.

😬. I’ve spoken to you on the Facebook groups about this earlier today didn’t I? Keep us updated how you get on!

@@StupidBlokeStupidVideos Yes mate, and I will, hopefully it's sorted out soon

Do the injectors alone not turn the c1 into an actual Yaris T-Sport?

@@StupidBlokeStupidVideos got to admit it would be an exciting engine swap? Not sure about the handling but it would make the car fly.

@@Mybwain if I had time to do it, I’d probably consider something like that. I’d like to turbo the shitter for a laugh, but time is the enemy of anything like that at the moment.
