Ignore sarge927. He's talking cr@p
Yes, you'll need to redo the engine mounts.
You'll also need to install a new wiring loom.
You may need to change the front suspension as the new 6-pot will be heavier than the 4-pot.
You'd need to check as to whether the gearbox is suitable. They don't always match up, so you may need a new box as well. If you do then you may also need a new drive shaft to the rear diff.
What about the radiator? It may need to be moved, or replaced with one from a 6-pot car.
Overall its a pretty big job, but not impossible. Many have done it and succeeded.
BUT - Why replace a 1.8 with a 2 litre? The gains will be marginal for the amount of work required. If you're going to swap out the engine, then at least put in something worth while, like a 2.8, or 3 litre 6-pot. Even go for a 4.4 V8 if you can find one.
Now that WOULD be worth it!

Are you talking about trying to put a different engine in your BMW? Bad idea. There was a day when swapping engines was no problem, but for any car designed and built after 1985 you're going to run into major problems if you try to replace an engine with anything that isn't the exact same model. Cars are now designed to have exactly one type of engine in them, so replacing the engine is usually more costly than buying a new car (maybe not in the case of a BMW, but be prepared to spend $10,000 to do an engine swap, and your car may never run correctly again).

Ive seen 6 cylinders swapped into the 318i four cylinder cars. It works really well because of the light weight of the 318i. It is alot of work however. You will have to fabricate engine mounts, mate up a transmission that fits, and find a wiring harness that is close. It is easier on older cars because of the OBD 1. What year is the car? What year is the engine?

If you're an engineer this is a worthy challenge. I've seen a VR6 Golf engine mated to a Lupo...yes that tiny thing. Best check Performance BMW magazine where you'll find clubs & specialists that do this for a living. If thats what you wants thats what you'll get...at a price!

Don't bother unless your going to go the whole way and fit 2.5 or a midfield 2.7 engine, the cars are cheap, and it's easier just to buy a 320i if you want a 2.0 litre, remember as well as the engine you have to think about uprating gearbox, diff , suspension and brakes. oh and don't forget about about telling your insurance company.

it wont fit cos the engine mounts are going to be in the wrong pklace. Think about the size difference from a 4 to 6 cyclinder engine. call your local BMW dealer and see if they know of anybody who can retrofit it. It is gonna be costly though.

Bad idea. Not meant to be.
