Default LS2 intake manifold

Will the LS2 intake manifold fit on an LS1 engine? I realize it would take a different sized throttle body, but are the dimensions correct for fitment. Also, if it does fit does anyone know if it is more efficient than the LS6 intake manifold. Or would the LS6 or the LSX still be the way to go.

Search holds the answers you seek...

- yes it bolts right up to LS1/LS6 heads
- you need new LS2 fuel rails since the LS1 rails won't fit
- need new 90mm LS2 TB or aftermarket
- does not gain any power over LS6 intake on an LS1/LS6 setup

Cheers,

It does fit, with modification and a new TB. You might not gain anything over your LS1 intake though. The LS2 is a crappy intake. If you want performance and an easy swap, just throw an LS6 intake on.

somewhere on this board there are flow #'s between the FAST intake, LS6, and LS2 intakes on LS6 style heads. the LS2 intake flowed worse than the LS6 intake.

Could you put the LS2 throttle body on an LS6 intake?

No, the best you can do is a ported stocker. If you go any bigger than stock, the TB will be bigger than the intake opening, causing turbulance.
