Hairy green toads from Mars made Stulen James say: > This weekend I am going to look at a 88 90Q 10V and a 90 90Q 20V. I am > wondering if there is any signicant factors that might wight against the 20V > engines. As I see it: > Pros: > Has 35 more hp Yup, and it makes quite a difference. I have a 10V 100Q and a 20V 90Q, so I get to compare them side-by-side a lot. The 20V also has a tighter suspension, and better interior (seats, etc.). > Cons: > Worse fuel economy(????) Nope, we both get about the same milage. The 20V however, really needs at least 89 octane. My 10V is usually somewhat happy with 87, unless the A/C is on a lot, or I really want to punch it. > Extra complexity of cams and such. This is an issue. The 20V90Q is one of the hardest engines to work on. There is so little room, every job is a JOB. My 100Q is a breeze to get into. I suspect that's because it's a 100, not a 10V. I think the 10V90Q will be almost as bad as the 20V90Q; the hood is small. > As I understand it both these engines are 'interference', so if the cam belt > breaks on either, it is going to cost a lot, more I would guess on the 20V. > > What is the cam belt life?

The cam belt is a big job because of the tight engine compartment. Expect to pay at least $300 canadian for the job. The 20V engine is interfering, so break = $$$$. The 10V engine is not interfering, so break = tow to garage to replace. Don't compare the GTi to the Audi. The belt replacement is different. My old Golf was a dream. Replacing the belt was a 10 minute job with a wrench and a screwdriver. I won't touch the Audi. -- Andrew L.
