My 06 330i engined pooped out on me and im getting a good deal on a low milage 2010 328i engine. (bye bye extra 50hp). My question is wether everthing like tansmission and everyhing will be compatable with my 06 and if the swap is possible.

Not the trans -you would have to do a bit of coding, the computers are not the same, i think the transmissions are too. The engine should with your wiring, sensors, and computers. The newer motors have a plastic valve cover with a built in cyclone, I'm not sure what differences there are in setting that up. Personally I'd keep the magnesium cover, since they don't break..

Also, keep your 3 stage intake. You will have the same power.. You can't use the 328i dme anyway.

Not sure about the 330i transmission, but the 10 328i has a GM trans

Thanks for your help

Acutally I forgot to mention, i believe the transmission i have now if from like an 07 or 08 328i or 325i. Would that have an impact?

If there is nothing wrong with your current tranny you should just stick with that.

As hassmaschine said, the engine blocks are identical between the 330i/328i and you will not lose any power if you keep the 330i ancillaries. The extra power is all from the coding you currently have. Also, in keeping your current tranny you wouldn't have to worry about coding issues there either.

the 330i/325i E9x had the ZF tranny... they only moved to the GM tranny when they introduced the 328i. the 335i retained the ZF (which is better)...

50HP? Wasn't aware a 330 had 280HP

also You are aware that the only reason the 328 has less power is because of the intake manifold and coding? BMW wanted to widen the gap between the 07 328 and 335 so they detuned it. If you put your 330's stock intake manifold on the 328 N52, you will retain your "50" hp.

[ryryriley]

yeah the 330's only have 25 extra horse

[hassmaschine]

it's not even that he "should" swap everything over - he has to! You can't just swap out the computer, so he has to use everything from the 330i motor on the 328i motor.

basically, you need to take it down to the short block, and swap else over.

I new it was detuned i just never really knew to what degree and what that meant, so thanks. Im going to a shop this weekend to finally get it done and the person doing it knows what theyre doing ill just be an assistant. Im still learning my engine mechanics and stuff so excuse my lack of knowledge. So is this intake bolt on? Is it a simple swap? I tired finding a video that would give me a clue to what the 3 stage intake looks like and how its fits to the n52 but nothing detailed enough.

Yeah you literally take off the 328's and bolt on the 330's. It may require some tuning but you can ask in the N52 section of this forum for more reliable answers. Just to let you know. 328 = 230HP. 330=255 HP. Not too much different. But if you have a 330 manifold then yes definitely install it. If not I'll buy it off ya

[hassmaschine]

take everything off the 330i engine and bolt it to the 328i engine. harness and all. it will work as if you didn't change anything - no, it doesn't need a retune.

Gotcha. I will be trying it.

Thanks for the info! I feel like this is the most helpful section on the forum that i have wrote in.

Please take pics if you do the swap. I was also thinking about doing this if my engine ever went out.

I may be wrong but I think you mean "long block"
Short block is minus head. Long block is with head and valve cover.

Ill try my best to take as many as i can. All im good for is removing the bumper and headlights byond that i have no experience so i might not even know what im taking pictures of. We're gonna try to do it in 2 days

traditionally yes, but these days a short block means a complete engine with no accessories/sensors/wiring, a long block would include everything.

Times change as do definitions.
