Send me a link! This is intresting...

no there is no SC for the 325/330 yet...

How is this poject going? Something new?

how hard is it to crack the bmw ecu..? I guess this project died?... All i want is the 260 hp from the z4..lol

Turnermotorsports converts the 325 to 330 and gets 262hp.

I take it you read through the ENTIRE post... Poor bastard...

I too am amazed that this has gone on this long with no one validating whether or not it worked....

[Driv3r]

omg, its back from the dead......i remember this thread, it kept me up at night for 6 months straight!

[Not Ur Avg 3]

haha soo many dreams shattered
dont worry guys, im close to gathering all the parts my self
and getting just a REFLASH accounting for all the mods in their mapping (TMS), but $$$ is killing me. hopefully before summer is my goal.
if someone else can jump on this, plz do

DISA actuator motor



(1) DISA actuator motor
(2) Throttle valve

The actuator forms a unit with the drive. The actuator is driven by an electric motor and gearing. The control electronics are integrated in the DISA actuator motor. The DME controls the DISA actuator motor by means of a pulse-modulated signal. There are only 2 possible positions. The actuator can be closed or opened. When activated, the actuator moves the flap to each end position. Depending on the engine concerned, the N52 is fitted with 2 DISA actuator motors, or 1 DISA actuator motor, or without.

How it works
The power and dynamics of an engine depend heavily on the quality of the cylinder filling. The intake air mass oscillates due to the piston motion. These oscillations are overlapped in turn by oscillations from pressure peaks. To guarantee optimum air intake, the N52 engine has a three-stage differentiated air intake system (DISA).

The air intake guide is realized by a switchover mechanism in the inlet pipe with two DISA actuator motors and an overshoot pipe in the intake area. The DISA actuator motors are each driven by an electric motor. The two DISA actuator motors are of different sizes. DISA actuator motor 2 is fitted in the overshoot pipe and DISA actuator motor 1 is fitted in the collector for intake air in front of the resonating pipe.



1st stage - idling/lower engine speed range
At idle speed and in the lower engine speed range, the DISA actuator motors 1 and 2 are closed.
The intake air flows past the throttle valve into the resonance pipe. In the resonance pipe, the intake air mass splits. The air is fed via the collector pipe and resonating pipes into the individual cylinders. In this way, three cylinders are provided with a comparably high air mass.



2nd stage - medium engine speed range
In the medium engine speed range, DISA actuator motor 2 is opened.
In this case, it is assumed that the inlet valves of the first cylinder are just closing. The gas motion creates a pressure peak at the closing inlet valves. This pressure peak is passed on via the resonating and collector pipes to the in next cylinder in the firing order. This improves the filling of the next cylinder to be charged.



3rd stage - upper engine speed range
In the upper engine speed range, both DISA actuator motors are opened.
In this case, it is assumed that the inlet valves of the first cylinder are just closing. The gas motion creates a pressure peak in front of the closing inlet valves. The intake air mass is now fed via the resonating, overshoot and collector pipes.

EDIT: The firing order of the N52B30M1 engine is 1-5-3-6-2-4

2006 330i e90 n52 B 3.0 right?

Exactly--specifically the N52 330i.

Yar... I suppose it was worth it for the nuggets of good info sprinkled throughout but...painful none-the-less...

Don't you wish you could get back the last 3 hours of your life that was spent reading through all 26 pages?

lol i rmr i was really close to completing this project... haha
good thing i spent the money elsewhere, got to do so many other mods... o well

With the depreciation of old technology, the sum of the parts of such a mod easily exceeds the value of doing an upgrade. It would be cheaper to trade up your vehicle.

100% agree... I can't see spending that much on the entire kit, when I could pick up a new 335i for $50/month more than my current payment.

isnt this basically what this thread is all about?
i was thinking about saving up for this. any opinions?

Yes Will, that's been up for awhile. That's a lot of money to spend on a car that you know can be purchased with the N54. Maybe save up for a 335i trade?

[BMW_E90]

sorry noob question... how much would be a 335i trade be from a 325i with about 27,000 miles

[Willstophe]

I'm almost finished with it. I'll post images as I go along. My manifold is down at Sterling BMW Parts Department in Newport Beach and they ordered every possible bolt plus the other actuator that I'm missing. I also ordered a brand new 330i ECU direct from Tischer parts and I'm going to get a refund on my software by DTE. The parts should be in by this Thursday. Active Autowerks in Huntington Beach is doing my install.

[Willstophe]

They also ordered the wires that connect the actuator's to the ECU.

[voltron1011]

Awesome Will!
You may want to start a new thread that covers it all. If not, I'm not sure how many people will actually see buried in this one.
