Have just acquired a 93 GTR 32s.. In Manila, yes you can find parts here but of course not that easy and usually on order basis. Surplus shops sometimes have used parts, while brand new one's will come from tuner shops like Emperor Motorsports, DMF (they have used parts too), and Autoplus.
My Godzirra is currently being checked and recon by an ex Nismo mechanic, just making sure she's ready when I take her home then she's off to a buddy's shop for repainting. I'm thinking black or gunmetal as her next shade (she's currently silver). Your steed, she running how many horses now?
