Jeff, If money isn't an issue, contact these guys. They can build you what you want for what you can afford as long as you can afford thier low end motor. Which i think starts around $3000. He quoted my friend $6000 for a motor capable of 700hp.
Just a thought. Also, high compression pistons arent nessicary with turbo motors. 9:1 is more than what you need for what you want.
A guy that I used to work with wasn't to savey on the high compression + forced induction, and bought a 10:1 motor, then threw a roots style blower on it and a 8 pound pulley. Well, I can walk into his garage today, and see the hole in the ceeling where the intake flew off the car and into his attic. /ubbthreads/images/graemlins/grin.gif Thats a hell of a way to waste 10k.. Granted, where talking tottaly different setups, but it still the same principal. The 8 or 8.5:1 with the correct turbo, will give you reliability. Also, aluminum rods will not last as long as the stock cast ones. Hell I have a talon with 280k on it, and it is all stock motor with 2g manifold, 3" turbo back, small 16G hard pipe and the stock smic. I always kept the maintnace on it and changed the t-belt 2 times. It might not have a ton of power, but it never left me stranded until the head gasket decided it needed to take a break.
