If your going turbo on your car I'd like to know how much you want for parts of your nitrous set-up, especially the direct port...

the direct port i sold
i'm selling my short block $2800 or long block with heads $5500. the short block comes with everthing, the only thing i'm taking off is the heads and intake set up and oil pan and covers.

Looks like some pretty extreme lobe ramp rates on the first cam. I wouldn't think either one would be neccessary to make great turbo power. Either way, an S88 will flow enough for any reasonable 346ci goals.

my old ITS GT80RBB worked awesome on my 346, my vote is that or any 76

Best for what?

Best for pump gas? 76mm range.
Best for race gas? 101mm range.
Best for head gaskets? 106mm range.
Best for early torque delivery? 67mm range.
Best for traction? 95mm range.
Best for everything? A compromise between the above that only you can decide how to bias.

In reality, decide how much power you're looking for and then choose a turbo in that range. Don't do it in reverse.

I'll be happy with 900hp to the wheels. i'm thinking of going with a gt47-88.

A S88 would be way better then the 47-88 IMO. Even a S78 or 80 would make 900 to the wheels and spool quicker.

For "only" 900 to the wheels with a stick tranny, a T74GTS would spool quick and achieve that goal. Otherwise, I would go with the ST76. The ST76 will make 1200 fwhp and spool much quicker than any 88mm.
