Turbo 420a Runs Lean

[gs99eclipse]

I have a turbo conversion 420a motor. Right now it sucks to drive because it runs lean whenever you really get past 1/2 throttle. If you get on it anymore than that the AFR gauge shoots solid red. It surges and hesitates under hard acceleration, again 1/2 throttle on. The fuel system is stock and I know it needs to be upgraded. My question is what do I need to do so it gets enough fuel? Can I just swap in injectors from a GS-T? Do I need to get the ECU from the GS-T also? AFC? or a fuel cut out gaurd? Anything to help it out without breaking the bank.

you NEED a fuel system.stop driving it now or you WILL blow it up.youll need bigger injectors,a fuel controller,and a fuel pump.im pretty sure the 420a's use high impedance injectors,so no go on the stock turbo ones.a fuel cut stop box will not do anything,as your cutting do to lack of fuel.get an afc,190 or so fuel pump,and injectors sized for your boost levels.
