So I'm currently getting my gsr swaped in right now and figured it would be a good idea while they've got the motor out to build it up a bit. I was considering of course the basics: intake, gates timing belt, alt. belt, spark plugs/wires, and new water pump. Now I was also looking at these sk2 cam gears and was wondering if this would be a good upgrade to start with? Now as far future mods, Iv'e already ordered an sk2 60mm catback and plan to install a ZEX wet nitrous kit (75 hp). What else as far as engine mods would be a good idea to get? Any suggestions welcome!! Thx.
