not another boosted 5.3... Hey guys, first post on here and that's cuz I'm jumping on the 5.3 twin turbo bandwagon. now I've been doing a ton of research online and going through countless threads... but it is my first fuel injection build and first turbo build. just picked up my 5.3, wiring harness, and computer at the yard for the low price of a beater 92 Honda civic 
. I've been pricing it out and trying to get the right turbo/cam/head combo down but I really need some help as it seems that no one has this exact set up and I only wanna do it once right.
For the turbos I was looking at twin 72mm .68a/r

for the cam I was looking at this 224/232 0.59/0.59 115 lobe separation

as far as heads go, I've been reading that the 317s drop the compression too much and its better to get 243s or something similar. others are saying that the stock 5.3 heads work well with boost as well, so I haven't really decided on that one yet, it'd be cool to just use the 5.3 heads to save money but sounds too good to be true.
I will also be running an ls6 intake with 96mm throttle body, if there's something better without being ridiculously more expensive let me know
The goals for this engine are 700whp on 93 pump gas and 900whp with meth injection. hopefully around the 15 and 18 psi range but at this point that's all speculation... although if 1000rwhp is even possible on meth that would be a cool milestone to break
let me know what you guys think, if its even possible, or if I've got it all wrong.
Thanks for your time, Ray
