I have some ideas for you since i build cars, theres shaving the head, cams(crower stage 2),aem true power pulleys,raceing wires &coil, ajustable camgears,chips, coldair intake,and thats just the surface of it all.
if you have an at tranny you can get a tranny overhaull kit and it will be alot cheaper to do all of this then a swap. trust me all of this will give you a great amount of horsepower, the pulley themself willgive you 2 1/2 horses and about 15-20 extra miles per hour.
