GAIN +70 WHP On Your N52 With These 5 MODS!

Today we're going to take a look at 5 of the best modifications you can apply to your BMW N52 in order to make some increased power from this naturally aspirated motor. While the N54 brother stole the spotlight from the N52, there are actually a few key upgrades you can utilize to increase its output significantly without breaking the bank.

my 06 330i n52 6spd has 212k on it rn and has not one light on the dash. truly a remarkably reliable engine, so happy seeing n52 content!

Buying an 06 N52 330i was probably one of the best car purchasing decisions i have ever made. This car just glides so well around windy roads. Always feels planted to the ground and although it seems quiet inside i have heard it from the outside driving past and it sounds great!

I have a 125i (EU Spec) in Argentina that I use as a track car. I started out with the 218hp, mapped to 130i spec, to the alleged 265/272hp Bimmerlabs maps. I have the "euro intake" and DISA valves from factory, I added a Turner Silicone Hose and BMC filter to make the intake a bit more free flowing, and then bought the MILVS kit and had Jim at Kassel Performance do a remote tune. We probably did 40/50 dyno runs, he was very helpful to get the straightest possible torque curve as there was a dip at about 3.5k. We managed 233whp without headers. That's why I said allegedly 265hp... I now have custom race headers and full exhaust as its now a dedicated track car. I'll dyno the car soon, and then play with the compression ratio by modifying the head gasket. We'll see what is pulls, but gaining 70whp reallistically isn't that easy in N52's. An ESS supercharger adds another 70whp but I don't think its worth the 5/6k plus labor costs.

There is a mod called MILV's which stands for modified intake lift valves, and it goes underneath the springs in the valvetronic to increase valve lift from 9.9mm to 11mm I believe. This means about 10 to 15 wheel hp gains. This is a pretty popular mod that goes a long way in increasing n52 power. Great video, super helpful with straightforward content 👍👍

Being able to have fun on the N52 makes me chuckle...Never knew how much I’d love our little $5, 000 e90 run around car!

A lot of people can start by making sure their 2 or 3-stage manifold actually works. Most of the time after the Disa valve get's stuck (actually oil getting into it's motor and it becomes "weak") and no longer closes which reduces power at lower RPS (because DISAs are designed to be CLOSED by default and only opening at certain RPM) and no error ever tell the owner about it. As for mods - most of european versions already have it including 3-stage and different air intake/filter so one can find used EU car/parts to retrofit it.

dude you look a little like Bradley Cooper

I run an N52 in my e86 endurance car and these upgrades with the correct tune is about 258 whp. I have tested EPIC motorsports, Activewerks and Kassel Performances tune and Kassel's was the most aggressive to get to the max number with an average delivering 255 whp, Epic's is a more conservative and better for daily driving and Activewerks was the latter delivering more power in the lower and less at the top end. If you really want to put the power down, I would suggest upgrading the differential gearing ratio to 3.73 and a light weight flywheel for maximum performance.

SoCal love brotha! Great vids and keep up the good work. I owed 3 of these rides before buying a 335i. These long ignored cars deserve some attention, and a great way to learn how to wrench on BMW’s.

[infidelrr]

Had a 2006 330i, car was amazing. With square tire setup and a m3 rear sway bar, it handled beautifully. Reminded me of a lot of my old e36 m3.

[CHVMBERS]

awesome seeing n52 content, keep up good stuff

[RearEngineShop]

N52 is such a good engine. Just sold my 08 528xi that had 293, 000 miles on it and picked up a 2011 328xi with 42, 000 miles.

[Sonicboom]

Yo thank u for going back to the n52. I got a 2006 325xi and I love it. Got some work to do on it as well so keep making more n52 content 😁

[jordangriffith]

Love seeing N52 content. I daily an 06 330i and i love it

[CoryDeanKalani]

I have made all of these mods, including transmission tuning mods. It has brought the car to life. I’m running Borla Touring Edition cat-backs that sound so good.

[walidzein]

N52 are as reliable as a Toyota, no joke, I’ve owned many n52 and they are phenomenal

[deeyomoma]

Thanks for the information but just to add to the performance is to wrap the headers so that the heat from the headers doesn’t really bother the intake manifold for more cooler air

[steifan]

Most N52's in Europe runs the three stage manifold (the 2, 5l 325i for example), so might be parts to order second hand from Europe.

[williamamaya]

Love seeing N52 content cause I’m actually trying to build my 328i E90

[Dejan_Unlimited]

My 328xi coupe after 11 years at 430.000km * Running better than ever.
I will never ever change this masterpiece for any of the brand new one *for free.
Changing Oil every 7k and ONLY - She’ll V-Power is the secret 🙏🏻
