Message i just cannot decide witch turbo would be better for my set up. i want a responsive turbo for street/highway useage and very little track useage. please vote and give reason behind your answer. i only want JWT Turbos.

dont need to be a dyno king. but i dont want a little more power than the sp500s put out. i dont want to have to build my trans up for crazy HP or have to worry about things breaking after everytime i drive the car.

some say just tune the 700s for a desirable HP and others say the 530s for their spool up. then some say i'll be maxing out the 530s. Greg from specialtyZ said both tubos magice psi is 20-21 pounds.

im thinking ~450HP to the wheels on pump would be a nice respectable number.

i'll have supporting mods for either turbo. take a look when its all said and done. i already have most of everything on this list already (most arent installed just yet):
