Can't believe the price on that gallon of paint, but at least you got it while it's still being produced.

Red is one of the priciest colors.

Today is one of those days in the Pacific Northwest, 75* and perfect. So I had all my cars outside and snapped a pic. The A5 is has sold as of today FWIW.

Maeve came with e34 H&R springs which is a little weird.
So, I am going to replace the springs with e28 lowering springs. As long as I’m starting from scratch, I thought I’d ask those of you that have gone through this if you have any preference between Eibach and H&R?

The last two e30’s I owned had H&R on one and Eibach on the other. Frankly I thought the Eibach rode better and the car’s stance looked better. But that may not translate over to e28’s.

Any one have an opinion?

Ran Eibach's and HD's on Das Biest for 10 + years with no complaints.

I have the same coffee stain on the carpet. Didn’t people drink anything while driving back in 80s? I’ve been working on some e28 cup holder solution, but haven’t finished yet.
Curious to see how the 3700 m30 work out.

Me too. The performance should be equal or better than the ‘88 M5 (sorry M5 gang, no disrespect intended).
So far I’m starting to realize my budget is too low

Metric Mechanic's old MM3900 engine was rated at 300 hp with L-jet back in the 1990s. One was put in a silver 1977 e12 530i owned by Jay Jones and featured in European Car magazine in 1993, it did some impressive burnouts.

There is much skepticism about MM HP numbers. And I do recall both that magazine, the writeup, and saw it (I think) in SD at 5er Fest 2004. But a good running 10:1 3.5 is impressive, especially in L jet, which probably gives a better torque curve, but less absolute HP than Motronic. With admittedly very old tires, once I got my euro 3.5 running right in my E12 I could spin the tires at will in first gear. Clutch out, just push down on the loud pedal and they'd spin. M5s are heavy, M5 territory? I dunno. Maybe. Maybe not. They might, or might not, have hit 300HP, but with 3.9, higher compression and more cam I'm sure it was/will be impressive. I'm suspect an M5 would pull it on top speed, but up to 80 or 100 MPH it might be a contest.

MM is quoting about 285 hp.

If you go to their website, read the write up about their design, much of it is what someone like me would do on their own. Other than the reason for the new pistons which from an engineering standpoint is outside of my engineering background. Everything I’ve read makes sense.

As I mentioned before, I was going to attempt to rebuild the motor on my own which is within my mechanical capability. But after talking with Jim, there are more than a few areas where the tolerances are outside of my scope to measure and adjust. And there is way more to building a motor than a cam and high compression. So for once in my life I am happy to pay someone else to scrape their knuckles and pull on a torque wrench. It wasn’t a easy decision as I’ve never paid someone else to work on a car that I can work on.

The proof will be in the end result eh?

I am looking at the 1993 article right now, can you believe this was nigh on 30 years ago?! They said to get to 300 hp you had to use yellow D-jet injectors, and even got 57 hp on a test with a D-jet blue injector. Whatever the result, the car seemed powerful. Yeah, I remember seeing pictures of the car (Barnyard Bimmer) on First Fives concerning the 5er Fest back in 2004. I believe Jay Jones still owned the car at the time. Back in those days there were still a healthy number of e12s around.

Proven fact, the 2 valve Euro M30B34 motor (3,430 cc) was hotted up by Alpina for Group A racing in several countries (635CSi), and that motor made 295 hp at 6,900 rpm, and they had an Evo 2 version later that made 310 hp at 7,200 rpm. And of course the e34 M5's S38B36 motor made 315 hp at 6,900 rpm. This is all DIN hp. Group A racing was pretty production car related, so yes, you can get big numbers out of a M30.

MM says they used a 95mm bore piston on the 3.7L and 3.9L, an 86mm stroke on the 3.7L, 90mm stroke on the 3.9L. The M88 and M90 motors had a 93.4mm bore (and people thought that was pushing it) and BMW used 94mm when racing the IMSA CSL e9 coupes in the mid '70s. BMW X-rayed the blocks to check if there was enough cylinder wall to make it safe.

