Apparently there's a lot of interest in the modification of the CR-Z in the Japanese tuner scene. Top Secret and HKS, two of the largest and most respected tuners are doing development. The Top secret car has a Trust TD04H turbo mounted @ 0.4 bar. Supposedly they're getting 150HP out of it. Speedhunters has an very short article (and beautiful pictures) about all this: GALLERY>> THE CRZ @ TSUKUBA - Speedhunters EDIT: I forgot to note that I'm just waiting the the old-people-being-old and holier-than-thou comments.
