Ok now, in these E30's, what is the difference?

325, 325I, 325IS, and 325E.

If I wanted to buy one that is going to be the most reliable mechanically, which one would I look at buying? Cause the next one I'm looking at getting I want to turn into a sleeper, so I want to know which engine will hold up the best, I'm not going to be overdoing it or anything, just a little tune up to make bit faster, just want to know which will hold up better. Thanks in advance.

325i/is differences:

suspension (springs, sways..nothing that cant be changed/added)
the I (2 and 4 door) have fold out rear windows, the iS doesnt
the lip and spoiler are there

its the same for e/ES i think...but all the stuff can be changed except the rear windows

You're wrong on the fold-out windows. They were around only in 88 I believe, and were available on both models.

The i/is have the M20B25, which is the 2.5l I6. It is a relatively high-revving engine. This model was from 87-91.

The e/es have the M20B27, which is the 2.7l I6. It was designed to give 6cyl power but still be able to keep BMW's CAFE averages down. It comes in 2 different states of tune, the eta and the super eta. Research more for details.

Reliability-wise, the etas are usually not driven as hard (they don't invite it as much) and therefore live longer. That said, the condition of the particular car you are looking at is more important than the model. The etas were discontinued in 88 so I'd say look for an 89-91 325is. Newest bodystyle, more fun engine, etc.

Hope that helped!

In 1988, the 325 eta was called the "super e". They used different pistons than both "E" motors and "I" motors. It also used an "I" head with larger ports, and a 7 Journal- Bearing "e" cam. The ECU was unique to the super "e". It used a full "i" exhaust.... Basically rated from the factory @130HP and had a higher readline.

I recommend going with an '89 325i... elliposid headlights with new plastic bumpers.

You can find a lo t on www.lukasbmw.com ....and very nicely described what to look for when you go to buy a bmw.

I do not know if You buy 2 dr 325E but I heard that those cars nowdays break down like crazy..?????

If you take a look on those E30 on ebay many of them have more then 200k miles and they still run...

Now the question is which one will not give to pay for repairs and all that but if you want better look then those 89 - 91 are nice and a bit more expensive (depends on condition).

To make it easier for you I just copied this from lukasbmw ...

THE DIFFERENT MODELS

E30's were sold in the USA from 1984-1991 (1993 for convertibles). There were 2 door's, 4 door's and convertibles. Engines and options varied. Below is a quick rundown of the models.

M3 (1987-1991)
The legendary E30. Powered by a 2.3 inline 4 (s14) that put out 192 horsepower, 166 lb/ft of torque, and redlined at a lofty 7,100 RPM. The M3 is easily recognized by it's flared fenders, deep front spoiler, ground effects, bulky trunk, and rear wing.

325i/is/ (1987-1991)
Powered by a 2.5 inline 6 (m20b25) that produced 168 horsepower, 164 lbs/ft of torque, and a 6,500 redline. The "is" model came fully loaded with leather, heated seats, OBC, sports suspension, air conditioning, premium sound, power windows, power locks, power mirrors, and "basketweave" wheels. These options were also available on the "I" but you had to order them. The "IS" models can be recognized by their deep front spoiler, rear decklid "heckspoiler" and the 14" "basketweave" rims

325i Convertible (1987-1993)
Obviously the convertible had a removable roof. It shared the same engine as the 325i (m20b25). Like the "I", you had to order the options you wanted. The Convertible was equipped with E30 M3 front seats (only difference between E30 M3 front seats and regular front E30 seats is the stitching pattern), and a different rear seats to accommodate the power top.

325ix (1988-1991)
The 325ix was the "four wheel drive" E30. It had the same 2.5 inline 6 found in the order 325i models (m20b25). The IX came with 15" basketweave rims, special side skirts, and small fender flares. Other options varied.

325 (1986-1988)
The 325 was the base model from 1986-1988. It came with the 2.7 ETA engine (m20b27). These cars were usually stripped of options and some even came without sunroofs! In the final year of production (1988), the car came with the "Super ETA" engine. The "Super ETA" had the 2.7 "ETA" block, but came with different pistons, an "I" head. and an "I" exhaust. The rev limit was raised to 5,500, and horsepower went up to 127.

325e/es (1984-1986)
Powered by a 2.7 inline 6 (m20b27) that produced 121 horsepower, 174 lbs/ft of torque, and a 4,800 redline. The "ETA" engine was designed for the economy not for power. The "es" model came fully loaded with leather, sports suspension, air conditioning, premium sound, power mirrors, power windows, power locks, and "basketweave" wheels. These options were also available on the "E" but you had to order them. The "ES" models can be recognized by their deep front spoiler, rear decklid "heckspoiler" and the 14" "basketweave" rims.

318is (1990-1991)
The 318is came with a high revving 16 valve 1.8 liter inline 4 (m42b18) producing 136 horsepower and 128 lbs/ft of torque. The car was advertised as a modern day 2002. Although most people opted for the 325is, the 318is provided a bundle of fun for a great price. (NOTE that the 318is came with the m42b18 engine and the 318i came with the m40b18 engine).

318i (1990-1991)
The base model E30 in the 90's was powered by a 1.8 liter inline 4 (m40b18) that produced 115 horsepower and 122 lbs/ft of torque. Options varied. A 318i cabrio was even available for a while.

318i (1984-1985)
The 318i was powered by the 1.8 (m10b18) inline 4. The engine produced 101 horsepower at 5,800 RPM. Needless to say it was slow. Options were limited, and the car only survived for two years in the US market.
