ok, i just bought a 95 integra gsr that threw a rod thru the oil pan. i assume the head is ok but i was wanting to rebuild the motor and would like to do so in the most economical way possible while possibly having a little more power(would like to have 200hp at the crank....its going to be a daily driver so gas mileage is important). what would be my most financially advantageous move...to just buy a regular LS block and swap the heads or sell the head and just buy another used gsr engine or swap in an h22 prelude engine? any and all input is welcome. thanks in advance, take care

PS...i will be paying a friend to do the labor
