528e Super ETA?

Hi guys,

Can anyone help me identify if my 528e has a Super ETA engine. The details are:

Chassis number: WBADK730XJ9833976
Engine number: 21336472

I'm interested in installing a JC chip but the vendor I spoke to before said that they don't have any for my VIN. I hope someone can anyone point me in the right direction.

Thanks a lot!

I'm not sure how to interpret the VIN number but I know the late 1997 and 1998 cars have a different system than the earlier cars and there is no chip available for the later cars.

The good news, the later models with the Motronic 1.1 system has about 7 more hp than the earlier cars.

Thanks for the reply Tidybouy! Much appreciated.

I also took your advise and ordered the book "BMW Enthusiast's Companion" from Barnes & Noble. I got my copy this morning and I haven't been able to put it down.

Maraming salamat! (Thank you very much!)

Great!

Another good book is the "Bently BMW 5 Series 82-88" repair manual. I like this book because it is specific to the 5 series. Many of the other repair books, out there, cover 3, 5, & 7 series cars & are too generic.

Thanks Vern! I'll order that next. : )

Since there doesn't seem to be any chip available for the Super ETA, do you think its still advisable to go on with the other mods mentioned in the book?
- Change to 325i camshaft, valve springs and throttle body
- Port head
- Change to 3.25 final gear

Aside from the last mod, I don't know if the rest are dependent on an upgraded chip.

That's it. Thanks again!

I am not an expert when it comes to the engine mods that you have listed. Myself, I have a completely stock 1988 528e. I plan on changing to a 3.73 final drive (when I find one). I believe that the M5's had a 3.73 limited slip and the 535is had a 3.73. This should add a considerable amount of low end improvement.

They do have a chip for the eta if your's is early 1987 or earlier. But, you have to have the Motronic 1.0 not 1.1.

I plan on keeping my car relatively stock but I am going to change the rear end and I also plan on finding some 16" wheels (basket weave) like what was on the M5's of that era.

One more thing, I have recently replaced all of my vaccum lines, fuel injector seals, and the oxygen sensor and that made a considerable difference. The engine is running perfect now.

Got it. Thanks Vern. I hope you don't mind if I follow your lead. Aside from H&R springs and Bilstein shocks, my car is also bone-stock. Just trying to extract a little more grunt from its humble engine. : )

As far as I'm aware, I dont think it is as simple as changing the head. I think you also need to use the I pistons and do some modfications to the oil galleys is order to make it work correctly.

If your DME is a 0 261 200 027, it is a regular eta motor. If it is a 0 261 200 153, it's a super eta.

(edited : sorry, 0 261 200 154 is the Super Eta)

Thanks for the tip Jared. I think I'll start looking for an LSD first then explore the other mods later on.

Hi Mark,

I'll ask my mechanic to check with DME I have. I guess either way, I'm ok. If its a Super ETA, then at least I have some extra hp's over a regular ETA. However, if my engine's a regular ETA, then at least I'll have access to some nifty aftermarket chips.

Thanks a lot! : )

Hi guys,

Help!

My mechanic plugged my car to his analyzer and this was what came out:

Motronic M1.1
0 261 200 154
E30 M20B27 w/ O2 sensor

I guess the last lines means that its an M20 engine with a 2.7 engine.

Since it has a Motronic M1.1, I suppose this establishes that my car does have a super eta engine. However, why does it show a different DME? Is it possible that what's installed in my engine is meant for an E30? If it is, does this make any difference given that both 325e and the 528e share the same engine?

Thanks in advance!


Manolet

Hello Manolet,
see my edited post above. The super eta DME ends in 154, I made a typo when I originally posted.
