Hello everyone, I just completed building my 1978 Datsun 280z Motor with pretty much all new or rebuilt parts besides the block. I'll run down everything I have and have done. -Stock L28 N42 Block with dished pistons (not rebuilt or anything) -Rebuilt Late E88 Head, Ported, 1.2mm head gasket -Brand new Triple Weber 40 DCOE from TopEndPerformance with the Canon manifold -Brand new 3-2-1 headers from TopEndPerformance which I also wrapped with header wrap -280zx Dizzy "upgrade" with E12-80 box -Carter fuel pump -Also fully rebuilt 5 speed Transmission (Long gear ratios) -Planning on getting the MSD Ignition Soon I got the car running (extremely loud as its open headers atm) didn't have to adjust the Weber's really besides to get the idle down, drove the car and definitely have to ease into the gas, straight full throttle the car stumps for a second, could just be the car wasn't fully warmed up. My questions is if the Jets TopEndPerformance provided with the Weber's are perfect for my setup and what some of you guys think should be changed? I am very new to the Weber game and plan on learning how to tune these things properly in the future but for now I definitely would like some guidance before I get tuned. I will list below the Jets provided with these Webers Main Venturi - 30 Aux Venturi - 4.5 Main Jet - 115 Emulsion Tube - F11 Air Corr Jet - 200 Idle Jet - 45F9 Pump Jet - 40 Pump Exh - 50 Needle Valve - 1.75 I will keep this post updated as I get my webers tuned and change out the jets
