Frequently Asked Questions (FAQ) About the BMW E46 330 ZHP Performance Package Option

[Marcus-SanDiego]

Question: When did the BMW 330 ZHP first debut?
Answer: The BMW 330 ZHP, which was created by BMW Individual (a division of BMW’s M performance division), debuted at the Los Angeles International auto show on January 2, 2003. Production was scheduled for March with the first ZHP-equipped 330s hitting showrooms in April.

Question: What transmissions were available for the BMW 330 ZHP?
Answer: The 2003 model was only available in a 6-speed (Getrag) manual transmission (GS6-37BZ, part number 23007532498). From 2004 to 2006, the ZHP was available in a 6-speed manual transmission and automatic transmission.


Question: Was the ZHP ever available in SMG?
Answer: No. We've discussed that issue here (http://www.zhpmafia.com/forums/showthread.php?1104-BMW-330-ZHP-w-SMG) and here (http://www.zhpmafia.com/forums/showthread.php?2494-ZHP-with-SMG).


Question: Was the BMW 330 ZHP available outside of the E46 platform?
Answer: No. The 330 ZHP was only available for the E46. It was not available, for example, on the E90 330, which debuted during the summer of 2005.


Question: What is the ZHP's horsepower?
Answer: It is 235 HP at 5900 RPM, which is 10 HP more than the standard BMW 330.


Question: What about torque?
Answer: The ZHP puts down 222 lb-ft of torque at 3500 RPM, which is 8 lb-ft torque more than the standard BMW E46 330.


Question: What is the redline for the BMW ZHP?
Answer: It is 6800 RPM, which is 300 RPM more than the standard BMW E46 330.

Question: During what years were the BMW 330 ZHPs available?
Answer: The ZHP performance package was available from 2003 to 2006. The sedan was available during the model years of 2003 through 2005. The coupes and convertibles, meanwhile, were available during 2004 through 2006. The last ZHP rolled off the assembly line in August 2006.


Question: How many BMW ZHP Performance Packages were ordered/produced?
Answer: While BMW has never published that information, SickFinga endeavored to laboriously go through each E46 build sheet to gather the following information which is believed to be the most accurate assessment on the interwebz:

Is it possible to determine whether I have a ZHP simply by looking at the VIN alone?
Answer: No. Looking at the VIN, without pulling a report (a dealer can do this for you) that shows all of the options that came with the vehicle, would not yield any clue as to whether you have a ZHP. Indeed, while you can look at the VIN on an M car, in total isolation, and know that you have an M car, such is not the case with the BMW 330 ZHP.


Question: What is the ZHP's 0-60 time?
Answer: In September 2003, Car and Driver magazine tested the vehicle and reported a 0-60 time of 5.6 seconds (http://www.caranddriver.com/reviews/car/03q3/bmw_330i_with_performance_package-road_test).


Question: what does the code ZHP stand for?
Answer: based on other package names, I'd go with horse power. But Dane, who knows a thing or two about BMWs, thinks it could just as easily be high performance.

Consider this:

ZSP=sport package.
ZPP=premium package
ZCW=cold weather package.
ZHP=horse power (or high performance) package.

Because the ZHP only has 10 more ponies than the standard 330, I have a tough time thinking that it's high performance. Horse power, though? Yes. About ten more horses, thank you very much. Who knows, though. Still, we think it's a logical guess that it's horse power or high performance (after all, it is the performance package, right?). Regardless, we definitely think it's something along those lines.


Question: Was the ZHP available outside of the United States?
Answer: No. The ZHP package was a United States-only option. But read below for more clarification on whether other countries received the US-equivalent of the ZHP package.


Question: What about the BMW 330 vehicles in the United Kingdom that look just like the ZHP-optioned cars that were available in the U.S.?
Answer: Those cars were equipped with the M Clubsport package. They looked very similar to the U.S. counterpart, but they did not get any of the engine modifications. It was a purely aesthetic package. The M Clubsport package did shed weight from the car, which brought its overall weight below the U.S. ZHP cars.


Question: And what about the BMW 330 vehicles in Canada that look like the ZHP in the United States?
Answer: Canada was different. In fact, BMW created the M Performance Package in Canada. It not only got the looks of its US counterpart, it also got the upgraded camshafts and engine tweaks. One thing that it didn't get, though, was the red needles on the instrument cluster. Moreover, the redline is at 6500 RPM, even though the car will rev to 6800 RPM -- just like its US ZHP counterpart. It also got the BMW Performance Package exhaust with the thinner walls (exactly like the one on the ZHP). Therefore, while it was not given the ZHP code name, it's simply a ZHP by another name. Indeed, it was given the option code of ZAM.


