i dont think if it get a type r motor i will need to do much to upgrade in the future. and a close to stock itr will have less problems then a stock GSR at 10psi. and i think i can get into the 12's without even spending that much money on a itr. with the mugen headgasket i got, my compression will be at 11.4:1. The transmission gearing is perfect for 1/4 mile. LSD. some mild cams (buddy club Spec III or similar) would only cost around $600. and probably by next summer, i'd like to upgrade the throttle body...ITBs. then some tuning. the total cost would be right around the same as a turbo gsr. but i like NA better, and i really think once the tuning is done, the car would be much more reliable then once the tuning is done on a turbo car. im just not a fan of turbos.
