Had both an '08 135i w/ N54 and now a '13 135i w/ N55 - the folks here have got it right on the money.

Owned an '08 N54 135i with the Steptronic and currently own an '11 N55 135i with the DCT. N54 uses a throttle body, on the N55 all throttle control is done by the Valvetronic system at the valves, so no throttle body. I'm wondering if most of these cars needed their ECUs to adjust.

Removing the engine cover on the N55 only allows you access to 3 cylinders. N54 vs. N55. But then again the N54 may have down pipes and a larger intercooler too. I am not aware of any delay on my 135is with DCT. But I think either of these cars are a total blast with a stick.Had both an '08 135i w/ N54 and now a '13 135i w/ N55 - the folks here have got it right on the money. Just make sure it has had the recall work done. And agreed, the N55 DEFINITELY sounded a lot cooler. )0 treatment.

Don't rule out a 135i with the N54 engine. Then by pure dumb luck find the car I currently have on a Toyota used car lot.

I really wanted a 2009 135 convertible.

We'll see. Near the top of 2nd gear the N55 started coming back.

My DCT works fine but some people find them a little 'glitchy'. Just to get this straight you've never owned either car, "test drove" some stock unmodified cars and think there's a big difference between stock tune N54 and N55 motors? Finally just the other day we got a chance to line them up, on a closed course with professional drivers...bwahaha.

We raced until the end of 3rd gear so about 110mph or so. This is the first time we ran them. VRSF N54 Downpipes for the 135 and 335 BMW.

Here's my take on differences: Found a coupe in Houston, drove down to buy it, that fell through. Fell through. In to 3rd and the N54 lunged back ahead a few feet.

Thank you for your thoughtful and considered reply.

The '11 is not totally stock now but was when I bought it. Both cars I own(ed) have manual transmissions. This also means two vacuum pumps inside the valve train.

The valve cover on the N54 comes off easier, due to the injector towers and valvetronic system on the N55.
