Please don't take this the wrong way. I love creative thinking. I have a 328i. Would love a little more power. But if you want turbo sell the car and buy a 335. Buy used. Take out a loan. The idea that you can rely on an after-market technology that already has its own issues vs buying the turbo BMW made is just a bad idea to me. Way more expensive. You can mod the 328 to death, or just buy the much faster version of the exact same car. I still believe at some point the 3-stage intake manifold and reflash might become a reality for existing 328's, but until then, I'm enjoying my performance exhaust and just how amazing the 328 is as is. Good luck. Hope you find what you're looking for.

well half of your dream has come true. there might only be 2-stage intakes for our 328i's but there is the LETmotorsports tune that squeezes a significant amount of hp and tq out, not to mention how much smoother the engine becomes. I have it and its a night and day difference from a stock 328.

I think a small S/C kit would be a lot more practical... different than a 335i so at least we wouldn't be getting the same stuff as the N54. I'd much rather see a more reliable 40-50hp gain than an over stressed car trying to compete with 335i numbers, not to mention I don't see many of us wanting for fork out more than $2 grand for something like this or else we could probably carmax our own cars and just buy a used 335i.


oh and yes... what Quicksilver said about the tune... I love mine!

3 stage intake manifold would be a dream come true

Thanks guys. Good advice. I also completely forgot to mention that with a turbo after-market kit on a 328i, I believe you have to upgrade the transmission, brakes and maybe a few other things to deal with the added stress of the turbo. The dollars really start adding up. If somebody already wrote this, slap me. It's early.

e91. You mean a station wagon? No offense, I applaud your tenacity. But you want to turbo a station wagon? No. No. No!!! Sure it'd be fun to have a turbo on a station wagon, but it's just wrong. Keep that practical wagon and buy a used 335. You deserve to have practicality and fun, but I don't think you're going to get it in one package. Station wagons, no matter how upscale they might be, are still station wagons. Maybe sell that sucker and get the new BMW coupe/SUV? Good luck. You got mocksey, I'll give you that.

you do realize that in europe they make e91 335i and that wagons outsell the rest of the model linups 3/1? I've even seen some cool stuff on the m5 (touring) wagons.

asking for a 335i wagon isn't out of the question but I think BMW knows it wouldn't sell enough out here in the US... they should still offer to make them if ordered though. Id totally rock one too and I'm 27 w/ no kids.

Thanks for your support and enthousiasm.

I'll sign you up for

BTW, I am originally from Europe and quite accustomed to wagons. Makes no sense to me that you would forgo trunk space and the comfort of a 5th door. SUV just not my thing and not accepted on track. To each his own.

Agreed. What people fail to realize is that BMW produces many more naturally-aspirated 3'ers with the 3.0L inline 6 than they do FI engined cars, I'm sure the ratio would diminish the 335 to an even smaller percentage outside of North America. In addition to that, there are, and will be alot of these cars purchased used by people who down the road may want to add some pep that's more significant than an intake, exhaust and tune can accomplish. So for people who say the market doesn't exist, not everyone can get a 335i the first time around or be able to take the hit with trading in their NA car in exchange for one. Granted the timing may be too soon, but I'm sure we'll see some kind of offering on the market later on.

Given the lack of options from both BMW and Audi in North America, looks like you and I need to go to Mercedes and see if we can work out a deal to order a pair of E63 wagons

Yep, Supercharger would be the way to go in my opinion as well


And I would kill for a E91 335

Heard back from Sean @ vf to acknowledge the message.

Just to be precise, let me clarify based on his reponse that we are talking about a "supercharger", not a "turbo". They do not develop turbos for BMWs.
A supercharger is still forced induction but powered by the crankshaft, not an exhaust turbine (turbo). See edit and wikipedia link on first post.

Frankly, I did not know the difference before and equated turbo to forced induction. Silly me. I am glad I learned something today!!!! Sean, if you read this, thanks a bunch. I may be a bit better with jet engines.

Stay tuned. Will see what comes out of this.

I wouldn't mind a centrifugal unit, but a twin screw would have a totally different power delivery and would be tops in my book.

On a side note, and not to sound like a complete FI noob. Has anyone considered attempting to run a retrofitted 335 turbo manifold on a N52 328 with a 335 tune and 2 small aftermarket turbos? or a 335 turbo manifold with custom single turbo and custom tune? Just an idea for the courageous.

Disclaimer: I have searched and it is near impossible to not land directly on a 335 n54 thread using any/all of the above search criteria.

well a twin screw would put you back $7k AT LEAST... I think if VF or someone could put out something for 60hp or so for under $3k, it'd be perfect.

and no, I doubt trying to turbo this car with OEM parts of an N54 would work because the engines work very differently.
