Does anyone know anything about a swap with a Japanese mrt motor or a toyota levin...can either of these 4age be swapped do you think? I have motor and wondered if i can swap it out.

try it. . .

am thinking about trying it.......the 4age is turbo and already over 200...4ag is non-turbo and 160 horse and can easily be mod to 200+...gonna investigate and seriously think about it....

which 4ag are you talking about, stock usdm blue or red top 4ags peak out 108 hp stock.
some highly modded 4ag, with itb cams headers with kouki 7rib blocks have been known to push 150plus...
my choice for a swap would be 2zz..or if you have the money 3sgte...gonna be lots of work involved with eather swaps, i just wouldnt choose 4ag 16v or 20v...
my .02 cents..
