im am just about done working on the suspension on my '85 4000s quattro. I have replace all 4 a-arms w/poly bushing and put new poly bushing on both front and rear subframes. i have all put in all new hardware. and new eibach springs with koni shocks. it def. stiffened up the ride a bit. well now im working covert it 2 fuel injection w/ the mega squirt system, and now im wondering what i can do for performance. so if you guys could help me out that would be awesome!

 

well the fuel and intake should give you a noticable increase ... exaust , cam and there always is an option for turbo or a turbo motor swap all you need is a 10v turbo or for more power 20v turbo
