I'm about to buy a friend's rust-free 1972 BMW 2002...but it has no engine or transmission. I was originally thinking I would put the 1.8L & 5-spd out of my '83 E21 320i parts car just to make the car drivable.
If cost were no object I'd swap in an E30 M3 engine or a Downing-Atlanta supercharged Z3 1.9L, but cost is definitley an object, so I'm looking for other good - and relatively cheap - ideas...
LS1.
S50s have been done and they aren't nearly as expensive as an S14.
But seriously, the LS1 would rock.
Rust free, huh? Those are horrible cars, you know. You just as well let me buy it so you don't have to deal with it. 
I would put the E21 M10 engine in it, but I have a turbo manifold for it, too. You can get some pretty reasonable power from them if set up right.
Go with the 320 swap. It will be easy and and it will make a very nice driver, at low cost. You end up with a fun, good looking driver that's cheap to run and operate. Just what a newly wed will need!.If you don't do anything with it, I'd be interest in the '02.
If I go with the 320i engine, would you recommend converting the engine to a carburetor or adapting the 320i's CIS injection to the 2002?
I'm looking for alternatives because I think that the 1983-model, low-hp, CIS-injected 1.8L M10/320i engine might necessitate a whole bunch of work to install and the car would be a slug when it's done.
Be Bold! Be Different!
Touareg V10 TDI FTW! If that doesn't fit use the 3.0L V6 TDI. Either way thats alot of torques and mpg. Don't make me have to be the first...
E21 plus megasquirt plus boost = win

I checked out a ratty 2002 once, the owner was going to stick the engine from a 325i in it. Said something about 170hp. Too bad it was a rusty wreck, photos and hide flaws pretty well.
m42. enough said
That T3 turbo manifold looks like it's very nicely made...
M42 or M44 is fine. either way you are looking at no more weight than stock, and almost 140hp out a more modern engine that requires less maintance.
You can build it up from there. The Downing Atlanta Supercharger can be added later
In reply to John Brown:
I was going to suggest a 13B or Renesis.
the m20 swap is pretty well documented and close to a bolt-in. The weight difference is something like 85 lbs
M42/M44 require some work to the steering to make it work. I think the track rod wants to be in the same place as the oil pan. There are some build logs on 2002faq that cover this swap.
I think an atlas LK5 (vortec 2800) from a Colorado or Canyon would be funny. More Hp and torque than the M10 and it would make BMW purists upset. I doubt the intake would fit as is, not sure about the height of the engine either. If I run across a cheap source for the engine with a 5 speed I would try it.
Bearing in mind that I've thought about all sorts of swaps for my 02 over the years but have always decided that the dual carbureted M10 was too good to remove, I think if I was confronted with an empty engine bay, the temptation to go with a boosted, Megasquirted M10 would be overwhelming. If I was well and truly off my meds, I'd be thinking about an M62, but that's just crazy talk. Some sort of high-revving I4 like the engine from an S2000 would have a certain appeal, but I'm not sure I could stomach the heresy of it all.
I dont remember the engine codes, but id vote for either the 320i engine (and add a turbo later), or the 318is engine (and maybe add a supercharger later). I dont really care for hack job LS1 swaps in cars that dont need that much power. Sometimes stuff like that is cool (like in a completely redone mgb), but in a ratty 2002, probably not.
Mine has a 13b!!!!
The engine codes are hurting my brain.
The boss just bought a cute little 2002. My first question was "so what engine are you going to put in there?". I know his predilections, you see. This is a guy who felt a Westfield needed a turbo. Then, that his turbo Westfield needed methanol injection...
He's going to turbocharge the original engine. After all, there is strong historical precedent. And it's probably the easiest option.
the M10 was the engine that came in the 02 and 320i...
the M42 can in the e30 318is and the early e36 318's The m44 came in the later e36 318's and Ti's and the 1.9 Z3s..
At least BMW engine codes are easier than most Japanese ones
Hi, I'm new here and this is my first post.I was wondering if anyone had ever swapped a 1994 318IS engine into a 2002. Is there anything in particular that i should be aware of during this swap?should the front suspension be upgraded? what about the rear end,should anything be done back there?I have the 2002 and the engine from the 1994 318IS ready and waiting.....any advice from you pros?

Well, they're shorter anyhow 
Let's see, the 540i had an M62. But the M5 had an S62. The M car has an S engine, the normal car has an M engine...
Blackknight, try bmw2002faq.com, there's lots of good specialty info there. Welcome aboard!

+1
I too would go with the 320i swap. The CIS isn't hard to figure out with some research and since you have it you might as well use it until you can add a proper EFI system and MS. Just remember, Weber conversions make the baby Jesus cry.
