You only would actually need to do any sort of fuel system if you plan on boosting... so if not, dont bother with the fuel. what motor do ou have?
If i were you, i would sell haf that stuff and swap, OR boost and continue with the Fuel upgrades. Of coarse if you do end up boosting, you will also want to build up the internals, if you plan on running more than 8 PSI. With a turbo, set a POWER goal, not a PSI goal (this will save you from getting flamed later on)
So, to summarize....
1) Swap ou the motor, sell the old one, to help with the cost of the swap.
2) Boost your motor. Build internals, Eagle rods, JE pistons, or wiesco pistons, sleeves, ARP bolts, studs all around. Upgrade your fuel setup, bigger injectors (450 and up), FMU, pump, etc.
My vote would be to swap, and then evetually build the swap for boost... hope this helps you decide.
and yes.. this is hondaswap, not
