Tuning a audi a4 2.5 tdi v6 quattro 150hp
Joined this forum to see if anybody has done much in way of tuning this type of car as i have started with removing the 2 cats underneath and replaced with single 2.5" s/s pipe,also removed silencer. Have kept the frontpipe and backbox standard until the upgrade turbo is fitted,also fit race 683 nozzles and remap.
I am not sure of the turbo yet,i was thinking of a direct replacement with hybrid turbo but they are pricey and was wondering if any other alternative to this with little mods needed. My car is 1999(V) AFB engine 150bhp
Any advice on this engine for mods?
