I'd go with a FMIC kit, along with a bigger fuel pump. (WALBRO - $160 delivered, or BOSCH 040 - $180odd).
Then I'd upgrade turbo, something like a HKSGTRS, or HKS2535.
After that an after market ECU (WOLF3d, MICROTECH, PFC).
That should get you about 240rwkw if not more, after the ECU is installed and tuned.
After that uprade the injectors if you want to go sort of over 250rwkw.
If your going to get it into the 200rwkw power bracket, I would also upgrade to an after market clutch. (EXEDY 5 PUK BRASS BUTTON) personal choice again.. Can take up to 300rwkw.
Then you can go a head and choose some coilovers/suspension, plenty in the for sale section.
2 way LSD if you want, depending what your doing with the car.
