Reason for leaving standard cam is through some searching people have been saying the standard cams are decent enough for a turbo setup, but im sure a dedicated grind would be superior Depending what you buy the LS1 out of, VX onwards i think had the LS6 manifold standard. Depends how crazy you wanna go and how much cash you got. People have bolted turbos onto stock LS1 and changed valve springs only and made decent power reliably

GT4202 on reversed VE manifolds (weld up at home job) It will work fine. LS6 manifold, mafless tune, possibly bigger throttle body Will probably all ready have it. Won't need a T/B, no point going bigger than the smallest opening anyway. upgraded timing chain, upgraded pushrods/lifters maybe? Don't bother. If you have money to spend go for it. ARP stud kit, head/pistons/mains etc Wouldn't bother unless you want to jam more than 10psi into it. Standard coil setup Will do 1500hp Not sure on oil pump Factory one T56, twin plate clutch Single plate will be fine if the car is light. Have plenty of friends running Z grips in 400+ rwkw cars Chucked into my VL calais, thoughts? Reason for leaving standard cam is through some searching people have been saying the standard cams are decent enough for a turbo setup, but im sure a dedicated grind would be superior Standard cam is fine, its little and on a wide LSA. THe turbo does the work really. 3Chars

Bang for buck, twin turbos on a standardish engine would be a good move imo

My previous VT LS1 made 270rwkw from Brett @ LSx Garage. 1 3/4 stainless xforce extractors highflow cats 2.5in mild steel redback Mild cam - which was put in for an FI application Valve springs Pushrods Double row chain Pod filter setup standard auto and 140xxx KMs on clock Drove it for about 10-15xxx KM and the auto was only starting to get a bit sloppy... Never took it to the track so don't have a MPH figure
