I want to do some cheap things to my 20SEH engine to get a bit more power.
I have heard of a RON plug mod?? Whats this then?
I also heard about bypassing the throttle body water piping. How does this give you more power?
I already have a 4-2-1 branch manifold and a K&N. I am also planning to modify the throttle body to increase flow (cutting throttle spindles and stuff).
Anything else worth doing?
