Not correct. Both have the same IC #17517791909. The inlet pipe was modified from 45º to 0º angle and it was welded wider IC supports to reuse the car IC supports. It is not a simple bolt on but it isn't also a impossible job.
About 30hp and 55hp after ECU tweaking. I have all the specs of my car in my sig. The IC is from the germany company WAGNER-TUNING

 

404 hp and 830 NM.. WAAAUW !!!! my car has 290 HP and 630 NM and i think its fast. wonder how MUCH faster yours is hehe..
do you have automatic transmission or manual ?

 

I have a 535i 2009, was gonna install it myself, ill let you know how difficult it is. I did check with a place just to see if they would do it, and downpipes for me if i found it too much trouble. they are called Bertinis European on 45 south up here in the woodlands..they were concerned about it voiding my warranty but they said they would DO anything.

 

All 35d engines only have automatic gearbox. There are a guy from sweden with a 335d putting down 445hp. These engines have a insane potencial.

 

okay.. thats sounds wild hehe. what about the transmission ? can it hold to that much NM ? do you know if i have the same transmission as yours ?
