hey. i have a 1991 audi 80. the engine is a 2.2l 10v inline5. the car has around 140,000 miles. i was wondering whether or not it would be worth it to buy a rebuilt 20v turbo engine or to just rebuild my engine and add a turbo? also i was wondering about wat really makes the 20v better than the 10v? thanks.

 

morte power and a non cis fuel sys (cis can be a pita)

 

20V has more power and even bigger potential, parts are somewhat rare and expensive. Stuffing 20V into an 80 is going to be a PITA but it has been done. The stock CIS is more reliable IMO but difficult to get more HP due to the very restrictive mass airflow sensor.

 

a piggy back fuel sys can be added to the CIS one .... I still agree though ^^
