The M60? There's a lot of 1993-95 e31/e32/e34/e38 M60(B30) & M60(B40) owners here in the USA that had the Nikasil issues where they had to get replacement engines or warranties extended to 100K miles/6 years from BMW that may disagree with how great the M60 engine was.

And many BMW owners that had models with the venerable M30 engine may take umbrage with your statement. BMW squeezed almost 30 years of life outta the M30 engine...whereas the engines since then have had a much shorter life-span....there's been some great modern BMW engines since...but none the long-lived life of the M30.

Just a thought...not an argument.

BTW...N62B44 engine with 109k ...but I'm only 3 weeks into ownership...so I have my fingers crossed for a good run...I hope time is on my side.

The only problem I've heard and fixed on mine already is the chain guides after 200000 km.

IMO, the list of best BMW engines starts with the six cylinders, goes to the four cylinders, follows with the twelve cylinders, and ends with the eight cylinder models. If we have to include the ten cylinder models I would put them with the eight cylinder models. The exception would be the M20B27 eta engine, a six cylinder masquerading as a four. All IMO.

M60 is capable for 650 HP, with no problems so far, a friend of mine built a 0,9 bar supercharged M60 with 4.6 l displacement in E36 - bored and stroked, the only forged non-OEM parts he used were forged pistons for 8,5:1 compression rate, even the rod bearings are stock. The car has done 6000 km so far, mostly on race tracks and there were no single issue with the engine, but in this 6000 km he replaced 1 gearbox, 2 diffs, 2 sets of stock driveshafts and 1 propshaft, now he got a heavy duty diff, custom made drive shafts and very stable propshaft installed, also the diff mounting and the floor were reinforced. The S6S Gearbox is also still stock, so he has to shift carefully to save the synchromeshs, but the main shaft bearing seem to be fine even with this kind of power and torque (790 Nm with agressive maping)

He's currently building 2 other supercharged M60 - one of them is ready to be installed in to E36 cabrio, and the other one goes in to 99 Z3 Coupe.

So what Nikasil issues you're talking about? Not to mention, even not the all M60 engines had nikasil coating of cylinder walls. I also know a guy in Austria, who built a ITB 4,5l M60, which revvs up to 7,7 rpm, using full forged internals, this engine showed 440-450 on engine dyno. He got it officially installed and registered in Austria and this engine seem to be more reliable, than S62 with less power and more displacement.

M60 (and also M50) heads have e very good flow rates, which are for sure not comparable with flow rates of SOHC heads, of the engines, which could be more reliable in BMW's history.

M50 as a 2,5 l version with iron cast block is capable of 600 hp on stock internals (exept again for pistons) and such a set up will be reliable for at least km 40-50k.

So that were my reasons to call these 2 engines the best BMW engines ever IMO.
