I would be interested on the following conditions:
1) Priced affordably - While there are a good number of members who have purchased new 987s, you are looking at a kit for the 986 models if I understand correctly. Although this is a generalization, the folks who own the 986 do so because they don't have the limitless resources to purchase a new 987 which has a significant hp increase. Therefore, I would be interested only if the kit was relatively cheap.
2) Easy to install - I wouldn't dare attempt to change the oil on my 986, let alone install a turbo kit...but others would. However, even for those of us who wouldn't install it ourselves, it would be cheaper and easier to find a mechanic who could install a more simple kit.
As far as destroying engines....I am not concerned....I never buy the first thing that comes out and will wait to see what happens to everyone elses cars first
Just my thoughts,
Doug
