#5299, "Questions about the Hahn Portfueler system"
Hi, I have contacted Hahn and I have a totally rebuilt engine and they recommended me to get an MSD ignition box to controll spark timing. I have MSD wires, MSd coil pack and NGK performance spark plugs. My question is this with a T3/T4 turbo running 20 psi will I need an aftermarket ignition box? If I dont have one will my engine grenade or be a catastrophe not to have one?
