buy an RS4, reliable, and built to handle the factory 420hp!!!!

 

im thinkin an s4 would be hard to get where you are.. but if you can it would be much better choice... those things are ****** fast with good mods

 

I will soon have 450hp in my B6 A4 1.8T. I have already dyno'd at 400chp. 400ctq with a GTRS turbo. When I get done boring out to 2.0, port match the exhaust mani and intake mani, and drop all new valve train parts and forged internals........I'll be damn close to 450chp. All depends on fuel at that point. 450 will prolly be the max I can get out of the stock fuel system. All of this on Revo BT programming. It's not wheel horse power, but damn good for a B6. To get that # to WHP with the my setup, I'd need to ditch the GTRS, put on a GT3071R or bigger turbo, run 034 standalone programming, run bigger fuel injectors, bigger MAF, etc...
