- BMW M2 N55 Dorch Stage 2 HPFP Upgrade: Full E85
In this video we install a Dorch stage 2 high pressure fuel pump upgrade to our friends F87 M2. After running the Bootmod 3 e30 OTS and suffering significant HPFP drops he knew he needed a better solution for the direct injection side. He is planning to switch to a custom full e85 tune, so hopefully this does the job.

Very Handy video mate!! Thanks for the info
Great videos guy. I have a M2 with 165,000 ks on it and just start modifying it now. Just ordered the stage 1 Dorch and hope that I am happy with the result. I am in Bris and hope to see you at the track one day
How did it go bro did you like it?
Would love this on my N55 M2 and just a pure stage one turbo to extend power at the higher end of the rev range. Good compromise for good power and reliability I would have thought.
They are, they really run like a stock fuel system just maintain a higher pressure under load.
Great video 👍🏾 would be interested to see what it puts down on a dyno on stock turbo?
Great video, nice footage for DIY !!! You actually inspired me to go ahead with this dorch solution. I just finished installing this same st2 kit on my 2018 M2 !!! Engine is running nice and smooth. No leaks. My only concern is regarding the noise of this new pump. The OEM pump didn't do any noise at all. Does your dorch pump make a little bit of noticeable noise with the hood open ? Does it sound like a sewing machine ? Would that be normal ?
There was a slight change in sound. My recomendation to be safe would contact dorch on instagram with a video clip. Tell them ZeroTo60 sent you :P. They were very helpful for us.
Great decision to upgrade the hpfp but surely he’s not just running the bm3 out of the box tunes.
He ran the BM3 tune, before filling up with e85, he's got a "jordan tuned" map on it this second, that they are going through the revision process with right now. Im just editing the first drive vid, and it feels pretty good on the base map already.
Is the hpfp a mod we should do for the N54? Don't forget to text/email a contact for Sunday☺ good luck with the cannonball, hope they let you back in..
@@ZeroTo60Tube awesome.
@@ZeroTo60Tube Upload more videos of this thing! Deciding between M140 (needs LSD but has B58) and M2 (LSD but N55)
@@danielr9154 Tough call. If you want a nice car to drive through the twisties, slide a little, hoon about etc, the M2 N55 with a stage 2 tune is still a rapid car and will be better to drive than a 140i with an LSD. If you want a muscle car, something to just punch in a straight line, the occasional traffic light drag race, just a mean street car, M140i with the B58 has more potential. This M2 is simply an amazing car to be in, there's a lot to be said about an actual M car.
My tuned N55 135i has developed a Rod Knock on weekend - just randomly started at 105K. Not sure why but I guess you gotta pay to play. Will be fitting a low km M135i long motor - combination of both motors I guess sump HPFP, injectors etc. Will be an interesting swap. If I was a bit closer you look like the perfect chaps to do this swap out... Enjoy the videos. Channel has come such a long way. My BMW enthusiasm is currently waning however, with luck, new motor might cheer me up and seeing some BMW success on your vids give me some faith :) Might even look at a bit bigger turbo - your cheap turbos seem OK...
Damn that sucks man. I really hope the N55's dont turn in to an issue prone motor when they start getting higher milage. How often were you doing oil changes on it? Also you're brisbane right? Heading to rolls on Saturday night?
@@ZeroTo60Tube No mate I am in Mackay Central Queensland. M135i has forged crank i believe so it will be an upgrade I guess... i have only had car a little over a year. Had full BMW service history as well. seems like it is a bit of a problem reading the forums.
@@ZeroTo60Tube I live in Mackay North Queensland. F20 has forged crank I guess. The car has full BMW service history. I see a bit of it on forums but who knows.
As a heads up. BMW servicing is very minimal. I really don’t like how little they change the oils. Anyway hopefully you have plenty of fun miles out of the new motor!!
@@ZeroTo60Tube Thanks mate. Here is hoping yes. Yes their servicing schedules do leave a bit to be desired. The engine is still with no noise at idle and no knocking under load. I considered just putting a rod bearing kit in through the oil pan however advice is that usually once knocking has started damage to rod or crank journals is most likely.
How long does the change take
B58 you can do it without removing intake manifold as its on the exhaust side! I was eyeing the FP off when I did a high flow catted downpipe.......I reckon sub 2hr from start to finish :D EDIT: Did you check the intake valves for carbon while you had the inlet manifold off?
We did check the valves and they are pretty clean. Surprisingly clean. A little bit of dark colourisation but zero build up.
How about manifold gaskets?
