"I am selling my old DD only because I found a nice eta recently as a replacement."

I've seen so many ppl use it over on BF.com and have no clue what it stands for.

found the answer on google. this refers to the e30 model BMWs

"The "e" stood for "eta," which is the Greek letter for efficiency and was the theme for the 325e."

Oay - so my 88 325iS which I take it is an E30 would be considered an "eta" ?? Oh whait you said 325e ... mines a 325iS , guess the iS is short for "is Stubborn"

Dont know bout that, BUT if you put a P in front and changed the e to an i - that would be my car, a big ol PITA! lol

I thought it was just a really slow car. When you have to calculate your lap time in ETA, "Estimated Time of Arrival", you know you have a slow car.

Very similar to a "Rolls-Canardly" It Rolls down one hill then Canardly get up the next.

think mine's definitely an eta then although for mine, I think the eta should stand for "Entertaining Thoughts of Abandonment"

Your iS has twice the usable rpm range, the eta motor has a diesel-like redline. More torque though.

Default Nice

From the way I understand it the ETA was BMW's way of being an economy car. The motors were designed to have lots of low end torque but not much HP. The motors also dont go up in rpms much. On the 87 and older the tach was only a 5k and the last year in 88 they went to 6k cause BMW started to experiment with i/e parts which they needed a higher rpm limit tach.

So in that specific year you would have a 2.7 block an i head but e valve train and i pistons. SO the idea is to either swap in the valve train in the 88 or just grab a complete i head and slap it on. Supposedly the theory is its a 2.7i stroker. I am doing this mod in a few months so I have been doing a little bit of research on it. So 327i here I come!

Still not sure why BMW has the displacement as 2.5 and calls it a 325i and a 2.7 a 325 or 325e
