theres a massive thread about this floating around...BUT when i did my lq4 swap into my 99 t/a...i had to swap....
-i would swap the flywheel to keep it with the same converter
-drill a hole for the alternator bracket
-swap crank pulleys (theyre different)
thats all i can think of right now what i did when i swapped

The swap for me wasn't too hard, but you do have to relocate a couple of ground wires. I would highly recommend tapping a hole for the alt bracket. Napa was the only place that I found that had the correct tap in stock