Question: I know that I've seen other BMW 330 vehicles in Canada that look like the US ZHP and the Canadian M Performance Package. However, they did not get the upgraded engine tweaks. What was that version called?
Answer: That's the M-sport package. The M-sport package came standard with 225 HP (like the stock 330) but it got the M-tech II Aero body kit. The M-sport package has the standard 330i thick chrome exhaust tips with the flap inside of the right-side tip.


Question: And what about Mexico? Didn't they produce a BMW that looked exactly like the ZHP in the United States?
Answer: Yes. It was called the F1 Package and it was available on the 320i. However, it was the equivalent of the M-sport package found in Canada, which did not get any of the upgraded engine modifications.


Question: What is the final-drive ratio on ZHP-optioned cars?
Answer: The final-drive ratio for the manual transmission is 3.07, which is shorter than the 2.93 rear end that was available on the standard BMW E46 330. The final-drive ratio for the automatic transmission is 3.64, which is shorter than the 3.38 ratio found in standard E46 330 vehicles.


Question: How does the ZHP suspension differ from the normal sport suspension?
Answer: The ZHP suspension is the Sport Package suspension with upgraded lower control arms (LCA); the BMW Performance suspension upgrade kit is the same as the ZHP's setup (ZSP + LCAs). Still, there are many different sway bar part numbers -- and none that are ZHP-only.


Question: How do the ZHP engine parts differ from the BMW Performance engine upgrade kit?
Answer: The ZHP engine upgrade and the BMW Performance upgrade kit are one and the same: hotter cams, oil pump spindle nut, and ECU software (+300 rpm). The ZHP differential ratio is also the same as the BMW Performance differential (3.07 for 6MT). The ZHP, meanwhile, has a rear muffler that is unique -- and different -- from the BMW Performance exhaust kit.


Question: It appears that the ZHP package has quite a few BMW Performance parts. What more is needed to have a complete "BMW Performance car?"
Answer: The ZHP package would need a BMW Performance intake, strut brace, brake rotors, exhaust, short-throw shifter, shift knob, handbrake handle, pedal kit, black grills, carbon fiber splitters, carbon fiber rear diffuser, carbon fiber trunk lip spoiler and style 269 wheels. In other words, there is still quite a bit more necessary to have a ZHP that's outfitted with all of the BMW Performance parts.


Question: Wait, I thought the BMW Performance exhaust system and the BMW Performance Package (ZHP) exhaust system were one and the same. They're not?
Answer: they are not. You can see pictures of them below. What's more, they have different part numbers, too. The ZHP exhaust system is part number 18-10-7-919-236 (18107919236) while the BMW Performance system is identified by BMW part number 18-10-0-429-614 (18100429614). As you can see from the pictures, the BMW Performance system is comprised of a muffler and exhaust pipes (we call these two parts the rear section). Clamps are also included, so that you can connect the BMW Performance rear section to the factory mid section.

Question: Didn't you mention that the SMG was not an available transmission on the ZHP? If that's true, why are there SMG parts available for ZHPs?
Answer: It's believed that BMW originally had hopes of offering the ZHP with an SMG transmission. However, something must have changed along the way. Indeed, customers report that they saw SMG as a possible option on the car when they were ordering their ZHP. However, when they tried to order the car with the option, they were told that it was not available. It is not known why BMW never made the SMG available for ZHP owners. However, one can still find a few parts that will enable them to swap their 6-speed manual or automatic transmissions for SMG. There are, in fact, ZHP-specific part numbers for the SMG controller unit and the SMG dash.


Question: What is the top speed for the ZHP-optioned car?
Answer: Because the speed limiter was removed in the 330 ZHP, the top speed is 155 mph.

Question: What is the steering ratio for the ZHP?
Answer: The ratio is 13.7:1. The part number is 32132282296.


Question: Is the shift knob in the ZHP 330 different than the one found in the standard 330?
Answer: Yes. The ZHP got a weighted (and shorter) shift knob that is highly sought after. It's not unusual to see people put ZHP shift knobs on their non-ZHP BMWs.

ZHP shift knob on the left and stock shift knob on the right:

Question: Is the ZHP short shifter the same as the BMW Performance short shifter?
Answer: No. Notice the curve and the distance from the ball center on the BMW Performance short shifter.

