Ok 2 questions but they are both big. When answering please be specific( Ex. No abbreviations). First one, im going to go shopping for a s4 but i want to get the 2001.5 because that seems to be a good choice from what ive read. What big differences can u tell to set it apart, ones someone like me could see. Number 2 I want to get some K04 turbos and Chip it but im afraid that i have to do more, Do i have to buy a whole bunch more things and what. Also will i be able to run pump gas if i do the upgrades and what octane is recommened/ how low can i go gas is expensive. Thank you for helping a new guy out

 

For the average driver the 0-60 with a stick on our cars is about 5.8, best case scenario some places have it listed as 5.4 and others 5.6.

 

hey noob, plz learn to search. I mean i have seen this at least 3 times this week.
