I haven't used that box, but i know many others who have, it works fine, it's a little much for a stock engine, but it won't hurt and you'll have all the ignition you'll ever need.

you don't need a different dizzy, but a upgraded coil helps.

i have the accel300+ CDI and it works great, but the controller in the glove box ticks pretty loudly, but on the road you can't hear it.
