Hi Bro,

Have you found any difference between 320i/328i engine except the exhaust? I tried to search a lot but came out the result that they're the same except the exhaust.

Do you think a Tuned 320i = Tuned 328i?

So I've done some research just looking up at the BMWparts and it shows me the following ;

Both 320i and 328i engine code is N20B2000
Both Compression Ratio, Bore Stoke is the same.

Both items are sharing the same part number
Engine Block SAME
Intake Manifolds are the SAME
Exhaust Manifold (Turbo) SAME
Cylinder Head SAME
VANOS Valve SAME
Vacumn Control + Pump SAME
Throttle Body SAME
Intake Airbox SAME

As you can see, Kelleners has already made a tune specifically for the 320i and 328i respectively. But what I do not understand is how come BMW and Kelleners actually made 2 different tunes if the foundation(components) of the vehicle is the same.

I can't wait till other tuners are able to find more information to unlock the potential of the N20B.

Would you now consider to buy a 320i or a 328i if both models are available in your country?
