a few quick questions will the ls2 intake manifold fit on the my 00 c5? If so what part numbers do I have to get with it. Will my stock throttle body work with it? Also what manifold came on the 05 CTS-V? Thanks every one...

The LS2 intake will fit on a 00 C5, but a LS6 intake flows better so I'd recommend that instead.

The stock C5 throttle body won't fit a LS2 intake. The LS1 intake mounts with 3 bolts and the LS2 mounts with 4 bolts. The LS2 throttle body is 90mm verses the LS1's 78mm. Then there's also a problem with the electronic throttle.

The 05 CTS-V has a LS6 engine which comes with the LS6 intake.

thanks for the advice on all of that the ls6 looks like the way to go then...

Going the other way around:

Will a '03 vette computer control the 90mm LS2 ETC properly?

I guess if an LS2 computer will control a LS6 TB then it would make sense that it should work the other way around right?
