What 'track' work are you looking at? Do you need response or high end power?

TD06, GTX3076 etc are decent sized turbos. They will be 'laggy' and take quite a few rpm to get on song.

IHI VF series are smaller so they get on the power quicker. Twin scroll will get you on quicker again. But the VF's will not make big high end power.

You seem to not want lag but have big top end power. It is one or the other unfortunately.
