You guys are talking about adding this or that to make more hp/tq in the 535. You all need to remember something. True it will be easy (many tuners have already done this) to make more hp/tq in the 535, but at what price? Adding more boost to an engine with a high (10.5:1) compression will shorten the engines life. Also how long can the stock tiny turbos sustain the increased boost? How abouit the tranny, will the automatic hold up to the increased tq of the motor? Guys I have been there. Once you start messing around with the a car and start making allot more hp/tq over stock, reliability goes down the drain. Every day will be a new problem and a new headache that needs fixed. Sure a 535 with more boost and some mods will smoke a 545/550, but for how long? When the modded 535 needs the expensive turbos replaced, the 545/550 will still be going strong. When the torque conver in the modded 535 fails the 545/550 will be still be running like a champ. In the end you when you total up everything (money for mods and money to fix stuff that broke), you probably could have bought an M5.
I was going to trade in my modded M3 for a 535. For the reasons I mentioned above I decided to keep the M3 and buy a used 545 instead. I guess I still want some headaches.

The stock torque on a 535d is is higher than the M5 so no great worries about torque strain on the transmission. As for the turbos, I don't know why you say they are "tiny" (unless on the 535i they are a different technology) but on the 535d the permanently spooled turbo is "smaller" than the other one - that's it.

I think with the 535i, a few simple bolt ons such as intake and full exhaust will benefit the car a lot, probably don't even have to touch the ECU!

...same situation applies to factory warranty,especially when messing around with ECU parts....
You believe it or you don't and take the "risk".

Quite a few EU members have had their 535ds remapped with no reported failures.

The 335 and 535 use two very small (tiny) turbos..
