I might have found someone that is upgrading their GS-T and is selling the turbo, intercooler, 1g BOV, mid-pipe, and down-pipe. My question to you guys (the experts) is where can i get the exhaust manifold that will fit our 420a? Because I know the 4g63 is different all together. I know I will need to customize intercooler pipes for my car, but main concern is exhaust manifold. Also, what would i need to put on my ecu so that it can happily read the extra boost? I know I will need fuel upgrades (Fuel Pressure Reg., fuel Pump, Injectors) but ECU wise what do I need? I am interested in doing this work myself rather than buying a kit because it gives me the freedom to take my time and do something different. Any advice, answers, suggestions, etc.....Deeply Appreciated
