Basic summary off the top of my head...
Power out put is a variable depending on manifolds used but anywhere between about 430 and 550 bhp...
To make good use of the GT30 you will need to address the restrictive 4x4 exhaust and the restrictive elbow on the inlet.
You will also need to think about fuel supply (pump, wiring and piping), and if it is up to the job.
The injectors will fit straight into the manifold and fuel rail.
L8 4x4 Sapph or P8 large turbo Escort Cossie ECU will be needed without going to aftermarket management....
