My recommendation on Stage ONE is to HAVE a too large turbo, as we are still dealing with 9.5:1 compression and a small cam. This is death to the pistons WHEN it pings like mad. Remember stock parts are great quality, but are NOT meant to be abused. Rods, rings, pistons are not high tech forgings. And it will ping, and if you control so much to not (fuel, timing) you suck out so much efficiency, it is hardly worth the effort.

The boost you will see so early (good to have on a PREPARED engine) is great, and midrange is breathtaking (my 301 was an easy match for a stout 455 in the midrange, very easy, enough that if I could keep up that power up to 5500 rpm (mine petered out at 4700 rpm, and redline was 5000 rpm), that is mid 12's with 4000#), but we have fragile stock CAST pistons. We have a cam that WILL build us lots of cyl pressure at low rpm, and add a turbo, this is a death sentence. Keep the larger turbo. You cannot attempt to properly match this combination. Match it up on Stage TWO.

Plan for boost to be coming up strong to hit >3500 rpm, if not more like 4000 rpm. Be conservative on what rpm boost is high at, all it takes is one death rattle to take pistons out and destroy the crank, rods and block. Trust me, need pictures of my piston?? And that was with a 800 CFM Q-Jet and DX secondary rods, and I still liquified a piston.
