My 2 cts... The 2.8 is the 4JB1 engine and 3.1 is the 4JG2 engine, both engines available with timing gear and belt. Also, the timing gear set for the 4JH1 engine WILL fit both engines, despite having finer gears and thus much lower noise. However, the timing marks of the 4JH1 engine will not match the 4JG2 engine, it's off by 2 or 3 teeth at the fuel pump side, if I'm not mistaken.
Unfortunately, EFI engines are all timing belt....
Also, the timing belts for both 4JB1 and 4JG2 fill fit each other despite having different part numbers
