after researching some it seems the b18 is a lot more expensive and will be harder todo. The b16 seems to have better aftermarket support too. I might eventually get turbo but for now I like the respect of "all-motor". I plan on taking the interior out (how much will this save?) And getting a CF hood for weight.
I was also wondering about the wiring....will I need a special harness for it?
