guys, I wanna get rid of my dizzy, and use coil packs. Can I buy an LT10 with an X4 ignitor box and do away with the dizzy cap/rotor? Or do I need to buy the LT12 and run 6 coils?

you can do away with the dissy cap and rotor as long as the ecu has at least 3 ignition outputs and this will allow you to run a waste spark setup or 6 outputs for sequential spark, you will still need the dissy to trigger the ecu

yes mate an lt10 with X4 box will do away with your dizzy, however the actual unit still remains to house your cas. however an lt10 will only allow semi-sequential firing, while an lt12, as stated above, has 6 ignition outputs allowing one coil per cylinder, thus fully sequential firing. even better, go the ltx12, which has the inbuilt ignition module removing the need for an X4/X6 box
