While I was out "shopping" at the salvage yard this morning for R53 parts, I came across an 2003 R53 that had appeared to have had the fuel system recently updated/upgraded.
The Fuel rail was shiny chrome. Upon disassembling I discovered these Siemens Deka (2531, part# 0391511) Injectors had been installed.
I tried cross referencing/googling and came up with: Mini Cooper Fuel Injector Jcw 380cc
I have an '04 R53 w/mild mods: 15% pulley and CAI....
A couple of question"s:
Can anyone confirm that these match the description in the link (JCW 380) ?
Can I install these injectors or will I have to also get a tune?
Any tips for cleaning the injectors or further recommendations?
Yes, if memory serves me, that is the Siemens equivalent part number for the JCW 380's.
While a tune is obviously recommended, they will work without one, the fuel ratio difference between the 380's & 330's is close enough that the ECU can adapt well enough.
Standard cleaning methods should be enough if the injectors were still installed.
Those are definitely genuine JCW injectors by the looks of them.
I've only found one set at the boneyard, off of a late 2004 JCW,
here's what they look like:
Note the 2 holes on end,
most all of the cheapy China knockoffs use 4 holes, and also obviously lack any identifying makers mark.
The genuine JCW injectors are still insanely expensive,
ridiculously overpriced in my opinion...
...side note:
my local dealer Mini of Kennesaw recently closed which bums me out, now I'll likely begin a relationship with Global for acquiring OE parts, do you happen to have any experience with them?
Just asking for curiosity sake.
Hey - Thanks for the speedy reply!
I forgot to ask: I can imagine gas consumption will be affected - Notwithstanding; with these injectors, will there be a benefit in hp?
Although I have been experiencing a few hesitations/misfire at times (when hitting the pedal hard), My Mini idles and run/preforms well. I do tend to think it runs a bit rich from the smell coming off the exhaust.

Awesome! Thanks for confirming.

Yeah - When I started googling...I first thought the price was for a set of four....until I saw the notation "per"

I'm kinda sorry for you, to hear about the Kennasaw branch closing. I developed a great relationship with the Mercedes Benz service dept. - So I can understand how you might feel.
However, my experience w/Global was less than satisfactory. I didn't feel they were very thorough and I suspect them to be a "little" less than forthcoming ($$).
I kinda have a nose for b******t. I really don't like being "played"......But, hey - that is just "ME". (Orlando Mini was not much better).
I think BlwnAway is correct about them being close enough to the stock 330 that the ECU will adapt, but a tune for optimum performance would be preferred as he noted as well.
Bummer to hear about Global, I've heard some stuff so was a bit sketchy on them, may have to make the trek out to MoG?
Dunno, but you're right about how great it is when you develop a good relationship with the parts dept., the folks at Kennesaw were awesome and I'm gonna miss them bigly.
I will definitely have to learn more about tuning. Not even sure where to go to get a tune(?).
I used to think I was a "car guy" (back in the day). You could only imagine my surprise when I bought my new Mini, popped the hood and asked "where's the distributor cap?".
Not trying to sound like a jerk - but I have been pretty disappointed in my experience with local independent BMW shops recently. I may post some annoying noob comments/threads around here; but rather than disparage mechanics - I would rather learn and twist my own wrench. The folks here on NAM have helped me tremendously!

Factory tunes rich, so not surprising.
As far as fuel millage, it really depends on the adaption of the ECU, if your parts work well enough together that the ECU can fully adapt, millage won't change much at all.
But you WILL be safer at WOT in the high RPM's.

Same here buddy!
I came from mid 80's Saabs, drove a C900 from 1991-2018, so I was used to distributor caps too LOL
I feel like a moron with computer tech stuff and will deffo be in need of assistance in the near future for tuning.

Thanks for pointing that out. The ones I scored have the authentic 2 holes you mentioned. Good to know.
Even though they were super clean from the pull; I cleaned them up today. They look almost brand new! Not sure how to clean the internals. I tried blowing 15lbs compressed air through the inlets via small tire compressor. 15psi is probably insufficient.
I'll probably pop these in when the weather is nicer and can afford a new fuel pressure regulator when I do the whole install..

BTW: Did I mention I paid $30 for the 4?
If you search online there's tutorials and how to make a simple electrical thing that you hook up to the fuel injectors and it will make them pulse on and off so that you can blow brake cleaner or fuel injector cleaner through Em then while their pulsing

I like the simple DIY "valve stem" connection to the injector rig the best.
On another note: Is it really necessary to spend $60 on a set of (8) 'O' rings?
There are some that are less expensive but .....?
Any experience with 'O' rings failing?
First of all a (belated) Happy Holidays!
I don't mean to drag this discussion on, but rather than starting a new (related) thread...
While I'm waiting on the 380cc injector kit, It had me thinking about my other mods:
!5% pulley, 2-1/2" CAI, Colder NGK plugs & wires.
While I do intend to get a tune after swapping out the injectors, I was wondering with the added fuel delivery; Would the colder plugs be necessary? Or going back to the standard (or)"hotter" plugs.
I suppose a tune may provide the answer.
Just thought I'd query NAM in their experience.
This thread got me reading some of the older threads about 380cc injectors and looking at the available choices. I came across Bavarian Autosport injectors on the ECS website. Does anyone here have experience with them? I'm generally leery of very low-cost alternatives but I think Bav Autosport has a decent reputation. https://www.ecstuning.com/b-bavarian...3537574132kt1/

I've been running the NGK Iridium 7s for years. I ran the 8s for years until I started getting a rich condition code. Switched to 7s and it went away. I also have a 15% pully JCW intake and Miltek exhaust. I have JCW 210 tune from the dealer.
The short version:
Dropped in my 380cc Siemens injectors yesterday. Mini idles perfectly. Runs great (as usual). No codes.
The long version:
Whomever coined the phrase "Patience is a virtue" may have had a point. Being the rather bored and sometimes restless person that I am; My mantra has always been "Patience means Never". I even state it on my Mini.
I was going to wait until Spring but also been waiting for a warm enough day when I could get back to doing work on my Mini. I don't do well in temps under 80°F. Late yesterday I decided to brave the 52° temps under windy conditions, and drop in my 380s'. Took me 4 hours. Most of that time was due to my incessant/insistence on cleaning my engine, nooks, crannies and parts. (I use engine de-greaser and a AA battery powered toothbrush). Everything was going smoothly thus far. Double checked and torqued everything. By the time I was almost done, the sun was setting and the temp was down to 45°. That's when I started shivering, loosing intercooler bolts and my last 30 torx bit, down the fan/engine bay. Never to be seen again. Had a couple of back-ups wisely retrieved from my salvage yard picks. Confident in my workmanship; I fired up the Mini and checked for fuel leaks only to discover a deluge of fuel pumping out from beneath the intercooler. Although I heard a click/snap when connecting - I suspected the fuel line was not properly seated. Left it for the morning. Re-snugged the fuel line today. No leaks. Took it out for a 12mi spin on the hwy. Really didn't notice much difference in performance gain. I did however at one time, noticed I was cruising @83mph, @5.5rpms in 3rd gear. That's something I don't often do. Although, it has been said; "The advantage to the larger injectors would be of greater benefit at higher gears and higher rpms".
EDIT: My mistake - 83mph @5.5rpmsin 3rd gear (not 4.2rpms). Twisted the engine up to 110mph for a short sprint this morning. Paid more attention to the tach, gear and speed this time.

s'bout right. I slide into 4th just under 90 "merging" onto i75.
