Cool. I have a R53 throttle on my R50. It fits on the stock intake, but you have to enlarge the throttle's mounting holes so they mate up with the intake. I used a R50 throttle body spacer as a guide so I could check my progress as I went. So, I've got the R53 throttle with a 1" spacer mounted to the stock R50 intake. I used a 90-degree elbow for the vacuum line connection, as the connection's in a different place on the R50 throttle than it is on the R53 throttle. My car makes 145bhp. Planned future modifications are a ported head and, if it will pass emissions, an individual throttle body kit (e.g., Jenvey). That's about as fast as a R50 could ever be (and pretty expensive, too!) but, if all I cared about was horsepower, I'd just go out and buy a Dodge Hellcat (screw the R53)! For me, the fun is in the tinkering, and, of course, the driving. Cheers.

Good vid👍👍 following this when I do mine

Well done so far , it's good to see what you can achieve when you give it a go. Many things have been created by us in our sheds, its what us Brits are renowned for, good on yer.

Just a question on the vacuum lines. Where did you run your brake booster line? Also what did you do with the other crankcase line that you broke? Thanks

Hi Christian, this one of the mod i would like to test, got some R50/53, one is a Cooper with a S front face for the air (like you explain at the end of the video) and some other mods. (cam for 3000-4000rpms), 1mm panished cylinder head with a specific chain tension bolt and bbio ethanol with S 330cc injectors and remap of course) Would you able to supply the adapter ? If the connector is the same, perhaps a S throttle (bigger), it can be rescale and managed in the ecu

Did you ever solve the breather problem. Out let from head and the vac line for brakes???

Hi mate where did you get the stainless block from?

Where do you run the brake booster line?

If anything the r53 supercharger manifold is gonna make your car loose power in ALL rpms except for maaaaaybe above 6k you might make a few extra hp and tq. No WAY those runners are tuned correctly for the na engine , if anything you need a much much larger intake to hold air to send in the engine as soon as you hit the throttle .

Hi how did you fix that with the original air box? Do you have some pictures maybe?

Where did the break booster pipe go from the breaks on the manifold as I got r50 doing the same as you

Did you replace the crankhose breather?

How did it run once put together?

Mate great video , I'm in the same position as you , not many people want to mod these engines but I'm interested in how much power can actually be had from one of these , im well up for a turbo conversion

I like this mod. Good work If you could do this again would you do anything differently? Did the map sensor and throttle body work as normal?

a bandsaw would do wonders. Grinders suck at getting through thick aluminum.

Have you had any issues since you did tha mod

Anyone building the adapter plates yet?

Hello Chistian, great video. I would like make the same to mi mini R50, could you tell me how long the aluminum addition is? And what do you need to change or adapt to make everything work correctly? Thank you

Super Broo 🏆 👍👍👏Tell me which engine oil to put in my R50 on the watch is 213,000 km

Hi mate. I’m planning on doing this to mine. But I have a question? The back hose that’s hanging next to the throttle body, whereabouts did connect that to? Cheers

Quick question where did u put the vacume for the brake booster

If you make them let me know where to buy one at! Great job

How much faster. Changing manifold

Did your standard cooper ecu still work or wat way u go about it

Got some valve ticking going on

Would you recommend this mod? As I’ll be doing the same and putting the r53 throttle body on too!

I done the same thing to my R50. But i did a much nicer job. Even machined and tapped the intake manifold so it could take the vacuum lines properly. I also used an R53 throttle body .. Shame i cant post a photo.

Did it run alright after? No need for a tune?

Hey mate 🤙 good vids I also have an R50.. have you noticed a significant difference in power ?

Where could I get the adapter for the throttle body from thanks

Did this on mine. Tbh ur better off running the stock intake, u have no low end power, acceleration is shockingly bad (almost like it was a 1L) and it has a massive flat spot between 3k and 5k rpm where I can’t accelerate. Idk if I did something wrong but it also idled like a dog😂

How much $$$ you can sell me one same adapter ,??

Salut Jolie adaptateur tu peux m'envoyer 1 SAIT bien passé, ell6 donne mieux le métal et plus Jolie merci de nous appelons à prendre soin de nôtre mini . A bientôt jatten votre raisons amitié greg
