Bone stock 1991 300ZX Twin Turbo. What's the first performance upgrade i should look into? I know i need to get a turbo timer. I was considering the Blitz FATT DCII turbo timer. Intake? Exhaust? Chip? Turbo upgrade?

How much money ya got? It all depends on how deep your pockets are. If you can afford to get a lot of goodies at once, more power to you. Usually the simplest upgrades are done first. Intake, exhaust, gutted cats/downpipes,pulley, ignition upgrade, flywheel, intercooler,boost controller, adjustable cam gears, larger injectors, ECU, dual intake filters, turbo upgrade, exhaust manifolds, cams, extrude honed plenums, bottom end (pistons, rods, or stroker kit), heads (titanium valves, guides, springs, valve job, etc). Most of this should be grouped together (done at the same time). The more you do at one time the more dramatic the effect, obviously. Don't forget you'll probably want to leave room in your budget for suspension, wheels and tires, possible body kit, interior accessories, and so on.