Picture of the two short shifters (ZHP on top; BMW Performance on bottom):

http://img.photobucket.com/albums/v125/marcussandiego/bmwperformanceshifter.jpg~original

Note that the short shift levers were upgraded for both the ZHP and the BMW Performance at some point. Therefore, you can find two part numbers for each.

ZHP short-shift lever: 25117543187 (newer); 25117523846 (older).
BMW Performance lever: 25117528881 (newer); 25117522917 (older).


Question: Did the BMW 330 ZHP come standard with Xenon lights?
Answer: No. Xenon lights were an option.


Question: I've seen BMW 330i, 330Ci, and 330CiC. What's the difference?
Answer: The 330i is the sedan. The 330ci signifies that it's a coupe. And the 330cic means that it's a convertible.


Question: Did the ZHP come in the 330xi (the all-wheel drive 330)?
Answer: No. It was only available in sedan, coupe, and convertible with rear-wheel drive.


Question: Do the kidney grilles on the coupes and convertibles fit the sedan?
Answer: No. They are different sizes. The coupes and convertibles have bigger kidney grilles. Therefore, if you're looking to buy kidney grilles, be sure that you get the right one.

Question: I've noticed that some ZHP-optioned BMWs have reflectors on the front bumper while others do not. Why is that?
Answer: That's a good observation. The coupes and convertibles have amber reflectors on the front bumper while the sedan does not.

Question: How much oil does my BMW 330 ZHP require?
Answer: An oil change, with new filter, calls for 6.9 quarts. Therefore, make sure you buy 7 quarts.


Question: how often should I change my oil?
Answer: BMW suggests 15,000 miles. Many enthusiasts, however, recommend changing it every 7,500 miles.


Question: do ZHPs come with rear fold-down seats?
Answer: Actually, the answer doesn't depend on whether it's a ZHP or not. All E46 coupes had fold-down seats (standard). Sedans, meanwhile, only got fold-down seats when the customer ordered the fold-down seats (option code 465) or when they ordered the cold-weather package (ZCW), which provided for fold-down seats as well. Therefore, the 2004-2006 ZHP coupes have fold-down seats. The 2003-2005 ZHP sedans have fold-down seats if the customer ordered them -- either as a standalone option or as part of the cold-weather package.


Question: I've seen two different interior-trim styles in the ZHP. Which was standard and which was the option?
Answer: The 330 ZHP comes standard with black cube trim. The silver cube trim was the option. And this note: when you look at the black cube trim closely (in person), you'll notice that there is quite a bit of purple color in it.

Question: What are the stock sizes for the 135M wheels that come on the ZHP?
Answer: They are 18x8 in the front and they are 18x8.5 in the rear. The front wheel's offset is ET47 (named IS47 on the wheel itself). The rear offset is ET50 (named IS50 on the wheel itself).

135M wheels:

Question: What about the tire sizes?
Answer: The OEM setup calls for 225/40/18 in the front and 255/35/18 in the rear.


Question: what are the part numbers for the front and rear 135M wheels?
Answer: The front wheel is BMW part number 36117896470. The rear wheel is BMW part number 36117896490.

Question: how can I tell a fake 135M wheel from a real one?
Answer: a real ZHP wheel will have a BMW stamp on the inside (backside) of the spoke. Additionally, it will have the part number stamped on the wheel as well (see previous part numbers). A front 135M wheel will have an offset of IS47 on it, while the rear wheel will have a stamped IS50 on it. See pictures below.

Question: Does the ZHP-optioned BMW 330 come with Bluetooth already installed?
Answer: Your ZHP will only have Bluetooth if your car was ordered with BMW Assist. If it wasn't, then your car is not equipped with Bluetooth. That said, our cars are pre-wired for Bluetooth capabilities from the factory. Thus, you can make your car Bluetooth enabled by installing the necessary equipment: TCU or ULF, Bluetooth antenna, and a microphone. Plug it in and your car is Bluetooth equipped.


Question: How can one tell that a particular BMW E46 330 is a ZHP?
Answer: We've already mentioned the interior trim, but other things to look for include: red needles on the instrument cluster (remember, no red needles on the Canadian M performance package), a 6800 RPM redline (remember, the redline is located at 6500 RPM in the Canadian M Performance Package), 135M style wheels, M-tech II body kit, Alcantara seats, Alcantara-clad steering wheel, shadowline window trim (it's high-gloss black on ZHPs), trunk lid spoiler (unless the customer ordered it without; see below), anthracite headliner (looks black), sport seats, etc. Coupes, meanwhile, also had clear turn signals, which could be found on the headlights, sidemarkers and tail lights. Sedans retained their amber turn signals.


