Anyone who knows how the drivingabilitys change if you mount a 20b in a RX7 fd3s. (its either a 700hp 13b, or a 1000hp 20b. It depends on the drivingabilitys and the costs, its clear that it costs more for modifying the 20b) Isn't the 20b about 16 centimetres longer and some kilos heavyer, that adds and moves the wheigt forward in the car. And is it much work to install the 20b, maybe the enginemounts have to be moved/added?

And what is the proper manual gearbox for the engine? I've heard that the Toyota supra gearbox can handle a lot of hp. Maybe there is upgrades for that box.. I have a supra gearbox i can buy now for 4000$.. I have access to adapters, so thats no problem if other gearboxes are better.. And what kind of rearaxel can i use, i can hardly think that it is possible to get upgrades for the original axel.. It must deal with 1000 horsepower.. Maybe a modifyed Chevrolet rearaxel?

Hope for answers, if not, i'll have to figure it out myself and see if it works.. Maybe someone else has a lot of horsepower in a rx7 who i can e-mail?
