I have a 2001 A4 1.8T sport 5spd 90,000 miles. Just Did Cat back exhuast SSauto chrome Wich im happy with. Full timming belt job and all new fluids.
I've seen on ebay some Turbos that say up to 250 to 300 HP ECT...
Now my question is from my stock Turbo im at 180h can i use the new turbo at 250hp and not have to do a whole lot to the rest of the car ?? or shold i go with program then DV valve..
And wich Dv valve do i go with

 

You will need a new tune, larger injectors, larger SMIC or FMIC and most likely a stronger clutch.

Your car stock tune is 170hp, chipping it will take the stock turbo to 200-210 depending on what supporting mods you have.

 

Sorry new to the whole audi thing what is SMIF-FMIC??
so after doing the exhuast what should be the next thing to up grade Not trying to get 350hp around 300hp would be nice If a chip which one If a DV valve wich one
Anthother Questioon i have the S4 suspinsion i want to lower the car but not to much if i do the 1inch and 1/4 is that off the stock hight or do i get the chose of the s4 hight i know my car is lower then a reg audi i can see it i have the red shocks?? if any one can help would be great

 

Hey there I just installed a new cone air filter for my car in replacement of the stock airbox. I wanted the performance definitely but mostly the sound of my dv
Issue is there is a tzzzzz come from the motor kind of towards the back that's either covering up the dv sound or not letting it release the pressure

So here is a YouTube video of the sound. Anyway Merlin's out there can tell me what it is?
