I think a tuner has to get behind the n52 and put out effort into it for the benefit of the enthusiast/aftermarket crowd. It will be a leap of faith and a not vey profitable project given n52 being phased out and not many people buying into the new mods.

If a 130i race car in the UK can get 300whp with cams, ITB, headers and race ECU than why can we on the street get cams a cam tune and maybe an affordable strocker kit.

Seems to me this is something only a "kick stater" project and funding would solve = low demand & niche products

It would be cost prohibitive, but a 3.4 N52 would be the bee's knees.

Oddly enough, I don't really think I need more power when I am driving the car (except coming out of the toe of the boot at wgi). My car is a good bit quicker than stock from the mods that I have done, and I never find myself on the street thinking "man this car is slow."

I will however either do a secondary cat delete (cheap, more sound, very slight gain) or catless headers/retain secondary cats (pricey, a pain in the nuts, but very worthwhile torque gain where it's needed the most).

I think a lot of people are in my shoes, having a car that for a long time that is still satisfyingly fun, plus the enjoyment of keeping an old car maintained and looking/running better than many cars with 1/3 the age/miles. Plus having a car that is paid for makes doing track days and all the supporting consumables a lot more easy to deal with.

And what about the N52 that was equipped in the e90 330's and z4 3.0si's that is considerable improvement

Unfortunately every 328 is a detuned n52 variant.
With gears, a tune, and some free flow n52 is considerably more respectable at street speeds.

Well said my friend

Also true, Ive see gutted e90s for the track with headers, tune etc and they are quick as hell. Our cars are just a little heavy, but what you do you expect with a luxury German car, thats why they TT'd the 335. HP to Weight Ratio is everything

love 330i and the engine sound and handling. My focus is weight delete and power increase. BBK is ordered. I am considering cf roof (sunroof delete) and lighter seats. The car is excellent as is but there is room for improvement. Reliability is very important to me.

once you get your BBK in, would you want to sell your OEM brake calipers, carriers, etc? I'm looking to upgrade to 335/330 brakes

I honestly didn't think about it yet but it is a possibility for sure. I have two spare sets of pads also. I will let you know for sure.

Couldn't agree more-

I'm doing a budget bbk... I'm getting a set of 335i front calipers/brackets/rotors. I've never had an issue with the stock brakes on the track, but going from the 13" 330i brakes to the 14" 335i brakes will give my car a bit more repeated reliability.

Well I have 335 front calipers and ss lines. Once you get to intermediate-advanced level the oem 335 brakes become a weak point as they heat up and it becomes harder and harder to modulate them deeper into corners. The rear calipers are weak also. It is a great set-up for street and spirited driving and ok for track as you will need to learn their braking response when hot and cold. I figured if I use BBK over next 3-5 years or longer it is definitely worth it. Hope this helps.

I'd love a legit bbk, but at my skill level, I just can't justify that kind of $$. I'm hoping the 335i fronts and track pads keep up with Hankook Rs3 tires that I'm planning on getting. In a couple years I will most likely be tracking a Corvette.

Sorry that I am reviving an old thread here,

The shittiest part of the N52 is pretty much mod-ability. The block is apparently weak to to make any power that will come close to a slightly modded N54. But thats also because its N/A, its harder to make power. Regardless, slapping a turbo on a N52 is more hesitating than slapping a turbo on a M5X motor.

But for a daily or something, i feel like its a pretty damn good engine. For me, I got a 525xi, my N52 only has like 215hp and 186 lb/torque if you look at the specs. I want to mod it a little bit but i am stuck in this position where i either mod my 5 or I just try to find a project car (E30 or maybe a 1970s Datsun 240/260/280 or something with a v8)

HP per dollar will never win out with N/A, but the N52 does have decent aftermarket support. Just be realistic about your goals and mod from there.

True enough. The block isn't the big problem if FI isn't retrofitted, it's the pistons, rings, etc. at least in theory. But custom pistons, rods, etc. can be had from Carillo and head work is doable, albeit expensive as are cams. Didn't you link to a 385hp N52 one time?

Yeah, a guy on this forum 'Bigbird' I think. N/A can do it, just how deep are your pockets?

Gotta dig it up, thanks. Yeah, the cost is stoopid expensive. Cheaper to get a race built S54.

I was thinking about the Stage 3 Intake and the Euro Air intake box, but im not sure if that will fit in in the 5 series engine bay. Im assuming the E90 and E60 bays are very similar. But idk, no one lists anywhere that it will fit a E60.

The Euro intake box is a waste of money, and I don't think it will fit the E60 chassis.
