I can get a ls2 intake manifold complete with injectors and fuel rails for rather cheap, and Im thinking of swapping out my stock ls1 intake. Would I see a bigger increase in power over a ls6 intake manifold? Anyone have any ideas?

 

wont see a big increase over the LS6, plus the LS2 used a different 4 bolt throttle body.I think someone makes an adapter so you could use an LS1/6 style TB on the LS2. I guess it depends on how much your getting it for an LS6 usually go's for about $300.

 

there is no need really for a 90mm set up on a stock cubic inch ls1. now if you have a great set of heads and cam you might see a difference but you would send just as much on the ls2 intake that you would on a fast 90/90... for go with a ls6 or a 78mm fast setup.

 

Thanks for the info..I guess I will just get a LS6 intake and try to find some LS6 heads.
