that was a serious reply. u didnt say u didnt want to touch the internals, and it being a 32 and old and u want to make more power from it, it's going to spin a bearing in the future, its a given.
but if u dont want to touch the internals id suggest the following:
exhaust - 3" cat back, hi-flow cat, trust extension front pipes
boost controller - blitz ID3 (run 15psi)
power FC
fuel pump - dpends how much power u want, bosch 040 or 044
injectors - depends how much power u want, sard 600's or the like
suspension - sk's group buy
brakes - new rotors & pads (DBA 4000 with ferodo ds2500 fronts and racebrakes rbf74 rear)
oil cooler - one of those $340 from performancewise on here
clutch - Jim Berry full monty
Turbo's - depends on what condition the stocko's are like on ur car, i've got a set of R34 turbo's for sale, they're in great nic and u can pump an easy 16psi through them
theres an easy 10k once its all installed, but u'll have a nice all round gtr
