LS6 Intake on an LS2? With all these comments about the LS2 intake manifold losing power on an LS1, I wonder if the LS6 intake would provide power on an LS2? The engines don't seem that different.
Seems crazy that GM would do that but you've got to wonder.

That combo would probably gain low end to mid-range, but hurt you on the top end. I really think that GM just made an inferior intake with more volume and a bigger TB opening because the normal vehicle buyer would not know any different. They were going to de-tune the car one way or another, so why not make a crappier (and cheaper) intake for the car? Since the LS2 has more displacement, it makes good use of the increased volume even though the flow characteristics probably are not as good as the LS6. Booo.

Here are a couple of dyno tests:

Any chance that they may test the TPIS mod'd intake or the FAST intake with 90mm Throttle body on that LS2 motor? I wonder if the LS2 intake works better on heads/cam LSx motors than the LS6, or if the LS6 still has the advantage? The torque gain across the board makes the mod a very good idea. Are there any issues on getting the LS2 fuel rails and injectors to mate up to the LS6 intake?

IMO if you are going to get serious about your cam and heads (something bigger than 230-deg at 0.050") and you are trying to make big numbers and hit the race track with some low ET's, then the FAST is probably the way to go. If you do not want to spend the bucks for the FAST, then you definitly want the LS6. I think the LS2 is a bust!
You might check with the guys over at SDPC (Kris) about using the LS2 fuel rails and injectors. I know you would need to change the o-rings on the LS2 injectors -- there may be more

check it out!
Yes, but you have to use spacers on the fuel rail because the LS1 injectors are taller then the LS2's. You will also need LS2 injector o-rings.
