B16 dizzy

ok so i got a dizzy cap and rotor for a del sol vtec.....it looks the same as the one the engine came with (B16a1) except it looks like its for a seperate coil? theres no "pin" on the inside and has a connection ont he outside. i was wondering if theres a different cap i could get for my engine or should i go with msd ignition? i dont get dizzys and coils and stuff so any info would help thanks.

ps how much does msd cost? which one best for my engine?

Msd isnt needed unless your engine is heavily modified. and the plug is just so you can convert your dizzy to MSD if you choose, u dont need it, just plug it.

ok so i dont need msd but did i get the right cap? ok so theres contact point in the center, and 4 contacts around that. then theres a seperate pin off to the side that looks like a contact piont bout 1 inches long on a spring. the new one doesnt have that .......
