View Full Version : Is there any particular reason to go for a 95 m3 vs 96-99?

I've developed a semblance of an idea that some people are seeking 95's specifically. IS there any reason for this?
Thanks!

What is the advantage of OBD1 over 2? Less strict emissions policies in certain states?

It doesn't matter. Buy the best car you can find. A well maintained 95 will be better in the long run than a neglected OBD2.
It used to be that OBD1 was easier to mod because all you need is a chip. But now there are several sources that can flash tune an OBD2.

Depends on what you want out of the car. The 95 s50's have a more "square" motor thus making them better for boosted applications. Also because they are OBD-I they have less emissions restrictions.

Some 95s got a tilt wheel.
Some people want 95s so they can do engine swaps and make them street legal (depending on the state).

only 1 O2 sensor on 95 (for ECU)
96+ have 4 (2 for ECU, 2 for measuring effectiveness of cats)

from what i can gather the 97 and later have more displacement and more torque stock. so if you have a newer m3 you can do a manifold swap to the older m50 or s50, with that and adding a header and software you can have a good gain in hp. without forced induction. and if you add a blower later, even bigger gains! so i would go for the newer s52. I did and love it.

moding 101 that's not what were talking about though. Still people specifically go after 95s probably because they don't plan on keeping the motor :stickoutt
When it comes to FI, I think they are both good candidates, and in the lower boost numbers the larger displacement is better. Now OBDII has good tunes readily available but OBDI still tends to be cheaper, and the thicker cylinder walls give it an advantage for big boost (albeit not much). BTW I'm of course not counting the people that bought one because they found a clean well maintained one, even though this is a very good reason.
edit: I don't mean this in a bad way but I don't think anyone cares about LCAB replacement, or I should say it's never been a deciding factor in buying one.

I don't know about everywhere, but in IL a 95 wouldn't even need to take emissions here to be driveable.

What do you mean by "square" motor??

square motors are where bore and stroke have the same ratio. Realistically it's more like close to. Usually, this makes them very good for high revs so if we weren't limited by out crank it could rev pretty high. As far as I know it's the wall thickness that makes the S50s slightly better for boost although that's a bit of an oversimplification.

did the stroke actually change? or did the ratio just become that way from boring out the 3.0 to a 3.2?
btw...did I mention AVUS?!

thanks, I never heard that about what a "square" motor is. you learn something new every day!!

The rods are the same but the stroke is different. As you said, in some cases the ratio could change just from the displacement.

don't forget....the 95 is a ONE YEAR CAR. so well maintained ones are hard to find which IMO will make them collecters items one day.

so they're different cams? for the stroke to change the rods or cam has to change.
Bore changed I'm assuming - hence the different wall thickness.

Technically yes the cams are different. But the specs are very similar except that the S52s are lighter (from being hollow). I believe it is the different crank and pistons, importantly the way the pistons connect to the rods (wrist pin location), which allow them to remain in the right position with the increased stroke. Bore increased a bit, I think .4 or .5mm. The change in displacement is technically less the 2 liters they just rounded up.

I meant crank had to change, not cams. whoops. okay that makes sense now. thanks! good info!
...so maybe this has been covered...but can a s50 run s52 crank and become a stroker? (let the flaming begin here)

I can't believe you would ask this! :stickoutt
Yes and no, though I'm not expert. I just don't see a way you could do it, with out it being an S52. An S50 can't just use an S52 crank because the older pistons' wrist pins can't handle it. So guess what you have to do to make that work :D

early 95's also have weaker spring retainers but when it's all said and done it's all about the maintance record of the car.

95 is the first model year with a timing chain instead of belt, correct?

Yeah I'm not sure what he means. 95s are not the first of anything to have timing chains.

Unless you are willing to travel or have a car shipped, there probably aren't going to be a bunch of m3's for sale in your area. Buy the best car you can find. Anything else can be fixed.
Good ones cost more than crap ones. Somethimes a lot more, and there is a good reason for that.
If you can't afford to pay for the car twice in the first year of ownership, you probably shouldn't buy a 15 year old German sports coupe.

on 1995 you can install higher compression pistons (11.5:1) and raise horsepower close to 300hp, there would be less problems sense its OBD1 and you can chip it.
on a 1996+ You could do the same thing and bring it close to euro spec but you will have hard time with that OBD2 ecu.

A big advantage in Georgia is that you can run a standalone in a 95 / OBDI car. A down side is you absolutely MUST run a cat if you want to pass emissions inspection since it will be a sniffer test. With OBDII you don't have to run a cat if you get some 02 spacers or some other way of keeping the down stream sensors happy.
For a daily I would go with OBDII as there is no shortage of plug in (to the OBDII port) diagnostic equipment that can be very handy when checking the health of the vehicle.
For an all out project car I would go with OBDI.

There actually were no 1996 M3s. All M3s sold in 1996 were 1995 models that were manufactored in 1995 and sold as 1996 models. the 1997 M3s were the first OBD2 3.2 litre engines, As far as the 1995 model year there were 2953 1995 models produced that year. Im not sure how many M3s were made in 1995 and sold in 1996, Tony

If i remember correctly a 3.0L was a bored 2.5 and a 3.2 was a bored 2.8.
