Default S50 vs S52

I searched and could not find what I was looking for... So sorry if this is a repost!

What are the pros and cons of the S50 and S52? This is a very broad question, but I would like to know more...

Gas mileage?
Horsepower was the same...
Mod potential?
Low-end torque?
All torque?
Reliability?
Weight?
And anything else...
I am trying to buy an E36 and am wondering if I should wait to afford a 1996 vs. a 1995...

Thanks!

Well from what I have read on the forums i will try to full some of the questions.

Gas - N/a
Hp - Same at flywheel and like 20+ more at wheels for s52
Mod potential - S50 really easy to mod because of OBDI, S52 a little harder to mod because of OBDII.
Low-end torque - It maybe the same or a little more like in Hp...
All Torque - N/a
Reliaility - S50 older has some probs with some pumps S52 don't know
Weight - N/a


And good luck.....

Oh and once you get your M let get a meet going.

That was basically what I was expecting... But I don't know if I want to wait to gain the funds in order to afford a 1996+.
And WTH is OBD?
Thanks!

stock for stock....expect the s52 to have a lower, better torque curve and rating b/c of the bore from 3.0 to 3.2.... and a better overall feeling of power.... and also, combined w/ the 3.23 diff found on the 96+ models... it is faster for sure...

the '95 3.0 time to 60 is around 6.0 secs... w/ a 1/4 of 14.5-15...

'96+ 3.2 has a 5.5 0-60 w/ a 13.9-14.5 1/4...

modability...s50 for sure, you can pump out wellll over 300 hp to the crank w/ the s50...s52 it ends a little after 300 cammed and everything.... both n/a that is...boost...well..lol...very endless possibilties...

the s52 is a tad smoother running too w/ the updgraded valve train...

my dad has a '95 and his is stock and always says how my car has a bit more power than his....

OBD I and OBD II is just a computer system that helps the engine out..... and makes it run. I think.....

OBD=On Board Diagnostics. Just a standard that car manufactures have to adhere to.

No offense, but how do you have over 2200 posts and don't know the answer to this?

its just strange that he has so many posts without any knowledge. And being on the e46 forum doesnt mean he wouldnt have any access to obd2 info, he should know that e46s also have obd2.

By the way...96+ m3s have nowhere near to 20rwhp more than 95 m3s. Obd2 cars have a slight advantage in torque due to different headers.

Obd1 is easier to modify partially because of the obd, but also due to the restrictions in place especially in the 95 m3 exhaust system.

I heard somewhere that the S52 also has a different intake manifold which really affects the torque curve more than anything else.

one again....bigger engine = more power... our 3.2's are underrated... people are putting 212 hp to the wheels... do the math w/ 18% drivetrain loss and it comes out to more than 240 crank hp...
