A diverter valve and BOV are two very different things when it comes to an Audi. Please search on "BOV"- dont use one. injectors wont do anything other than make you run rich unless you have a bigger turbo and supporting software. Either chip it and maybe do an exhaust and intake, or get a big turbo and supporting mods (software, injectors, fuel pressure regulator, fmic, exhaust, spark plugs, etc.) All these things have been covered MANY times, it would be easier and faster for you to get your info by searching for it.

 

You do not want a BOV, you can get a DV for the same purpose, and as mentioned before they run between 30-150 US dollars. The DV is a lot better for your Audi.

 

you also dont want to get a K&N trust me its bad there is another thread on here called green air filter vs. K&N air filter read it and it will tell you why.... the search button is your bestfriend

 

But what about that old dude in K&N advertisements that drove 1 MILLION MILES on his K&N filter?!?! Lying scumbags!!! I guess my engine is fucked!!!

 

^^^ hahaha! only if the K&N is over oiled I've had it as many others with no problems. if there is a problem you clean it. Our MAF's are tempermental by nature.

 

i hope you are not wanting to put an intercooler on with the stock turbo cause that would just be a waste and probably lose power

if you want to make good power go with FMIC, a Garret 2871R turbo is like a good common size "BT" Big turbo

fuel system

chip or what ever map you want to support that turbo

K&N filter or someother induction system...

Intake Full exhaust down pipe mid pipe ect...

and internals if you want like

je pistons

ferrea springs and valves

Carrillo rods

and what ever else you would want to make a good quality motor

and not be cheap about it.

cause being cheap gets you no where but with a broken motor.
