I have 88 7mgte auto trans needs engine only I Plan on ordering a 7mgte from Japan running it stock until warranty goes out an installing my mega squirt ecu I have a 0.55 trim aireasearch turbo with 36 inch by 12 inch front mount intercooler and the 2007ish pink greddy bov plan on going for 450-550 engine hp. I plan installing the 2 mm metal headgasket and arp head studs to the correct specs and 3inch full exhaust.after warranty and moving turbo oil return line to the oil pan bcuz I've heard it also slows oil down goin through the filter first instead of straight into the pan and it's an easy fix is this true? Not sure what injectors to use to accurately get the right fuel with my set up anyone know?? I've heard your wasting your time doing internals if or only going for around 500hp is this true on low milage engine? And not sure the weak link of engine over 550hp?? And does Anyone know size/kind of waste gate I should run the mega squirt says it can control boost at different rpms and don't know what I need to be able to do that. Any suggestions would be appreciated any advice if I need something else please help and let me know thanks for the help everyone!
