E46 owner here, might upgrade in the future.

Hey everyone.

My car is an '03 330 coupe with a MT. I love it and it hasn't been anything but nice to me (knock on wood) aside from a couple (not too important) parts being fixed/replaced.

I was wondering, how reliable is the 335 coupe with a MT? I've heard people rant on and on about the HPFP and I get that.. but more importantly to me, how reliable are the stock twin turbos? At 50k? 80k? 100k? 120k+?
I guess, in short, should I be more concerned with something going wrong with my 330 that has 101k on it? Or an M3/335 with 80k on it? I'm sure my e46 will be less expensive to maintain though. Correct me if I'm wrong.

I'm debating on either an e46 M3 (MT) or the e92 335 (MT).
Thoughts on this comparison?

I know, I know.. the M3 will always be an M3.. blah blah.
Don't get me wrong, I understand.. and might still upgrade to one..
But the 335 isn't a bad competitor at all, even though it's not an M car.

I'm just trying to get some opinions in for now and hear some perspectives other than mine, I'll test drive both of them eventually and see which one I like more!


Thanks!

About a year ago I was in the same predicament as you, almost bought an e46 m3, luckily the deal didnt work out so I went with the 335, im very happy with it. Next to the e92s the e46s are starting to look dated. Parts on my e92 run about the same as the e46 even used parts because for some reason e46 owners put a premium on their used parts. Look up the classified ads in the e90 forums and you will see what i'm talking about.
The 335 might not be an M car but the N54 was used in the 1m and its been proven to be very reliable. The HPFP has a "secret" recall and BMW will replace them free of charge.

I don't have enough stick time in my recently purchased '08 335i but since I still have my '03 325i to compare against (but not for long), I can say for certain that the E46 platform is dated in every conceivable way. Although aesthetics is purely a personal preference, unless you are truly wedded to an E46 in some unique emotional attachment (e.g. first ever car), the majority of the populace will agree the E9x platform does look more modern and sportier overall, with more appeal, proven with it breaking sales records, despite the early criticism of its redesign from some reviewers.

The '08 is out of warranty with 105k on the clock, but I reckon if the turbos go, that gives me the incentive to upgrade to a higher performance pair. Besides, I can do the vast majority of maintenance and upgrades, just like I did with my 325 and my twin turbo 300ZX.

Hehe, ya it is! But I still have it after 22 years, and it only has 89k on it.

We seem to have similar tastes in cars

I didn't want to sell my Z.. but I didn't have the money to maintain it at the time so I let it go. It was a '90 with ~120k on it. It was leaking oil from 5 different places and running on limp mode lol but still got 7.5k for it!

I love the way you sit behind the wheel, it just feels perfect.. not sure how to explain it though ,everything is right where it needs to be!


Anyways, back on topic!

I do notice that there is vastly less participation on E9x forums than the '6ers, and I've rummaged through all the most popular ones. I am assuming that most e9x owners are still on factory warranties or don't dabble much in DIY projects and maintenance themselves, so they don't avail themselves on forums.

Something to keep in mind when contemplating the switch and you prefer to work on it yourself as much as possible.

My Ride: //M3
Had both m3 e46 and my current 335xi........loved them both! Miss the m3, but chose to increase the power of a 335 at a fraction of the cost to upgrade the power on a m3 (supercharge). Pushing about 475 bhp for about $2k versus $10k on m3. Plus having awd is a bonus to put down that power!

E90 biggest concerns are turbos, but at 132k miles mine still function fine!?!? HPFP is not a big deal and quite easy DIY for $300 part.

Wow so much E46 M3 hate in this thread!!! I thought this would be a good thread to chime in on. Im going to look at at 06 330xi with a 100k miles. I wanted read up a little on this platform prior to driving the car.

Curious: what parts did you put together to hit 475 on only a $2k budget?

Tune, downpipes, and meth is under $2k, but 475 might be a bit optimistic. I'd say maybe 425 is closer to the mark.

thats HP at the crank, sorry but running E85 (built into Jb4 tune) along with bolt on's and tune, along with a little help from meth you can push 430 whp....going with bigger turbos and your pushing the 475+ whp
whp mark.

Yea, but bigger turbos will cost you a lot more than $2k.
