I want a 3 series, especially m340i, but all the ones in my area are rebranded titles or very high mileage or huge seller markups and im now leaning towards b48? Am I missing out a lot? Will I regret my decision? Is it worth the extra 10-15k$?
If you want to experience the b58 if honestly say consider the 540i. When I was in the market they were going for similar prices as 330s. I have one and it’s quite the monster compared to my friend’s 330.
The B48 is a punchy engine. Grunts and torquey down low and super smooth about putting the power down. It’s not overwhelmingly quick but there’s this to chew on…
The B48 330i msport and the B58 340i each have the same 155mph nanny on board.
Can confirm, the 155mph limiter in the B48 works. Power to spare too.
I have the B48 in the 135i, it’s rapid in the one series but I’m unsure how that will transfer to a larger car! Probably plenty fast enough for every day driving but if you want that extra punch the B58 would be ideal.
I got a 320i b48 and not disapppointed. Did a stage 1 and running 288HP
Drove an X3 m40i for 2 weeks, it wasn’t as fast as I expected. My friend bought an X4 xDrive 30 and I am very pleasantly surprised with the quickness. Now if you’re making the compromise of a 3 series for fun, I would do the B58 for sure.
I own a f82 m4 so s55 engine I previously had a g20 330i stage 2 daily drive they are the same car except suspension you won’t even notice now of course if your drag racing and counting times etc it would be a big deal, but my 330i kept up with and would beat 5.0s when I got up to stage 2 power was amazing tons of fun. I always regretted not getting a 340i when I got my 330i for years that’s why I kept doing mods and upping the power, but after getting a m4 I realize it was kind of a grass is always greener on the other side type thing not too much of a difference unless your drag racing or tracking the car. To sum it up buy the m340i if you have money more platform to work on and you won’t spend every day wondering if you should have got a m340i. If money is tighter and a issue then get a 330i. Too me and this is no shot at you but it looks like money is a factor as your looking at rebranded and high Mile cars which I don’t recommend. Also one more question why not get a m4 they are cheaper then a m340i?
If you go with a 330i, stick with RWD and get one with the M-Sport Package. Test one out and put the drive mode and transmission into Sport; you may find that it meets your needs.
I second the sentiment on looking into a G30 540i if you’re set on a B58.
It’s hardly a let down, sure it may not be as good as a B58, because it is essentially a B58 with 2 cylinders cut off, so it isn’t as powerful.
The B48 is a brilliant engine, very reliable and durable and has been proven to be a good tuning platform in recent times. There was one person who achieved over 450whp on the stock B48 internals (G20 330i), he reckons it can go up to 550-600whp, so it’s easily as strong as an SR20DET, 4G63 or an EA888 in terms of strength.
