Wow I feel like an idiot doing this....
I am in the market for a BMW, and no one around me knows anything about them. I have looked on the internet, and cannot find an answer to this question: what the hell do all the abbreviations after the engine code in the car names (the "is" in 325is, for example) mean? I assumed "is" must be some sort of package. I am trying to get the best performance for my limited budget, and I really want to do this right. Thanks.

They made a 2-door 325i in the e30. Also in 1991, they discontinued the 325is, however, the 325i was available with a sport package which essentiall made it a "325is"

For example the old 325E was the ETA model, which also means economical. They had longer stroke (2.7L) motors with more torque and less horsepower for the economical families in germany. If you ever drive one, you'll notice it has better takeoff off the line, but less power in the higher rpm's. They are pretty fun cars.

same with the e30's. in 87 and 88 the 325is' were the only 2door (except for the cabrio) 2.5i e30's and had LSD, sports seats, Mtech1 steering wheel, basketweave wheels, deck spoiler, and the iS aridam(for 87's). in 1990 there was a 2door 325i and a 2door 325is, in 91 there was no 325is but there was a 325i sport which was essentially the same thing as a 325is. i'm very unsure about the way they were in 1989, but i think there were two variants of the 325is both a sport and non sport version since there was no 2door 325i that year.

The first number is the series, or style of the car. 3, 5, 6, 7. 8....etc
The next 2 indicate the engine displacement in liters, such as 30= 3.0 liter.
A 330i would be a 3 series with a 3.0 liter engine.
I= injection
S=Sport
L= Long wheelbase
C= covertible, or Coupe, depending on the application, IC or CI
M= Motorsport

.....that's the main gist of it.

i = sport there are i sedens
is= i w/ gas shocks and limited slip
e = economy
es = e w/ is trim eccept oil cooler
no letter is an e
L = long wheel base
ix or xi (in new models) = all wheel drive
ic = convertable(older model
cic or ci = new convertable or coupe

both 'i' and 'is' had gas shocks, LSD was standard on the 'is' and optional on the 'i', and 325 or 325e/es are ETA's which is the greek letter for "efficiency".

i is NOT sport. It's INJECTION. Trust me.
i agree that it doesnt stand for sport, but do you know of any sources that say it means injection? the 'i' first started appearing with models like the 2002tii which is part of the same generation that was in production when BMW NA first started, so maybe it could stand for international. i honestly have no clue, but i'll take your word for it sense that seems to be the general consensus

Okay, lets break down the basics(for all those non-bmw-tech guys):

i=better then E
is=better then i

325 = 2.5 liter
318= 1.8 liter

a 325iS is nice, with some decent tires, some new shock mounts and maybe a short shifter, you have yourself a good lookin and runnin car.

well if a 325 is a 2.5 then why is my 325e a 2.7? shouldint it be a 327e?
there are many bmw's whose model number doesnt equal displacement. calling the 2.7L ETA a 325 was probably just to save all the aggrivation a salesman would have to face trying to explain that a 325i was a higher model and higher performing car than a 327. 325i and 325is are basically the same exact car except for special options and outside features.
