I've got a 00 RS and am seriously considering building the stock block, IE JE pistons and rods, Cobb heads,cam, and titanium springs and retainers, port and pollished intake manifold, and all new gaskets and all that good stuff instead of doing the WRX swap like EVERYONE does. I've already got a ZEX nitrous system with two 10lb bottles. After the block was built up, I would switch from a single fogger system to a direct port system. Has anyone built an all motor RS up? If so, how did it do and what kind of power were you making?
