Re: 4AGTE vs 2TG/3TGTE hybrid	Sun, 22 December 2002 20:11

horses for courses. the 2TG/3TG is a little old now, the 4AG is newer. specifically whats the difference? the 4AG is the big brother to the 2TG - the 4AG's got their design from the T series motor. ok, so we have two engines, 1.6 in capacity. sure, you want more capacity, use a 3T bottom end of 7A bottom end and you get 1.8 litres in capacity (NB: less bolts on 7A crank to hold flywheel on apparently AND not as revvy as the 4A - can't comment about the 3TG combo (Rod?). the 2T uses chain driven cam gears, the 4A uses a belt. the 4A doesn't have the dummy cam to drive the oil pump and the dizzy - dizzy is driven off the exhaust cam and the oil pump well thats drive off the front of the crank... i think if you're going to sink money into an engine - you'll get good rewards from both platforms - its what YOU want. sure if you're going to put one in a celica, the 2T/3T will bolt straight in - how easy is that - the 4A will require new engine mounts - no big deal. if you are a restorer and want some sort of authenticity - stick with a 2T (i'm talking celica's here) - if you don't care - throw in a 4AG) just my thoughts.....am sure there are much more qualified people to talk about both engines in far more details, but, at the end of the day its what YOU want in your engine bay!
