Mate, just have a look around. Can pick up Hybrid FMIC kits for $650 off ebay, second hand vf35's/34s for a little over the thou mark. Injectors for about $400, fuel pumps $250,
ECU's i picked up an apexi powerfc for $900 plus $200 for a z32 afm but this has since gone up in price. Shop around, think about stuff before buying them and it will take time to get there but i found its better to mod a bit at a time. This way there is more satisfaction with every piece of gear that goes on.
