Ok, question, I'm thinking of putting a Z06 intake manifold on my 00. Question is what all do I need to get to do the job?

Will the oo parts bolt up ok, and any cutting needed?

Thanks for any help in advance

Hey Ernie,

The install is really pretty simple. You'll need 3 parts other than the manifold itself to get the job done. They are a new coolant hose for the front of the heads and 2 plugs for the rear. Here are the part numbers:


P/N:12568478 - the front pipe
P/N:12562788 - 2 of these plugs

For a visual perspective and another take on the swap check out Mel's site:

Thanks

Oh yeah, you might wanna keep an eye on the knock sensor wiring. It's a real tight fit under the '01+ manifold...

What kind of benefits would this modification provide?

I made the swap recently but have been too busy braking driveline parts to get a dyno number so I don't have an exact figure. I do still have an internally stock LS1, though...so the gain is minimal. I'd guesstimate 3-5 Rwhp/tq.

Now a head/cam engine will benifit a lot more. Somewhere in the area of 15-25 Rwhp/tq depending on how radical their combination is.

FYI, here are the results from a head flow test with and without certain intake manifolds. The numbers are in cfm...

My opinion is that putting a larger intake on a smaller port usually doesn't provide much improvement because of the turbulence the step causes. Cemo's post substantiates this. Port matching would definitely help. But grinding on installed heads, I don't know.

Cemo, Thanks for the info, i'll take a look at that.. and thanks for the numbers..

Roger,, I have heads and cam on the car. stage 2 heads ported and polished, w/ larger valves.

From what I understand that most tuners after and along with installing heads and cam package they will install the larger intake.

So that was the reason for the question.

Roger- I did not notice any difference in fit with the manifold upgrade, ie. there is not port matching problem. The change and benefit of the 01+ manifold to my knowledge is the volume of the extra manifold area. Just like the pre-01 manifold, it's cross-ram design incorporates decreasing runners that increase velocity like a trumpet but the 01+ runners are larger on the manifold side but end up the same size at the heads. This will create a more dense charge...

I was under the assumption that the LS6 intake ports were raised compared to the LS1's...but I didn't find this to be true. Anyone know for sure?

Thanks
