if you wont to remove the cas (u have sed u dont wont to i know) you could go haltech it does everything you wont and instead of the cas you can use there halleffect on your front pulley wich is more compact. if i had a good photo of myne id show ya.
the haltech can run the standard cas but i started having probs over 250hp for some reason and i changed the reluctors and everything but in n/a form it will be fine.
