R50/53 What’s it take for 300 hp?
A lot of money, and a good builder.
I reckon about 15k should get close. Need a new blower of course, the M45 won't get there. Everything in the block changes to prevent breakage - from crank to piston rings.
A bit of a holy grail project.
Look here, and enjoy - good luck if you try it.
Cheers,
Charlie

K20 or K24 engines from Honda.
The good ones make 200hp.
The lesser ones make anywhere from 120-170hp.
The $3150 it costs for the R53 TVS 900 kit can get you a Honda 200hp/166tq 2.4L K24A ($800), engine mounts ($500), and a freshly rebuilt transmission with a LSD ($1750) -- and you'd have $150 left over.
You could shop around and find a cheaper transmission, used mounts, etc and save even more.
The biggest problem is cutting the chassis and welding the mounts. The next biggest problem is wiring.
So, for about $5000, you could have a Kswapped Mini.
Add another $1500-$2000 and you got a naturally aspirated Kswapped Mini or add ~$3000 and have +450whp with a turbo.
BUT, you could have just as much fun with a stock HP mini and put your money into a car that will be faster.

Just like what I imagine your facebook posts would contain.
Every time I reply you can see what it takes. It's all in my sig. If someone is legit asking this question its a serious good bet an engine swap of this magnitude is beyond their skillset.
You can see below what it takes to get over 300whp with the W11 Many of the parts are Alex own design...who is Alex you ask....?
A very large chunk of the Mini community is not ver mechanically inclined. More than any other car group I have seen in the last 30 years. **** I started building and porting Rotaries at 13. Laying out the basic cost for the K swap is for people like me who do that sort of Fab work or maybe you but again Mini people still use the term stages like its a real thing from need for speed and get tunes from people calling themselves mario kart so yeah.
I have close to 15k in my engine not because its wise or the value of the car is there more so because I can I wanted to so I did. Had I had to pay someone to do all this I would not even dream of it.
Still goes without saying that if you have to ask cost you cant afford it and if you have to ask how or for tips when it comes to stuff like this you likely are in over your head. We all start somewhere though so maybe learning fab and mechanical design is where this person wants to start.

Enjoy your build Buy once. get the RMW head and Grand Am cam and a tune you will be thrilled. Most of the people here give armchair hypothetical advice and likely can't afford what they suggest. So you need to weed out who are the bench builders and who are the actual builders. You can actually lay eyes on my stuff in the MC40 thread.

alconk seems to have an interest in learning and understand how to do all these things, otherwise he likely wouldn't have asked.
Side note, I have a built Kseries swapped into a Noble M400 making 610whp that I did in my garage. So, I have gone thru the process of putting an engine in something that it didn't originally have -- as well as planning on kswapping the Mini once it's engine gives up the ghost.
I have EVERY bolt on and custom tuned and soon installing my bvh and cam. I will be porting the intake manifold and sc horns also and POSSIBLY switching from a 17% pulley to 20%..exp if i port the sc alittle.
If I can’t get 300 hp no big deal I was just asking what it would take. I’m not going to invest that kind of money for 300hp. The same money could get me in the neighborhood of 750hp from my Hemi. Like I say I have all that bolt on and just want to see where to go from there. So I just plan on camming it maybe a BVH and call it a day.
I’d honestly make sure everything on your car is working as it should and no pressing items need replacement.
Too often I see people want to make their car faster, but don’t think about their stock original clutch on their 120k mile r53.
A good supension setup with some nice tires will help you put that power down once you do the BVH and cam.
Could also be that as I get older, putting on $1000 of parts on my R53 to make sure it’s smooth and reliable is more satisfying to think of than a BVH. Lol.
