how hard is it to replace the IM?
 

I bought my gsr with the secondaries removed from the (stock) intake manifold. the whole dashpot assembly was removed as well...anyway, my buddy gave me another gsr manifold for free that has the secondaries and everything i need. how time consuming would it be to swap them out? what all do i need (tools and parts, i.e. manifold gaskets...)? is this even worth doing? thanks.

it probably would boost ur performance a little bit...but i dunno if it'll b that hard. this should help :) for an LS but i figure it should be similar :p

i just remember reading where some of the bolts are kind of a bitch to get to...that's why i wasn't sure if it was really worth it or not. also, why would anybody remove the secondaries in the first place?

didnt work? messed with vtec kicking in? messed with ecu? they stupid?
