Hello Family.

I had a quick question regarding possible gains. I’m looking to get 300hp at wheels on my 2011 328i if my hopes are correct would i be able to achieve this with the following mods:

-BMW PE
-BMW PI
-3-Stage Intake Manifold
-BMS Power Box
-A proper Tune.

Would i hit 300hp at the Wheels? or am i just way off? What do yall recommend.

Dude you're a hilarious!!!


No seriously we love your sense of humor.




300hp at the crank on a 328= not happening
300hp at the wheels= unless your car is being fueled by the blood of Satan himself, it is NOT gonna happen.

power box gains are minimal and not needed if you have the tune.. the tune plus those mods will put you at maybe 250-260hp at the crank(and that's me generously speculating). I know because I had that setup; except I had a BMW Euroinatke instead of the PI
If you added headers to that setup that would net you some extra HP but still no where near 300hp range

Pretty well put. Get some cosmetics for it or sell it and get a 335. There's no secret thing that will get you power on these. A tune, PE, PI may get you 10 hp on a 328. All for what? $2500?

Just be happy with what you have unless you want to spend stupid money for throttle mapping and better exhaust note. Your best bet may be the 3 stage manifold, but I don't know much about gains since I have it on my 330.

Trust me, I've trolled evey thread in here to find some hidden thing for n52 gains. There are a couple guys with close to your numbers but they paid for it. More than a down payment and depreciation hit to buy a 335 and JB4. Be happy with what you have put some wheels on it, cosmetic stuff. That's your best bet

3 stg intake, light weight wheels, tune, headers ... after this it's all about weight delete

You still won't put down 300 at the crank let alone at the wheels.

[BeachsideF30]

300 at the wheels

N54 engine swap. No, seriously. Check ebay, they aren't bad plus it would be a cool project to post about and you could sell your engine to cover part of the cost.

would also need a ZF tranny from an N54. The GM tranny is not set for that kind of torque and hp. Would probably also need the ECU from a N54 motor. The whole project would be an expensive cluster fuck. Would be way cheaper and easier to trade in.

haha i knew i was gonna get shit on so how come all the threats here state the 3-stage intake mani mod will put me at 260 to 265? i figure maybe 15 or so for PI and PE plus the self claimmed 10hp from BMS and some magic tune to push me the rest.

PE list a massive gain of 6hp at like 6000 RPM
PI list like 2 or 3hp (not 100% sure on that one)
This was right from the BMWUSA site

Your math is a bit off.. You MIGHT be at around 250-260hp WITH a tune, 3-stage intake manifold, PE, and PI. The BMS will do nothing when ran with a tune, in fact it should be uninstalled at that point.

don't invest the money, it is much better off used as down payment on a 335i

If you do all the work yourself it wouldn't be terrible. Certainly easier but not necessarily cheaper to trade depending on mileage etc. I've been able to clone DMEs, sync with CAS and do other coding and programming so not worried about that and used trannies are around as well. More of a project for an experienced person, not to hand everything to the shop and say "here ya go, swap my engine" and give them a blank check. That would be costly.

well fak!! i guess ill stick with just a 3-stage intake mani and some cosmetic retrofits....i cant get a 335i because my insurance would go up from 110.00 on my current 328i to 250.00 on the 335i......(yes my record is not the best way too many speeding tickets and a few totals )

PS: would yall recomend a 3-stage Intake Manifold and a BMS Power Box?

the manifold is useless without a tune and the BMS is NOT a tune
get an AA tune if you want to go that route

[Volasko]

Lets put it this way, I have a 330i so I already have the 3stage IM, I have the PE, scoops, AA Tune, Carbon filter delete with K&N drop in and the best I could do at the wheels was about 215HP (see this for detail: http://www.e90post.com/forums/showthread.php?t=654633). If you really want to make your car as fast as possible do this:

- 3 stg IM
- Catless headers
- AA Tune
- Lightweight wheels
- Diff swap with a higher ratio

Then as others have mentioned start ripping out parts to save weight.

stay away from bms and get a tune with 3 stg im and apex arc 8

[GTKrockeTT]

as others as said, no way you're sniffing 300hp at the wheels unless you go FI, and that just isn't a cheap or reliable option for the N52. that said, i'm happy where i'm at performance wise. would love to have the N54 or even N55, but first preference is for a wagon.

[Casca]

Wonder if the N53 cylinder head would fit an n52. I think the n53 makes 275hp stock and can be tuned close to 300hp.

You should buy a good (expensive) radar detector and a good (expensive) laser jammer then instead of all of these parts and repair your driving record. There's no point in horsepower without the ability to use it. I recently bought a 335i and made the mistake of not swapping my blinder LJ from my 330xi and went for a drive through GA. Caught going 92 in a 70 by Turner Co SO with a damn laser. $650 later I'm hitting myself in the head for not just buying a brand new blinder to put on the 335. Wrong thread perhaps but my 2c. Protection first, then power.

Probably but the N53 was never released in the US so there is no way he can get one locally. He would have to have one shipped over from Europe and then installed; again it's not worth the cost.

ebayUK. I didn't see an n53 head, possibly I am searching wrong and not sure what I am looking at, but cylinder heads off other 2006 and new cars were anywhere from $300 to $800+ US and the shipping wasn't too bad.

Not that I would do it. I have had enough. I mean, I am sure it would not be just the head. You would then need the direct injection parts as well. And god knows what else to make it work with the ECU

You would need the whole damn engine.. It is as different from the N52 as the N54.
