Final Assembly and First Start of my 800HP+ Capable BMW N20 Engine

- It's been about 2 months since I started this project, it took a little longer than I wanted because of parts and time away from work but I finally finished the assembly of our forged and decked BMW N20 Engine. We had to modify the block quite a bit adding hardened aluminum rods in the water jackets and notching the lower cylinder walls to fit our forged rods. I did all of the work myself in my shop at home!
The forged rods and pistons along with the decking and ARP studs should allow us to push around 800 safely although I don't think we will ever get that high. We have some supporting mods but need to get bigger injectors and upgraded fuel pumps and of course a larger turbo and a tune but we are halfway there!
Hopefully we get a smooth first start and the engine stays together!! - ยานยนต์และพาหนะ

Hey All, I just got the website launched with all of my build info. I will update it along the way with any new stuff I add. I also have all of my turbo piping on order, going to try to frankenstein some things together to make it work without spending 3k on a custom setup. www.projectrandom.com
Post this on your community tab bro 🤝

I knew I could be done, for years people underestimated this engine.
Haha, I see people all over forums hating on the N20
@@projectrandomCO im that guy still hating on this engine but congrats on you for taking on this challenge
@@hydarail6477 haha thanks man. Almost done with the turbo setup, should have a first start soon!
True like people forget bmw already had a 4 banger that made huge power 😂
800 hp n20 is mad
Big respect for taking on this challenge and building something different. All the best brother. Excited to see how goes and learn.
Take my 328i now TAKE IT!
I'm fully intune for this build
great contents! wish to see more...
Good Job man. I've replaced my N54 in my 335is myself. wasn't that big of a deal. I really like your N20.
You are a beast!
I would love to do this for my B48, wolf in sheep’s clothing 😂 GREAT job 👏 on the N20
Go for it!! The 48 has better bones to build on.
awesome
Subscribed great content,..
Open deck 4 cylinder had to have been a pretty penny spent, props to you guys for making it work. Always love seeing underrated bmw motors get the work that they deserve done.
Hey, I did everything myself for under 900 bucks. Forged rods and pistons and the decking/block modification. Working on the turbo kit now, just pulled the head again to put an Athena cut ring gasket and make sure everything looks good for more boost!
@projectrandomCO where are you located
@@Trinibad718 Colorado Springs
@projectrandomCO good shit fam 👏
@@projectrandomCOthat’s crazy. Do you know if there are reputable dowel pins that would fit the n55?
this is nuts i had a n26 i was trying to push to 600hp but 800 is crazy on a n20
I probably won't get close to 8 unless I dump some serious parts into this thing. I'm looking closer to 500 for reliability. Maybe 6, the pistons are slightly higher compression than stock and there have been some nice aftermarket parts released for the N20 to help make reliable power. The b58 fueling and larger bolt on turbos with the current head set up will get mid 500's pretty easy with what's already on the car. There are a few companies that make upgraded ZF transmissions up to 1500 hp/1200 tq. That will be a must past 450-500.
I wanted to build my motor but it seems cheaper to buy another car this is interesting to watch would love to see results! I have yet to see a fast n20 besides like 3 of em I know of via the internet this looks like it’ll be #4 lol
same it seems way to expensive for the amount of power you get but this guy seems to be doing it cheaper i want more info
I am hoping to get some decent numbers out of this thing lol. I didn't know anything about the lack of aftermarket support but that made me push more. So far as the car sits I have about 5k invested. I picked it up for $2900 with the blown motor and obviously did the work myself. The expensive stuff is going to be the turbo and custom piping. I am going to try and make a manifold myself but who knows how that will turn out haha.
I am in the process of building my website with the info on the build so far. If you have any specific questions let me know, contact info is in my profile. I have everything priced out and with the price of the car included I will hopefully only have an 8k investment, another 5 or so for a transmission if I decide to push it past 500hp
Fbo, n20 228i, e30, 4.3 0-60, and that's with bald run flats LOL. $3k in mods. N20 is slept on, and it's super affordable.
Definitely, I have had a lot of cars and this is one of my favorites for sure. Just with the motor built and FBO I can feel the potential, from the dig this thing is crazy. My turbo is definitely going out though, the spool time and throttle response is getting worse every day.
@@projectrandomCO Same
hey man, what did you use to make the semi closed deck? which shop helped you or when did you the parts?
Hey, I did everything myself, I have a detailed write up on my website under the projects tab. www.projectrandom.com
Yo where did you get the bumper I'm looking for that exact one for my 328 the fitment looks really good
Hey, the bumper came worth the car when I got it from auction. I'm not sure where they got it, sorry. It's the m3 bumper, that's about all I know, It does have really good fitment though.
What did you do about sleeves? Did you re apply the plasma arc coating?
