I have a 2000 Accord V6 3.0 EX COUPE and I am in need of options to install a newer model automatic transmission from an Acura or possibly the manual 6 speed that I hear can work from the Acura. Specifically, what transmissions including year and models will work with the j30 engine block currently installed? Also, can I swap the 3.0 intake manifold with a 3.2 from an Acura or any bigger available like one from the Honda Oddesy? Please be as specific as you can and include website links that help or can support your answers if possible. Thank you!!!
