What am I Forgetting for my Build?

[AlphaWolf1993]

I recently ordered a GSR block. I plan to build this mofo to about 550-650hp depending on if I want more power. My current build list includes:
Laskey Racing sleeves (Benson), Head will get a "Stage 2" street/strip PnP, 9:1 Pistons (best brand for high power?), Connecting Rods (Again, best brand?), Full valvetrain by Supertech, Stage 2 turbo cams (once again, best brand?), Edelbrock Victor X Intake, Cam gears, massive injectors (are 1000s too big?), probably a fuel rail and fpr, Intercooler, turbo mani, and ACT stage 3 clutch . I plan to haul it down to Florida and get it tuned by Phearable. I may have missed a few things.
A few questions:
What turbo would produce a good, full powerband but doesn't take forever to spool? I've seen similar builds use a 6262.
Are there brands that are better than some listed that would be necessary for this power?
I thought about water injection...

I already know that there will be a lot of "google is your friend", and I've done a lot of research. I just want a little more person opinions. Any and all comments are appreciated...as long as they contribute...
I will also respond to questions and comments ASAP.

You should take a look at guy_from_nerk's build thread, lots of detail in it, you can get some ideas for parts and brands to use.

CP pistons or JE pistons, Carillo H beam or Eagle H beam rods, dont go super tech valvetrain go skunk2 pro series dual layer springs and titainium retainers, skunk2 pro 2 cams or cower cams, 1000cc but you arnt making 800+hp so you can go lower cc, your crank shaft im running eagle, cv joints, transmission, LSD to help put down the power

Will Eagle rods be strong enough? I read in a (older) post that Eagle beams were not good for much more than budget builds...and is there anything that can replace the skunk2 springs and retainers? Or at least comparable?

I disagree on skunk2 valvetrain. Supertech is plenty good. If you need parts pm me, we carry about everything you're looking for. Scar makes good stuff, eagle can be hit or miss.

Also- run 1000cc injectors. There's a link with a table of power vs injector size. You don't want to run them at a full duty cycle.

This, that's 20whp per item, per tire....troof!

This guy has everything you need, check him out man, he'll take care of you. And he's cheaper than the hookers I use

Loving the feedback guys, reassurance and useful information. I'll definitely buy some PMS products...after I drop this bad boy in and get it tuned >

 

[AlphaWolf1993]

Alright, here's another little detail that's been bugging me...the Supertech valvetrain. Will it be able to handle higher RPM's as well as the higher hp?
Also, transmission. Should I really spring for the GSR w/ LSD tranny, or get the LS rebuilt with LSD? This will be a street/strip car, if that affects your answer...

 

[hgocasca]

I'd do the ls trans, I run that with my n/a b17 and still pull good times. And the supertech is good stuff

Alpha, talk to Laskey. They can build you your bottom end with all the pistons, rods and bearings- blue print and assembly. Very reasonable price too. Probably the same or less of what you would spend buying the parts on your own and putting them in. If they're already doing the sleeving you should just let them handle the whole motor.

Go with a GSR transmission and an LS final drive. It's the best of both worlds. Low gearing and that higher top end. Limited slip is essential though whichever route you do go.
