No there isn't they believe that 5.4 is enough[ in Auss]. The home of these engines [U.S] use suppercharges to gain heaps of power and torque [pulling power] its a possitive displacement type that fits where the inlet is. This type is used in the latter Lightnings which is a F150[?] truck type.They can do low 14's on the 1/4 mile..
Believe me fitting a twin turbo in a BA would be hard work though I can see where a T 66 single would work and fit o/k. Have to be carefull with that much power on transmissions etc..
Fitting turbo would be around $10K done right ..
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
