I want one with a GM LS platform V8 and six speed manual. Truth is, you can fit just about anything with enough time and money. I have seen Japanese, American and German engined versions of these cars. Probably the biggest questions are your budget and skill level...

Best answer ever but yeah you have alot of options.

The easiest is the m50 or m52its not much more power but the after market support is pretty good.making it a good platform to build on

the m62b44 will work you can find the mounts for this swap online just do a Google search for it. Its also a fairly common swap. And those engines are very affordable.IMHO this is the best swap for these cars.

Other swaps I've seen are the s52 and s54 swaps. Way more work and money, and Toyota 1jz swap. You can also do the ls1 t56 swa. I think the mounts for that swap are also available online.

The m20 is also a good engine it maybe single cam but it does have after market support. Schrick sells cams for it. And there are alot of Turbo builds out there you can follow. Although I'm not much of a Turbo fan

The M70 (fitted to Andy's touring) is pretty much two M20's on a common crank.

Go Big or Go Home

It would be cheaper and more practical to sell your 525 and buy yourself a 540 or 535 , its within reach of your budget

M62b44 swap is the best bang for buck choice and can be done for that much. I've seen them sell as cheap as 500.00 the after market hasn't caught on to their potential. But it makes the most sense, you not only get 280hp but you also lose weight upfront. The m62 is a very lightweight engine its lighter than a Honda f20 engine from a s2000.

But then yould have to deal with a car that yould have to sort out. And it would have e a nisil engine. Plus finding a manual one is gonna be difficult. The insurance might also be more

mechanical issues are a lot better than the inevitable electrical gremlins that ALWAYS come with engine swaps. your M20 engined E34 was not sold alongside the M60, and usually the wiring adaptors are different.

and the nikisil "issue" you are talking about was a problem from almost 20 years ago when these cars were made. it might be on Wikipedia. but its hype. nothing to worry about. all affected engines were replaced under warrenty or would have well and truely died by now if they were going to at all.

if your engine is still running and you have a nikasil block, you don't need to worry about it anymore. the problem would have showed up by 50,000 miles. the fuel is too clean in the US for it to be an issue at this point. it would have been the fuel from about 15 years ago that had a high enough lead content to eat through the nikasil components and cause damage. so if it hasn't happened by now, it won't happen. at least not with US fuel

the Nikasil block is the biggest boogeyman put out there on this series when they can't find anything else wrong with the engine.

The dealership told me that an engine hesitation and low idle I had in my e34 with 175k was from the Nikasil block. then I changed the spark plugs and the engine runs like brand new now.

Otherwise, I have to echo some of the sentiments here and just recommend getting a 540i for that kind of power instead of dealing the electrical gremlins that an engine swap is going to create, unless you enjoy the process of problem solving.

I have heard of one person putting a Chevy V-8s in 94 530i's but I cannot confirm that rumor. It's probably on some thread somewhere.

But on the broader view of things, why would you need a six speed for anything but track racing or driving 120 mph on the Autobahn?

It isn't lead that is the problem, it was sulfer content that caused problems for the nikasil coatings. You are correct, it is no longer an issue in fact nikasil coatings are still used today, my sled has freshly re-coated cylinders, about $200 each to refinish.

I wish my 535 had a six speed. 1-5 for performance, 6 to get the rpm's down on the highway for economy. Or, like my six speed truck, 1 for low speed grunt work, 2-6 for road duty. Seems like a good balance for most vehicles. I do not understand the new 8 speed automatics though. That seems like it would be really busy.

I don't know, my 530i is at about 2000 RPM in 5th gear at about 60 mph and gets me about 28 mpg. Every once in a while, I'll juice it on a lonely highway but I frankly can't afford to get a ticket and even more, I can't afford to have my insurance jacked after that ticket.

I'm still recovering from the 100 mph ticket I got in my 1985 535i in Tennessee from years and years ago. I'm only lucky my radar detector went off all of a sudden and I was able to get down from 120 mph, before he got me.

"Do you know how fast you were runnin', boy?"

You don't wanna hear a cop say that.

You bring back some bad memories I heard that line only it was followed by "you have the right to remain silent..." I was going 100+ in a 40 zone in Florida that's jail.

Just find another M20 and drop it in then That would be the easiest and cheapest route.

If there is nothing wrong with the engine in your car currently, I would keep driving it and not worry. If well cared for that engine could still last for years.

M20 performance parts are cheaper than m50. And the m20 is a pretty good engine. IMHO though if I were doing a swap I'd go to a m62
