I'd say either pearl white (not bone white), British Racing Green (or any shade of dark green), jade green (or R34's Millenium Jade Metallic) or midnight purple would fit your car very well. Honestly it's rather difficult to think what colour will suit your car better since the wheels are green, and there aren't many race cars with green wheels to begin with
Also listing your engine and transmission inside the classifieds will help people notice your engine. There aren't many 2UZs around so it's quite interesting to see who has interests for it. I'd actually like to have one but sadly not only I don't have money, I don't have any other car that can fit the engine