Question: So, if the car doesn't have all of those features, it's not a ZHP-optioned 330?
Answer: Not necessarily. Customers could order the car with leather seats (option) and a perforated leather-wrapped M steering wheel (option). What's more, during the spring of 2005, BMW stopped putting Alcantara steering wheels on the ZHP (because of problems with premature wear), which means there are many ZHP-optioned cars on the road today without Alcantara steering wheels. Moreover, before BMW discontinued the Alcantara steering wheel, it also replaced many wheels under warranty, replacing them with leather wheels. Yet another reason why you'll find leather wheels coupled with Alcantara-clad seats. Additionally, while the trunk lid spoiler came standard, there was an option to have it deleted (option code 326). And this side note: some ZHPs, in early 2004, did not come with the trunk lid spoiler (even though customers did not choose option code 326) -- because of a parts shortage. Customers who complained eventually got them installed at the dealer at no cost (covered under warranty). Finally, word on the street is that convertible ZHPs didn't even have an option for the trunk-lid spoiler -- shortages or not. Therefore, if you see a trunk-lid spoiler on a convertible, it was placed there by the end user and not by the factory. Don't be surprised, then, to see that there may be slight fitment issues (too wide, for example) on the trunk-lid spoilers you do find on convertibles.


Question: I've noticed that some ZHP-optioned vehicles have black exterior trim that goes around the car. Why is that?
Answer: The sedans came with black moulding. The coupes and convertibles came with body-matched trim. That's why you see some cars with the black trim and others without it.

Question: How about the sidemarkers? Some are amber (orange) while others are clear. Why?
Answer: sedans got amber sidemarkers. The coupes and convertibles, meanwhile, got clear sidemarkers. What's more, the shapes of the sidemarkers are different. See the pictures below for an example.

Coupe and convertible sidemarker:

Question: What colors did the ZHP come in?
Answer: Imola Red, Mystic Blue, Silverstone, Alpine White, Jet Black, Silver Grey Metallic, Oxford Green, Black Sapphire Metallic, Steel Blue, Steel Gray, Orient Blue, Grey Green, Electric Red, Titanium Silver, Monaco Blue, Sparkling Graphite Metallic, Sonora Metallic, Quartz Blue Metallic, Deep Green Metallic, and Topaz Blue.


Question: Is the BMW 330 ZHP special?
Answer: Not according to this video (http://www.zhpmafia.com/forums/showthread.php?983-Nough-Said-My-BMW-330-ZHP-Is-Not-Special-%28a-video-by-Kayger12%29).

In Canada, this car is called the BMW 330i M-Performance Edition. We did not have Pkg code ZHP, instead we had Code 767 - Performance Package. Also, the SMG tranny WAS an AVAILABLE option when the car came out. They are extrememly rare but I have seen a couple in the flesh.

The code for the ZHP is actually Code 767 - Performance Package in the US too.

[Hermes]

I swear I read somewhere that the ZHP also got a different steering rack rate in between regular 3er and M... anybody know?

[Marcus-SanDiego]

The ratio on the steering rack is different. Something like 15.4. Something like that. I hear that some M3 guys have been putting the ZHP racks on their track cars. Not a cheap mod.

All 2002+ 330s get a 13.7:1 rack; it's not unique to the ZHP. The difference in the ZHP's steering feel seems to be a result of the control arms alone. The ZHP/330 rack is indeed quicker than the M3 rack. It isn't all that expensive of a mod either, I've seen the racks go for $250 on eBay.

I'm personally going to try retrofitting either a Z4M coupe or E9x M3 rack (12.8:1 and 12.5:1 respectively)

^^ Interesting how it lists the window trim as "high gloss satin" it's a bit contradictory!

How so? You think it should be called shadowline?

[E_Rak]

Well high gloss implies, well, gloss. Whereas satin typically refers to a matte finish..

I think it may be worth adding that the Steptronic ZHPs got a finned differential cooler.

[wsmeyer]

Excellent info!

For model year 2006 the ZHP option was $3600, at least for my convertible.

Also, the convertible was the only E46 chassis available in 2006.

Yup. I had been reading about the Turner LSD options on their site and saw the cooler for sale.

Swore I had one, and initially thought my car had been modded.

Research showed all Steptronic ZHPs have it. Cool.

[Schlag96]

Is there really only 83 AW/BLK sedans total?????

I need to snap mine up.

[danewilson77]

Bump.

The friendliest forum on the planet!

[shrp11]

Only 10 cars exactly like mine anywhere on the planet - that's pretty neat ;)

06, Monaco Blue vert, 6 speed.

