From my own recent experiences:

I was told that BMW Bore Wash was a myth.

It's a real condition!!!!!

while Cold Air Intake Internet Debate #43591 rages , I don't mean to be rude, but there are several points in the stickied OP that I would challenge:

- The point of 540i MAF is not to somehow trick the ECU into thinking there's a V8 under the bonnet to magically increase power. It is simply a bigger (ie less restrictive) MAF. So, for a modified engine which breathes harder, it is a way to remove the bottleneck of the smaller M50 MAF. Check out the r3vlimited threads for more info.

- For the headers, I assume "S50" refers to the US version. According to the part numbers, these are exactly the same headers. Also, for headers which are actually different, performance can actually decrease if the tune isn't tweaked to suit the new breathing. So I think retune/chips should be mentioned in this section.

- Ram Air Intake: aka high beam delete. Performance benefit (unless we're talking a monster S5x engine) is widely regarded as dubious, is there any proof to back up the claim "the most efficient and easy to produce modification"? Also, hydro-locking is serious stuff, I wouldn't be relying on a hacked up stocking to protect my engine...

- Springs/shocks/struts: Some more understanding of suspension basics would be worthwhile, in order to do an overhaul of these sections. Also, Bilstein aren't the only manufacturer of decent E34 sports shocks in the universe. At least Koni should also be mentioned.

- Braided brake lines: There are differing opinions regarding whether stainless lines improve braking performance for a street car. Personally, I suspect the claimed improvements may be simply due to putting in fresh fluids and bleeding the system.

That is a very ghetto sounding way to make the engine run leaner IMHO. If the closed-loop system is working, it just means the ECU has to compensate for the lower fuel delivery (probably asking for more than the injectors are capable of delivering at that fuel pressure). If closed-loop isn't working, you're just running leaner than BMW intended, therefore risking damage under load.

Actually, some good news, there's all kinds of upgrades out there for M20s. The M20 might be bottom of the E34 pecking order, but it's only below the M3 in the E30 range. So plenty of people have been tweaking them to squeeze out some extra horses.

The first M50s were non-vanos. So that takes care of the "most difficult" part.

Sorry if I sound rude, just some suggestions to consider.

Fixed that for ya. The MAF and AFM though similar in application aren't the same nor measure air flow the same. Though I understand what you're saying. Others may not.

Koni's weren't mentioned?!? Well at least you did now.

Truth be told your 100% correct. (I just had this conversation)

People have counted out the e34 m20 cars.
Kind of like what's the progressing notion on e34 m30 cars.
Yes it's old tech. The m20 isn't the best performer and some if not most swap them out.
Your interjection is exactly what needs to be said. People love them.

It's the love of these old grunts that has always been the foundation of the overall e34 enthusiast group.

Woops, yes, that dyslexic moment makes quite a difference! Thanks for picking that up.

Yeah, I've got a soft spot for the old warhorse M30 too. And the lighter E30 body means the smaller torque output of an M20 doesn't matter too much when you just want to get to the shops without ringing out every gear. I'm not trying to push the barrow of any particular engine, just wanted to highlight that M20 folks have room for improvement instead of going straight for an engine swap. There's everything from a chip to awesomely bonkers builds like this: http://www.performanceforums.com/for...th-TK-goodness (not to mention boosted options )

Cheers,
Simon

Known E34 Upgrades and Common E34 Myths

I have a hole in the exhaust of my 91 535i stock exhaust and I want to replace it with a performance exhaust that has a nice deep rumble. Any suggestions people? Something that won't cost me an arm and a leg.

YOUTUBE!!!!!!!!
Found a vid there and that made my decision on exhaust, but mine is 540i, so not sure how it would sound on your car. It is a nice deep rumble that i like too, not that ridiculously loud tuner sound.

Yah I'm really not into the tuner sound for this vehicle, which at this point it does sound like due to the hole in the exhaust. I looked on YouTube but could find and make, just descriptions of the exhaust

B&B, Remus, Eisenmann, super sprint, simon (not in the US...I think) Schmiedmann.

Outside of a magnaflow muffler or just creating your own exhaust.

That's just about it.

Hey guys. My windshield wiper motor burnt out on my 91 BMW 535i. Any ideas where I could get a new one for cheap?

^ This.
Or South26 aka Andy and another member who's handle I forgot.
They're both parting e34s as we speak.
Don't know the other guy but Andy is a solid seller.

Andy's thread: here

I got his name it's 92 535i manual. Heres his thread as well:

Re: Known E34 Upgrades and Common E34 Myths

Hi All,

Im new here. Wondering if anybody can tell me if I were to do an engine swap onto my e34, what latter model of engine would fit on to the e34 chasis. Here in malaysia parts n engines for e34 starting to become obsolete so I may need to consider changing to a newer model engine as my engine has been giving me a lot problems lately.

Appreciate it any reply and suggestions.

Each will need a little modifications due to the difference in size and mount positions But...

s38 (possibly the easiest for the m30 and the s38 are kin to each other)
m50
m6040
m62
m70
s50
s52
Basically anything that your time and bank account can afford.

I think he is more looking for more easily maintainable direct fit solution..

Basically, you just wanna move up one generation..

If you have an m20/m30 replace it with an m50/m52 what ever is available to you.

If you have an m60, and its hard to come by then hopefully the pre vanos m62 is available.

Both swaps offer equal performance and a newer motor that should be easier to find extra spares for..

Both witch i recommend an obd1 swap on.

Goodluck

Hi mysatindoll,

Thank you very much for the list of engine models as what I am looking for. At least it narrows down my search and I can learn abt each engine from here on and of course time n money is the essence. Haha.

Cheers!

Mein Auto: 1992 E34 535i 5spd
MySatinDoll,

Thanks for the nice info on the upgrades for the E34 535i. I've had mine for a week now. Sorry to hear about your recent accident. I hope it can be repaired to its former glory.

Besides what you mentioned I had a couple questions: My 1992 came stock with a 5 spd and LSD. What gear ratio does it have? It travels in 5th gear at 45mph at 2k rpms, 60 mph at 3k rpms, and 70mph at 3250rpms. I'm also wondering how to get better fuel economy. It gets about 15-16mpg around town and 19-20 on the hwy at 70-75 mph.

I was thinking of doing a tune up, although the PO did one in the past 10k miles, and I wanted to get an upgraded ECU chip which is why I had purchased the Alpina B10 3.5 ECU. I think now it won't work on my car, so maybe a TMS chip. Lastly I was wondering if a 6 spd trans could be fitted to the M30 motor to have a better final drive ratio. I would like to be able to get 18+mpg around town and 25+ on the hwy.

I am thinking to go turbo in the future but for now just need some reliable economy with decent stock power.

Thanks, Mark
