First of all I have a 90q with the V6 motor. I might be looking for a project car, a 20V 90 coupe quattro and I was wondering how the performance is compared to the V6 motor, exceleration, modification avalibility for the motor, and how it runs overall. I use to have a 10V 90, in my opinion it was slow and there were little mods for the cars motor. Is there a big difference between the 20V and 10V. Scott
