Yeah im wanting that sort of power from mine as well, mine is getting rebuilt atm. another good option and one of the best is the bb gt3037r hks turbo or the blitz kkk. 60 trim is good for 1gs with the t3 exhaust side, you need a ball bearing turbo for real benifits and you will get to much boost spiking with an internal gate much better to use external setup.
Do it once and do it right, run 18 to 20psi with no worries
