Okay, This is my first post here...I need help with my ra40. Right now, I have a 22r in it. I was thinking if I can put something better into it like...7mgte, 4agze, 4age or the 22re. But here's the problem, my cars a carbie and I was wondering if swapping it for a fuel injected will be easy. Hoping somebody here can help me because everybody in the US know sh*t about this car.
