So, the E90 325i and the 330i are very similar.

I imagine that Dinan will do something with the ECU, the intake, the suspension, the wheels, etc. So, what will be the point of someone getting a 330i if they were planning to make their car a Dinan 3?

[HRC]

The Dinan e90 330i will be more powerful than the Dinan e90 325i. I don't really understand the question. All of us e90 330i owners must be stupid, we should've just gotten a Dinan e90 325i and put the stock 330i to shame.

uhh wt is DInan?

[roburado]

I guess the point of the question is that the 325 engine is a de-tuned 330 engine. If Dinan is going to upgrade the 325 engine, with a new intake, ECU, strapping on a new exhaust, etc. What will be the difference?

[BellasBmw]

How does Dinan work? I went to their website and i didnt really understand it. When/IF they come up with products for the 325 E90, im hoping someone on here will give me advice on it.

I can see your logic here, Robur - if the 330i's "added engine components" are to be supplanted with Dinan performance parts, then it makes no sense to get the 330i over the 325i if you do intend on getting your car DINAN'd. In fact, that would mean that a 330i owner who intends to DINAN his/her car would have squandered money relative to someone else who purchased the 325i.

Obviously there are still differences, i.e. the 330i purportedly has bigger brakes, the Logic7 sound system, bigger (and better looking) sports wheels, among other smaller things so even so, a DINAN 330i doesn't mean a waste of money.

EDIT: The DINAN Z4 on the latest Roundel was not even impressive. Better looking wheels, and only what...13 more horsepower from the DINAN intake? Psh...

Well, you can go to Dinan dealers (often times, BMW dealers that sell Dinan parts) and they can put them on for you. At least, that's how I understand it. Then, they match the factory warranty. You can upgrade as much as or as little as you want with things like the exhaust, engine software, suspension, wheels, transmission software, etc. Those different levels are the "stages" that they talk about. Did that help, Bella?

But you could probably get Dinan brake upgrades too, right? One could also get the Logic7 as an option. If one only wants one set of wheels, and the Dinan ones are fine, well...why bother with the Style 162s or whatever? Why not just the base 325 wheels if you're going to change them anyway?

By the time your done with your Dinan 325i, you could have purchased a 330i, but then again, why would anyone want to do that?

You've started to add up the $$$...big time.
Brakes, wheels, etc...you're looking at almost as much as it would have cost for the 330 in the first place.

Like Squawks said, the Z4 was upgraded by Dinan and only added 13 hp. And that's the older 3.0 liter engine....with the new one its going to be even tougher for them to up the power. I'm sure they'll find a way, but it ain't gonna be cheap to reach 330 levels of hp.

I noticed that one of their ugrades for the E46 was a High Flow throttle body to supplement the hp gains from the intake & exhaust: $500 plus installation charges...OUCH!

Any of these products out yet for the e90?

Nope. They said it would take about a year....this was about 5 months ago. Might not even be the same stuff that they used on the E46..who knows?

I'm not talking about Dinan-izing a 325 to avoid gettting a 330. I mean, if one were going to Dinan-ize a 330, why not just get the 325 and upgrade that? I suppose it would depend on what they'll have available.

[Thumpzilla]

If there is one thing I have learned on my Motorcycles/cars

MODS = $$$ & Problems.

It's like those Rice Rocket racers that buy an Accord and put 15k into the motor and buy a loud exhaust system. Or someone who puts 10k dubs so people don't look at their 1995 explorer. With all that money you could of bought the next level in the food chain.

Maybe I'm getting old, but to take a chance on voiding the warranty on a 40k+ car does seem like a smart move.

I am picking up my 330xi tomorrow, hopefully it will do.

Because Dinan might charge an arm and a leg just to upgrade to a 3 stage intake and ECU remap just to get the 325i's motor to perform up to the point of a 330i. It might even be as much as it cost to get a 330i. So why would you want to do that modification with an aftermarket company (no matter how good and how much warranty they provide) when you can get it "modified" from the factory.

[BMRAMA]

If the previous 3 series can be used as a guide, they will have a $3000 kit which replaces air intake and exhaust, springs, software, add front and rear braces, and floor mats. (+6k for a brake change.)

I think spending 5k after a year or two to get a different level of performance is well worth it. While a 330i might not see a tremendous difference, a 325i should see a 40+ hp gain.

What I like most, is I feel I can trust Dinan. They're established, and they do serious work.

When they do a signature series conversion, I'll be there.

I was hoping that someone caught the not-so-subtle point that the 330i is not just a chipped version of the 325. The multistage intake present on the 330 and not on the 325 would cost serious $$$ aftermarket to add onto the 325. Your point is right on.

Right...but if the 330i will have an intake upgrade too, wouldn't they do the same kind of upgrade on the 325i? See what I mean? I guess it depends how different the 330 and 325 intakes are and what Dinan will do to them.

Personally, I'm on-the-fence re: modifying cars. Generally, I'm not big on the idea. I'm generally wary about modifying things. I generally feel safest leaving things as stock as possible for as long as possible. I'm probably just going to get a 335i, 335Ci, or one of the rumored M3 variants. But yeah...the thought crossed my mind to Dinan-ize a car.

But point taken

[mapezzul]

Everyone needs to stop and take a breath..... just think about how much an intake really adds to the car... 10 hp & pounds of tourque, the 3 stage is just so the power band is across all RPM ranges, it moves when it gets to a certain point so that range gets the correct air flow distance, VW/audi has done this for years as a 2 stage since most people do not rev the engine to its limits, thus the reason power dropped off at the higher RPMS.
So the rest of the HP is from what you ask 3-5 Hp from the larger exhaust. The rest is in the software, So will Dinan or someone do some reprogramming you bet. There is no other explanation, the engine block, pistons, cams and the like are the same.
Dinan would come with a warranty so there is no worry with that! By the time that kit comes out, the engines may already have changed to direct injection, which will boost the HP and efficiency even more!

[loihisteve]

I doubt Dinan will offer an attractively priced solution for the 330i N52, simply because BMW has already max'd-out the perf for that engine ... for the 325i N52, its a completely different story, and I consider it to be BMW's gift to the tuner world.

For the 325i N52, I believe Dinan will offer solutions with multiple levels of perf, with a first-level upgrade that keeps the single-stage Intake Manifold, and increases the lift, duration and overlap of the cam-profile just slighlty (my best guess is that they can achive a 15-hp and 15 lb-feet torque gain, with 0.10" lift, 10-degree duration, and ~3-degree overlap increases) ... and that this first-level upgrade will cost no more than $500-$700.

If one uses the latest Car & Driver test of the 325i as a baseline (0-60 in 6.1 seconds), then the first-level Dinan upgrade should achieve a "consistent" sub-6-second 0-60 time!
