how mutch nitrous can i shoot in this engine if i decide to build it. It will be: d16y8 or d16z6 Toyota supra 1G-GTE pistons Toyota supra 1G-GTE rings with LS (b16A) shoot peened rods Fuel system includes: SFC V-tec fuel controller 400CC injectors walbro 255 liter per hour fuel pump high flow filter bored fuel rail Aluminum Block guard ignition includes: MSD Sport compact ignition MSD Blast 2 external coil 9.5mm plug wires the coldest plugs i can find Timming will be retarded about 6 degrees i have a P&P head and a d16y8 head gasket. the pistons are lower compression pistons (9.1:1 CR) i know that this engine can handle 15-18 psi of boost, but i already have the nitrous system. i am going to end up blowing my dinky little d15 (currently has a 55 shot jet in it) soon and want to start bulding my budget d16. I am guessing about 125 but i want more opinions. How mutch nitrous would i be able to shoot?