Coating was in great condition so I left it. Going to run it as is for now. Eventually, I want to pick up another block and head to darton sleeve and mill for bigger valves
Pro tip - get the red push start button. Automatic +50hp
curious what ur gonna do about the timing chain even though its not technically the old guides
Hey, not sure what you mean. Everything was replaced and upgraded to the laser etched gears to hold it in time under a higher load.
Welp you motivated me to build a motor for my 428 I’m already FBO with a stage 2 tune but I’d love to be able to get 400whp
What do you have for mods so far? I need to get a larger front mount and a turbo asap. Pretty sure my wastegate is leaking, power after 3-4k drops off drastically and when I was putting everything back together, I noticed my flap was super loose.
@@projectrandomCO A larger front mount for sure look into the stage 2 for your setup. Stick with the electronic waste gate. I have a VRSF front mount, a VRSF down pipe, Active Autowerke charge pipe, a MST turbo inlet and a GFB diverter valve, and a Injen cold air intake
same i have a 15 320i fbo stage 2 this is making me wanna build a engine i just dk where to start
@sl0wf.30 If you have all the parts and some time, you can get it all done in a weekend or two! More than happy to help answer any questions. This was my first BMW build, and I have to say the engine was super easy.
@@projectrandomCO i’ll def be reaching out to you. i’ve been debating on buying a m or rebuilding the engine and i think that’s the route i’m gonna go. is there any way i can pm you?
Euro shops been doing this build for awhile.. there’s a reason it’s not more prevalent. B48… I own a n20 powered bmw. Half of a n54. Same issues as n54 and then some.
So far the build has been solid, just did my first start and buttoned up a few things. With the motor built and proper maintenance and tune, I can keep it in the safe zone for sure. I haven't seen a custom build yet just a lot of bolt ons and remanufactured turbos. If you know of a custom built N20 I'd like to check it out!
great build man ,i have a n20 myself what piston and rods are you running ?
Soo I was holding onto this in case I ran into problems, but I have about 2k miles on everything now, and I am really happy with the piston and rod setup. They are CP Carrillo clones from China and were probably one of the best quality clones I have ever used in a project for a fraction of the price. The balance of the pistons and rods were less than a gram apart and I got them in less than 10 days. Shoot me an email and I'll send you all the details if you are looking to get a set.
Link to piston/rods please
@@franciscobotello4381 Just published my site, has all of the info in the project section with links to everything. Let me know if you have any questions.
Where’d you buy the new timing chain and guides at??
FCP Euro sells everything
I need to steal your recipe…
It's all on the website. www.projectrandom.com
Do you think this could be done on a 2.0 Giulia. The engine is forged from factory.
Yo, the problem I ran into was no one made decking for the N20, you could do it in most engines where the water jackets run around the cylinder walls. If you know how to build an engine and are mechanically inclined you could do it no problem. I don't know a machine shop that would guarantee that kind of work though.
Hey what up bro where did you buy you’re piston I think imma go ahead and tackle the job myself.look at my cylinder with a bore scope and they look good so you’re saying if everything looks good in the cylinder block, just replacing piston with rings and that will solve the issue. No honing involved.
Hey, The pistons and rods are on my site under the project section. They come as a pair though, if you want stock pistons and rods I have 3 that are good. The ones I bought require block modification, you have to cut out a decent amount at the bottom to fit the H beam rods.
@@projectrandomCO k my engine stock I guess I’m trying to get information if my Pistons are OK can I just install new rings on them and install them back? No honing required I just want to get the car back on the rod it’s my mother-in-law, car just want to help her out or is it worth fixing these cars or what do you think?
@@820performancecomptonbro4 You might have to just pull them to see, it could be the ringlands for the rings that cracked or the rings themselves, no way to really know without breaking it down. But no honing required if the walls look good. Def worth fixing, the F30 holds value well. If you go with stock pistons and rods with new bearings you are only in like 600 bucks with your own labor.
@@projectrandomCO k cool I really appreciate you bro thank you for you’re time I’m not really familiar with this model mine is a 2015 528i is it a f30 the model ?
What’s the reliability on these things? What made you choose this platform to build? (no shade, I’ve just never owned a BMW without a straight 6)
Hey, stock the pistons are weak but the crank is forged and the head is good. I bought this with a blown motor for a really good price, never owned a BMW before this. With the block built I can safely daily 600hp but the transmission is weak so that will need an upgrade at some point. I do want a 135 to build sometime but need to finish this one. I have the whole thing together I just need to rebuild the turbo manifold and finish my tune.
