I know what you mean when you say know your own car, i've worked on my other cars in the past but never had a turbo'd one (if it makes any difference) so i dont want to risk anything but help from other members would be greatly appreciated as i imangine alot of members have great knowledge of these cars
there are some jobs that a pro does need to do like turbo rebuilds ect but most of it mate is just like a n/a car tbh just make sure you fully understand the job your doing before you tackle it.yh theres loads of people on here who know the ins and outs of these cars.some off them have had there GT/GLANZA'S 10 years or more but yh youcould do alot worse than put a post up of the job your gunna tackle and see if any1 will help you!! the age old saying if you dont ask you dont get!!
