Yes a 70mm is a little big for a stock intake/head car

BUT, he said he wants to do it right the first time (or something like that) and therefore if he is eventually gonna get an aftermarket set of heads and a cam and intake, then the 70mm will be perfect for him.

Then I also just re-read his post and asked which size would be good with his mods so far, in this case actually a stock one will do you fine. There's other things you need to focus your cash on first. Like exhaust/gears/subframes/pulleys blah blah blah. Then you can move on to a 65mm TB (or 70 if you have big plans for it)
