So it is hard for me to justify to buy a turbo kit that will only add me another ~20whp for 8-10k (which is my assumption of ur price).
Also isnt the setup for the 135i and 335i different in the way the engine bay is setup in relation to fitment?? Any reason u guys didnt do more homework for a new fuel pump which is entirely needed to make big power??
also I am assuming u found the stock fuel system max's out at 465-470whp so that is the roof for this turbo kit with race or pump??
Stock fuel pump is good for 3000psi, *when* they werk
