dynamic turbo problems?

[rumpig]

went and saw a guy today about fitting a turbo to my 1HZ, and he suggested a "dynamic" brand turbo. haven't really heard anything about this brand (only heard of the name itself), so wondering if anyone has had any bad experiences with them.
has anyone fitted one of these to there 1HZ cruisers before, the price i was given sounds good so i'll be looking at installing this very soon unless someone advises differently from previous bad experiences.

thanks
