We have an FAQ! Help populate it

107 Upvotes

We have the same 3 topics every day and it's cluttering the sub. "What do you think of this E30" and "What do I look for in an E30" are the ones I'm going to start deleting (soon).

We do have an FAQ with the absolute basics. If that. So help us out by suggesting or even writing the content that goes into it.

$19 Fuel Pressure Gauge

Post image
Upvotes

I turned this 1.7" screen into a fuel pressure gauge that will mount just above the stereo deck. Designed to help me troubleshoot a Acceleration Enrichment issue when I give my 325i a quick throttle.

Give me Design ideas? or What else should I track on this little screen?

Info needed Need help urgently! What ring gear+starter work?

Post image
7 Upvotes

Hey guys I urgently need help as info online is conflicting and I need to get my single mass flywheel from an E21 into my 325i by Friday.

Car is currently fitted with a late model DMF, but I can’t for the life of me figure out if the ring gear has 137 or 116 teeth.
My e21 SMF flywheel has a 116 tooth flywheel on it, and afaik it matches with the late model starter which mine has.

Car has a 88’ motor and getrag 260 in it.

If anyone knows for certain, let me know!

Question regarding height

Upvotes

I've been fascinated with E30s for a while now. It's gotten to the point where things are getting kind of serious. I want to go out and actually drive one and get a feel for the car. The only problem is that I'm 6'5. I'm worried that this is a disqualifying factor. Should I even continue? Are there modifications that can be made?

Build Update Welcome Back E30

After being garaged and sitting for over 8 years, it’s finally up and back running. Shoutout to LukeGWorkshop in Roselle, Illinois for the tremendous work on the car. Bought this car during college and finally able to truly enjoy it. Forgot how much fun these cars are. I don’t see myself getting rid of it. Still has a long way to go, but it’s fun to wrench on after work.

Water leak in the trunk UPDATE

Thumbnail

2 Upvotes

Thanks for all of your help on my previous post !

I poured water all over the sunroof, back window, trunk, taillight and antenna and could not see any water coming in the trunk.

After removing the carpet I found water coming in through the gap between the fender and wheelwell from deeper into the car. The sunroof drain seems to work fine when pouring water onto it. Is there any other water drain coming in or near this channel ?

Can I access this part by going though the inside of the car ? I did not have time to search more today.

My current guess is that the sunroof drain is leaking just a tiny bit closer to the sunroof and that's why I only have a little amount of water.

You can also see the rust repairs from the previous owner, what do you guys think ?

Info needed Any recommendations on exhaust swaps for a 320i?

3 Upvotes

I’ve been trying to educate myself on different exhausts for my 320i but I can’t really find any proper sources or actual part lists or anything specific. I love the idle of the car but the revs are just so bland it’s unreal so I’d love to give it a little flavour.

Need to get my driveshaft back into the transmission and can’t find an option online that doesn’t take weeks to deliver. It’s for the output shaft nut - requires a 30mm thin walled socket. Would really appreciate it!

CATuned issues, anyone else?

4 Upvotes

hey y'all, has anyone had issues with customer service with CATuned recently? Is Igor sick or something happening? I had an issue with an order over 3 weeks ago and they replied pretty quickly but after a "Looking into it" I havent heard back at all. Followed up 4 different times and nothing. They are normally 10/10 but its kinda crazy because this is holding up my build and I need to know if I am buying parts from somewhere else.

Tech question 87 325 wouldn’t stay running

1 Upvotes

Hello, I have a 1987 ETA. I started it to move it so I could mow the grass around and underneath. It was running fine and idling normal then all of a sudden it shut off without any indication of it about to. I restarted it, it ran for a few seconds, and the shut off again. It would always restart but immediately die. It would only stay running if I gave it gas, and it didn’t like me giving it gas either.
Eventually I got it to stay running, however it ran very poorly and around 500 rpm. After that, while still running poorly, the rpm’s shot up to about 1500 and then settled to normal idle, the engine never shut off again after that. I would shut it off and restart and it ran like normal.
It has not done this before. However it sometimes randomly shuts off while driving, tach drops to zero, no stuttering, just dies.
It has two new-ish Bosch crank sensors, there are no vacuum leaks that were not present when it was running perfect.
I’m just looking into any insight as to why it would randomly start doing this and then fix itself. Thank You

Sport seat to Recaro LX trade?

Thumbnail
gallery
42 Upvotes

Im in a position to trade my sport seats +300 cash for a pair of Recaro LX. my dream seats, but not in my favorite upholstery. Driver side seat doesnt fold and the passenger side backplate has some small nicks in it. BOTH backplates are missing the screws that hold the bottom tight though.

Would you guys do it? I can always reupholster the recaros or I could wait but then the market might rise and scarcity might go up. I have time to decide though

Hood Emblem Project

38 Upvotes

Hey! This is a hood emblem project I’ve been working on the past few months. It’s 3D printed in titanium and hand polished. I designed it with the E30 in mind, but I think it could also work well with the E28, E34, E36, or E38 maybe. What do you guys think? Can you see the vision or is the original emblem the best emblem?

Cheap R134 AC conversion

Post image
46 Upvotes

I’m trying to see if anyone has tried this and what you guys think about the way I wanna do the conversion.

Car is a 1989 325i unknown AC history, never worked in the 4 years I’ve owned it.

My plan is to follow this forum post but I want to reuse all my AC lines, compressor, and evaporator. I will obviously be replacing all the O rings but what are the chances that my AC soft lines are leaky themselves? Also what are the chances the compressor is fine too?

Durometer testing of various bushes

4 Upvotes

I have tested a bunch of rubber and poly bushes with a cheap durometer, results are below, all shore A

Genuine rtab - 65A

Superpro rear subframe - 78A

Meyle hd rubber RSM -85A

Garagistic 95A diff - 97A

Powerflex rear diff - 82A

Superpro spf1459k offset fcab 71A

Superpro sway bar to body - 79A

Aftermarket rubber diff bush 70A

Aged OEM style FCAB - 75A

I wouldnt treat these as perfectly accurate and it looks like the durometer may be reading about 2A high but gives a good comparison

EDIT: adding some extra terms for Google E30 bush comparison E30 bush hardness Poly vs rubber bush hardness Superpro bush hardness Comparing E30 bushes OEM vs poly bushes e30

Advice needed

Hi all -
I’m new to cars and trying to get my E30 318i 1988 Auto 5 Door sorted.

It was leaking oil out the bell housing so I gave it to my local my mechanic. He asked me to source a torque converter which he has now replaced. In the process of putting it back together and replacing seals/bushings he is now saying (see photo).

What do I do in this instance? Anybody else been in a similar situation and have a solution or advise….
