Hey bro coming from the dsm community, like everyone said, the evo! The Gsx is my old car but i sold it because it was un reliable.I put down some nice hp numbers but it was down more then it ran.Evo is nice because one its new,two it has a warranty,3 cause stock its 271hp.The bone stock engine can hadle roughly about 400hp(4g63t)So u still can add on with out doing the internals on both cars.But evo hands down.
