just a thort, is there any way you can run a PD head and injection system without an ecu or any complex wiring?what about the 2.0 PD, are they reinforced?surly you can do a load of head work on ALH head, then crank up the fuel, maybe 12/13mm pp in an M pump, ball bearing turbo, charge cooled, meth/water injection. i recon 300bhp cant be impossible.what makes the PD so gud? the valves are the same size, is it just the extra fuel pressure?
