How to Build CFI.

[MHR Racing]

I have a dune buggy project in mind. I have alot of knowlegde in building
engines and race engines and i'm building a vw 1835 as i dont want to
overstress the motor or over heat it since its going to be in the mud. BUT i
am building i really really really nicely built "to the hilt" motor and i
wanted to do it as low buck as i can. now this is where you guys come in. I
wanted to know how do i build a 1 sensor CFI system. Ok i know it exist
because its going to cost me 1 damned thousand dollars. I know this. Its
adjustable from the inside of the car and only works w/ 1 sensor. Also i know
it's Throttle bodies look like the dual carbs you would normally buy....what
do you all think?
