Yeah I don't think 10-15K will be enough. Turbo setup only will be at least a 3rd of that before install. Exhange rates freight and installs will send it well north. I am currently FBO with ethanol

you going twins or single? whos kit are you going to use?

Tuned to 600hp you will have issues even if everything is forged. Drive train, additional fuel supply, all the other additional parts. These cars throw many problems at you when stock. If you want trouble free motoring, a 600hp n54 wouldn't be it.

Anybody had their injectors replaced on a 335i N54? Think I am up and its going to hurt

You problem with autosure lies with your car needing to be stock to claim but if the rattle is only heard with the aftermarket downpipes then how do you proceed.

You could try using the MHD rattle adjustment and see if that helps. I went through the exact same process and managed to get the turbos replaced under warranty, but even the new ones have some rattle

MHD is highly recommended. Huge abundance of info online that will answer everything. I am pretty sure there are more tuned 335i's on the road than stock it seems

335I E92 PE modded Exhaust. Less packing and less Perforation in the Mufflers. Cold starts sound like an exotic super car. $120 I had this on an E91 wagon. But it was just to loud for me, I have to many grays and early starts parked next to the toddlers bedroom didn't work for the wife

Yep already use the cold start noise reduction purely to avoid waking up my toddler early in the morning.

I installed my own intercooler, charge pipe bov, plugs coils etc , but harder stuff I have payed workshops to install. Even the easy stuff I get them to do now as I just dont have the time. All the aftermarket stuff can't be sourced here ( LSD , downpipes, upgraded LPFP) so I I pay them to install when I bring down and I have used places I know do great work. I am pretty sure I havent insulted any of them but I will double check

Are you joking? If I pay someone to paint my house but supply the paint am I insulting the painter. I am paying him for his time and labour. Thats why I said take it to one of these non precious BMW Techs

I have a 335i N54,i have had it about 5 years. Especially when cold I would say yeah it a noisey engine and similar to diesel. But it goes hard so I suck it up and ignore

Its a pretty easy job, I did my own. You could probably take it to a non bmw specialist and just show the a youtube clip of the install

Hard case reading watching these two Vendors going at it. Re the new Vargas options on the n54 and chinese castings http://www.n54tech.com/forums/showthread.php?t=48176
