Mein Auto: 2008 335i M-Sport Coupe
Question Track: 335i vs 550i

I'm very confused on the matter, from one person I hear the 550i is better from the other the 335i...

I'm thinking about getting a 335i coupe but I'm afraid I'd be more happy with the 360hp 550i and that reliable motor.

My questions
Would the 335i lose very much power over a course of around 4years with about 15k miles a year and if so about how much?
Does the 335i have better throttle response than the 550i or are they both lifeless?
About how much would it cost to get a 550i to handle like a 335i and what suspension parts would that require.
How much HP could I get out of a 335i without messing with the turbos? Doing things such as cold air intake and exuast changes.
Same question for the 550i.
And the important one which one would be faster around a track such as Luguna Sega, stock? The 335i with better handling or the 550i with more horsepower?

I would give the edge to the 335 given that the car is lighter and should have just about the same horsepower to weight ratio is not better.

The only way to get some real power out of the 335 is to chip it and then you are looking at 60+ hp depending on . For the 550 chipping, exhaust etc will not do too much - at most +20 hp for all.

The 335i is very fun car and lighter. You can boost a HP up exra 70 hP as it could be done on 535. I have only one problem with BMW turbo engine, it's their turbo reliability, because we don't know how those cars would be reliable after 100K. Some people will argue with me on this subject, as saying they have around 100K and don't have any issues, and I would agree with them, because they are a car crazy and were replacing oil every 5,000-10,000 miles, but how about those cars where oil was replaced every 15,000+ miles? That's a question, and could answer in couple years.

Consider an e92 M3 and you get the best of both worlds...reliable 400hp V8 and awesome handling of the smaller and lighter coupe...

I would love a M3 but that's out of my price range. Phlfly, I diffenantly would get either car I get over 100k miles, probably closer to 140k. Would the turbo be to much of a risk knowing that I'm going to spend however much money it takes to make the 550i to handle like the 335i if I do get a 5 series.

I have had a 545 and a 550(sport trans) and now I own a M3. The 5 series is a nice car but it is not a track car. It is much bigger and heavier. There is very little power mods for the 5 series compared to the 3 series.

My 550 is a rocket sled on the highway and handles very well in the curves for a 4000 lb car. But it ain't no track car by any means.

I have a 2008 550i with Dinan Mass Air Intake, Dinan Stage III software upgrade and Dinan Throttle Body. Those mods put me right around 392hp and 385tq. I have clocked my best 0-60 at 4.9 but the real power is 60-170mph. You can definitely get a better power to weight ratio, even than mine with a 335i with jb4 or the like. I've seen those hit 60 with a great start around 4 flat. Most start in 2nd for that run since starting in 1st usually burns up the tires and cant get the power down effectively. Pretty ridiculous... They are also lighter and a little better balanced around a track.

I'd say this, for me, 550i with my simple mods is heavenly and a true pleasure to drive every single day. I've had it on Mid-Ohio and its poised and a rocketship. That all said, if you really want to track it regularly, the 335i IMO would be better pretty much all around.

To answer your question more specifically about what to do to a 550i to get it to handle like a 335i, the answer is its impossible to have them handle the same as their wheelbases and weight distributions are different. What you could do to make them similar would be start with the 550i Sport (2008-2010) (then the suspension is already more firm, had millions in factory r&d and is well balanced and made specifically for that car, and a much better base to start from), upgrade the sway bars front and rear and the front and rear strut tower supports, then strip everything you can out of the car when on the track to drop some weight. Get some sticky tires and you'll be able to handle with the best of them. You could go as far as to get an adjustable coil-over suspension and it would certainly be track ready and handle on rails but thats a few thousand minimum ($4k installed) to get a decent+ setup.

If I were to spend $4k on mine for handling, i'd ditch the coil-overs and instead do new front and rear swaybars/tower supports, sticky tires and a big brake kit. If you're a good driver, that will be more beneficial than coil-overs and cost about the same. If you can wait an extra 20-50 feet to brake into corners and understand the suspension's roll, you can push that e60 through the corners real well and its super fun! Just my humble opinion.

OP, this sums it up...the 5series aint a track car. If you are concerned about the cost of the initial investment in buying the car, what about the maintenance? On top of that, you are going to track it? You'll spend less overall on purchasing an M3 that's set up for track work right out of the box and has a fairly reliable engine vs. a 335 that will have ongoing carbon buildup, injector, turbo, and fuel pump issues. You'll still have to buy suspension and power upgrades. A cheap BMW is more expensive than an expensive BMW!

This helps out a lot, but on the other hand I wouldn't have to spend anything to get the 335i to handle good. Do yout think it would be worth the risk off the turbos giving out and do you think the 335i's engine would lose power in the motor after putting around 70k miles and 4 more years of driving on an already 60k miles car?

This is a big question, as I said in my previous post. You do whenever on both cars but 335 will handle better on track due the weight.
But as someone mention go buy M3. But if you want a track car then E46 M3 is best car ever from BMW. I can argue on this topic forever and will win anyway. I had one and it was best car ever I have ever owned.

OP, go to N54tech.com and look at what guys are doing to the twin turbo engine that is in the 335, an in many other platforms as well.

If you are against tuning the car, then forget about track performance. The 335 will do better than a 550, but what's the point.

The two cars are radically different. One is a V8 sedan, great for the highway and long cruises. Few cars do better there. The 335 is a competent all round car, handles great. But is is much smaller, lighter, more track ready if you wanted to mod it.

Keep doing your research and decide what you really want.

As a teaser, some 335s put down over 500 hp and close to 600 lbs torque. They beat M3s, M5s, even hang with GT-Rs. All for a few thousand in mods.It's the ultimate sleeper racer. But again, decide what is important to you.

Well how much more wear would chipping the car to as apposed to leaving it stock? Again I'm going to have to live with this car for around 4 years and t will end up having around 140k or so miles before it's sold
