Hiya to everybody! What I've got is an auto civic eg5 (D16Z6 engine). Now I want to take off the auto gearbox completely from my engine and put the manual on. Has anyone done this before? Do I need any modification to the ECU?! One more question: I can only put a D16Z6 one or a B16 tranny will fit as well? Anyone who knows about it share with me please! Thanks very much indeed!
