Question Any VF36/37 twin scroll convertion?

Or actually better a PE1825 twin scroll convertion. Interested to know who has done it and results.
What motor (EJ20,22,23,25,26) are you using it and preferably dyno numbers. If not how strong does it pull out of the corners. What is the RPM power band (3500-7000RPM, etc)

Thanks,

Nativo
