why tell the guy to save the money or invest it, hell maybe he wants to spend money on his car and this is throw away money.
I also think you should consider supercharging your car. as hotmustang331 said it's really hard to get good power out of these cars N/A, not only is the motor small compared to a LS-1 but a bigger reason is the way the motor is setup, the valves are too small and the bore is tiny. These motors respond well to FI because they are choked for air with the tiny valves and small bore.
If you are going to stay N/A and you want more than 300 or so RWHP you better plan on spending a lot more than 4k.
