this thread is going to make many 323/325/328s disappear. 330 swap is definitely worth it. but i wouldnt do a m3 swap. cuz at the end of the day, the car is not an m3.

After doing a 330 swap, it's not really worth it unless your older engine broke down

Great work, Raymond.
It is very good to know that more powerful and newer (with lower mileage) engines are available for my 323i.
The most astonishing part for me is that the M52 DME can handle the M54 engine without problems. Did I got this right? Have you changed the software?

By the way, did you put an new intake gasket when you swapped intakes? If not, this is what may be causing the vacuum leak.

the only reason you should use the intake manifold of your 323 is if you are not getting one with your 330 motor... otherwise, just use the bigger, more free-flowing manifold.
you will make like 200 hp less if you dont.


[edit]

oops, seems i'm wrong.
raymond put a 323 intake manifold on his 330 motor along with the 323 throttle body. it seems to work.
i have only done 325 to 330 so it was alot easier for me.

raymond, i may have missed it, but what injectors are you using? and what maf? and what software?

i am running on 325 software for now with 325 maf and 325 injectors.
i'm not sure if i want to go the SC route or the NA 330 route.

even more when i spent less then 750cnd on it!

Hey Raymond

Just a question after having this done for some time did you keep the 323 injectors or keep using the 330 ones? Did you emissions tests change at all over the years or are you still passing by great or so so results?

Just completed the swap! Had an engine in my m52 323 that lost compression in 2 cylinders & instead of rebuilding, a member gave me a great deal on a m54 330 engine so I decided to gain a few HP. I unbolted the intake manifold complete with throttle body & bolted in on to the 330. Stayed with the 323 MAF, injectors, wiring harness, headers (aftermarket) exhaust, tranny. Everything matched right up. I am thinking of changing to the 330 rear end as that was part of the deal as well. If you are going to use the 330 headers/exhaust, you will need to do something with the butterfly valve that requires a vacuum line & has a part conected to the intake manifold. I opted to stay with my original and swap to aftermarket exhaust down the road. Anyways, thanks to everyone, I love the extra get up!

awesome, congratulations!
what do u mean "rear end", do you mean the differential? and what about the butterfly valve? is that the valve in the muffler that the golf tee mod takes care of?
why didnt you use the M54 intake manifold, is it because you are coming from a M52TU?
sorry for the questions, just wanna learn more about different ways ppl did this swap.
was this a manual or auto?

It was an auto. I didn't use the 3.0 intake because its drive by wire and mine was not. Didn't want to try to make that work and needed the car to run asap.

actually if you do the m3 swap right your car WILL basically be an m3 only difference would basically be the exterior

no... you are missing suspension components, rear differential, programming, gauges, seats... and maybe other things i missed.

i did a 330 swap, does that make my car a genuine 330? its someting else if you own a genuine m3 or a genuine 330, etc.

you guys should just buy the adapter plate from turner motorsports so you can run the better 330i intake manifold while still utilizing the 323i throttle body and throttle linkage
