Hey guys so just a couple questions I'm looking to start getting some mods for my 2004 ls1 gto. I've seen a lot of LS cars with the FAST lsxr 102 intake manifold and was wondering what your opinions were on it and maybe when along the process should I get that part. I'm really looking to build my ls1 to the max. But don't know where to start or what parts. One last question would it be possible to achieve somewhere in the 600+ hp range with an ls1? If so how? Thanks guys!
