a super eta harness IS motronic 1.1/1.3, its a true plug and play because its from an e28. I has one if you are interestedjustinmd wrote:awesome. So let me just ask the question to be clear. If i get the '88 528e harness, it will fit the monotronic 1.1/1.3 computer and all i should have to do is splice the wires that run from the old harness to the new one?

Wow. I have not seen valves embedded in a piston before.justinmd wrote:Old motor.
It probably got substantially less gas mileage after that.mooseheadm5 wrote:I saw one that flipped around several dozen times, flipped over, punched a hole in the piston with the broken off valve stem, and then lodged sideways in the piston. It also broke several rocker arms and smashed the rocker shafts right out of the head.
how else is he supposed to MAKE valve reliefs?demetk wrote:Wow. I have not seen valves embedded in a piston before.
I just took a look at my computer and do not see a second plug. just the main harness plug (55 pin) with Bosch 0261200153mooseheadm5 wrote:There is no green box (idle control module) for Motronic 1.1/1.3- it is handled by the ECU on the newer stuff.
The 88 528e harness plugs right into the side of the fuse box there like in your picture.
The ECU plug along with a small multi-pin plug feeds through the firewall and plugs into your ECU above the glove box.
The 55 pin connector fit thru the firewall hole in my 84, but it was a bitch. Scraped up the plastic a little on the back side. I didn't have to enlarge the hole though.turbodan wrote:All you need to do to make the 88 harness work is hog out the hole in the firewall where the harness connector pokes through. The 88 has a 55 pin connector which will not fit through the 86 firewall.
should be able to remove the outer plastic shell from the 55-pin connector, fit the connector through the hole, and then reinstall (unless maybe '88 is different from the later ones)turbodan wrote:All you need to do to make the 88 harness work is hog out the hole in the firewall where the harness connector pokes through.

The M20B25's on e30's have an "early" water pump and a "late" water pump. Early has the additional port that points downish. This goes to the reservoir on right side of car. Late does not have the port, but it does have a fastening point for a steel coolant tube that goes across the engine. This tube supports the e30 late radiator which has it's outlet at bottom-right (early rad is bottom left). Late cars have the reservoir on the left side of the car.davintosh wrote: Looks like you have a new water pump... the eta's water pump differs slightly from the i's pump. The eta doesn't have the extra pipe nipple coming off the side. That came up in another thread about putting an i engine in an e28; the e30s and e34s that used that engine had a different coolant expansion tank configuration... From the looks of your engine bay, you must be planning to keep the stock expansion tank; if that extra nipple isn't used in your setup, I suppose it could just be capped off or something.
As for your question about the clutch, any idea how long ago those parts were installed & how many miles are on them? The clutch plate looks to have some life left to it, and should last a while, provided you treat it well. The pressure plate can be hard to judge. When they get old, I'm told it takes more effort to disengage the clutch. Also, if you do use those parts, I'd at least put in a fresh throwout bearing. Not terribly expensive, and would help extend the time until having to pull the transmission again.
Reservoir on the right so early B25 water pump.justinmd wrote:The engine is from an '87 325i and this is what it looked like when I got it. It did have the same water pump as the eta.
