Hello everyone,

I have some newbie questions for you all - hopefully someone will pardon my ignorance and answer it!

I am looking to buy a E36 M3, however, the local dealership (not BMW) claims that the S50 and S52 motor is not belt driven. I suspect that they are referring to a timing chain instead? Is this true? What milage should the timing belt/chain be replaced?

They also claimed that the water pump assembly does not have to be replaced, and only the propeller requires replacement - is this also true?

And finally, I've seen posts from searching that on avg the S50-S52 motor makes about 195-210rwhp... I know these cars weren't designed for drag racing, but what do they trap in stock form in the 1/4?

Thank you all!!

Just for future reference, a quicker way to get answers to common questions (like yours) is to use the search function.

And to answer your questions, yes, its a timing chain, not belt. I don't remember if it every is supposed to be replaced.
You need to replace the entire cooling system on any e36 - m3 or not - radiator, expansion tank, water pump (the entire thing), thermostat, thermostat housing, etc.
Stock an e36 m3 does around a 14 second 1/4 mile. Depending on the driver it may be a bit better or a lot worse

I remember reading somewheres that the chain should be replaced at the 200k mile marker, as they will stretch over time, and the tensioner should be even sooner(150k).
Do em both at the same time, as its kindof a PITA
