This.

or headers +tune
Or both if you have deep pockets

Sell 128 + buy used 135.

Don't forget to have the headers coated and wrapped, it matters.

And have a thinwall 304 stainless catback fabricated with a Coast Fabrication muffler.

Don't forget a free flow intake.

But all of this still isn't enough really.

Or this. It is cheaper in the end...

[bazil769]

No more sell my 128i i will not sell it for a 135i if i wanted a 135i i would have bought one.

[bazil769]

That was a joke... Really.

I would've bought an M3 instead of spending way more than a new one on modifying a 328 but it wouldn't have been nearly as much fun.

Wait, what? Gain 100rwhp?! Not with an N52. Unless it's completely rebuilt as a race engine that won't be street legal or streetable.

Um, ping Andrew at Active Autowerke. You're welcome.

Bms power box is rated well at 10+ hp or so and many said if you have an AFE or similar grade intake it can be considerably more. also gets rid of the throttle lag, which is probably even more noticeable.

I got one super cheap but haven't installed it yet. Someone had one on eBay for like $200 i believe.

Don't do this. The BMS is a terrible tune that you can mimic by, quoting @ST|G here "Stepping on your gas pedal more"

3 Stage manifold and tune is going to be the best bang for buck out there + headers beyond that. Intake and exhaust will gain, but it will be minor for the cost.

I've only heard good things about it. I have n51 so my options are limited

[631twentyeighteye]

A tune is the best thing you can get for an n51. Not the powerbox. That only makes a positive difference on automatics IMO. It helps fix a bit of the sloshy feeling in D.

Lol i do have an auto... It's my gf's DD so i'm limited. I looked into the manifold option, but not an option for me. I got it for $150, so probably worth it.

No it's not. Save that money and buy a tune or buy the manifold. Trust us.

have you looked into the bms powerbox? Overall, it's gotten great reviews other than the singular one you referenced. 10-15 dyno proven HP added for $150 not worth it, especially considering the easy install?

Also, please tell me how I can do the manifold swap on my n51.

n51 doesn't require a manifold swap. All you need is a tune and you will gain the benefits of the manifold.

N51 comes with 3 stage manifold already installed from the factory.

Ignoring the rude, and ill-informed comments from before - the powerbox isn't adding 15whp on any car. We have the dynos to prove it.

If you still want to waste your money on it, great, but don't say that we didn't provide you with the information to make a good decision.

(Thanks for adding in the part about the 3 stage for me)

There isn't a lot you can do to increase the power substantially on the 128. Even if you could get 10 or15 hp that is a small increase and likely not very noticeable. I have an e90 330 and went through the same search you are looking at now. I ended up putting in an lsd with a higher gear ratio and a bmwp exhaust and intake and called it done. Also tweaked the suspension which helped it go faster at the track.

Depending how much you want to bolt on and the amount of money you want to spend you can get ~35rwhp which makes a substantial difference with a manual trans and a Salisbury type LSD with a final ratio that makes sixth the one-to-one gear. Definitely worth the money to modify the suspension and driveline, no question. Not exactly cost effective to squeeze out another twenty hp though.

Unfortunately the 128 like my 330 has a relatively low roi on most mods that are go fast targeted. Not trying to rain on the party just calling it how I see it.
