Re: All E36s- Which is better - BMW 318iS, BMW 320iM or BMW 325iA?
Engine-wise ..... without any doubt, the 325i's M50 engine is something to die for.
Full case iron block and cylinder head.
They don't make such engines like they used to.
Can mod all you want without any fear of aluminium hydriding / embrittlement, which is the case of today's all-aluminium engine blocks. :verysad:
The M3's and M5's engine block is still cast iron. :evillook:
So are VW/Audi's TC engines - all grey cast iron. :twisted:
Enuf said about cast iron blocks ..... only the true performance models of each marque still retain them.
