to answer my other Q man this went deep but okits a lesson for me what should i use i plan on getting a new mannifold and a throttle bdy with a cold air and headers and x pipe what sized should be used

Hamutoff

just be sure to match them up
is the engine otherwise stock?
I *believe* that the 93 cobra intake's opening is sized for 65mm otherwise(also you dont have to buy an egr plate its intergated save a few $$, its good for about 400 crank hp) go for 70mm on 99% of mild/moderate intake packages out there as they are most sized for 70mm

Most manifolds are sized either to a certain throttle body opening, so makes it a little easier to decide on, if you picking the correct rpm range manifold then whatever the throttle bore on that manifold should be the correct for the rest of your matchup.
