Slant six turbo cost analysis: 300 hp

if you are starting out then going with the 4bbl intake is the way to go. like you said most of the time they are only $25-$50 more then the 2bbl. depending on your car there may not be hood clearance to run an adapter plate and a carb hat. i know i ran into the problem of the carb hat hitting the hood without an adapter. on another note you could always run a 4bbl and just disconnect the secondaries. i did that while tuning and the power difference between the 2 and 4bbl wasnt much. all things to consider. there is no one way to do all of this. there are so many combinations and possibilities its staggering.
