Tammer,
So much for heavy cars only!  ;-)
My old 318ti was not 'heavy'.  At sub-2800lbs most would consider it a
pretty light street car these days.  Besides, the question is for an e46
which is certainly well over 3000 lbs in any street trim.

For sake of full disclosure I ran a 215/45-17 size.
My experience with the Yoko ES100's was miserable.  Those tires made
more noise than anything I've ever experienced, even worn wheel
bearings!  I tossed them with considerable life left but they were NOT
long wearing tires either.  Horrid cool/cold weather (yet dry)
performance and I'd say poor wet weather performance.  On the track in
the dry, they were reasonable at best and based on my street experience
with them was a complete surprise to me.  I was so excited to wear them
down.  I've never been happier to spend the $700 on new tires.

Since then I've run the Michelin PS2 which has spoiled me beyond belief.
The best street tire I've ever driven-period.  Superior to my formerly
favorite S0-3's in every category.  I've run them wet (including serious
downpours) and dry at the track and on the street and I have been
thrilled with them.  Pricey, but you get what you pay for.  Silent, good
wear, phenomenal grip wet, dry, standing water, etc regardless of
ambient temps.

The BFG g-force sport would be my next low-cost experiment provided I
can pry myself from the PS2's to try something new.  A good friend has a
set on his P-car but has not put enough miles on it to get a very
worthwhile review. 


Cheers,
Chet Dawes

In my experience the ES100 do really poorly on heavy (>3500
lbs or so) cars, but quite well on lighter ones.  It seems
that most of the complaints come from drivers of heavy
cars.  They do get loud, but I'm willing to live with that.
I'm not in a position to pay more than 2x as much money for
5% better performance and 5% longer life.  I have been
shopping for a set for the E28 M5, and due to its weight
increase over the 535 I am looking for something other than
the Yoks ... I'll search for deals on the T1-S, good call.

Jason,
Don't forget the 235/40-17.....Last I saw they were like 2 pounds PER
tire lighter than the 225/45-17 PS2!  Wider, lighter and better gearing
for the same basic money.  :)
Check out the One-Lap-O-America results from last year if you want to
see wet vs. dry high end tires.  Same cars, same drivers, same tires on
the wet and dry skid pads at tirerack.

Oh and another negative impression I had with the Yoko ES100s.  Extreme
TRAMLINING.  Same alignment, same car, different tires (PS2 and S0-3)
had zero.

I've got a '93 E36 with the Alpine 6-CD changer.  The other day, I get
the message "DISC ERROR" on the head unit.  The CD changer appears
to have no have no power, check the fuses -they're ok.  Dig out the volt
meter, power definitely getting to the unit, however the cartridge won't
eject.  Anyone else run into a similar situation?  At a bare minimum, is
there some emergency release to get the cartridge out?  Thanks!

Did you check the fuse in the back of the CD changer?

To get the cartridge out, slide a business card underneath it, in the 
centre.  It will trigger the release.  If a disc is out of the 
cartridge, it will remain in the changer and you will have to dismantle 
the changer to get it out.

Pity I'm set for tires for quite a while.  I guess the followup question to the

San Diego is blessed with a number of very competent, even highly expert,
independent BMW specialists. You can get pretty much whatever you want
here.

When I need the help of a shop I most often use Apex Engineering even tho
it is not that convenient for me. Apex is, however, very close to Mission
Valley which is what you requested.

If you would like a list of other options, feel free to email me directly.

Subject: B25 swap
Message-ID: <[EMAIL PROTECTED]>

Does anyone have a good write-up on what's involved in swapping the B25
motor into an ETA.  I have not really found anything in the archives,
which I find hard to believe, but non the less, I am confused about a few
things, or rather ignorant.
What of the fuel system? Does it need to be swaped as well.  I have an 87
so it is the early Motronic, not the super eta system that was in the "i"
motor (Motronic 1.1 I think).  I assume the ECU has to be swapped, but
what about the electrical?  How much is plug and play, and how much needs
to be reworked?  I already have a 3.73 lsd.  Also I know the exhaust will
have to be changed, but is it the whole system, or just the muffler?  Any
responses to any of these would be appreciated, or a link to information,
or refrence to archived material I missed in my remedial search.

No good write-up, but as the owner and mechanic of an M20B25 engine I might
be able to answer a few questions.

>What of the fuel system? Does it need to be swaped as well.  

