]hi every one.
its been a huge change for me from a Natural aspirated to turbos car. i just bought a 2000 audi s4 6 speed with the turbos. the car is currently showing 19 psi. other than that i have no way to tell if it has been chipped or not. its was sputtering very bad and i change all spark plugs and gap them to .32. the sputtering is gone but its still hasitates two to three time before it can hit full throttle.
now i am planning on taking out the engine and tranny and planning on upgrading to k04 if they are not already upgraded in which case the parts that would be needed to get the desire 400 to 430 whp. to my knowledge these i have known so far from searching through the forums but i am still confuse.
i have so far K04 turbos, clutch, engine and tranny mounts, inter coolers, wide band, down pipes with 200 catted cells, boost guage is already there. diverter vales and bi pipes.
completely confused about what would be needed for fueling as injectors size. map sensors fuel pump. map hosing. etc. how the bar system works
please i need advise from people who have done these upgrades and are quite well educated on these matters and have done these work them selves. i am in no way disrespecting any other members at this forum just need help in doing the upgrade.
please any help would be highly appreciated!!.
thank you
