I'm sure this has been covered alot of times. but when i search it doesn't have what i'm looking for. there are alot of help threads and conversion threads but nothing to tell me the difference between the 2. what i want to know is what is the difference between the two? Which is better and why? pros and cons? modifiying is it easy? (not talking converting) I found a car on CL and its a 88 GT I want get it to put into Rallycross and have a car to use on the street once in a while. I don't want to get it if there is alot of issues with non mass air metered cars or if moding them takes more money or they are limited with out converting them. someone please help.
