limited $$$ rebuild? fuel management? ignition?

I have a 95 civic si hatch with a stock block. i put a t3/t4 turbo on it with intercooler, BOV, boost controller, injectors, and VAFCII. the motor still seems like its in good condition with no knocks or pings and it burns little oil considering a bolt on turbo. I'm having problems getting my priorities straight because of limited money. i want to know how i can best spend $1000. should i keep saving and have to motor fully built? or get more fuel management with maybe a data log or do a full ignition system?
