I Have just hit 150k in 01 formula a4 the cars my dd I drive the card like any 20 year old would all though I'm pretty good about maintaince fluids changes,breakes the regular...mods are long tubes,ory with turndown,lid,k&n,granatellie maf, smooth bellow,free mods, 100lbs weight reduction,tubular control arms and pan hard bar,lcr brakets set to lowest hole,used tranny swap has roughly 85k on it...I think that covers it

so should I start building a motor or start replacing stuff on current motor in te car,keep in mind it is dd but I want the car to run 7.5-7.8 in the 1/8th on motor

 

If you DD the car, I would start building another engine.

 

Ok then then what the best budget build I could do on mine own
