The amount of money you will save, will buy you the things you need most ( EFI harness, 120k kit, hoses, ect. ). Plus all things you will learn about your Z will save you a ton of money and time later down the road. There will be times when you are so pissed you cant think straight or times when everything seems to go wrong. TT.net is here for you. We will help walk you through this. What ever you do, do not take short cuts. BUY A NEW EFI harness. This will save you a ton of time in trouble shooting. Trust me. It will be the best $ 400.00 ever spent. As far as a front clip goes. I have tried that before. I would say no to this. You would think it has everything there and you have no other exspences but that is not completely true. Alot of things will still need to be replaced.
