Default me confuzzed

hey guys im new to the site and to GM,
i just have a few questions.
i have been reading alot on here and i read a really good post on camshaft selection in here, also on choosing the right intake.

I have 93 240SX that im swapping a lsx into, i already have all the mounting kit for the vehicle but im hung up on what motor to get.

its all comming down to money for me, I have been looking at lq9 and lq4.
the LQ9 seems to be hard to find, and its a little more money.
so is it worth getting? i read that the rods are stronger on the 9 and the pistons are flat top instead of dish like on the LQ4.
but horsepower wise what are the limits of these motors?

I also read that the LQ9 basically has an LS2 bottom end

really what im looking for is what route i should go?
should i get an lq4 block and stuff Lq9 rods and pistons in it?
or should i buy a complete LQ4 and just mill the heads to gain some compression.

i would like to eventually be around the 450 to 500hp mark

thanks for anything you can guide me on.

also what are the flow capabilities on the stock heads ?
l92 heads worth it ?
patriot alum ?


thanks