They were still nice and proud. My n54 gaskets were 155,000ks old and still fine when I changed them. Wasn’t expecting any issues with these being so new.
Hey I really love your guys content on this m2! I’ve recently wrecked my 600hp evo and was looking at getting into one of these. My goal is bolt ons tune and e85, for some road course fun.
are injectors also required, or just the fuel pump and supporting mods? Cheers!
600hp will require a turbo upgrade. Fueling you may get away with one of these pumps depending on what fuel is being used. In fact 600 at the crank will be fine. 600whp may be right on the point of needing port injection.
Zero To 60 I appreciate the reply! I’m not looking to push that much again, I just have e85 very accessible where I live and I enjoy driving around daily on that because I have a very short commute as well.
Hi high pressure line and low pressure line , use OEM one or come with Dorch new one?
Because the video only replaced the HPFP, thanks.
I think the kit does now come with a LPFP line. This i had to make one.
@@ZeroTo60Tube So Dorch HPFP kit didn’t come with all what I need, by the way I only need running 93 octane Stage 2+ by use BM3 , still use new Low HPFP line and HPFP line ??
"Worth than alot of more n54s"
Lmaoooo
Yes this was pre covid price hike and it seems like most n54 cars have doubled or trippled in value, but it still feels like an expensive part.
@@ZeroTo60Tube now they're worth half of a dorch pump 🤣
Hey guys i have a 2014 bmw 435i, i have FBO and a stage 2 bootmod 3 tune. I also have my stage one pure turbo coming in with diverter valve. I wanted to run full e85. Does anyone know what upgrades i will need to run full e85? Its a N55 motor.
You will need fuel uprades. You can use something like this dorch pump or PI. I would speak to who ever you are going to use for the custom tune and get their preference on which way to go. One benifit with the dorch is you can use ots tunes with BM3.
Thank you. Do you know if i would need to change both HPFP and LPFP?
@@samuelgrigoryan5463 yes
Yessssss
Inspo!
Yes James! Do a FP! More...More...MORE!
Have you any nummers for WHP with E85?
No unfortunately
Hey Mate I’ve been watching your TH-cam Channel for awhile i’m just wondering if you can help me I have a M235i I am running FBO WMI and a dorch stage 2 hpfp
I am trying to run Full E85
I purchased a Full E85 max 19Psi tune but I’ve had nothing but dramas
I saw the M2 N55 that you have been doing that inspired me to go dorch stage 2 hpfp and 100% E85
The problem that I have is the AFR seem to be quite lean and as soon I get to 4500 to 5000rpm just misfire like a lean misfire I have change spark plugs gapped 0.20” New genuine O2 sensor genuine 3.5bar n20 map sensor
I’d be curious to know what the AFR’s are on the M2 compare to mine would really appreciate it if you could help
Thanks Michael
Hey Michael. Who is doing your tune? Also what are the afrs? Just for own reference, the m2 has been going through the tuning process for over 2 months and it’s still not finished.
Zero To 60 Same tuner 2500rpm 13.8Psi 13.9 afr 3000rpm 19Psi 14.5 afr 3500rpm 19.8psi 14 afr 4000rpm 20.6psi 13.7 afr 4500rpm 19.5psi 13.4 afr 5000rpm 19.1psi 13.4 afr
I have no idea what happened there hopefully you can still read it
Those AFRs do seem normal to me. Definitely compare-able to the M2. You can run way leaner on full e85 so don't panic. One thing i would recommend getting a dragy, this way you will be able to actually compare your car to others and sort of make sure the tune is actually working and relating to a fast car. I am very closely watching the process on the M2, i'm not overly impressed at this point, but that is mainly due to customer service and very slow response times.
Another youtube channel recently reviewed this tuner and it was almost a bit of a joke, compared to what i have seen from a normal customers point of view. How have you found your experience?
How can you run full e85 with just this upgrade when the lpfp can’t keep up with full e85?
Don’t confuse your audience.
I dont know what you are on about? This car ran full e85 for over 2 years. It was faster than an OTS Stage 2 f80. Are you confusing yourself as to which LPFP a M2 has?
@@ZeroTo60Tube So you’re saying you ran full e85 with just the dorch stage 2 high pressure fuel pump, stock low pressure fuel pump?
Clarify.
@@mariomunoz7167 Yes, search this channel for M2, there are plenty of videos of it. It got switch to flex fuel about 6 months ago. But full e85 was never an issue. The f8x m cars have beefy LFPP.
Thanks god I only do brain surgery, that looks complicated
