The black top 20v is a great engine that stock will have less power than an fa20 and without FI will always have less torque. If you were to mod it to rev and make NA power you would want a much lower final drive to compensate. And after all of that you probably would make less wheel horse power than a full bolt on FA20 on E85. It would be a lot of money and effort to go backwards in power and drivability. It would make a nice sound tho.
