If you are still looking for a turbo set up I have one. The twin turbo set up I have is from PFM. I have all major componets,you can   run it with a blow through or I also have a pfm intercooler w/new cores,this set up mounts the carb behind the engine and also cools the fuel at the carb.I had this set up on a 454 chevy w/logs for exhaust. Any questions call 801-721-0280 or e-mail www.rhazzard01@aol.com Thanks
