128i 0-60 time post mods

Still waiting for other manufactures to tune for the N51 DISA...cough Evolve.

Right now, AA is one of the few, but I don't know if they totally gain the benefits from what the DISA has to offer

Yeah, I don't think AA does at all.

Not sure when that will happen for Evolve. They have no real access to the N51 cars(as they are separated by an ocean), and I can see how it isn't a particularly pressing matter for them either way. N51s are a sliver of a small market.

Valid, but just isn't convincing in my book. I've offered to pay for dyno sessions on my dime and work with them to get the testing done. No dice.

Upsetting, really.


I'll probably just find someone else to do a local tune that knows BMWs and promote them.

You can get 50-70hp out of the N52 in 128i with bolt-ons and a tune(depending on choices).

Hell, with the S54 you can easily get 100hp+ with bolt ons. Same for the S85.

Last I checked on the N52, you could change the intake manifold to the one used by the 335, get a tune and a couple other bolt ons to get 20-30 HP. All for the tune of 2000 dollars.

For sound, the PE does that pretty well. For actual performance, you should do the DISA manifold swap. You will actually see real gains with it. Supposedly AA's tune makes the auto less awful as well.

Do you know if there is any appreciable difference in power/driveability between the Turner and Active Autowerke tune? The numbers look identical but AA might tune for 93 octane whereas Turner only mentions 91 octane.

Not a single part of that is correct.

FYI, i've since learned that the Turner Motorsports Performance Tune IS the Active Autowerk tune.

According to Turner, this tune will net 10 peak crank horsepower and 10 crank torque.

That's what I saw when I was searching for mods for my 328 earlier this year, was to get an intake manifold from the 335i as well as the parts to install that as well as a tune from Active Autowerke. All new parts ended up being 1493.22 when I looked. All that was supposed to get around 250HP. Unless there is some different thing to do for the N52 now, I couldn't find it after extensive googling.

Wrong.

The manifold swap is from a 330i, x3si, z3si, basically any n52 motor that makes 255+HP. It's also found on any of the n51 SULEV motors.

I bought my manifold+both DISA motors and the vent hose for $280 shipped and the tune was 600 shipped. Far off from your $2,000. The manifold and tune netted me 220 rwhp which is about 260hp at the crank. It was off a 328xi with an n51 SULEV motor.

edit: sorry if i come off like a dick, i'm just sick of misinformation being spread.

I think you meant a 330i. Not 335i. If you actually meant 335i, then you are completely wrong.

Good to know the AA tune can achieve those numbers...

Yup. Headers get you another 10-20 depending on brand, and Evolve(especially with remote tuning), should be good for even more.

N54/N55 manifold is unrelated and doesn't apply.

euro 2010 125i remap 270+ bhp.

Going to see these guys tomorrow. Very excited.

I already have the DISA manifold, my engine and ECU is same as the 130i MSV80 so just a de restriction rather than a re map.

[Solo_M_Tech]

Running the disa swap with aa tune on pss tires, my best 0-60 time is 5.4 seconds.

[x97Melbourne]

I'm kind of repeating what others have said....but yeah the automatic is slowing you down and there just isn't enough torque on the low end to do any type of launch.

I have the 328i automatic (same engine as you, but obviously heavier) and 0-60 times just aren't gonna happen. The engine/transmission combo was never meant for speed. "Our engine" is a true gem and great for cruising -- I love the car. But 0-60 times aren't our specialty.

Ah....how I miss my 135i with the MT.....now that car was fast!! :-)

lol super old thread but it's funny seeing n54 manifold swap being talked about long before any actually tried it

That's what I was thinking while reading through.

Seeing people saying it wasn't a thing back then, when it absolutely is a thing now LOL
