2013 35D - Stage 2 Checklist...

[Ricky Bobby]

Guys - my wife loves her E70 (2013 35D, Alpine on Cinnamon/ Sport Activity etc) and plans to keep it a long time - it will be paid off in a few months, and thankfully our great state in the free South doesn't have diesel emissions, so I'm planning on doing the Stage 2 conversion for her -


**FULL DISCLAIMER**


I am getting too old to spend days wrenching on these cars, cleaning the air filter, some basic preventative maintenance, monthly detailing of the interior/exterior, oil changes, and maybe some other items are the extent of my DIY on the E70. I do NOT have the time to go back and forth with tuners that are not local, nor having issues and having to do troubleshooting with them.


Thankfully, 20 mins from my house, is Bimmer Performance Center (BPC) in Raleigh, nice guys, have done some non-planned work on my E53 in the past and I brought the most recent fuel filter service for the E70 as well, it was fair and done right.


Since their downpipe/delete pipe does not include a Diesel catalyst which is a MUST for my wifes car due to the smell, they told me they are more than willing to do the install and conversion if I bring my own deletes, they can provide the rest of what I would need.



This brings me to Rawtek, or ATM, or BuzzKen/AARodriguez, which have options for a DOC - I'm leaning to Rawtek or ATM because they are the most affordable options.


So please feel free to check in with me on the items I should be looking to do around or at time of conversion (I.E. preventative maintenance items), the vehicle should have 75-80k miles - I do plan on doing a transmission service with filter/ZF fluid change around the similar time.


1) Tune - BPC Stage 2 (not the + as it smokes a bit more)
2) DPF/SCR/EGR Delete - flushed tanks with distilled water (Rawtek, ATM because of the DOC option)

3) Swirl Flaps Delete (BPC can provide)
4) EGR Race Pipe or Blockoff? (I am not running meth but is there any advantage on doing this? Or will blocking off work as intended)



Items I am considering adding to the conversion time:


5) Carbon cleaning? BPC told me while everything is open its a good idea to do, and then will not need it afterwards once the deletes are done
5) Thermostat/Coolant Change?
6) Intercooler Upgrade / Boost Hoses (ATM has just come out with their intercooler kit which I believe in on a stock tuned vehicle, at $800 including the ASV hose, it will delete all the quick connects which can fail and improves 90%+ of core size compared to stock)




Anything else you guys can think of let me know - I'd like to cover most of my bases and hopefully have a minimal amount of maintenance going forward after the conversion, so if there is anything "while I'm in there" I would want to add it -



Thanks!
