I'm going with the TD04 its a quicker spinning turbo. With both running the same HP the TD04 will spin up and be on top of the TD05 before the TD05 can fully spool up. If it was a TD04 against a high HP TD05 it would be a different story... Every shift means the TD04 will spool up faster and gain more and more. This is why some people prefer N/A because they don't have the disadvantage of the turbo lag or having to wait for it to spool up. personally a 500hp little turbo vs 500hp big turbo vs 500hp N/A. I think the NA would win follow by the little turbo... This is all my idea though and theory...