With some mods there will only be 1 exactly like yours on the planet. :biggrin

Taken from the BimmerFest E46 Wiki with some mild editing (link: http://www.bimmerfest.com/wiki/index.php?title=BMW_E46#ZHP_-_Performance_Package):

Per the BMW press release, this package included the following changes. However, many of these claims have been found to be misleading:


Engine mods that equal a gain of 10HP & 8 ft/lb of torque by reprogramming the Digital Motor Electronics to allow a 6800 RPM max (up from 6500).
6 speed short throw shifter (for manual transmission equipped cars)
3.07:1 Final drive ratio w/ manual trans instead of the standard 2.93:1. Convertibles retained the already installed 3.07 ratio.
Max Speed Limiter set to 155 mph (instead of 128)
New M suspension, more "sporty" than standard or poor road package.
There are no "ZHP" specific springs. The same springs are used for comparably equipped 330's for both the ZSP and the ZHP. In both cases, the spring rate for the post 4/01 build ZSP and ZHP is believed to be slightly less than that of the pre-4/01 ZSP
Firmer shocks (Jounce: front +50%, rear +20%), (Rebound: front +35%, rear -8%)
ZHP does use different dampers than the ZSP. There is a shortage of shock dyno data, but based on the SACHS damping parameter values it is believe the jounce damping is the same but rebound damping is stiffer on the ZHP. Pre-4/01 sport package cars had similar damping values to the ZHP but used the higher grade SACHS "Advantage" dampers rather than the "Super Touring" model.
Smaller diameter anti-roll bars: 23.5 mm front (v. 24mm pre-04/01 ZSP), 18mm rear (v. 19mm pre-04/01 ZSP)
There is no 18.5 mm rear sway bar offered by BMW for the E46.
More rigid forward bushings
Front Control arm bushings are the same ZHP/ZSP
ZHP control arms are different and use a stiffer ball joint
Lower ride height by 15 mm (.6 inches) utilizing shorter auxiliary springs (Since both the ZSP and ZHP use the same springs, they have the same ride height. Both are 15mm lower than a non-sport E46 -.5 degrees of camber (for a total of -1.1 degrees) Alignment settings are the same ZSP and ZHP)
Exterior trim elements (front & rear fascia, trunk lid spoiler)
Special exterior trim: Anthracite (charcoal) headlight surrounds, High-Gloss
Shadowline (black gloss) trim
Large diameter stainless steel dual exhaust outlets
Extra thick Alcantara steering wheel (later switched to perforated leather)
ZSP Sport Seats
Alcantara & cloth upholstery to replace leatherette and standard trim (leather still optional)
Choice of "Black Cube" or "Silver Cube" interior trim
Red needles on the instrument cluster
Style 135's are added, 18x8.0" front, 18x8.5" rear
Wider Tires: 225/40ZR-18 in front and 255/35ZR-18 in the rear.
Reduced steering rack ratio. 13.7:1 versus 15.5:1 (All post 4/01 330's use the same ratio steering rack. The ratio of this rack is 13.7:1, it is believed to be different from that used on the 325's)

Thanks for this!

We should probably clarify the last item about the steering racks to state that the ratio is the same as 330, but the ZHP rack is different in that is has a weightier feel. Same part number but is actually slightly different physically.

That hybrid list doesn't mention the cam changes. The cams have a different profile, right?

[BMWCurves]

Not sure why it's not listed in BimmerFest's wiki, but it is mentioned in our FAQ. There are different part numbers:

Standard intake camshaft: 11317500388
Performance Package intake camshaft: 11317919241
Standard exhaust camshaft: 11311435416
Performance Package exhaust camshaft: 11317833596

You should update them then. :thumbsup

Smaller diameter anti-roll bars: 23.5 mm front (v. 24mm pre-04/01 ZSP), 18mm rear (v. 19mm pre-04/01 ZSP)


Having just put a larger M3 front bar in place in my car, I'm a bit puzzled by this. Why would smaller bars in a performance-oriented car have been seen as a plus?

Also: are the trim rings on the gauges part of the ZHP package?

All 330's have them.

I'm bumping this out of puzzlement...

Because larger bars don't necessarily equal higher performance. BMW's engineers were looking for a certain balance or feel so they decided to make a few changes. It's the sum of the parts that matter.

Hi All,
I just bought a 2004 330i ZHP with 186k miles. Is there a checklist of maintenance items I should be looking for or at given this car's mileage? Any help you can provide would be most appreciated.
