Hi. I've just recently sold my car and am now looking to get into drifting. My choice of car is the SC300 but I'm unsure what engine to get the 1JZGTE or the 1UZ. The car will be daily driven and modified to take to the track. Whats the best pick? Also what are the common problems with both of them? It will be an auto then this summer coming I'll do a manual swap. I'm mechanically minded so will be able to fix most of the stuff that may go wrong. Any help/information about them will be great!
