Good point, the other saving grace I verified yesterday is that the original horse hair seat sags by inches with age... New seat pads would be a problem.

Right. My 76 E3 has sunroof, height adjustable driver's seat, adjustable steering column and a worn seat. Only with all of this I fit in and feel comfortable, measuring between 6'4" and 6'5". A friend has offered a really nice seat to replace mine. It would look better but I am still very unsure about it.

Back to the red 3.0 CS. I like it a lot better than the Polaris one auctioned off earlier. It went to Sweden probably from day one, September 1974. Granatrot seems to have been quite popular in Sweden then, quite a few E3 come in the same colour. In Sweden rear seatbelts were mandatory, maybe that explains the unusual upper mount points for the front belts. The usual ones may have been needed for the rear belts. Also mandatory were headlight wipers which seem to have been gone. It has been discussed elsewhere that they are unnecessary anyway in nearly all situations. Correct doorpanels would have been a nice touch, though. A 1974 model should have panels with perforated vinyl, not the earlier version with the herringbone inserts. Probably better still to have a nice and reliable car with wrong doorcards than vice versa.
 
This car is certainly a looker! Can some of the experts on this forum explain two things to me please:

1) Do I understand this correctly that GermanyExclusive restored this car for Ivo Christov who himself is a well know BMW restorer, and now GermanyExclusive is selling it on his behalf?

2) I am confused regarding the power rating on this engine? Seller states "European M30B34 218hp..." but SFDon pointed out that these are dished and not domed piston and hence not the 218hp?
 
Hello everyone,

We opted for original BMW pistons specifically designed to complement the engine's original specifications. Our primary goal is to maintain the integrity and excellence associated with BMW engineering. In this case a M30B34 engine with a 10:1 compression ratio resulting in a compression of approx. 10 bar / 150 PSI.

Our engine builder has 30 years of experience with BMW M30 engines and he determined that decking the block was necessary to restore their surfaces to factory specifications. This process ensures a perfect seal at the head gasket.
Given the adjustments from decking, and selecting the OEM correct pistons we have matched the original performance metrics of the European BMW M30B34 engine, 3.4 liters and 218 HP. As you could see on the pictures of the compression test, we achieved the correct compression ratio.

The benefits of our configuration:

- Optimal Performance: The engine now performs at a level consistent with European specifications of a euro market 1985 635 csi, ensuring enhanced power and efficiency.

- Reliability: By using original BMW parts and adhering to stringent standards, we have ensured the engine's longevity and reliability.

- The final result? We hope you will enjoy the extra driver’s video that we'll shoot tomorrow!

About the cooperation with Ivo Christov, the car wasn't restored for Ivo but by our company, I invite you to check our website for more information:

Many of the people reading this thread or visiting BAT are my clients and friends.. This needs to be cleared up.

Suggest you look at your own website to remind you of what a piano top high compression piston looks like.


10;1 pistons are about 200psi compression.
10:1 piano top pistons look just like the ones on your own website.

I sincerely hope you just got your photos mixed.

OK- I posted on BAT. You have co-mingled pictures of early and later engines in your ad.
you need to fix this. Coupes don’t have 2 fuel pressure regulators.

Hi Don and fellow forum members,

Thank you for bringing this to our attention. I appreciate your involvement in this auction and your contribution to the BMW E9 community.
I appreciate the opportunity to clarify the situation regarding the pistons and the compression figures discussed.

1. Clarification on Piston Types: The pistons featured in the images on our website are general pictures for the BMW E9 3.0 CSi engine and not for the BMW M30B34 engine in the Granat Red BMW E9 in our current auction. The M30B34 engine from our BMW E9 on BaT uses correct OEM BMW pistons designed for its specifications, ensuring the achieved compression pressure of 10.0 bar (approximately 150 psi). The images shown are with a cold engine.

2. Compression Figures: As mentioned, our compression tests yielded a consistent 10.0 bar (150 psi) for the M30B34 engine. This figure is appropriate for the high-compression version of this engine model. We understand that higher compression pistons can yield higher compression figures, but our results reflect the specific configuration and condition of this particular engine after precise decking and piston selection. As stated on BaT, reliability of the engine is key.

3. BaT Image Mix-Up: We made a mistake by mixing up the photos on BaT from another engine, and I apologize to you, all members here on the forum, and those following our Bringatrailer auction. With several projects here in the workshop, we strive to document everything correctly and be fully transparent about all the components used for this E9. This mistake should never have happened, and I am fully responsible for this.
I will add two extra pictures on BaT to ensure that the engine is correctly represented to prevent further confusion and correct our mistake.

We value transparency and open communication with our clients and community members. Should there be any further questions or need for detailed explanations, please feel free to contact us directly. We are more than happy to provide additional information or discuss any concerns.

In closing: I appreciate the passion and knowledge shared within this community and look forward to continuing our engagement with you all.

Don, I send you also a PM so you have my phone number and I'm happy to talk and meet each other in the nearby future.

Best regards,
Eric Bunte
Germany Exclusive
 
Eric, i am no engine expert, but 10:1 compression should translate to somewhere around 190 / 195 psi in a euro m30 b34. i own one of these engines. the 150 psi number seems more indicative of a 8:1 compression engine - standard 3.0L m30 engine.

to be clear, this is a very pretty e9 coupe. you have achieved some high sales on e9 coupe ... and most of us couldn't be happier with your continued success. that being said, if you don't get your facts straight, this is likely going to change. and oh BTW, you don't want to argue engine facts with one of the best known engine builders and d-jet experts - our friend @sfdon ... as he knows more specifics about these cars / different engines than most people in the world.

i wish you good luck

Thanks Scott, I appreciate your words and your input in this topic. I have followed our chief mechanic and German specialists and I trust them 100% in their knowledge and experience. The last thing I want to do is argue with people so also not with Don from who I know is a very valued member in the E9 community. I'm convinced that listening to each other brings us further.
Thanks again,
Eric
 
for the record-





"The pistons on the B34 engine are either an 8:1 low-compression piston, or a 10:1 high compression piston. The 8:1 pistons have a deep dish, and are cleary recognizeable. The 10:1 pistons have a dome, with a grand-piano-esque shape.“

Thank you to @sfdon and @E9Eric for explanations - $131 + $5K = $136K for a US buyer with the import doc. fees and taxes, and shipping costs covered. Great car. Sundays are tough for me, or I would have been in there. Well done.

So Don's post has been flagged as not constructive and no longer appears in the thread on this car. I wonder how BAT defines not constructive given that (1) the seller clearly agreed with whatever it was Don said, (2) the seller took corrective action, and (3) the seller apologized.
 
I called out BaT on the comment issue. Will see what happens......
This is one aspect of BaT that really causes me hesitation to offer anything there (when/if it comes time for that).
They say they are all about transparency. But... not in what they do on occasion.
 
Free speech is inherently not free in another persons domain.
And we know that the BAT site is patterned after Craigslist where Community Moderation is the norm.

I can live with it. It is what it is. Glad they don't charge me a monthly fee for sharing my debatable wisdom!

I agree with you all, Don supported us by pointing out the mistakes and also advised me by PM messages and gave very nice comments about the car itself. His comment was very constructive for the viewers and for us too because in this way we were able to comment on our mistakes. Don, thanks for your support!
