Trying to summarize Super eta (S-eta) stroker build info.

[nando]

you already have the 60-2 crank trigger wheel and your thermostat housing is the same

flash pretty much nailed it

[reelizmpro]

No and no. Super ETA is already Motronic 1.1, the swap is as easy as swapping the DME. No need to change the thermostat housing either. Some housings (etas) have sensors there, some are plugged and some don't have any ports at all.

[Flash]

The difference between the super eta harmonic balancer and the 325i harmonic balancer is that the pulley size is a little different, and the 325i is heavier, just by a little. On the backside of the balancer the weight goes about 4mm to the teeth, and the super eta was about half way to the teeth from the center of the balancer....if that makes any sense.
You would never know unless you had both side by side however since out of the corner of your eye it appears to be the same.
You dont need to change it really, the balancer is just a function of the weight of the rotating assembly, and of course...pulley size to denote slowing down or speeding up every accessory.

It is like the well of knowledge has opened up...I drinketh abundantly.

Last question (for now). This deals with sourcing parts form a donor.

If pulling the necessary parts from the donor vehicle, is it accurate to say that if one pulls the cylinder head and everything in front of/on top of it (all the way out to the airbox) as well as all lines/hoses that attach to the head or anything bolted above it, I should have all of the necessary underhood parts to build the stroker on a super eta?

On top of that, the cluster, DME, and alternator are needed. The "i" brake booster would be a plus, as would be the radiator.

Anything else NEEDED from the donor? All of the parts are being pulled today, but I am putting eyes on the donor when I pick up the parts, just to be sure that they got every line and hose that I might need.

I'm not certain what you are asking here If you have a donor car that has everyhting, why would you be worry about what you ahve and dont have? couldnt you just take it as you go along?

I think that is a pretty safe assumption.

Sorry, I should have specified...the donor is in a junk yard. I tried to buy the whole car, but they wanted too much.

Good Answers!

Too bad you're in West V. I have a complete rebuilt m20 top end I'd sell ya.

I sourced an "i" top end with 135K for very cheap. I plan to examine what needs rebuilt and go from there. I am in no hurry.

I also get the cluster, DME (not sure yet if it is a 153 or 173), "i" alternator, some A pillar tweeters, and a 'vert front sway bar. I may also grab a rear exhaust section (cut right after the factory coupling, for some dumb reason).

[phenryiv1]

What all I got:

[Flash]

All you needed what the list i provided, 10 parts, not the brake booster, alternator, or anything else.

A lot of that was thrown in as part of the deal.

I got a 153 with the swap package. The yard offered me a 380 in its place. No 173s available.

Should (can) I run the 380 in the Seta build?
