look, the 3tc is the oldest of the bunch.. it is out dated, but i never once said anything bad about it... my first car was a 80 corolla coupe with a 3t and i beat that car to death, but yet it never died. like i said i like pretty much all toyota motor's. since everyone's on the deffensive, whats so wrong with the 4a?? again i don't have a probelm with your all's opinion, why would you care about mine so much? stop being so pussy hurt and get over it. any motor u pick is the right one..
