If you've got 5gs minimum to spend I'd do a compression and leakdown test to make sure engine is in good shape then go with improving your head (new valvetrain), and and block (lower comp pistons, rods, sleeves). Then piece together your turbo kit (manny, turbo,waste gate, pipes, IC, bov, turbo timer/boost controller, etc.) All that should be about 5gs w/o installation. Then get some wider (if not bigger) wheels drop it w/ springs and aftermarket shocks, or full coilover system (tein ss w/ EDFC), upper, lower, rear, front strut bars, etc. tons of stuff to do to it. If that was a typo and it was 5gs maximum then do the suspension mods 1st, no point of being fast if you cant put that power to the ground. Congrats on ur purchase enjoy the ride.
