When you were looking for your motor, what did you check for besides mileage? What are some tips in finding a good used motor? Check for leaks etc...?

the DME was a ***** to reprogram.

how much of a difference in performance do you notice going from the 323 to the 330 engine? given that you've had both now.

My cousine has a 323i (one of the last ones in production) and I have a 330i zhp. I feel like the difference is pretty immense... But I am looking to get rid of my engine and buying a S54. I would offer my M54 but it has 106,000 miles on it. It does get 31 mpg on highway still I don't know how.

Post as detailed of a write-up as possible in the DIY section and link it up here. I'd definitely like to see the pictures and hear what it took!

Ok well Im at work now so cant post any pictures but Ill get to it either tonight or tomorrow afternoon...

VonGeiss - The motor pulls way harder 55 hp does make a big difference...

ToddInLou - Its guys like you that make me want to post this info. You need NO electronics from the 330 thats right NONE. Even a BMW tech told me im going to have to flash my DME and all kinda crap. I didnt do any of that. They are the same motor I had no plugs left over or anything. But like I said more details to come tomorrow...
