Looking for ideas to get me up over 250 to 300 HP, without cruching the bank. I am looking for direction please. Also looking for ways not to kill gas mileage too bad. With the ideas are there estimates as too the expected HP's with each change?

 

how much money do you have - only way to do that much is to go BT - plus supporting mods your looking at a little under $5000

 

To take a couple of steps back, which engine do you have?

 

$2400 atp hardware kit
sw - $700-900
injectors - $200-300

So for less than $4000 you can have what your looking for.
