LS1 Lid on LT1
Thanks
Trending Topics
its fairly simple, just purchase a ram air box or LS1 air lid, go to homedepot and buy a 4x3 coupler with the clamps, just put the 4 inch one on the throttle body side and the 3 inch one on the MAF *maf end is a little tricky its very snug* then the maf and the lid just slide right on, you can use a clamp to clamp it down but since everything else is so tight that there wont be any air coming out

thats what that is.
i agree if your buying the ram air hood, might as well get the air box along with it.
im doing the ls1 lid swap on my camaro. im running a non funtional harwood ram air hood... i had to do some hacking on the ls1 radiator support to get it to fit.
i left my slp intake on also, next time i hit the track i'll do a few runs with each.

That is not an LS1 intake setup, its a '97 WS6 LT1 setup. To do the LS1 setup, you need the an LS1 radiator support/airbox base and also an LS1 air lid. I am doing my LS1 setup right now and that dang airbox base does not fit nice and flat on the core support like it was supposed to. We had to remove quite a bit of material from the underside of the base to get it to fit better. I need to get a second Fernco 3" to 3" coupler and cut it down so it will fit between the SLP lid and the MAF.
I am going to this setup because my old LT1 WS6 setup would not fit with the LS1 T/A front clip thats going on right now.
