good day to all
recently in January i purchased a 2007 A4 2.0T quattro auto,
and i got APR just few weeks ago, running 93 oct. (put v-power 93 only)
i have a few following question, and hope u all can help me to solve it. thanks

1. my destroyed the first diverter volve, currently running on the most updated unit. i think its either ends with G or D. now, if i upgrade to Forge, would it hold the power even better?

2. at this point, without swaping a turbo (auto should not be able to handle it), what else is there i can do to get a little bit more hp/tq? and what is the maximum power this transmission can hold?

3. my experience with my previous car about lowering a ride (e39 540i), most people change their springs and shocks at the same time. however, at this point, i have only found several different brands of coilover for quattro a4. or just springs. do they not offer shocks? i am not familiar with quattro system. is it a design thing? if i only do the springs. is that good for the car? current millage is 33000 miles.

4. i have researched a few 18" wheels on the market. but i am trying to figure out what size the tire suppose to be. for you all who is running on aftermarket 18s, whats ur profile on the tires

5. final, this is really not a question. but i am thinking about putting bbk on this. not major brand. likely direct factory sale product. but cheap look forward to it

thanks for all your help

 

1. Yeah, the Forge DV should hold better.

2. There are people putting bigger turbos on with auto tranny, getting around 350 HP. You could also get test pipe or high-flow cat and exhaust, and aftermarket intercooler.

3. Koni FSD are popular shocks. I'm currently running the OEM sport shocks with Eibach Pro-Kit springs. I imagine the ride would be a little better with shocks tuned for the springs, but it's OK.

4. The S-Line models come with 18" wheels, 235/40R18.

5. I don't know much about BBKs, but I haven't see any I would call "cheap".

Happy modding!
