Fitment issues with an ls6 intake on an ls2 I was just wondering what fitment issues i would have if i pulled the trigger and wanted to install an ls6 intake on my ls2. What would i have to do to make this thing work, all help is appreciated.

After looking at a few small pictures of it. It looks like the TB bolt pattern isn't even close. The LS6 is a three bolt pattern and the LS2 is a 4 bolt. I can't tell where the MAP sensor is although it's probably in the back like the LS1. I'm also guessing that the FI O-Rings are the same as the LS1 so, you will need to swap those out. I don't think there is any OEM or aftermarket intake that doesn't have fitment issues.

Oh...Stupid me! The LS6 uses a 78mm TB so, you would need to get a new fly by wire 78mm one. FAST is gonna be easier if I can figure out the power steering thing....

I've got an LS6 inlet manifold with a cable 78mm Throttle Body here now atop the new LS2 in my car. I did it that way because my harness doesnt have fly by wire capability or the correct electrical connectors to suit the LS2 injectors.
So I re-used the TB , fuel rail and manifold off my old engine rather than buying more stuff.
Am still using LS1 28# injectors but have a set of SVO #30 to go in before the next tune. It does go hard.....very torquey.
Fitment issues were very minimal for me. You will have to reverse engineer a bunch of electrical connectors for yours though.

.
The intake itself will bolt right up and fit fine .... you're going to have to toss the LS2 throttle body and injectors, however. (i'm not sure about the fuel rail)
I really can't see all this being worth it for the small gain you'd see on a stock cubed LS2.

no no, not stock - stage 3 heads milled to 11.3:1 compression, 232/236/113 cam, headers, intake, exhaust. and partial tune with ls2 edit from jeremy formato. so do you think it would be worth it now, i was also going to have the ls6 intake ported and cleaned up. if you think this would be a waste of time let me know.
