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!!

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

I knew I could be done, for years people underestimated this engine.

Big respect for taking on this challenge and building something different. All the best brother. Excited to see how goes and learn.

N20 gang 🫡nice video brother its nice to see someone fully building this motor

[VizualStuntzOfficial]

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.

Amazing, I'm using an N20 engine as well so looking forward to learn from you

[PartiBuoy]

Good Job man. I've replaced my N54 in my 335is myself. wasn't that big of a deal. I really like your N20.

this is nuts i had a n26 i was trying to push to 600hp but 800 is crazy on a n20

[justindaniel]

I would love to do this for my B48, wolf in sheep’s clothing 😂 GREAT job 👏 on the N20

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.

Hey there, Nice project, Keep it up! I just wanted to ask you one thing, I also have N20 and it's widely known issue that Timing chain kit is made of literal garbage plastic, Which no matters what, will definitely break down. Why no one has ever made same kit with different material? Can't it be done?

[FaderSkate]

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

[victormaholik]

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.

[edgarcamey]

Hey man, nice build I currently have a 328i and I’m trying to do the same to my car, but is there anything that can be done with cam?

[kylepalmer]

I was just thinkin bout selling my 328 😂

[performancecomptonbro]

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.

[untold_future]

Yo where did you get the bumper I'm looking for that exact one for my 328 the fitment looks really good

[hyde_official]

hey man, what did you use to make the semi closed deck? which shop helped you or when did you the parts?

[xhikuza]

Hello sir I’m trying to build my n20 as well I’m super invested what steps did you take to hit the 500whp

[cleanname]

What did you do about sleeves? Did you re apply the plasma arc coating?
