I know the ls6 intake flows better overall, but is the larger throttle body on the ls2 intake better for boost? Running a turbo lq4.

 

If the ls6 intake flows better even with a smaller throttle opening, then the throttle body size isn't the bottleneck.

 

Very true. So i have a complete ls2 intake with throttle body and factory fuel rails for about $300. Should I stick to this or sell it and buy the ls6 intake for a bit more $. Im not sure if the performance gains from the ls6 intake would be worth it.

 

IMO the LS6.