From Jim Rowe's description of the MM 3700 Rally engine's internal work, the 285 hp dyno figure seems legit. After all the s38B35 only had 9.5:1 and smog gear. BMW's factory figures for the final toxic Euro 218 hp 635CSi was 0-60 mph in 6.8 seconds and 138 mph, for the 256 hp US M6 (s38B35) factory figures were 6.8 seconds and 142 mph.

I think you made the right move. With a Motorsport engine you pay through the nose for horsepower that a M30 can get close to. Alpina's 3.5L and AC Schnitzer 3.7L were around 260 hp, not far from the M88's 286 hp. Group A racing 635CSi only used the M30. The following video is of a 295 hp coupe:

1985 Group A 635CSi

LS V8 swaps and turbo M30s would bring more power, but wouldn't be a drop in engine swap like the Metric Mechanic unit. Turbo M30 and LS swaps involve custom re-engineering, especially LS swaps. At least with a turbo M30 you could start with a M106 and build more power than the stock 252 hp, but LS swaps would involve different gearbox, special propshaft, diff and axle half shafts to handle the torque, plus all the engine wiring harness match up troubles. You would need a donor C6 Corvette, and swap a lot in. At least with the MM3700 engine the spending and work stops when you buy the motor!

minimal progress over the past couple weeks to report. First it was framing my wife's "she shed". Then it was COVID last week. After 2-1/2 years both my wife and I caught it at the same time. bummer. Feeling better now so trying to get some things done.

Refurbished the chrome rings around the headlights. I don't have a before pic but let me say, they weren't shiny, at all. And then replaced all bulbs with the help of Daniel Stern. If you haven't used him for headlight help, he's one of the good guys IMHO.
nice and shiny


Part of buying used cars is not knowing what you're getting, like frozen corroded headlight adjustment screws. Soaked them in white vinegar overnight and a lot, not all, of the rust came off. They turn now at least. So back into a fresh batch of vinegar and then assembling them with the lights into their headlight brackets which have been repainted black. That and installing a headlight relay kit as well.



The Hella's are getting old, and my eyes are getting old. I'm hoping I'll be surprised when I finally drive at night. One of the challenges to living in the great Pacific Northwest is the long winter months, where its 4:30pm, its dark and its raining. Great headlights are a big deal around here and Maeve will be my daily.
Daniel Stern has volunteered to send me a list of what parts are needed to be able to install modern headlights. Maybe down the road.

The € lamps were a downgrade from the Cibiés that were available in the late 80s. But since they are NLA and the better CSR Cibié is also NLA the € might be adequate. Better than US sealed beams for sure. If you need more lumens, I'm sure Daniel knows what will work best in these cars. Wonder if there is a set-up for the € buckets as they use a set of unique lamps.

yes and there in lies the problem with trying to adapt modern headlamps to an e28.
As I mentioned Daniel volunteered to send me a list of necessary parts to be able to modify the buckets to accept newer tech lights. I'm sure he'd send it to anyone.

I am very happy with my LED headlights, but it was a gigantic pain in the ass to fit them in the euro housings and they were seriously expensive. I would consider doing it again on a car with US headlights but not a euro one, I'm interested in seeing how your headlight performance turns out.

I believe US buckets and grills are available for near nothing. Wonder if the modification would be way cheaper, way easier, and work as well. Just missing the € look.

Yeah the us buckets would be easier to use at least for the LED bulbs. You can just drop in any sealed-beam compatible unit, might need to do some trimming of the bucket to get it to fit. For the euro housings I used I needed to cut off almost the entire bucket, do a lot of epoxying, redo the adjuster system, all kinds of nonsense.

Mr.Stern would probably go this route, and suggested to me in emails with him to revert back to US buckets and grills. I'm wanting to keep the euro look and see what the upgrade in bulbs, new headlight relays etc mean for headlight performance.

