Help With a turbo build!
I have decided to use the STS kit, and the OBX FM on ebay, are there any upgrades to this kit i should cosider?
What about my short block, I wouldn't even think about trying to build an NA LS1 to 650WHP, can it be done reliably through FI though? If not should I build the bottom end or go with an aftermarket short block (probably a 370) from a vendor?
What other parts will be needed to get this goal, I will be getting a FAST 90/90, either SVO 42's, or 60's, Patrick G turbo cam, What will i need for the rest of the fuel system? and what else am i missing?

60's, rails, and a Walbro will make it to 650whp. Anymore and you will need another walbro.
-Im guessing the 90/90 would me more power than the LS6/PP LS1 TB right? (I may be wrong just wondering) but are you guys saying it wont be enough to warrant the money spent?
-Same question as above only this time relating to the LS6 cam VS. A custom spec'd turbo cam.
-would I be better off forging my current bottom end or going with an aftermarket forged bottom end (for the price some of these sponsors offer shortblocks at it seems like it would be best to purchase a 0 miles forged shortblock)
Also I plan to have all the tunning done by jeremy formato.
How would this turbo match up to 370 and what a/r would i need it to be to spool quickly and still make good power on the STS kit?
