The only kit available is from Island Turbo but it isn't the twin. Or you could buy #502 on E-Bay. The only parts I know of that are in existance to recreate a twin set-up are in Rob's shop for the car he has and I don't think you could get him to sell then even if you were his brother! If you were on better terms with him and could examine the parts I believe the parts could be copied and or recreated. Someone else is also interesed in doing this but I don't know how far along the project is. David Teitelbaum vin 10757 [duplicate quote snipped by moderator]
