no, what you will end up with is a halfcut sitting in your garage for a bit over a year while cheap fuckers vulture shit off you. Most nga's who you think want to swap an engine will also want the gearbox and drivetrain to go with it, just like you do.
But hey, if you wanna sink 2.5k and not see the 2k you intend to make back in your pocket for a while then go nuts. If I were you, I'd spend a little extra and grab just the stuff you need.
Just sayin from experience.
