Is there a big bore to up the liters in our scion, if so how much is it and how much power do you gain. Or maybe like higher comp. pistons. Im just really tryin to figure this out cus after i/h/e and pulley i want more power for no more than 1,600, thanks for helping me out guys

 

Not available as a standard part anywhere, possibly custom work. It would cost way more than FI and give less hp/tq. The only way I know of to get significant power with $1600 is with a Nitrous setup.