@@projectrandomCO Thanks for the reply, I’m not really mechanically inclined like that…lol I’m driving a full bolt on N55. With a tune 417/512 to the wheels on an E85 blend. But it’s a Lego set, I’m not doing any real work…I bolted some shit on, catless DP straight pipe and bm3 Stage 2+…the fact that people have skills to just take their shit apart and build it is wild to me, that shit is sorcery. 😂 Good luck man, I’m invested in your build now…lol I wanna see this shit succeed! 🤙🏾
Thanks man, I appreciate it. Hopefully I can get some more content out soon.
I have a N20 too do you have a shop in miami Florida
Hey, no I don't have a Shop, I'm up in Colorado
this is really cool, im trying to achieve something similar with a b48 gen 1, can anyone here confirm that is just the pistons that where cast, im pretty sure the rods and crankshaft are forged, i have the higher compression b48 11.0:1, essentially the b58 just 2 less cylinders, even has the same HP50 transmission.
The B58s are able to hold insane power stock, if the 48 is the same setup I think you should be good with quite a bit of power before you run into any issues. I am not sure if they are cast or forged but I am pretty sure one is cast and one is forged just not sure which is which rods or piston.
Are those blocks decked from the factory? Once I get this car where I want it I am definitely looking into getting a b48 or b58 car, I am really loving the BMW platform! Also there are a few different companies that make bulletproof hp45-95 transmissions up to like 1500 HP.
@@projectrandomCO Hi again, yea so after some more research, i literally have the b58 block same compression etc , difference being cast piston heads instead of forged, so same forged rods and camshaft (reduced length of course)
Yea there really good engines man, and yup b58 and b48 all closed deck, i think new forged pistons, better intake manifold, and a better turbo 400hp easy, check out vehicular DIY channel, hes doing cool b48 stuff
Yea transmissions are amazing, both B engines use same HP50 gearboxes, mad is 660nm torque, enhanced transmission csn take 1000nm
@@Reaper_f30 Awesome, I say go for it, if you have some mechanical aptitude it's not difficult to rebuild these, I was surprised at how easy everything was once I got the engine out of the car. I just got an Evo2 intercooler and have my fueling for full e85 on the way. Last thing is a big turbo to see how far I can push this thing. I would love to sit around 500-600 reliably, I think with a big enough turbo I can make some real power on lower boost, the challenge is finding that sweet spot for fast spool but enough flow to keep temps down at a higher RPM. I wouldn't want to push much past 35psi on the current setup, i'll need some head work and those 4 corner 10mm bolts switched out to ARPs. Only other thing is the trans, that is probably going to grenade at that power haha.
@@projectrandomCO thanks man i think id get it done at a shop but ive done all other mods myself 😁 another great thing about the b48 and b58 is the intercooler, air to water so no real need for a aftermarket front mount unless your tracking it or pushing hard alot in the same outing
@sanjeevcrazydude96 keep us in the loop man, would love to see everyone's builds.
I was just thinkin bout selling my 328 😂
Hah, I have had a lot of cars, foreign and domestic (Audi, Mercedes, Mustangs and Camaros) and the BMW is one of my fav. I was an Audi guy through and through but I love the sporty feel of the BMW, it's on the top of my list for sure.
Where did you get the engine built
Brother, this video is literally me building the engine in my garage...
Hey what up buddy I have a 2015 bmw n20 engine I have low compression on cylinder 1-4 can this engine can be gone like a regular engine ?
Hey, honed? If so, no, there is a really thin plating on the cylinder wall. if you hone it, it will ruin the cylinder walls. Low compression could be rings or damages pistons or possibly slipped timing a tiny bit. What's the compression in each and is it running or not at all?
@@projectrandomCO 1-3-4 cylinder 90 psi number 2 119 psi car doesn’t want to start I added oil on each cylinder and it bumped up to 160 psi so I’m thinking rings car only have 95 k miles
@820performancecomptonbro4 definitely the rings, you can try soaking them in berrymans b12, if it's just oil and crap stuck on the rings that will get it cleaned off, otherwise you'll have to crack it open and get some new rings/pistons
@@projectrandomCO where can I buy Berryman b12 and if that doesn’t work where do you recommend me buying the Pistons and rings from?
@820performancecomptonbro4 should be able to pick it up at the auto parts store, it's valve cleaner sort of like seafoam but a little more potent. Pour it down each cylinder and let it sit and add more every few hours. You'll need an oil change after since it will leak past the rings and get in the oil. If it doesn't improve at all you probably have a few broken pistons. I have 3 oem ones in good shape, 100k miles on them but normal wear. My number 4 blew up though. Otherwise you can pick them up anywhere online.
800 hp?????? Omg!!!
How in the heck are you pushing 800 HP on that weak lil engine? I mean huge respect but my engine is already dying on almost stock
I fully built the motor and have all the supporting mods and a big turbo. I won't be pushing 800 anytime soon though I need to upgrade the drive train first.
Big respect man, I am going to change the timing chain soon on my N20B20. Hopefully it will fix my misfire@@projectrandomCO
