The Random E46/ZHP Question Thread

[Archbid]

I have never heard a coil going out. How would you describe the sound? And how would I diagnose this since it’s so intermittent and no CEL? Sometimes in the cold during the rough idle, extra smoke would come out the exhaust (like a single engine stroke worth), but even that hasn’t happened in a while. I did have to reset adaptions for my manual swap too.

My friend has a spare set of coils. Perhaps I’ll ask to borrow them

Edit: I did buy VANOS seals and bearings and a DISA kit. The DISA from my old car fell apart upon removal 🥲

I have a bunch of spare coils you can have. Come by my house and grab them. Feel free to use my vice for the vanos job. I have done it 4 times and can do it in my sleep.

Wow, you're like my E46 god. I didn't even know you hang out here. Happy holidays Matt! I finally got rid of the old car btw, reinforced and manual swapped the new one. You haven't seen it yet! I'll have to put my new seats in before I reveal it to you, I'll fast track that project. I'll stop by some time in the new year. I need to do a rack swap and oil change ASAP. Diff bushings, DISA and VANOS are all in the mail on the way.

Can't wait to show you the new ride. I'll take you up on your offer on the vice as I was going to buy a new one otherwise. I think this'll be my fourth time too: the 328, the last 330, my friends z4, my friends ZHP motor that had bad compression...so this'll be my fifth. How's your wagon coming along?

Dumb question, but I guess that’s what this thread is for. Did all ZHPs come with electric fans? Mine has electric fan but I’m not the original owner. I have the records from the original owner which are exhaustive, but there’s no mention of electric fan conversion.

The ones with a manual transmission did.

I am everywhere

Wagon is running great. Got the mtech front bumper on and the engine in, then got a bad head injury and have been in pretty serious pain for a few weeks. It’s getting better tho. Should have the new tune on the wagon and the rest of the mtech on soon.

Come by the house anytime. I’m laid up and not going anywhere

Well we’re one and two. Today I woke up in agonizing pain. I went to work only to be in tears by the final turn. I walked in to say I was taking the day off. Easily most painful day since my accident. I’ll come out and say hi soon though. The car is so pretty and want to see the wagon. Make sure to take care of yourself

The manual cars had electric fans. Automatics had a mechanical fan.

Can anyone tell me the differences between the earlier/later manual transmissions? My car was built 3/4/2003. Accordingly RealOEM, etc:

6 speed gearbox    GS6-37BZ - THEB    1    03/2003        23007523981        ENDED   
6 speed gearbox    GS6-37BZ - TBEZ    1    ??/????          23007562725        ENDED   
6 speed gearbox    GS6-37BZ - THEG    1    06/2003        23007532498

It seems that GS6-37BZ - THEB was used from 3/2/2003 until 6/18/2003, while GS6-37BZ - THEG was used after 6/18/2003. Does anyone know what the differenced between the THEB and the THEG are?

Is there a preferred brand for hood / trunk struts (51238202688 / 51248254281, respectively)?

FCP Euro sells Stabilus. I would think that’s a good brand (made in Germany). Otherwise they would not offer lifetime replacement on them.
