E28 SETA Build

Well the engine will be out already while swapping the trans.  The only difference is the 6hp?  Are all of the sensors and other stuff the same?

The only difference in sensors are what Motronic 1.1 vs 1.0 requires. I don't remember exactly what is added if anything but the crank position sensor is moved to the front of the block vs inside the transmission. This website outlines a good history of the differences for ETA's if you are curious.

Good info, so it's a different computer and harness then.  So what parts combo is an "i stroker"

A regular old eta bottom end and 885 head if i am correct. Or if you want high compression you use the seta bottom end.

[RamRod E28]

So swap heads from the super eta and keep the regular eta bottom end?

[jc43089]

The seta already has an 885 head.  Is the cam different?

[Rowleym]

Paging snap.

[RamRod E28]

SNAP!!! also cyoung I looked at the trans and the 2 holes for the old m20 crank sensor are filled in and will have to be drilled out if im gonna stay with the old m20

Yes SETA's have the 885 head but it has the eta cam and single valve springs. Read this page if you wanna know all about 2.7i or "e to i" builds

The other problem I ran into last night while talking to Mike was that his transmission bell housing has to have the provisions for the speed and reference sensors for motronic 1 which use the flywheel. The bell housing needs those two holes on the drivers side as circled below. I don't think it will have those holes though because the SETA has motronic 1.1 which moved those sensors to the crank pully.

So the options for your manual swap are:

• Swap G260 onto the ETA along with the motronic 1.1 harness and required sensors (which would included fixing your harness)
• Swap Complete SETA drive line into the car (again requiring fixing the harness)
• Find a compatible G260 from 1987 or earlier 528e/325e

Mr Menard and I will see what's what once we pull the 84 drivetrain. I'm sure we can figure something out!!!

[jc43089]

They had to make it different for one year...  This probably also means that the flywheel from the seta doesn't have the toothed ring either.  Ideally it would be nice to leave the eta in and build a 2.8i from the seta to swap in in the future.

Also before you take the parts car down from the stands, get the shifter linkage out, the carrier and shift lever/rubber boot and the wire that goes through it can just come out as one piece.  The clutch master needs to come out too.  Just mentioning what I forgot while we were working on it.

we also need the pedal box as well kind sir so idk what im gonna do about the brakes to get it out lol

I am here.

You should try to get as much of that stuff out as you can before next Tuesday, then we can get started on the good car then.  I'd be up for starting pretty early.  With a long day we may be close to getting it done.  Probably going to end up swapping everything from the '88 into the '84.  Any other option will need a bunch of different parts/time.  There wasn't much bad on the harness.  And the '88 engine seems like it was taken care of decently.

[jc43089]

So after a bit of thinking today this might be really simple.

Swap seta and manual into car using seta harness etc.

In the future find an i cam and springs to swap in to make it an "i stroker"  Am I missing something or is it that simple?  What pistons are ideal?  And the head could also be shaved and worked over as a "next winter" project to raise compression ratio and flow a bit.

Also you will need the bracket welded to the inside of the transmission tunnel that supports the end opposite of the transmission of the shifter plate. This is what I need to fabricate for my car since previous owner removed it and I forgot to take it off my last E28 before scrapping

Anyone else chime in about this i cam swap?

[jc43089]

Did some reading on Strictlyeta.net and the future cam/spring swap is the way to go.  Even better if you can find a hotter than stock cam.  Engine swap coming to a garage near you on Tuesday!  I think with an early start we can get most of it done, I have some leftover seals/shifter parts and stuff from other builds that I will bring in case we need it.