Between the two, Eibach. I'm not a big H&R fan.

Really, the best is Dinan. But you may have to wait a looooooong time to find a set...

This goes to show how subjective preferences are. I really like H&Rs and I am not a fan of Eibachs at all. Unfortunately, I haven't ever driven on a set of Dinans, so I am of no use there.

I've driven both and like the Eibachs, but the dilemma is solved Anyway.
I couldn't find a dealer that had e28 eibach springs so I bought H&R's.

Small steps to report but necessary steps.

First was reassembling the Euro headlights. They are held to the buckets with a snap in ball and socket design. After careful cleaning and lubing with a light grease, I snapped in the first ball and guess what, the bucket cracked. So off to FCP Euro to order 6 new buckets.


And then I needed to clean the old adhesive tape off the back of the 535is emblems in order to have a clean surface for new 3M double sided adhesive tape made for emblems and logos.

Clean. What'd you use?

A box cutter scraping and scraping for about 30 minutes.
I am afraid to use acetone or parts cleaner in case it damaged the emblems, as they are NLA I believe.

I have to reattach the emblems on my '87 325is. Same style as the E28.
What specific 3M tape are you using? Please let us know how it works out!

I ordered this tape after reading reviews of this and others.
https://www.amazon.com/dp/B093Q2BRSD?ps ... ct_details

I have used 3m tape before on a '73 2002 my son and I modded. The rocker panel trim wouldn't fit correctly because of some big boxer flares we had put on the car, and I used a double sided 3M tape like the one above. Some people laughed at it but we ran the car for a while in the wet and dry and it was rock solid.

Check out https://www.3m.com/3M/en_US/p/d/b40065949/

that looks interesting, is it putty or something similar?

Here's the first step, trimming the tape to the inside edge of the emblem


but here also is a potential problem, or, I got it exactly right (I love luck), is the tape thick enough to adhere properly?


By the end of this project I think I may go through about every piece of this car, out of necessity.

The acid test so to speak. First locate the bottom of the logo with blue tape up 18mm or a smidgen less than 3/4" from the bottom edge. According to the BMW manual link HayekFan posted, the 524 td logo starts in 120mm, or 4.75" in American, from the edge of the trunk lid to the right edge of the "4". There was no reference to a 535is logo so the 524td logo is a close as I can get. Then 21mm, or about 7/8" the to left edge of the "t". I shrunk that gap to 3/4" as there is no cross on the "I" of the logo.


I believe I am lucky in that it seems the thickness of the 3M tape is just right. Off comes the red plastic backing and then place and press firmly.The tape is holding, now wiggle at all.



And then polish the chrome parts of the taillights. Amazing after 34 years of weather, dirt and grime the chrome polishes to almost new. And makes the rear of the car look better!


Would anyone that has an unmolested 535is logo check my measurements above and tell me what yours are. I don't think I'd move mine but I'd like to know how close I got.

So sexy. Keep it up!

why the American measurements? The car is metric from the front to the back including the spacing of the model insignia on the trunk.

Metric 17mm-18mm-19mm as you go up in size.

American measurement
11/16 for both 16mm and 17mm
3/4 for both 18mm and 19mm

and the numbers don't even count up

Unless you work with US measurements regularly, the ease of metric is obvious.

//rant off.

It looks nice and this one will be a fine example when you are done. Does look like you will be messing with every part as you said with the level of detail you want to achieve.

Well shadow, sarcasm or dry humor is almost impossible on the interwebs. My bad attempt on humor, but also pointing out the real world. I have a caliper that would orient the logos within .001”, but what’s the point?

In a perfect world, base 10 is much easier than base 12. Point well taken. I was too lazy to get my caliper and used my tape measure instead.


Progress for the next few weeks will be sporadic. I need to finish our shed, and the MM motor won’t be here until after November.
