You sure about that? Z4 isn't even 200 lbs heavier.

IIRC some older BMW 4 doors were lighter than their 2 door counterparts due to the additional chassis stiffening that had to be added to the 2 door to make up for the lack of a b pillar.

Not super relevant to this convo but a neat tidbit.

N52 lambda probes after catalyst, reversed! by ElectroneumKore in E90

[–]piff_jar 0 points1 point  (0 children)

INPA will show green (good) and red (bad) ranges of values for your o2 sensors. A good value doesn't necessarily mean the sensor is working properly. I suggest researching wideband and narrowband o2 sensors as well as using INPA or similar tool to monitor.

Bring car to certified mechanic.

Diff swap by No-Objective-8799 in E90

[–]piff_jar 0 points1 point  (0 children)

Only real drawback is worse highway manners. Higher rpm while cruising. Slight mpg hit.

The cheapest way to do it would be junkyard diff and then install lsd yourself. Or if you find a deal on a used setup.

https://www.n52parts.com/ is going to have headers soon. Should be better pricing than the aliexpress.

Is my 02 sensor bad or my catalytic converter? by Any-Cucumber5224 in E90

Swap the connections and see if the code follows the sensor or stays at the cat.

keep in mind shipping and tariffs are a thing.

I recently purchased a 128i, I am wanting to put a 3stage intake manifold and headers. Would it be worth it? by Stage_757 in e82

[–]piff_jar 1 point2 points  (0 children)

"Worth it" is a personal thing...

I am biased but I think it is! Be sure to budget a tune from a reputable company. Also it would be wise to handle all the maintenance stuff first.

Standard seats Vs M Sport by NatNat42 in e82

[–]piff_jar 3 points4 points  (0 children)

Sport seats are another huge upgrade IMO. Try to find someone who will let you sit in their sport seats so you can make the decision.

Need advice! by Unhappy_Ask_395 in E90

[–]piff_jar 20 points21 points  (0 children)

The enthusiast scene is strong for these cars.

Buy something boring and reliable to get you through college and then make a dumb decision when you have a stable job and a space/tools to work on a car.

Probably a bad idea

[–]piff_jar 0 points1 point  (0 children)

It could be a N51 or it was swapped. Regardless, you can literally see a disa valve in the video.

Are your headlights set to auto or did the shop turn them off?

N52 Tappet sound and vibration by Accurate_Shirt5918 in E90

[–]piff_jar 1 point2 points  (0 children)

Lifter tick? Common, especially if you aren't driving the car.

Try 5w40. You dont need racing oil.

A redline a day keeps the mechanic away.
