Answer 1

Well Kinda odd that u want the fps that high but... ok. Hers the parts u need and on a budget G&P white piston, Systema M130, You should probably jus get the echo 1 aluminum piston head, some high torque gears, shims, and metal bushings. All in all you would b spending about $120. Hope this gives u a good idea.