I don't think so. From what I have read in the various manuals and looking
at the parts lists, I think the fuel system can be left alone. While the B25
engine does use a higher fuel rail pressure than the B27 (4.5 Bar vs 4 Bar),
the fuel pressure regulator is on the rail itself and should be coming with
the engine. The fuel pump should be capable of over 80psi anyway, so there
should be no problem there. There was only one test procedure in the book
for all the M10/M20 engines in the E30s.

>I have an 87 so it is the early Motronic, not the super eta system that was 
>in the "i" motor (Motronic 1.1 I think).  

Ok, a little lost here... which is the '87? The B25 engine or the chassis it
is going into? From what I understand the Super-Eta engine ('88 only?) was
special. The B27 engines otherwise used the Motronic 1.1. The B25 engines
started with Motronic 1.1 and then moved to Motronic 1.3 in '88 when they
stopped making the B27 engines. I think.

>I assume the ECU has to be swapped, but

I would move the ECU with the engine. Although a B25 might run with a B27
ECU, the tables and curves will be wrong for the engine. Performance and
emissions will no doubt suffer.

>what about the electrical?  How much is plug and play, and how much needs
>to be reworked?  

I believe that the engine has a harness all to itself. The wiring on the
engine should move with the engine. There should be a harness for the ECU
that plugs into the engine, (big connector in the middle of the firewall, I
think) crosses the firewall, plugs into the ECU and a few other bits inside
the car. I believe the wiring is the same for both Motronic 1.1 and 1.3, so
you might be able to just use the harness in the car and swap the engine and
ECU. 

>I already have a 3.73 lsd.  Also I know the exhaust will
>have to be changed, but is it the whole system, or just the muffler? 

Whole system, I think... The B25 uses twin pipes from the manifold back. The
B27 Was twin pipe into the catalyst (or crossover pipe at least) and then
single pipe back. Given that both engines used the same manifolds on the
same block on the same chassis, you might be able to run with the old eta
exhaust. It will be a bit restrictive, but if you are looking to get on the
road again fast, that might be the answer. You can swap the exhaust out
later. The O2 sensor will have to change, but they should be compatible at
the threads, so no problem there.

>Any responses to any of these would be appreciated, or a link to information,
>or refrence to archived material I missed in my remedial search.
>Ryan-

I believe the only real differences in the engines were:

Speed and pulse sensors (B27, on flywheel) vs. crank position sensor (B25, on
crank pulley).

Different fuel rail pressures (4.5 Bar for the B25 vs. 4.0 Bar for the B27)

Different fuel injector resistances (14 Ohm on the B25 vs. 2 Ohm on the B27)

Different placement of the idle valve.

The B25 engine doesn't have a cold start injector or the thermo/time switch.

The B25 engine has the oil filter/cooler adapter on the block where the
filter just screws on the B27 block... and the oil cooler up front.

The B25 has a sensor for the #6 plug wire to get the injectors in the right
order.

Of this stuff, the only thing that might be a problem is the oil cooler
adapter, but even that should be simple enough to move over or ignore by
mounting the filter on the block just like the B27 engine.

Of course, this is all theory...

Thank you Joe.  These are all worth while responses.

I am not sure then.  I thought the early ETA had just the Motronic system
and the later "Super ETA" had the motronic 1.1 like the B25.  I have an 87
325e with the early system. After thinking about it for a while I might
just buy an E30 325i.  The only reason I considered the swap is that the
body and paint on my car is in good condition, and i have already put
enough money into suspension, brakes, wheels and tires, (which can be
transfered as well as the "is" leather seats I have)so why not just keep
it?  Besides a new car means new problems, but at any rate thanks for the
info.

Ok, I was away from the books while doing my first post, and I made some
errors...

I had the fuel pressures wrong. They are 3 Bar for the B25 and 2.5 Bar for
the B27 engine.

You seem to be right about the ECU issue. Eta engines were plain Motronic 
(35 pin connector) while the "i" engines were Motronic 1.1 (55 pin
connector). The exception is the '88 Eta engine which got Motronic 1.1.

An engine swap might still be a good idea. You need the engine, the ECU, and
the engine harness. The engine harness on the B25 includes the auxiliary
relay block, the connections to the ECU, the OBC, and it all plugs in
through the Main Harness Connector at the firewall. That connector is the
same on '86 and later E30s (physically if not electrically).

If the body, paint, suspension, seats, dash, electricals, and so on are all
good on your car it might make more sense to do the engine swap rather than
buy an "i" and have to swap everything else over or start over with the
replacement of suspension parts.
